So we're putting in all his old (if you want to call it that) gear:
JVC Double Din Deck
Memphis 6.5" Component Speakers up Front
Arc Audio 3 channel XDi amp pushing the memphis speakers and now
(2) 10" kicker comp cr woofers
This build was differnet as I had to order a dash kit and HVAC unit from Japan....basically anything with JDM on it will be expensive. Reason being, the GT models have dual climate control HVAC systems that are built into the stock deck, so you cannot simply take it apart and put it back in....so a new dash piece, HVAC unit, custom wiring harness, and mirrored hazard switch were needed.
Install was straight forward, bass knob in top center compartment, amp under passenger seat, besides the sub, you can't tell anything was done...unless you looked at the deck.
