Iv spent a month trying to figure out why the base was so muddy and weak, tuning every x over point and gain setting i could

Finally soldered a longer wire so I could move it to the rear corner with the speaker facing at opposite side of the car, presto tight crisp base that shakes my rear vision mirror

These subs are a great value and provide nice deep base that will let the neighbors know when you are coming or going.

Oh they will rumble if you hit them with a lower Hz, but what I like is a crisp base

Base is nice and deep!

Paired it up with a Atrend E10 sv B Box and works and sounds great!!

While you definitely "feel" a good kick drum, its not quite as punchy or clean as it should be

Loud as s***. Worth every penny

Put enough power through it, seal it properly on a thick mounting board in the right sized sealed enclosure, and this sub will shame many 12"s, even dual 12" setups
