Car subwoofer for making a cabinet

I got 2 Kicker L7 15's and I was wondering if there's an amp that would power both or at least one of them. The speakers specs are...
Impedance (OHMS) 2 or 4 DVC
Max Rec Amplifier Power (WATTS PEAK/RMS)* 2000/1000
Sensitivity (dB 1w/1m) 89.4
Frequency Response (Hz) 18-100

Waste of time and effort for live sound, bass or PA. You are not the first to have this idea. :)

Do you **really** want your bass to sound like the subwoofer in a car installation? Think about it.:eyebrow:

it's not even that! my understanding is that it would only have that massive window-rattling bass inside a car, as opposed to out in the world like PA speakers have to do.

the enclosed space is what creates the "room gain" that those very inefficient (89.4dB?) car subs need.

It is not even that - car subs are usually "one-note wonders" that rely on a huge peak frequency to reach the desired output. Flatness is hardly a consideration.

that makes sense!

the window-rattling sound one endures as they roll by does seem to be just kinda one frequency over and over, regardless of the song playing.
