The only way to connect the Delphi equipment, is through Fm modulation. You can use the hard wire or the wireless, but that is the only two ways. Now, hardwiring it isn't hard and it delivers pretty good sound too. It is better than FM ,but not quite CD.

I think it looks great! It is a nice simple install, but I'm sure it gives pretty good sound.Facing the box up, is a nice little trick to make subs sound bigger than they actually are.

Hi,One thing to remeber is that peak power means nothing when matching and amplifier with speakers.Only pay attention to the RMS, that is what will decide of you will harm your speakers or your amp. 50x4 is a good choice for cab speakers!http://www.crutchfield.com

Satelite radio is near CD quality! I'm using an FM modulated Pioneer with my Alpine head unit. No one can tell when I switch between CD and XM. With a direct connected tuner, it can only be better!If you go FM modulated, the signal is compressed somewhat, but it isn't that noticeable. Direct connect...
