Car Battery?

I have been using an AutoCraft Titanium Battery from AAP for the past few years and have had to get it replaced twice in 3 years (for free of course). Looks like the battery can't handle the load from my vehicle. I have the carputer running in the back which doesn't draw more than about 70-80W max (all connected through the CNX-P2140), and a 700W RMS amp for my sub and speakers (which I don't really drive too hard). But inevitably, this ends up ruining my battery after about a year and a a half. What are some other good battery options. I looked at the Optima Yellow Top, but it costs close to 200 and only comes with 12mo. replacement warranty. Are there any other brands? Also I considered a capacitor but I'm not driving any crazy subwoofer setup (my amp only provides 150W RMS to the sub), so I didn't think a cap would solve my problem. Are there any other problem areas I should be looking for?

Have you checked the alternator and voltage regulator?

Auto parts store will generally do this for free. It might be your car that is damaging the battery.
