I just put in a new 10" subwoofer, and at semi loud volumes it pops then stops playing. I cant get it to play again till i turn my reciever off and then back on. Its annoying cause i cant even play it loud. My clarion reciever has a speaker protect circuit could that be it? or is my new sub Blown?

How do you have a 2 ohm dvc speaker wired at 2 ohms? Is the amp bridged? if it is then you need to wire the speaker in series not parallel. Maybe your running a 1 ohm load on the amp. That would sure do it.

i have each coil wired in parellel, negative to negative to negative, and vice versa, according to the rockford fosgate book, my amp is a mono amp so i cant bridge it, how is it possible to run a 1 ohm load??
 

yep

if you have that dvc 2 ohm sub ran parrallel then your amp is seeing a 1ohm .

this is your problem, the amp is only 2 ohm stable.

you will need either a dvc 4 ohm sub or an amp that is 1 ohm stable.

you may need to look at some better shielded RCA cables. Check Kuno-concepts.com

you can wire it in series and have 4 ohms and your amp will still put out 200 watts. otherwise you will need a 1 ohm stable amp or a 4 ohm dvc speaker in parallel

or get another speaker and wire both speakers in parallel and then series them to the amp. or series each speaker and parallel them to the amp. this would give you 2 ohms.

yep. there's one way: use two amps - one on each coil.

would running it in 1 ohm for a day or 2 hurt anything? would i blow my amp or sub? other than the speaker popping and cutting out thats the only symptom. would it hurt anything to use it till i can return it and get a 4 ohm dvc??

the sound you're hearing might be the amp's defense mechanism. many amps have protection circuitry to defend against things such as too much heat and/or too much current delivery.

i don't know your amp that well, so i am only making a guess as to what's going on. it could be something entirely different.

if it were me, i wouldn't run things like they are. obviously, you have a problem that should be fixed asap. try disconnecting the turn-on lead to the sub amp. that way, you can listen to the rest of the system while you get the sub problem fixed.
