So,
The dash/rear speakers are connected straight to the HU, but the door speakers are going through an amp in the trunk. Correct?
I could replace the dash and rear speakers by just changing hte actual speaker and leaving all existing wiring, but if i want to change the door speakers, i would have to do re-wiring to get them to be powered directly through the head unit?
Just trying to make sure i understand this
If that's the case i'd like to take it 1 step at a time, ie: Install the new head-unit, replace just the dash speakers for now i guess [maybe rear as well], see how that sounds and then if i'm not happy figure out how to change the door speakers by either getting a new amp or rewiring.
MTX thunder 35 - for the dash, any particular reason you picked these? i'm not really worried about money too much as far as the speakers go if i can install them myself. If you have any other suggestions I'd take a look

Thanks so much for all the help!
