The amp is shot on this old Infinity BU-120 sub. What's funny is that I found two 10uF capacitor covers blown up, but I can only locate one of their mounts on the circuit board. I thought about trying to replaced the blown caps, but since I can't locate the second location, I'm just going to let the amp slide (or try to find the Infinity parts phone number and order a replacement amp - if anyone has the number please let me know). So what should I do with this otherwise "in good shape" sub enclosure and driver? I'd try another plate amp, but there's a brace in the way of enlarging the plate amp hole, and I really don't want to do a lot to retrofit an amp in there. There's two 2" ports 8.5" long (I think, need to double width/length). I need to figure what the tune is for the box (BTW, they used plastic flared opening with dense paper for the actual ports (like inner paper towel rolls). Kinda cheesy, but most people would never see it. There's a slab of insulation used for the stuffing inside as well. I'm gussing internal volume is around 1 ft^3. Any ideas?
