i saw a Blaupunkt product called the THA a "plug and play" amp that is supposed to be adapable to easily intergrate with factory systems. it comes in mono ,2,4,and 5 channel the 5 channel require additional power. it also has a built in AUX input so it SOUNDS like something TL people might be interested in it looks like it delivers 75 watts per channel but if im reading the part number correct the 5 channel version only gives 55 watts per channel. its supposed to be compact prices go from 250-500 from crutchedprices so im sure it can be found cheaper given the built in AUX input does this sound like something 04-06 people should consider?
