i installed an amp on my friends tacoma..and when i started the car it made this weird buzzing noise..it stops when i unplug the rca cables..i have installed plenty of amps before but this never happened..

heres what i installed:
cheesy (swap meet) 4 channel amp, 2 jl audio 12s

heres how i installed it:
i put the amp under the driver seat
i ran the power cord on the driver side
rca cables down the center console
ground cable on the seat bolt (whatever)

i used an amp wire kit so i guess wires are good.
im not into sounds but its fun

 

is the amp only running the subs? Is there a low pass filter on the amp?

 

the two subs and two front speakers..

 

the amp is running the two subs and two front speakers.

 

Run a ground to ground the head unit to the SAME spot as the amp, close to the amp. This noise is usually caused by ground loops.

 

i just did that..sound didnt go away..i figured out the problem..its the amp cause i put my amp in his truck and there was no buzzing noise at all..i told him to return it..

THANKS SP for all your help!
