in the near future my car will have jl audio amps, speakers, sub, wiring, connections,....everything except the h/u......go w/ the jl clean sweep to use w/ factory h/u...or get the kenwood flip screen dvd/navigation package ive been looking @?....also will the slash series amps b ok with out equalizer or do i need2 purchase 1.....going 4 complete sq could care less how loud

 

It would be foolish to keep the factory HU...especially since it is the primary source of distortion in our factory systems.

 

absolutely get the kenwood, an EQ isnt necessary. Keeping the factory headunit cleansweep or not makes all the other upgrades like 50% as effective
