Anyone use either of these to intigrate a system to their factory HU. I have a new truck (2004 FX4) and want to keep the factory indash 6 disk cd player but want to install my Arsenal 10 CDT comp set and ppi amps. I just don't think that the factory bass treble is going to cut it for tuning though. Any thoughts (hopefully from others with a similar situation) thanx in advance
