I recently upgraded my OEM JBL Navigation with a Pioneer X930BT and I have to say I really like this unit. I had to by-pass the factory amp but that's ok. I'm replacing the front speakers with some Pioneer TS-A1604C and Polk DB651 for the rear. I'm not looking to blow the windows out of the truck. Just want better sound. I went to Best Buy and one of the auto stereo installers said this would be a good amp for the speakers and it doesn't take up a lot of room. I'm writing to see if anyone has ever used it or heard anything about it.

Thanks

The KTP-445 Power Pack won't work in systems where an outboard factory amplifier is still active. You'll have to bypass the factory amp if you want to upgrade your power with the KTP-445.
