Stereo & Electronics - Hooking up sub amp and I have a ?

If I tap in for sound on the very rear speakers, do they run off the Monsoon amp or the head unit? If they run off the amp, can I just tap off the tweeters since I think they run off the head unit.

I would tap the 6.5"s in the back seat area.

Its smarter to do a deck with RCA outputs though IMO

Are you talking about the subs in the back seat area or the ones in the very back? If I tap into the subs, I will be picking up too high of an input level for the amp. I want to tap a speaker line that does not run through the Monsoon amp first.

Anyone?

the deck only controlls the tweets...amp does the rest. sorry.

K thanks
