Looking at your build inspired me to go to a reputable shop in Roseville for an estimate. My goal is to dial in the stock Pioneer for now to make it sound better. The three piece component set could be made better. In the future ill be replacing them with either Dynaudio or Focal. Anyway I'm keeping the stock stereo system(head & speakers) and purchasing everything from him. I like to keep everything in house & warrantied.
Dsp: DQ 61 $319
Amp: Arc XD1 1200X6 $800
10" drop down dvd entertainment system in the back for our daughter to watch movies on long trips. $400
Blue tooth audio $250
Sound proofing floor & fr door $475
Head phones $30
$1200(roughly) for install
Now this doesn't even come close to yours and I'm looking at another 3k just to improve it. Aya!
I'm officially depressed. Lol.
