But of course electrical comes into play like kickin said.

I'm powering my DC Level 4 with a Planet Audio BB2400.1. It cost me 300 dollars and sounds pretty good. It puts out way more than rated power too. Get the 2 ohm dvc and you can wire it up to 4 ohms. There are smaller models of the amp, but it will work great when you go to upgrade your subs. And it sounds awesome on the lows, it controls the sub really well.

Congrats bro! Awesome job!

Yeah dude. Don't go lower than 2 ohms. Besides, you'll start raising the THD so sound quality will be less for no reason

Casemods - Yeah you can. You just can't run a sub with a lower impedence than the amp can handle. So you can't run a sub at 1 ohm into a 2 ohm stable amp.

It should be fine. If you can, get an oscilloscope to tune the amp. If you smell something burning, and it doesn't smell pleasant, its your sub burning.

There is more control and less distortion at a higher impedence. If you are louder at a lower frequency, its probably because of the stiff spider. Also if you have tuned your amp lower, that could cause it. I say you should press your hand firmly on the sub. See how far it moves in and play a song that hits low. Start off with the gain low, and slowly increase the gain and lower the subsonic filter. You want it to move a little past where you pushed it with your hand. Then raise the gain and lower the subsonic filter throughout the day. In a matter of a couple days, you'll be good to go

And for the amp, check out a crescendo if your budget minded. Or you could always get a head unit that has a high pass filter

Try metering your speakers first. Always start easy. Set the meter to the ohm selection. If the reading fluctuates quite a bit, as in by a few ohms, your voice coils are dead. Now its going to fluctuate for a few seconds at first. But if it stays steady, the head unit has to come out

And chances are if your speakers were messed up, it wouldn't have happened at the same time. Do you have a multimeter?

I agree. It sounds like a bad head unit ground. Try taking some wire (of equal or greater thickness) from the black wire on your head unit wiring harness, and screwing it down to the bare metal on your dash, if the sound clears up, it was a bad ground. Just a start

And remember. Cold subs hate lows even more. Lol

The only problem with the cold is cracked dust caps, but as AMI said, heat is the real enemy. I have had head units that mess up in cold temperatures, not sure why, but usually all I needed to do was take the faceplate off and put it back on, problem solved

Blasting cold speakers can be bad especially if they are plastic. I have had head units that mess up while its cold. It could be that
