I got two of these and they are loud. Only 150 rms each and on a 400.2 pioneer amp, my neighbors can hear me coming down the street. They are loud but have terrible sound quality. If your looking for sound quality i would not recommend these.

They alright jus needs more rms power.

I bought these subs and put them in a badpass ported sub box with a fosgate amp powering them and to tell you the truth they put off a decent amount of bass for a new basshead. I would very much recomend you spend the first 2 weeks just breaking them in. you will get a much better outcome.

I have two of these wired up. To get good bass sound you have to turn amp settings down. Yes they'll slap, or pound or whatever these people are saying, but it will be distorted if they do. If your just looking to add a bass concept to a bass-less system, go ahead its worth it. If your looking to bump, go elsewhere.
