i ordered a single 10" (svc) and have it hooked up to an Mtx Thunder 502 (592 rms). This woofer is no joke, it handles my Mtx with no problem and it keeps begging for more! i have it in a 1 cu. ft sealed box and damn its amazing you would never believe this clean, crisp, deep and accurate bass was coming from a 10" THIS THING IS BAD ASS!!! Make sure to give it pleanty of power it wants and deserves it!!!
I have this in a custom made down-firing sealed box in my acces cab Tacoma behind my seat. I'm powering it with a Hifonics ZRX500.2 and this thing wants more than that amp can give. The xmax is no longer the 3 inches but 1 inch on the newer model. It still gives plenty of extension and sounds great filling the cab of my truck with bass and a bit of a massage. If you want to get loud then get a few of these and give them proper power. I'm planning on upgrading my amp soon to get more out of the sub.
