i forgot to add... from what i understand the gains can only go up so far before clipping right? well how do i know what that point is without going beyond?

what you are supposed to do is match the gain level on the amp to the output from your RCA's put a volt meter on the rca's from the deck and play something, then set the gain on the amp to match that... you start turning it up from there and you risk doing what i did to my amp hahahaha

You are on the right track, however the ONLY way to know for sure if you are not cliping the amp is to use a oscilloscope, first you measure the voltage from your deck and find the point at which the wave form starts to clip, then leave your deck just below this point and raise the gain on your amp untill the same things happens and back down a little bit, just make sure your speakers can handle the power. Or just bring your car to a shop and have them set it.
