So my subwoofer driver blew up and 2 months later my sub amp is leaking capacitor fluid, I don't have another amp to use so I ended up rigging this awesome setup.
A Pioneer Wal-Mart 100watt amp hooked up to a 4amp DC power supply, and a Cerwin-Vega super old-school el cheapo. The amp cuts out when the power supply overloads, so I get about 40 watts to the sub.
Doesn't even get loud enough to feel air coming out of the ports :(
