Subwoofer & Amplifier Install...
 
I have a Kenwood DNX9140 which I am going to install and I'm planning to get a subwoofer and amp for this DVD/Nav player for my Nismo 370z. Which brands should be OK and how to configure them? I'm new to car audio system so any suggestions would be appreciated.

bigaudiofanat 09-16-2009 11:55 AM

In order to better understand what you are looking for, I am going to ask you a few questions. What kind of music do you listen to? What is your budget for everything total? How loud do you want it to be? As for adjusting them and all that is basically the same for any amp and sub. If you go to car audio 101 thread there is some helpful info there that will help you understand a lot about tuning and such.

lordsii 09-16-2009 01:44 PM

I usually listen to Rap and Hip Hop. I wouldnt mind the spending limit but reasonable price. And I'm not into top of the line models. Thanks.

Get a JL10/12'' shallow mount W5 sub... get a phoenix gold 600watt amp

bigaudiofanat 09-16-2009 01:58 PM

I am going to disagree with the JL sub. Over priced and not the best for the kind of music he listens to. I am going to recommend a alpine type r 12 inch sub for your setup or a Rockford Fosgate Punch stage 3. For amps I do agree with your phoenix gold amp or you can go with a kicker amp to save money. When you order your sub make sure to get the DVC 4 ohms which means there is 2 voice coils that are 4 ohms. This way you can hook it up to most amps.

www.woofersetc.com

or

www.amazon.com

are good places to get your sub and amp. Also do not forget your power wire and rca cables as well. I recommend kicker hyperflex 4 gauge for power wire and rcas stinger is pretty good.

lordsii 09-16-2009 02:08 PM

bigaudiofanat,

It sounds a bit stupid but can you point out the model #'s for the amp and sub (and maybe enclosure for my nismo 370z?) and accessories like wires/cables ? And where to buy them? Honestly, I know nothing about car audio but am trying to learn it since I've got my Nismo 370z...

bigaudiofanat 09-16-2009 02:42 PM

Sure thing I will make up a list and either post it or send it to you.

bigaudiofanat 09-16-2009 02:55 PM

For a mid to higher quality sub and amp here is the setup I would recommend.

Sub
P3D412 - Rockford Fosgate Punch Stage 3 4-Ohm 12" Subwoofer

Amp

ZX750.1 - Kicker 1 Ch 750 Watt ZX Series Amplifier

Power Wires the reason I choose kicker is because they have a very good quality wire and very easy to work with.

Amazon.com: Kicker 05PK4 4-Gauge Single Amplifier Power Kit: Electronics


RCA's
Stinger makes some pretty good rcas and you need a quality set so that way you do not get much noise interference from other electronics in the car.

Amazon.com: SHI2312 - Stinger 12 foot - 2 Channel HPM3 RCA Cables: Electronics



Now if you want to get a little better quality here is your other choices.

Amp

X600.1 - Phoenix Gold Xenon 600 Watt Mono Amplifier

OR

PDX-1.600 - Alpine 1 Ch 600 Watt Digital Power Amplifier

Sub

KAPPA PERFECT12VQ - Infinity Kappa Perfect Series 12" VQ Series subwoofers

IDQ12V3.D4 - Image Dynamics 12" IDQ Version 3 Dual 4 Ohm Subwoofer

Now the reason I choose the subs I did was because not only your taste in music but how much power you are going to probably be running and also your budget. Any combination of sub and amp would sound good from this group. If you wanted me to choose I would choose the PG amp and the ID Q sub, I think that would sound pretty darn good. Also JL DOSE make some nice subs and yes they sound good but there are better ones out there for the money and will also sound better.

bigaudiofanat 09-16-2009 02:56 PM

For a box that will fit I would look at z enclosures for there boxes will fit perfectly.

2fast4thelaw 09-16-2009 10:26 PM

Alpine offers a big bang for the buck. The Type-R subs are really decent and thier amps are pretty solid. If price isnt too much of an issue I would go with the PDX line but the others will definitly do the job for a lot less.

The component speakers arent bad either. I had a set of the Type-R's before and they sounded pretty good for the money.

carfr3ak 09-18-2009 10:56 AM

About pricing, call up your audio shops who are authorized dealers and ask them about their pricing, and if they can match the prices you are finding on the internet, in most cases, they will and even do better.

I got my JL Stealthbox for my SUV for much cheaper than I could online, not only that, but they installed it for free. Most important thing is that I bought it from, and had it installed from an authorized dealer, which means I still get to keep the warranty that comes with it. Got my PDX 1.600 sub amp from them too, also at a fantastic price.

Cliff notes: Try not to buy online to save your warranty and to potentially get a better price.


