These subs are great

I recently bought two of these triple 8’s and they are amazing, the amount of bass you get from one sub is insane it will literally rattle your brain! I would personally recommend buying these subs with their package deal that comes with the amps and wires, it’s much cheaper that way. 10/10 would recommend these subs.

Eights slappin?

Pleasantly surprised by how deep and loud these eights are. I have them paired with a soundqubed 1200. Just got through the break in and tuned the amp up all the way... they take every bit of that 1200 rms. I listen to everything too. From underground hip hop to PANTERA, these things sound great.
