Hey guys, I just wanted to give you some sound system heads up. I have worked in car audio and ben into it for years now and I have some great news for everyone who wants to GREATLY improve their SHO OEM system without changing their factory radio. JL Audio has finally come out with the amazing CleanSweep. This totally converts the factory radio's signal and spits it back out into the factory amplifier. It totally cleans all noise and changes the sound wavelengths and volume adjustments to optimum. Trust me, JL Audio dominates the car audio scene and this new product will kick a$$. It just came out and is a couple hundred. But for all those who demand High Fidelity audio with inputs for crystal clear mp3 players, etc. (my IPOD) this is it. CHECK IT OUT!!! It came out in May, I am still waiting to get mine through my dealership. Just wanted to help you all out. C-******
