Hey How can you improve on this???? Any suggestions would be great Here we go! Head unit is the Pioneer 8000, I went with this unit because of the 5Volt RCA pre outs now thats 1volt higher then most radios. the front and back speakers are Polk Audio 5.25 Componet sets powered by a Rockford 360w 4channel, In the rear deck are Cerwin Vega 6X8 the radio is powering them :-P ( The use to be in the doors. In the Trunk are 2 Solo Barack Kickers 12" Powered by a Rockford 800w The car has a 15 farad Cap keeping all the power I need and 0 gague wire from the battery to the cap and it has 2 4gague outs on the cap to a distribution block where it splits the two 4 gague wires into a bunch of 8's The Rca cables are Rockford White Wolfs The car is completely covered In Dynomate extreme Two layers thick everywhere Bottom top sides of trunk, and every door. I havent been to a car audio SPL yet, but I live in Michigan and well we suck here!!!!!! I have 2 old 99 model Kicker VR's if anyones interested.
