Thought I'd do a bit more on my install today, so here's some pics!
Seat backs unzipped, mdf panel slightly larger than amp. Marked out to show where metal frame of seat back is.

Holes for cable ties and wire exit points drilled, and mounting board secured to seat back.

Holes big enough so that cable tie does not protrude.

Wiring all in place and cover re-zipped. Sub cable is the thicker one to the left, the front speaker wire in the middle and rca's to the right. These will obviously run to the front of the car and won't be visible!

Amp fixed to seat back and wires terminated and attached to amp.

Close up of connections.

Sub cable cut to length, braided, routed and quick release connector fitted. This will allow quick removal of sub in case of track days or boot space requirements!

This shows it plugged in to back of sub. This is looking from the back seat into the boot. I am going to make a quick release bracket that fixes the sub box to that metal ridge at the back of the boot.

And this is it all in place. The DLS 10" sub and box is very compact and light so is perfect for this application imo

Next jobs are to run the wiring forward, fit the mids, fabricate tweeter mounts, fit sound deadening etc etc! Still.... 1 step closer eh?!
