one thing about the MTx amps and subs.......DONT BUY THEM.....no matter what anybody says. any reveiws.....now about the battery draining, if you have a switch, do not forget to turn it off, with your remote it shuts off with your radio, now im not a fuckin rocket scientist with car audio, but i am a part of DeepViBRatIOns.....a illinois based sound team....after i fix up the car ill show you. What im running right now is a HART 12" square sub, pounds ass, powered by a Soundstorm 500w*2....and im runnin a 1 farad cap. As for the starter, i had a problem with mine, but you have a different car, and personally id keep an eye on the starter, mine had to be replaced, on my dads bronco the same thing happend, he had nothing extra, what happend is that his solenoid went i think, it fried wouldnt shut off. thats all i know really about the starter, any questions about a system go ahead and ask
