something is still missing

Thanks for taking time to respond to my problem. The stereo guys hooked up my door and back speakers to a Massive NX2 amp.I believe it is a 2 channel but you can only hook up 2 sets of speakers to the amp.
the new speakers are Hertz(ht25 as the tweeters and ecx87 inback and 6x9 triaxil in the door). The amp does have a Hi-pass filter setting on it.I know that the speakers aren't hooked up as component speakers.Was it a component in the 1st place? The Nissan dealer couln't locate the amp and neither could these stereo guys (that was recommended by one of Nissan audio guys.I just want the whole range of frequencies. It's not like I listen to loud music all the time. Most of the time medium volume.It doesn't mean the sounds can't be crisp and sharp. I would appreciate any suggestions. I have a 2010 roadster w/ the Bose that also has the Navigation system.
Thanks,
Z Me Fly

This is a odd setup that's for sure. Should have ran the front's off the main amp and the rears off the deck amp, the rears can handle way less power typically then the fronts due to their small size. That would give the correct balance control fader from front to back, but it sounds like the front stage is a mix bag of 6x9 and a tweeter? No wonder you find the tweeter range in the front sounds overpowering, there are 4 tweets in the front stage with the 6x9's included. Plus with the rears tied to the doors they are both at the same level so you can't fade the back end out to focus the fronts? I think this Audio guy maybe needs a lesson in sound staging? Who would ever put a 6x9 back in the door, I have a touring with Bose which has the 6x9 door setup. I just made a bracket to mount in a typical 6.5" woofer, I am thinking if you adjusted your gains in the main amp you might get a better sound level match or maybe not.

This is just my humble opinion but I'm a guy who has a deadicated media room in his home, I have alway's had custom systems in all my cars including my current FX. I'm not claiming to be any kind of expert, but don't you think by not using the supplied cross over that the manufacter supplied your compromising the sound that the manufacturer had intended for you to hear. Not all cross overs are made the same. Keep in mind they spent many hours in RD and countless dollars to. Have them use the supplied crossovers and then go from there.
Kindest regards,
Tom

Hey Tom,
I agree that crossovers should of been used but these weren't component speakers. I wanted components but I don't think he had 6x9 speakers in a component set. Is this why the sound is not all there?

The 6x9 route is the source of all your problems. Get those things out of the doors and install a proper 6.5 component setup, end of problem. Then run the rears off the HU amp, the rear 3.5" all they need is 20watts rms.

My current setup which sounds great by the way and easy to control. I have a set of POLK DB's running off a Rockford Fosgate Punch 300-2 which rocks, I also have a set of Boston S35's for the rear which I powered from the HU amp and these also rock. Plus the subs.

I have excellent total system control with my current setup, I can fade or balance any single component that I want. The components are easy to install and setup, 6x9's are nothing but trouble.

I can see why he went that route considering that was what the stock Touring bracket is setup for, but everyone has been just making a 6x9 MDF panel for that bracket and mounting the 6.5" driver in there. Works really really well, I would save your $800 buy a set of high end components and never look back.

Okay, now I'm confuzzled...

Is it the NX2 or NX4 you've got?

Locate which amp? The factory Bose amp? If no one found it (it's behind the seats underneath the plastic shelves), how is the NX2 (or 4) hooked up to your stereo head unit?

Agree with Juleous: you've got at least two extra sets of tweets, the ones in the dash are sufficient. Replace the 6x9 triaxes (3-ways, right?) with a component woofer (can you exchange those 6x9's?). The rears can stay, but I prefer just a midbass back there for rear fill; if I run rear fill at all.

You got some nice stuff there - but picking good components is just part of the battle. As you probably know, a proper install makes the most money.

yes, I called and they are going to replace the speakers with components with a croos over. As far as the amp goes,I upgraded to a NX4 that will take 4 inputs. I use to be a stereo guy but it has been sooooo long ago. I was thinking to have them put in an equalizer. My thought is that I could tune the freq how I want. Is this a good idea? How should I have them wire it correctly. They are receptive to the forums suggestions,as I printed them out all my replies from all of ya'll(from Texas). I am extremely appreciative of nice total stragers helping me out. Ya'll are great.

You have a 4 channel amp, with that you could run front components off one channel set and then the rears off the other. Only problem is that's not an effective use of the amp, as the rears that fit in the factory location are very small. 20 watts is all you need there so I would suggest you wire the rears upto the Headunit amp rear channel output, then run your components off the amp with 4 channels bridged into 2 for max power to the front components. This would be a better setup as your front stage is your focus, so send the power there.

Third option is if your using a sub, then I would have the rears off the HU, the components off 2 channels on the NX4 and bridge the other two channels into one for a subwoofer.

This I think would be the best use of the power you have available in the car. Giving the power where it's needed most, highest power to the sub, medium power to the components and lowest power to the rears.

This setup would give you full fader control and subwoofer control also. Only other suggestion would be to look at a 2ohm component set to pull maximum power out of your amp. If your a tweeker then get a Digital EQ from Audio Control with external interface, otherwise don't bother your HU can tweek the basic treble and bass settings.

Just my suggestions, not a huge amount of options in a little car like the Z.
