This product is a vintage MTX Road Thunder Pro subwoofer with an 8" speaker size and dual voice coil. It has a RMS power of 400w and was manufactured in the United States. The model is TP828 and it is a DVC (dual voice coil) subwoofer.

MTX Audio USA Throwback 90s subwoofer  The sound is amazing. I had 2  jlaudio subs in a box  8w7 made

To replace these because of all the hype online well it sounded more aggressive but only on a  few songs  these mtx require less power and gives more bass on every song without bass loss.

Dual 4 ohms subwoofer can be wired up to 2 ohms or 8 ohms

And even 1 ohms using both subwoofers
