Amp is installed.
can't help but notice the you used some cheap audio/video rca's (I see the yellow one hanging there), I would suggest getting better RCA's that are shielded and meant for use in car audio.
just a question, are your RCA's and power ran on the same side of the car? if so reroute the RCA's, as a general rule RCA's and power lines should be kept as far away from each other as practical and if they have to cross need to do so at as close to a 90 degree angle as possible to reduce interference in the system.
