Adding Amp To Nbs Factory Radio

[MotoMedic]

want to add my amp to NBS factory non-bose radio (not buying my new nav/dvd head unit for a few months)

 

wondering if anyone knows an easy plug-n-play way to add preamp outputs to factory wiring? have a 2-ch line output converter.. just really didn't want to hack up the factory wiring for something i'll only use for a few months.

 

 

 

also, anyone know where i can get a factory audio wiring diagram- so if i do have to cut into the harness, i'll know which wire's are the speaker wires..?

 

thanks!

check crutchfield.com There are units that you can get that will reduce the signal to a usable signal for an amp. I forget what they are called, but crutchfield should also have wiring diagrams for the audio stuff.

I just finished installing an amp in my NBS Extended Cab Silverado.

I Had to hack into a few wires but its not that bad.

-I removed the panel on the passenger side in front of the door and tapped into the yellow wire for a remote turn on.

-For the rear speaker wires all you have to do is remove the sil plates on both sides of the REAR. I removed the front sil plates and even though some of the wires match, they are not the same.

-left side yellow- brown+

-right side lt blue- dk blue+

 

The bass output on the stock stereo steadily goes down as volume goes up. My band-aid for this was to get a remote gain for my amp and run it to the front of the jumper seat. It sounds ok for now but it should sound better once I get the down firing sub box. I just have an old box sitting on the floor while I wait for the UPS guy to show up.

 

MTX and JL Audio both make signal processors to solve the declining bass problem but I'm not sure how I want to build my system right now so I just installed stuff I had laying around.

 

Hope this helps.
