[Begin Part 1]This question has come up over the years and in wanting the addition to my 2004 wagon I decided to figure it out. For anyone who is interested the addition was well worth it. I do now have to tighten my rear-view mirror because the factory Bose sub-woofer shakes the thing like crazy making cars an utter blur behind me.
What is needed:
- Factory Bose powered sub-woofer.Wagon and hatch have a spare tire mounted 100W, 0.5 Ω, 5.25 in Sub-Woofer.
- Factory short-cord(4M81-13A576-BB) that attaches to the sub-woofer and vehicle installed wiring behind the left rear interior panel.
- Line Out Converter (LOC).I used the Kicker KISLOC2 because it had potentiometers to adjust gain (very important to get balance correct)
- Factory Wiring Connector to scavenge wire and pin combos for plugging into factory wiring. (not necessary if splicing)
- Some 18GA and 14GA wire, plus solder, heat shrink tubing and electrical tape.
I have a May/2004 Mazda 6s wagon. This vehicle stereo required an L701 jumper to integrate with aftermarket components but otherwise is normal for the vintage.
The Bose parts missing are:
- Wire loom (4M81-13A576-BB) from the left rear to the sub.
- Wire loom from stereo (to passenger foot-well) to Bose amp (under seat)
- Bose amp (under seat)
- Bose head-unit
- Bose sub-woofer
