Made some little jumpers to go from the factory wiring to the new sub. This makes it easier to install because it makes the wires longer, but mostly I did it so that i didn't hack the factory wiring and can return to stock.
Here is the jumpers taped up and the factory enclosure filled with poly-fill.
You will have to use a pair of dykes or a file to knock off this tab above my finger, it's the alignment pin for the factory subwoofer.
great write up and mods. Random question, if you're still hanging out here. I just added the HK sub to my system (had already done a full HK speaker swap but never the sub as I have 2 x 15" MTX's), but wanted to add the HK sub for when I haul stuff and take my box out.
Hooked it right up to my amp for the MTX's, works fine, using the Black and Red connectors, but what are the other 2 for? To wire it in stereo? I see you connected all 4 to your quartz.

you’re running two 15” subs off the stock Harmon Karden amp? Is that amp powerful enough for that? Must have a LOT of bass.
4 week old still brand new bought it now I wanna sell it I’m like that I buy stuff that I want than I just end up selling it brand new custom carbon fiber with. Leather sides trim carbon fiber red stitching and red strip $2000 OBO. eBay selling it $2600
How did the subwoofer swap sound? Is it really an improvement? For my E550 I hard wire tapped directly into the low level input to the HK amp and ran a separate self-contained 10" sub/amp. I loved it for 5 years, only running about 1/3 gain to balance with the rest of the HK system, but this may be a simpler path. If I opt to go with a separate sub again I'll probably try one of these new units that sits within the spare tire.
