I spent all last night removing my amp, and sub from my system. I have a pioneer deh-4100 and 4 speakers (US Acoustics). First off, my engine was overheating with the sub hooked up. Strange...

I hooked the sub up, engine overheats. I take it off, no over heat. I did this about ten times for a couple of days. Wierd. I'll never buy a pep boys battery again. It looks like an optima will have top be shoved in there. The amp is useless with out the sub. The speakers sound better by them selves without the amp. Anyway, I took it all out. Man, I can't wait to get another battery. This absolutely SUCKS! I am so use to "brain stem loosening" bass and soul crushing midrange/highs, that the receviers power is not even worth listening to unless your not moving. I swear, it sounds great in the garage. But once you get up to speed on the road with the windows down, and sunroof open, you can't hear SH*T! I have some questions.

#1 Can everyone post what they got? So we can see who has what gear and what they think of it. Maybe even plans for more upgrades and so on. What type of music, etc.

#2 What batteries do your guys use? Anyone who upgraded? If so, what battery did you upgrade to? How much CCA, Amperage rating?

Thanks for any response.
