I have a JVC CS-GD4300 12" subwoofer connected to a 130 watt amp. This was my first subwoofer so I have no frame of reference as how good the combo is. heres a lik to the sub http://www.crutchfield.com/S-q2eNTs...p?search=CS-GD4300+12"+subwoofer&i=105CSDG430 I recently purchases two Infinity Kappa Perfect 10.1's http://www.crutchfield.com/S-q2eNTs....asp?I=108per101&search=infinity+perfect+10.1 with a Kenwood KAC-9102D amp http://www.crutchfield.com/S-q2eNTsjMRFb/cgi-bin/ProdView.asp?g=120&I=113KAC9102 that is currently being shipped to me. How do you think my new system would compare? I recently connected my amplifier to the a distibition block with a 4 gauge input because my new amp requires 4 gauge wire and ground wires. Since my amp has not yet arrived the only amp hooked ti the block is my 130 watt amp. Recenlty it has been overhaeting and cutting itself off after no more than 30 minutes of use. could the 4 gauge power cable going through the block to the 10 gauge wire of the amp be causeing this?
