So last night it was extremely cold here -33 anyway i got in my car today and my sub is not hitting at all i'm wondering if the cold air would affect the sub or amp or everything? or is it somehow blown?

Wen its super cold dnt turn your shit up at all. Turn the bass down and listen to it at a low volume. Let the coil(s) warm up, then do it up. I never turn it the bass up wen its cold or at nite

it was down when i got in this morning and i cranked the heat up and it was really warm in the car for a good half hour-45 min but the sub won't bulge, when i put my hand against it, its not moving at all. my capacitor turns on when i turn my sub on so i guess the kinda excuses the fact it may be a fuse, i really hope its not dead i can't afford a new one right now.

cranking up the heat inside the car will do nothing for the trunk. subs have moving parts and in extreme cold they have limited movement if any at all. there is always the chance that you damaged them by using them in weather that was too cold.

Temperature changes cause metals to shrink. If you have any low quality connections, they'll be vulnerable to breaking or disconnecting.

You best bet, is to trouble shoot at your amp. Take a voltmeter to it, first check that your remote signal is working properly.

make sure everything is getting power and signal right does the amp turn on ? rcas in check all plugs

Maybe u fried the fuck out of your coil. i had a sub seize up on me. so i cut the surround, cut the spider and pulled the cone out to see the the VC and it wasnt even wound anymore. But go wit everyone elses suggestions and troubleshoot the amp THEN fuck up the sub..

sooo my sub is now out and sitting in my basement but i did look at the amp turns out the fuse is blown in the amp... easy enough to fix it.

i might be doing this completely wrong but i tried just popping a new one in and boom blew before it was even in there

so i took off the rca's uselesss

so i took off the power and ground, put the fuse in and it stayed, put the ground on, then put thwe power on and it blew again

ishould the sub be back in and wired to the channel before i do this? or am i doing sumthing wrong?

you have a wiring issue. your power line is being grounded somewhere. retrace both your power and ground lines for their entire length. also check the remote line while you are at it. something is being pinched somewhere.

Just to clarify, are you talking about your inline fuse on your power wire, or the fuse located on the amp?

Yup definately sounds like a wiring issue

call them and explain the situation. a quality shop will stand behind their work. keep in mind that once they find the cause that it may be your fault somehow and you would be responsible for the replacement of parts needed, if any. then again it may not be and they may have ran a cable in a bad spot and then you should have no charge to replace.

Grounding the positive power wire wouldn't cause the amps internal fuse to blow. There the ground would either sap all of the voltage away, or if it was a small contact area, lower the voltage substantially.

But I agree, its some sort of wiring problem. As nineball said, better to try the shop than to waste your time trouble shooting.
