OK - My turn. I've spent my time lurking, learning, and the odd technical post here and there whenever I could help out.
We just got our 2014 Highlander about a month ago.
The conditions, partly imposed by be, partly by SWMBO:
- Must be as transparent, physically and operationally, as possible. I've planned this down to having everything hidden, without taking up standard storage space, and with only the sub taking up any new space (and that taking up a rear corner and ending up flush to the wheel well, etc.)
- Car must remain usable pretty much every day through the process. This will mean 1 section / door / side at a time.
I had narrowed my equipment list to a short list. Once I had the car and tore into it a bit looking for space, here's what I'm working with:
HU - Stock unit
DSP - Helix
Amps - JL 600/6 and 600/1
Front MB (Doors) - SEAS W18NX001
Front Tweet (Dash) - SEAS 27TBFC/G
Rear Doors - JBL P662 Coax's
Sub - Image Dynamics IDQ10V.4
Damping - 60x SDS Tiles + Some butyl rope
Barrier - Barymat BM1A
Other - Prestigious Society NAVI enhancement to let me do Navigation and other stuff while moving.
- Trailer wiring and additional 12V outlet at the rear. Unfortunately no room for a power inverter since I would want true sine wave.
Note, partly to remind myself:
I intend to take measurements of the stock stereo 'as-is', as well as to get the curve of the electrical output (ie. minus speakers) to see just how much EQ is actually being done at the HU.
