The best thing about the RF system and ride command is the auto volume adjustment. For that reason alone I'm glad I went this way, but it does put out quality clear sound. Not quite enough low end for my taste but it is full, will possibly try to remedy that over the winter.
I have the stage 5 with the 12 inch sub. The first thing I did was to sound deaden the whole interior of the sub enclosure, sounds much better. I removed the 400 watt mono block amp from the sub box (filled the hole), added a rockford 1500 watt 5 channel amp. Then I bridged 4 of channels from the 5 channel amp for the highs into 2 and ran that to the front speakers. The 5th channel runs the sub. (I have a rockford DVC marine sub on its way to replace the 4 ohm SVC sub, should get more power out of the amp). I bridged the factory 4 channel 400 watt amp that ran the front and rear speakers, into 2 channels and ran that to the rear speakers. Then I added a JL audio twk88 and summed the high and low output from the ride command to get full range, into the twk88. This made it possible to really dial in my crossovers. I created a few different modes in the twk88 for different types of music and it sounds pretty damn good. I keep my ride command with the variable speed volume and steering wheel controls. I know its not for just anyone one to do, but its possible.
