JL Cleansweep or Rockford 3Sixty2?
 

Because I want to have the best quality possible without changing my factory radio, I was told I needed a device like this between my factory radio and my amp. I know there is quite a difference in price between the two.

Is anyone here familiar with JL Cleansweep or Rockford 3Sixty2?

Does the high percent difference of price of Rockford 3Sixty2 over the JL Cleansweep is justified by a similar percent in better performance?

Should I be looking at another device similar to these two that would give me a better bang for my money or better overall performance over the Rockford 3Sixty2 or the JL Cleansweep?

Thanks

Alex
