I recently installed a full system in my car with 4 infinity ref 6 1/2's, 2 infin amps, and a kicker solo baric L5.

The solo baric blew on me, TWICE. i decided to get my cash back and go with a diff sub.

All i can say is WHOLY SH!T! My new sub pounds, and has the most amazing bass quality i have heard.

I got a 12inch Alpine-Type X... power rated at 1,000watts RMS and up to 3,000watts peak...DAMN!
