You could go with a sams duracell, diehard platinum (sears), duralast platinum (autozone), or something similar as a nice underhood agm batt. If you feel like spending a lot of coin then you could just get with xs.
not sure if anyone else mentioned this, but along with running 1/0 wire to the amp, you should run 0/1 from your batt to your fuse box and alternatorone of the things about my car is the battery is in the back so running 0 to the amps is too easy.
