I own a car audio shop, and that is why I recommend the Zapco.

It's a better sounding amplifier. Why wouldn't you want the better sounding amplifier?

The impedance rating of the W1 per JL's website is either 4 or 8, and the guy who owns it says it's 4.

When you replace the W1 with a better-sounding woofer, won't you be glad you got the better-sounding amp?
