I was kind of skeptical about this thing but I figured give it a shot. Hear me clearly, I will never have another sound system without one of these...EVER. Not only does it bring out the bass for older music but I can’t explain to you how it gives clear quality lows. I currently have 2 massive audio summo 10” subs in my car on skv.2 3500 amp. When I tell people that, they loose their mind and want me to pop the trunk to see for themselves. Now before I had this processor they were hitting hard but with the addition of this they sound amazing. I haven’t told the other guys in my neighborhood with systems... it’s my little secret.. I have it tucked away so no one ask what’s that... lol. Anyways if your on the fence about it, I highly recommend. Trust me you won’t regret it
