Yes, I will keep the fiberglass mold IN the spare at all times. The pictures just show the mold - i still have about 4 layers to fiberglass yet to make it the thickness i want. After i am done fiberglassing, I need to glue/glass an MDF wood cover on top of it and cut a hole for a subwoofer.
When i need to use my spare, I can just take the whole thing out. It is a complete stealth install - you can't see it's there and the spare is still operational.
The console is fairly easy to remove. I did it by just playing around, but noticed that the PDF to install XM radio in the civic outlines it as well.
XM Radio
As you can see by my trunk shot, i forgot to route the remote wire. So i have to take everything back apart and route the remote back up front. I am using a Navone LOC to grab the signal from the rear speakers, which then goes to a class D amp, puting out only 300 watts. I am using the stock headunit, but also bought a DX face plate and bracket incase i want to use a Pioneer DEH-M9400P that I have laying around. It's a great head unit!
My goal for this car was simple though - sound good and be completely stealth. Being only 'loud' isn't my thing.
