Can i hook up 6x9s and 6 1/2 components to the same amp?

Question

how do other people hook up their speakers in the rear deck and in the doors

Answer 1

yes. Hook up your 6 x 9's and your components to one amp and use a seperate amp for your sub or subs. Keep in mind the amp needs to have enough wattage to run the speakers, but one amp is sufficient for those speakers.

Answer 2

yep- that's what 4 channel amps are for.  If you only have a 2 channel amp and are not in a position to upgrade, hook the amp into the 6x9s and run the splits of your deck so you still have front/rear fader control.
