Hey guys, my MRD M1005 amp has been throwing the "CUR" code, overcurrent, and all my wiring is fine. Pulled the sub out of the box, and it smells like burnt voice coil. Its a SWR-1242D, Type-R 4+4 12 inch.

could be the coil. get a multimeter, and check.
normally burnt coils are caused by an underpowerd amp, or possibly a very overpowered one.

After testing with my $9 dick smith multimeter, one voice coil is returning almost perfectly 4ohms, the other 1ohm. Time for a new sub.

Its a 1000WRMS amp, the sub is good for around 50WRMS, but I wasnt running the gains very high, less than 3/4.

EDIT: 500WRMS....

You can cook a sub with an underpowered amp or an overpowered amp, clipping is a bitch.

Yeah the amp certainly wasn't running at a level that would cause clipping, you only make a noob mistake like that once, let me tell you.

hehehe... you say that but I have seen someone cook 5 consecutive PAIRS of subs from clipping :P

i had a alpine type S sub that had a failed coil.
took it back and they gave me a new one,
after they saw the amp i was running to make sure it wasnt my fault

Now that is a very rare occurance. Coil failure pretty much always get user blame.

i only had the sub for like a month or 2. and it just died. the coil like disconnected or somthing, so it wasnt burnt, it had duel coils and one of them just suddenly developed an open circuit.
they checked the sub, then saw my amp and gave me a brand new sub (newer model that what i had) on the spot.
too bad that the shop doesnt exist anymore :( great customer service
