These speakers are some of the best 12" inch subs that I've ever owned! It gives you the bass that you're craving but with a clear quality of sound. Very nice balance. I currently have 2 1000x watt Rockford Fosgate Punch Amps, one to each sub and it sounds unbelievable. Thumbs up, no complaints!

These speakers are the best I have ever owned and wouldn't trade them for anything else. They were delivered on time and in good package.

I love this product it's very loud and attention grabbing it's just what I have been looking for in a set of subwoofers for my vehicle
