I have read most of the posts concerning car stereo at this site and have yet to realize the answer to this particular query.

I am in process of removing Bose from 3rd gen touring coupe and replacing.

Having just completed the in door mounting for some MB Quart speakers woofer and tweeter requiring a two pair feed from the crossovers I am in a quandary as to how to proceed.

The existing 4 wires for the Bose are a 12 volt common feed from a relay and audio.
There is no way to feed another wire through the flex coupling between the door and dash interior because of a big Molex type plug blocking the entrance to the under dash from the car door.

A local shop said they could drill a new hole and mount a loom, this seems a bit drastic.

I am not aware of the place where the power to the Bose unit terminates as I may be able to use that for a tweeter feed.

Any suggestions would be much appreciated and if the answer is somewhere on this site and I missed it then kindly point me in that direction.

Thanks,
Mick

Mount crossover under door panel. Seen it done before.

The crossover would be the easiest solution yet it is too big for me to find a suitable place in the door, seems the MFG could have made it smaller...

I shall look at getting around that plug.

Thank you for the good suggestions!

hey if your close to portland let me know if you need anything car stereo related, I would love to help out a fellow rx7 owner.

Thanks FNP for the offer I am way down near Ashland so a bit far, would be kinda cool because I have only seen one other 3rd gen in the area, not too many down here.

I seem to have found a place to mount the crossover, although there is no room in the door panel left there is room in the door that does clear the glass.

I could mount it on the outside of the door panel but then slamming the door might cause an indentation dent, the other interesting solution is on the bottom at an angle so the terminal screws are just protruding a bit into the door panel space.
The crossovers will have to be bagged or something in the odd chance the car is outside in the rain, but not planning on running gobs of power so the cooling hopefully will not be of issue.
The bottom of the door is concave and so will require a flat mounting plate of plexiglass somehow adhered to the bottom and the space filled with something between plate and door and the crossover mounted on top of the plate. Not sure If one should use gobs of silicone and just fill the opening and slap the plate over then let it dry or some kind of expanding foam or what.

Any suggestions are welcome.

thanks again,
Mick

You could use the power wires for your 2nd pair of audio if you cut the wires inside of the car.

Good point, that was my next step if I couldn't find a way to fit the crossovers inside. I may end up doing just that if this concept doesn't work for some reason but it is kind of nice having a stock harness that has not been compromised too much. The wires are all wrapped together so will need to be unwrapped then identified and sliced, then again one would neeed to find a mounting place for these crossovers, but up where those wires exit may not be a bad spot...
