another quick question.... I got a Eclipse Titanium 12" Sub (sw9122) i think - I was told that i need 2x 1507 to run it as its a moster of a sub.... is this true or will 1 do? im not after the loudest system but want good sound. then i go back to my first question, if i got only 3 amps then will the capp do or do you think i will still need a second battery.

Thanks for your help
