ok, ive installed this before on a previous car, i just would like to know if there is any particular way people have done this in the mark viii. i just need to find a solid + i can tap into, and i should be good to go.

Where are you doing the install?

Should be pretty straightforward, I have a power inverter hardwired in my TBird's trunk... I just used my amp's power wire.

I've ran a power inverter in the trunk before also. It was made to fit a cig lighter. I just cut the cord, ran the + to the amp wire and grounded the -.
