so my friend bought a crappy 200 watt walmart amp and a wiring kit. with speakers hooked to it, when the radio is on the speakers stay at the same volume independent of the head unit volume, example: the speakers hooked to the amp are the same volume regardless of head unit volume 0 or 30

Sounds to me like the input to the amp is connected to a constant-level output from the HU. ------------- Support the12volt.com

Wal Mart or no, what brands and models are being used in the signal path here? Deck, amps, anything in between would be useful info.

its a pioneer head unit, not sure what model, an older one green backlit and plays dvds, (if that helps?) and then a walmart "VR 200 watt amp"

scratch that.. noticed that you said the deck had a set of pre-outs, meaning it's aftermarket. don't know what to tell you there. one idea would be to try it with a different source.. leave the car on (so the amp stays on) and plug in a portable player using a mini-to-rca cable. if the amp's volume changes with the portable player, then the problem lies in the deck somewhere.. if the volume stays constant again, exchange the amp.

yeah, i keep an old md player and mini cable in my toolbox for just this sort of weird situation. a seperate source helps out sometimes. (that and i have nothing else to do with my mini-discs.. the only things that even use them are both in my toolbox.. the portable i use for testing, and the deck which is installed in one of the drawers of my box)

My friend bought one of those amps (against my advice) and I helped him wire it up. Although it didn't sound very good, it's volume worked with the HU.
