New speakers don't sound good
 

Hey everyone, I thought I knew what I was doing but I guess I'm just a novice when it comes to all this so I'd really appreciate some advice from you guys that know what you're talking about. I spent about 600 with installation for a set up that I either had way to high of an expectation for or the guys didn't install correctly. I got my care bone stock, btw.

After decinding there is no room for a sub I went ahead and put more money into getting better speakers, polk mm. I went to a shop to have a guy install them and they ran into some complications. When I went to get my car it sounded terrible and they said that the guy who installed my HU just threw all the wires in so they couldn't tell what goes where. They told me to bring it back the next day and they'll finish it. Next day, I got it back and it seems fine. Some of the songs I play make the speakers sound like they're pooping, other songs make it sound like it's blown out and rattling, and some songs sound fine, just fine.

I have the polk MM 6501 with the JL Audio JX360/2 amp. I'm rationalizing and saying that maybe the woofers can't hit those frequencies with some gongs but then that doesn't explain the rattle and the fact that the stock ones could. They just don't sound like $200 speakers. The tweeters are fine, very loud and clear. I remember the crossovers were an issue. I heard them saying they connected it to the tweeters but common sense tells me they just go to the woofers. But then they added an extra pair soo I dunno... help? The speakers came with a pair and I'm assuming it would just be hooked up to the woofers and the tweeters are just there.

I also got a Pioneer TS-SW3001S4 12" shallow sub and got rid of the spare. The amp that I plan on getting is from a friend. It's a rockford fosgate super tiny amp that I think is 300 watts. This is all waiting on a box to be built before installation so if you see any problems let me know!

I'm really upset. I love bass and I understand the speakers aren't going to come close to a sub but the quality just seems so bad. Regular rock songs and most rap and hip hop sound fine, but holy grail, what's your fantasy, and some edm songs really screw things up. I just don't know why I paid so much to have speakers that sound the same sans the distortion at high volumes. Any help would be nice guys. Thank you

edit: If it helps at all it's set up at 4 ohms

sounds to me like an install issue. I would have been wary once the shop guys told you they couldn't figure out where the wires went because of the last guys install. BS, straight up. A professional shop would have started from scratch, never trust someone elses wiring when you're putting your name on it.
I would look first at your crossover networks, since that was an issue they pointed out to you... It may be that they didn't use them on the woofers, and they are getting low frequencies that they are not designed for. Also, if you are distorting, your amp gains need attention. Take it back to the shop before you blow your components, and have the guys you paid to do the job get it right, or get a refund, and have someone else fix it.
If these clowns can't hook up a simple system like this, run far and fast, and shout it from the rooftops so noone else gets robbed.
Hope I helped.

From experience, any decant after market audio system with amp (even if junk) sounds better than stock. I suspect a crappy install. Another thing to consider is that not all speaker are meant for a specific sound. You have to shop specific speaker for specific type of sound. This "may" explain why certain songs sound good, bad, crap in your set up. Only advice I have at this time is to let the shop finish the install since you have already paid them. It is a very small chance that you can get you money back now. If Your system is still not up to par after they fiddle with it, find a friendly local that knows a thing or two and have him/her take a look.

I have a feeling poor install as the others said. Completely agree with Ron on never trusting someone else wiring. If your popping on certain songs I have a suspicion they might of even bypassed the woofers crossover and ran them straight to the amp. Or they didn't set the gain and or filter on the amp. Or could even be the wrong RCA signal going to the amp.

Sounds very similar to my situation. Took them 3 days to install a new HU and alarm, said they had all kinds of issues with the alarm. My S Mode stopped working after I drove off, the key fob light came on and never turned off and the speakers sound like crap. Took it to the dealer and they said the wires were spliced in places they shouldn't be, just a disaster of an install, wonder if we went to the same place.

It's a shame some of these shops out there are doing they work they do if you can even cal it that. Yours will be taken care of soon :excited:

Is the Z's wiring more complicated than a normal car? Is the Bose setup messing up the installs? It's pretty odd that myself and the OP have almost the same issues.

No the z is a pretty basic car, the bose system just makes it a bit more difficult to install aftermarket speakers and such but still about as hard as any other car.

I'm pretty sure it's a poor installation and a possible blow out of one woofer. They really pushed it during the whole trial and error tuning. I'm just gonna have to take it somewhere for a check up once it's all done. Just for my own reference, the crossover goes between the tweeter and woofer to control what goes where?

And finally, the mm have a 2.7 decibel or something and to me that means nothing but I know it's something unique and I'm thinking the installer doesn't know either. Thank you guys for all the help again. :tup:

What they really mean is 2.7 Ohms, which is what the speakers are running at, they aren't a normal 4 ohm speaker.

crossover goes between the amp and the speakers BOTH speakers, Woofer and tweeter.

BAF can fix it.

Have you checked the polarity of the speakers? Having a reversed polarity can cause the popping (I assume you didn't mean pooping) sound you described.

I don't know anything about polarity. Would the fact that it's all running at 4 ohm and the speakers are 2.7 have to do with anything? The guys doing the install aren't total noobs. I'm just trying to figure out the reason why. Again, sounds fine on most songs. Tweeters are amazing. Woofers just get rowdy sometimes. Well I plan on getting to the bottom of it tomorrow so I'll keep you guys posted!
