So I've been looking into replacing the Bose subwoofer that sits in the wheel of my Mazda6s hatchback. This sub is powered (unlike the standard saloon) and the connector has 5 wires.
Anyway, I started looking into the wiring, hoping to glean some information on how things are connected. I found a couple of interesting things.
1) Even though there are 5 wires going into the sub connector, only 4 made their way to the sub unit itself. The Black/Orange wire is pulled from the loom and just taped to the side. It's not connected to anything - also verified with a continuity check.
2) The Sub enclosure itself is easy to open and it reveals a small speaker (something like 5 inches) plus the sub amp. The chips used in the amp are obviously custom-made for Bose and you can't get much information from the board itself other than...
3) ...The PCB is labelled with the functions of the cables, but this is obscured with the connector.
Has anyone else worked out the function of the 5/4 wires going into the powered sub? If so, I'd rather use that information than re-invent the wheel. Otherwise I'll desolder the connector from the board and find out, and post here (obviously).
I'm planning to replace the existing sub with an Infinity Basslink unit (powered). This will require a new power connection from the battery since it's electrically more demanding than the Bose unit.
