Its an '03 civic, the amp is a JL audio 500/1. the reason i said that,
was
because i left my stereo on while pumping gas once (for about a minute no
longer than that) and two days later my deck started dimming because it
wasnt getting enough power. The battery died, and i jumped it, since then
no such problems. I guess i should just replace that battery then. (like
I
said im a bit of a noob with car audio, so i just made assumptions as far
as
the whole battery situation)

I would HIGHLY recommend buying an Optima Yellow top battery. I remember
the first time I used an Optima battery (9 years ago) and it made a big
noticeable difference in my stereo. It has really low internal resistance
so when the engine is running it saps less of your power (when the engine is
running, your battery becomes a load to your electrical system, this is also
why you don't want two batteries). The other great thing about a Yellow top
is that it can be drained and charged over and over with no degrading
effects. They're expensive for batteries, but IMHO, I consider this the
MOST IMPORTANT electrical accessory in my system (more important than my
caps).
