I have my system that came out of my old car, all the stuff is only a couple months old. I have a kenwood excelon deck, Two sets of Infinity Reference REF6010CS, that were ran to a Infinity amp. And two kicker l7 10's.


My big question is should i replace the stock speakers for the components? Also what the best way to install everything, just rewire the whole car?

 

You "old" components certainly sound like an upgrade from stock, so yes, install it all.

Yes, "best" way is to run new and better wire, if you don't want to tap into the stock speaker wiring. You'll have to run power and RCA cables anyway, might as well run new speaker wire too.
