Really good Amplifier

I installed the amp in my ford truck and i immediately experienced a significant improvement in the depth and power of the bass.

Worked Great!

Spent some time trying to find the OEM replacement for my Suburban's subwoofer, only to confirm that it has been discontinued.

This speaker fit perfectly and sounds as good, maybe better than my original at a fraction of the price.

My stereo sound is back to normal with full bass.

MB Quart - If you haven't heard of it, you should!

Deep, heart pounding bass out of a little 8" sub? That's what the MB Quart RLP204 delivers. Used it to replace a factory sub in my GMC Yukon XL and it blows it away even with the stock radio.

Good product

Looks good and sounds good. But don't expect big punch. These really are only designerd for small enslosures and tigh spots in little cars. They are a good compromise.

Surprisingly good!!!!

I bought this sub next expecting much from an 8", but after I paired with Rockford Fosgate Prime R250X1 and it was surprising! The lows sound great and it's enough for me to pump up when I want to ride and enough to turn down when the kids are in the vehicle. Great sub for the money!
