Boss BG300

A must have

Pros: The Bass generator itself makes the subs sound incredibly more refined and tighter sound. The sub-sonic frequency pass makes it easy to control the ultra low rumble that might not be desired. The cross fader is the next best part of the product, allowing control of the bass generation and the sub-sonic frequency pass with two knobs, This makes it easy to turn subs down, up or off if wanted. It also looks bad ass.

Cons: Hooking up isnt hard just takes time, like 20 mins to cut wires and get it going, also running the crossfader cord to the front of the car takes extra time.

Would greatly recommend this product, it has many features within the bass processor itself. Its not a $200+ processor but its as nice as u can get with about 80$

sound quality

nice deep bass notes for music with no bass. works great with spanish latin music and 70's 80's music. down side is that it only sounds good on some songs like rock hip-hop rap. its easy to use but a lil bit hard to tune depending on what speaker and amp your running

Beast

Best epicenter for the price no dought I bought this about six months ago and use it every day.

Bad Ass

I would recommend this to get only if hooking it up with a eq,aftermarket head unit,also crossover. I have done it and with the generator has cleaned up the bass from highs and subs hit harder clean. But I like hard hitting and this does its job no dought. Without it hooked up is ok but you can tell a difference. Not hard to hook up and the bass knob is handy. Peace
