Please tell me how I screwed up!!!!!

I spent the day installing my audio, and am running into some problems!
First, its an 08 access cab. Well, the amp willnot turn on. I checked the remote, and it is fine. I'm getting sound from my speakers, but not amplified sound....lol. Its a 4 channel amp, and I am running the front two channels to my components in the front. I haven't hooked up the rear two channels yet, which I am bridging to my sub. I can't find a correct ground. I tried the back seat bracket, but that didn't work. When I move the ground around to metal in the truck, the amp lights up, but it reads protection mode.
The other thing I'm running into is road noise from the right speaker?? I am runnning the rcas on the passenger side down the door sill. What do I need to look for to stop this?
Thanks a ton for any help!

A couple things to check...

Sand off the paint when you connect your ground.
Check that your remote is hooked up to ignition (12v power when the truck is on only)
Run your power wires on the opposite side from your rca wires
adjust the setting on your amp

 

Where is your amp power wire?

Do you have a fuse in the power wire?

So your remote turn on wire is working but you get no sound from the amp...i really don't know what could be wrong there so hopefully one of the sound guys wil be able to help.

Did you get a capacitor also for your system?

 

If you can't get rid of the noise, they sell inline noise filters that run in the rca's.
Protection mode is normally because the power lines to the amp are hooked up backwards, or there is no ground. Best bet is to run power and ground directly to and from the battery.

 

What he said

 

When you say you are getting sound do you mean music is playing or just noise?

 

The remote is hooked to the wiring harness, the blue/white wire (Kenwood stereo). When I touch the ground to metal, the amp actually lights up, but says protection. Maybe I will run it to my battery!
When you say ignition wire, its the blue one, right? I know the red wire is power as well

 

Someone correct me if I'm wrong but I thought on most amps if the remote wire is not attached correctly the amp won't even show going into protection. As if it is not even trying to turn on.

 

You are right- The remote wire is hooked up correctly!

 

Sounds like you may have a problem with the amp iteself. Have you tested it?

 

Ok i'm really confused here. Your getting sound out of the speakers but not amplified? Are you getting sound out of the speakers without the amp light turned on? Either turn ur amp gain up and it should get louder or you have something installed incorrectly. As far as the ground wire a sanded down seatbelt bolt always works great. Also not sure what kind of amp you have but sometimes when the protect light comes on the amp is fried. Not saying thats your problem but it could be.

 

You don't need to run the ground to the battery. A seat bolt, or seat belt bolt are good spots to ground, if not find some metal and sand the paint off and use a self tapper and a star washer. The RCA's need to run at least 18"s from the power wire and if you crossing any other power in the car you need to cross it at a 90 degree angle. As someone else said you can get in line filters that will help with the alternator whine, but that depends on what kind of signal wire you are using... You may need to upgrade that instead.

I would pull the amp out and bench test it. Hook up some 8 gauge from a battery charger and just jump the 12+ to the remote and ground the other side. If it goes into protection and there is no load on the amp it is 99% probably fried. Good luck.

 

I haven't tested the amp yet.... I think it may be the ground. I'm going to try the seatbelt bolt, and see if that works.
Thanks for the help!

 

I took it by an audio shop- They grounded the amp, did tests, and the F*&^%^& amp is fried! Damn Ebay

 

Bummer

 

That sucks man, sorry to hear that. Hope everything works out for you.

 

File a complaint with paypal if the auction was for a working amp.

 

Told ya. Sorry to hear about it though.

 

word of advice for next time. I wouldn't power my components and sub off the same amp.

 

I decided to just amp the woofer, and keep the comps stock off the head unit for now. The alternator noise is still there, but I'll figire that out.
Thanks to all~
