Has anyone tried the JL Audio Clean Sweep? Does it work well with the factory radio or are there any issues with it?

 

You can use it. You don't need to signal sum on this car. The pre-amp signals are full range for the front and rear.

 

im thinking of doing the same is there anything else i need to get to use the clean sweep?

 

amp and new speakers

 

I assume this would hold true for a 3sixty.2 as well?

I was wondering if I should sum the signals.

 

You do not not need to sum the front, rear and subwoofer channel to get a full range signal with the TL radio. The signal summers were created for cars (and there are many) where no single signal is full range.

If you want to processes the signal, then get a 3sixty, JBL MS8 or an Audison bitone.1. If you just want to use some components on crossovers, then the low level input on your amp, or a LOC with RCAs, will work just fine and sound a million times better than stock. If you want 2 million times better, then buy a processor.
