Hey there, hopefully you have time to help a brother out. I picked you after some careful reading on sound quality, etc. I've got an 08 TL-S, with nav of course. I was looking at using an alpine pxa h-800 with the controller to feed my amps. I need a signal from the factory radio ( first time I've ever considered using the factory radio because of sound quality ) My main reason is to keep the stock look, use the nav, with voice promts coming out of the center speaker. Will I need to increase the voltage coming from the HU? I'd like to get the best possible sound quality using the stock HU. Am I wasting my time trying to keep the stock look when the outcome will not be the sound quality that I know is attainable in a car?

What are you asking for your headrest?

Not really. I'll post some pics of everything when the whole build is done. Hopefully soon.

Do you have pics of your after market nave?
