after successfully completing setting up my basic ICE(hurrah,round of applause as I marvel at my limited skills etc) -I am now left with standard shitters up front, kenwood 7x10s in the rear, and an amp with all the wiring siting there doing nothin.What should I amplify?-it cannot drive subs but is 4 channel x a mahoosive 40watts.Any ideas?- or should I get rid and not have any amps etc?
