Okay, Finally got the stereo in the Toyota truck and amp. But now I'm getting a lot of line noise. What's the deal?

When you say noise can you be more specific!

Yeah, it's a hum that goes up in pitch when I accellerate...

ok .........a good place to start is with the way you wired you RCA cables and whether or not you ran them next to or (parallel) to the power cable........the power cable sometimes carrys a frequency made by the alternator.........if you have your RCA cables next to your power wire sometimes they will pick the noise up and you will hear it in your speakers........it is as simple to fix as re-routing your RCA cable away from your power wire....... Hope this takes care of it .................Lee

Reddleman : you did ground the radio and amp to the same point right?

Ivanp2: if you have to cross any wires, do so at 90 degree angles to minimize noise. You can also try getting a better quality shielded RCA cable too - popping for the higher grade signal wires can often resolve simpler noise issues.
