Question, is it possible to connect rear speakers? The old Spring rear channel could be set open. Whit the new? The front speaker allready have a nice treble (high tones). Still the car would sound better with some low bass. I'm going to bypass the front speakers and redirect them to the rear spare tire trunk where i connect a Bose Acoustimass
oustimas 5series2 and come back to the front with wires. The bose fits in the rear spare tire trunk.
