Also, how do you only have one box, but are able to boost the signal for both the upper and lower parts of the window? This doesn't make sense to me.
Its a home build kit, you get them from a place called maplin here in the UK, however do a search on google and I'm sure you will find them.

There are 2 parts to the rear window, one used by the factory amp that I have left in place and the other connected to the new amp. Giving 2 feeds, one for Radio and one for the TMC.