Note: Watch out for shady audio shops who can get you a better price, but charge you for installation. Stay away from those.

bigaudiofanat 09-18-2009 11:02 AM

I always buy online. Most shops do not carry the higher quality names that you can find online. Nor are they willing to get the product or honor the warranty it comes with. Yes some shops carry JL but there is so much better out there than JL. Like audison, Rainbow, Focal just to name a few.

carfr3ak 09-18-2009 11:11 AM

I don't know what kind of audio shops you have in your area, but I never ran into such a problem. You just have to do some work and call around. If they are an authorized dealer in the first place, I don't see why they can't special order an item they don't carry, while still giving you a great price that includes installation, which is exactly what my audio shop did.

When they didn't have my JL Stealthbox(of course they wouldn't, it's vehicle specific), they ordered it for me. I'm not saying he goes with JL, I only went with it because they are one of the very few companies that make vehicle-specific sub boxes that take up very little space and are designed to be incognito.

Tip: Go straight to the manufacturers website, and use "Find a Dealer".

lordsii 09-18-2009 11:20 AM

I agree with bigaudiofanat. Most of the shops try to rip you off especially when you buy high end products and when you bring your sport car in... Not only that, I'd prefer installing it myself so I can get familiar with my car and learning car audio systems is the most important thing to me. Speaking of this, I'm sure there will be tons of questions from me when installation comes like how to bypass Kenwood DNX9140, how to wire subwoofer/amp, etc? I'm going to receive stuff next week so I'm kinda excited now.

Bigaudiofanat, so IDQ12V3.D4 - Image Dynamics 12" IDQ Version 3 Dual 4 Ohm Subwoofer and PDX-1.600 - Alpine 1 Ch 600 Watt Digital Power Amplifier are a good match?

Thanks again.

carfr3ak 09-18-2009 12:05 PM

It's another thing if you want to do everything yourself. I still don't see how they will try to rip you off if you call them and ask them for price of a specific sub or amp you are looking at. What you're basically telling me is that once they see you roll up in your 370Z, they will "forget" about the quote they gave you over the phone. IMHO, doesn't make any sense. But since you are going to do the install yourself, you don't have to worry about such things.

GL with the installation! Let us know how it goes and post pics :tup:

Correct with all your statements and questions. I look forward to the questions and all. I think you are going to enjoy that sub if you want to get a but nice amp go with the phoneix gold. All and all your going to be happy. Yes shops like to over charge you or make you think you are getting a good deal. I never go to a shop for an install nor to buy products much cheaper online and much better selection. Also Almost all my local and some that are farther shops I do not trust at all. That is one reason AK came to me for the install and many others. They do not want to get screwed and they want a quality install.

Correct they can give you one quote and you can even give them what car it is over the phone if you want. Than you get there and they will be like oh well you have this model so we have to get this to make the ignition system interface with the head unit or some BS like that. I do not like how they try to get more money out of you. I have seen it to many times.

This is the farthest thing form the truth. ALL of the brands you listed above must be bought from an authorized shop to get a factory warranty. Online companies will offer inhouse warranty which can be nothing but headaches. Whenever possible it is best to buy froma local shop, Its what keeps this industry thriving. You can get close to the same prices as you can online if you go about it the right way :)

speedfreak28 09-18-2009 03:05 PM

There are plenty of reputable shops out there. Most of the highend brands are very particular about the people they let sell their product. It seems that buying online to save money is a great idea but most people don't realize the effect it has on the Industry they love.
Say I own a shop and you decide to buy it online instead of paying the 100 extra it costs at retail. The sale that is taken from a local business leads to them shutting their doors and leads too less product sold for that particular manufacturer. This is called the race to zero.
Its the reason why alot of the brands that used to be quality are now junk. Decreased volume leads to outsourcing to save money. Fosgate and kicker are just a couple examples of product no longer made in the US. Most people dont realize the effect of buying unauthorized equipment online. Find a reputable shop tha carries the high end brands you want and most will meet you half way on pricing.

bigaudiofanat 09-18-2009 07:08 PM

I have to disagree, I think people buy online is to take out the middle man. Also to make sure that they are getting what they wanted and the way I look at it is more of a trustworthy way to buy online. Also yes some companies are picky on who they let sell there product. But on the same note not all shops even sell the normal brands. I know of 2 particulars shops that use to sell alpine, jl, kicker, and focal. Now they only sell kenwood, polk, clarion, and bull dog for security. Do not ask me why that happened to them as I do not know. All I know is when I want to buy something I want to buy it not hear aw well we can get it but you will have to wait or well we don't carry it but for a few extra bucks we can get it for you. When I want it I want it. I think that is most people as well.

Lets say you buy it online, sure you may be cutting out the middle man, not only that but most likely you are cutting out the warranty also. Most online retailers are not authorized retailers(except crutchfield, etc, but it's not any cheaper @ crutch), so when your sub blows or amp gets fried for some odd reason, instead of paying the extra bit of money, now you have to shell out for a whole brand new one. And honestly, there are easy ways to find out if a shop is trustworthy or not.

You get what you pay for, and that doesn't apply to just the quality of items, but also the benefits of Where you get it from.

