Hi, I'm looking to upgrade the sound system in my 2002 GMC Envoy. A sales guy told me about the JL CleanSweep signal processor. This allows me to keep the factory HU which solves a few issues. I can then do a normal install with amp and speakers off the processor.

Anyway, has anyone heard of this thing and about how well it works?

Thanks

It is one of a couple of devices that you can use, I prefer the Audio Control interface devices personally. Take a look at them on their site. www.audiocontrol.com. I feel that they deliver much better value for the $.

 

while JL makes 3 clean sweeps,so we have to know what your looking for
