I have 1 18" Q being powered by a Sundown SAE-1000D, 1000 Watt amp. Right now I'm just using the stock battery, and I don't think that it has enough power, because I already killed one battery after only using it very little. I need to know if I should get a better alternator or just a better battery, and maybe a capacitor. I'm not sure what type of battery I should get either... I was looking into getting an Optima yellow top, but I'm not sure which one would fit best in my car. The system is in a 2004.5 model Volvo S40, and I didn't see any Volvo option on Optima's website or any of their dealers.
So, to shorten this up a bit I need to know:
-what battery to get, or if the first battery dieing was just some sort of freak accident that shouldn't happen again
-if i need a better alt.
