I have already replaced the fronts with 6 1/2" Sony Xplod's And wanted to replace the rears with 5 1/4" xplods. Then if the sound isn't what I wanted I will add a sub.
However...the front and rear speakers are 3-ways will that throw the "soundstage" off with a sub?

Sony has a 10'sub and a 222w amp I was looking at, not too expensive but nice enough for me and my budget. The sub is rated to 700w(max). I read that underpowering a speaker is rougher than over powering one. so will the 222w amp drive the 700w sub?

And whats the best way to hook up a sub/amp to the OEM headunit?


Thanks...carl
