Starting to work on my DD. System plan is:
Source - OEM head unit, convert signal to digital plus a mobile phone to have digital out with pdt on factory display and steering wheel controls.
Front speakers- Bliesma T34B and Purifi PTT6.5X04.
Sub- Hybrid U12SW
Amp / processor- Harmony 8x12DL
May switch source if i find a unit I like with toslink out. Space is important so sub is in spare tire well snd amp under pass seat.
Tweeters are playing to pick location along with old focal K2P in the door since Purifi won't like that location. Will also be fitting a larger 135A mitsu alternator once i can fab new brackets.
I think that covers current system details, we'll see how much that changes as things progress.
