Audio Control Epicenter Indash Bass Restoration Processor
I don't usually do ratings, but this item made me take the time yo do so...it is worth every penny. The convenience of having the controls right at your arms reach vs having the standard in the boot type bass processor is much better.you only need half the gain on your amplifier when using this.the quality of the low bass is shattering and the ease of just pressing a single button on it to return  to normal bass when the bass is getting to you  makes this item 5 star for me.
