How many preouts do you have on the head unit?Originally posted by VA Beach WRX
I've installed all my new audio, but I am getting interference from the RCA's running from the amp under my seat to the amp in the trunk.
I have tried moving the RCA's so that they are as far away from the power wires as possible, (power down driver's side, RCA's down Passenger side) but the interference is still there.
What can I do????
Thanks in advance!
Are you using the outputs of the first amp to your second amp?
The first amp might be boosting the engine noise to the second amp.
1. Run your RCAs AWAY from all factory wires. Also stay away from the fuel pump.
2. Ground your head unit with the amps. (run a ground wire to the trunk.)
3. Make sure you have a very good ground. (strip the paint to bare metal so you'll have a better contact.)
4. If you're using the remote turn on wire that is on the RCAs...don't. Run a seperate wire away from your RCAs for the remote turn on.
Brand named RCAs aren't any better than generic cables. Unless you're going to compete with your system, I wouldn't spend the extra money on brand named cables.
I'm already running $35 Monster Cable RCA's... i would think that these would be sufficently shielded...
