Ok hes running Rockford Fosgate Punch A2 500 watt amplifer powering two 10" Audiobahn D. Jones Edition subwoofers. we turned up the gain then we turned up the bass control to try and tune the volts to 31.6 which is the correct number to set the gain at for his setup and they were hitting good when we tuned them then he said on the way home they were hitting so hard the sound was distorted. and they just stoped working so he checked the fuse still fine and he opened the trunk and they smelt like they were burning. any ideas?

they were wired in a 2 ohm.. not sure series or parallel

well if they can handel 300 rms and that amp might be capable of pushing that to each of the subs wouldnt the be matching the rms? and the volts wernt even right they were suposto be set higher which means that sub wasn't at full capacity which means less power going to the sub no?

wow.. this question sounds remarkably similar to another I answered by a guy who said he owned an A2 500w amp and the same model subs. What a coincidence!
Not going to add anything. I think the answer has been given a couple of times well. you overdrove the subs, the coils fried. Audiobahn is crap. buy something better.

when you run an amplifier excessivly you can deplete the power supply, that causes the distortion he heard then the distorted signal at a high volume caused the speakers to blow. If the amp is 500w RMS and each speaker is 300W rms they were under powered by 100w also contributing to the distortion it dosent matter if it was series or parallel it was still 2ohms making the amp work at its max as well.So this wont happen again make sure he has thick gage power and ground (4AWG minimum) run a capacitor so you have reserve power (and so you wont damage the battery or alternator) then run the amp off of that try to keep the speakers RMS handeling even with the sub amp

What do you expect from 60 buck - 300w RMS subs. You drove too much power to them!
Were they wired in Parallel or Series?
edit: I dont know the specs of the amp and couldnt find any on the web. Here are some sites that have car audio basics. Hope that helps.

It's possible they got too hot inside of the truck. Yes, even speakers need good ventilation to keep cool, especially ones running big amounts of power through them. Or, it could be the vent hole for the speakers got blocked somehow and the pressure from the air being compressed and decompressed rapidly could have done the damage too.
