OK this is kind of long but I have planet audio DVC 10" sub:
Power Handling (Peak) 350W
Power Handling (Contin.) 225W
Freq.Response 30Hz-2.5kHz
Efficiency (1 Watt/1 Meter) 90 dB
Impedance 4 Ohm

It is running of a planet audio amp:
Bridged Power (4 Ohms) * 300W X 1 and it keeps going into protection.

First amp played for 30 mins and went into protection. So we looked at the wiring and everything seemed fine. Then took it back and got another one and 30 mins later it did the same thing. Even if I take the speaker wire off it still stays in protection. First off how in the hell is this thing suppose to be wired up and we are thinking that I need a better amp kit (4 gauge). Running 8 gauge now.

the amp can not handle that sub bridged, it is a 2 ohm load if it is a dual 4, you will get either and 2 or 8ohm load for that sub. You need a single 8 or a dual 2ohm subs, or get a mono amp that is 2ohm stable.

If that amp is not a monoblock, Ty's right it ain't gonna handle that load bridged. What are the parameters on the amp? U might want to ask your local stereo shop for a 250W monoblock. Concept HAD one. I dunno if it is still available. It is 250W @ 2 ohms. Underrated too. It is quite clean.
