My last setup in my blazer hit 151 spl with 1 15" kicker L7 in a slot port box with a Directed 1100D amp and Alpine deck runnin 800 watts...Wires were Stinger 4GA kit with Silver Bullet RCA's
I just recently put a setup in my CSVT and havnt tested it but i wasnt lookin for anything large this time. Put in a 12" MTX 7500 with the Sledge Hammer ported box with MTX 3401D amp. The rms of the amp and sub are matched perfect at 400 and it sounds perfect. Wires are Stinger 4GA kit with Stinger Dream RCA's. Head unit is an Alpine of course.
