w7 hit good without a jl amp?

What is the model # of the amp? -Or, more specifically; what size fuse(s) are in the amp, and what class is it?

Also, the enclosure plays a bigger role than brute power. What enclosure do you have it in?

I would think the amp puts out close to 800-900watts, not too bad. California Profile amps aren't of the highest (or even higher) quality, but they are still great for the money -from what i've seen.

The AP2000 is a pretty powerful amp - strictly power-wise it would do a decent job on the 13w7.

The problem is the sub is a dual 1.5 so at most you can only get a 3 ohm load on the amp.  When bridged the Profile can safely drive a minimum of 4 ohms.  Being a budget amp it probably wouldn't end well if you try to drive 3 ohms with it.

If you don't get the JL amp, or something similar that will give you around 1000w at 3 ohms you're looking for a mono amp that does 1200-1500w at 2 ohms.