I guess you should call the other audio shops besides those.

This is why you call up shops and you shop around. Use yelp or some other review website to find out if the shop you are calling is good or not. Hit up your local forums, there's countless other ways to figure this stuff out.

The only time you are getting what you want, when you want it, is if you go to a store and they have it in stock. Otherwise, whether the audio shop orders it for you, or you order it yourself, you are going to wait. Unless you are going to order it online and overnight, which in that case, defeats the purpose of getting it cheap online, And losing warranty.

IMO: If you are going to do something, do it right. Just like how I wouldn't leave the store without an extended warranty(which has already paid for itself many times over, even though I buy great quality brands). But in this case, instead of getting an extended warranty, you completely cut out the warranty because you want to save a few bucks.

Graybullet 09-19-2009 08:33 PM

Buying online is not always cheaper ( new items).

Some audio shops here purchase their equipment from the manufacturers just like online stores such as Crutchfield. Also, while its true that majority of the time the online stores carries way more than the old brick n mortar, the latter might provide a cheaper discount (on the two or three brands they do push)than the former because they have a contract to push those specific items. An example..my JL stuff ( i know i know, its overprice overrated ;) )that I purchase from the brick n mortar was much cheaper than Crutchfield...that's with tax. The manager told me they have a contract with JL to push ALL their items and have them readily available..and in return, provides them with discounted already whole sale prices (this store is also on JL's signature retailer list)

Just my business commentary :D

Im only 30 miles form you and theres plenty of reputable shops near me. Buying online is not taking otu the middle man lol. Your buying an unauthorized product ( serial numbers scratched off on woofersetc.) that has been obtained illegally in most cases. Usually its bought from an authorized dealer or distributor reselling bulk to make a quick profit. Trustworthy? not so much. The other issue with an in house online warranty is products like amps arent replaced, theyre repaired.

M.J. 09-20-2009 03:14 AM

I was able to pick up most of my stereo components here in Hawaii for about the same price as the stuff on ebay. I wasn't able to get everything from one store but I looked at the items I wanted, asked what they were asking for an item and just made a cash offer of what it would cost me to order from ebay. In every case the stores said yes. My Alpine head unit, the Alpine components, my rear speakers, yup rear speakers (: both amps and my JL subs.
Okay sorry. I didn't mean to get this thread off topic.

1. not true most online places have warranties and service for the things you buy. You should not have any problems with speakers or subs even amps if it is all setup and tuned right.

2. I hate going to shops never will go to them. If they do not want to get what you want than you are going to hear a speech saying how you should buy this one and not that one.

3. As I said before and it applies for everything in CA and cars as well. Everyone has an opinions about the right way to buy things or do things. Dose not mean they are ALL right but most of them will get you the same or close to the same results.

1.As i stated earlier, besides crutchfield, most warranty work is in house and is usually repairs

2.Not true at all, dunno what shops you go to but authorized retailers use local distributors and can have almost anything in a day or two


3.Sure there are different ways to achieve similar results but failing to recognize the effects of Internet sales on those industries has lasting negative effects

ConchZ2 09-21-2009 09:09 AM

One of the biggest problems with buying on line is the potential for “grey markets” products. They recycle the same refurbished defective units over and over again to innocent unsuspecting people.

bigaudiofanat 09-21-2009 09:57 AM

Not true on crutchfield or woofersetc. If they do sell refurbished stuff they let you know they are.

speedfreak28 09-21-2009 10:28 AM

You are not very educated about woofersetc practices to obtain product. All of the higer end brands are obtained through unauthorized sources and have the serial numbers removed.( jl focal, zapco, morel, audison, boston acoustics, JBL, memphis and plenty more) None of those products are authorized, the companies wont honor any implied warranty either.

bigaudiofanat 09-21-2009 10:40 AM

The refurbished stuff they might not but I just emailed them they confirmed that most of there products the manufacture will honor the warranties. Kicker, alpine, sony, clarion, kenwood, polk, and others they will. I sent them a reply asking about audison and such I have not received a reply email yet. But most people just buy on ebay anyway so weather you buy from ebay amazon or woofersetc most will not have warranties.

Id love a copy of the email with any of the brands I listed being authorized, not authorized through woofers, through the manufacturer. So now your saying that most stuff bought online wont havea warranty? whats the point then?

speedfreak28 09-21-2009 10:47 AM

Its the same way they bought all the rainbow equipment, a distributor went out of business and they bought there stock. Now Theyre claiming to be authorized. Not by rainbow.

I never accused “Crutchfield” of sell selling used/refurbished defective units as new. What I’m saying is there are sites on line that do and YOU would never know the difference.

sounds liek a bunch of BS sales gimmick, They are not allowed to ship any of those products I mentioned or sell under MSRP if they are a dealer ( ask me how I know) Do you really think Woofersetc is gonna say yea were not really supposed to sell those brands and its not a factory warranty?;)
