im not trying to run a power house. and im not trying to bump it that loud. the JL 12" W7 dont really need that great amount of powers. i ran a 12" JL W6 before on the same supplies im using on this teg and i had no problem. i had an 2 MTX amps and it was running just fine. i had the ground wire in the trunk where the spare tire was and it worked fine.
