Great system? Horrible sound?

[SubmerseMusic 10+ year member]

The installer made them sound correct, but, today I had them put foam baffles in the front speakers, 3 1/2 in the dash (which I ended up taking out because they sounded horrible), and re-run the ground of the head unit (with an aftermarket ground).

I played with the amp and got everything to sound good, but a minute later it sounded really thin, the bass is really boomy, and I can hear a bad hiss. There is no white noise when a song is not playing, but when it does, you can hear static. And when you turn up the volume knob you can hear a pop (distortion). Ground loop sounds likely.

But would the amp be looping or the head unit? And how would you fix that?

Check your grounds and make sure the crossover on ur headunit isn't opposite the crossover on ur amp

First Picture- Head Unit Ground

Second Third and Fifth Picture- RCA Headunit

Fourth Picture- Amp

Head Unit set to 60Hz

I noticed that the RCA's are acting funny when I pulled them off the amp. Could it be that the rca's are attached to different speakers at the head unit and the amp? Is it something that stupid? lol

I'm sure it has nothing to do with user error.

I'd put the amp on full, crank the bass boost and turn the volume all the way up. That'll show 'em...

These.

Hey. I have 6.5" Alpine type-r components in the front (crossover set at "6"), 6x9 alpine type-r speakers in the rear, and an Alpine CDA-117 headunit. The speakers are powered by a Rockford Fosgate P400,4. Simply put, it sounds like shize. It's distorted, hissy, and a sort of phase to it. The front speakers have baffles (so they are airtight sealed). The grounds are fine, I am running 1/0 gauge. I have NO IDEA what is wrong and neither do the alpine certified installers I took it to. Please help ) my ears hurt from the sound. I drive an 04 chyrsler sebring lx. Thanks

What kind of certified place was this?

 

[SubmerseMusic 10+ year member]

Alpine certified. Rockford Certified. Pioneer Certified. Kicker Certified. Stinger Certified.

But I guess that the installer may not be actually certified... hmm

 

[MikeyF 10+ year member]

I would HIGHLY doubt they are certified, if they can't find the problem. Sounds like an easy fix if you had everything in front of you, the "Certified" installer should have been able to fix this easily. Was it a local shop, best buy, etc?

It was a local shop. And I live in Montana so... they are the only "good" one.

This Friday I am supposed to be getting my whole trunk and two of my doors roadkilled. Plus put two 15's and an amp to be put in, and a yellowtop optima. BUt I don't want to keep putting crap in my car if it doesn't work.
