Hi, can someone help me. I need a new battery as I suspect my system killed my (standard) one. I want a deep cycle one so it withstands my set up but I can't afford too much.

I am running:
CarPC (see sig for details)
1600w Mono amp
800w Stereo amp
A few cold cathode lights
Undercar LED kit

Not that much really so would this do the job?
