Purchased this subwoofer couple of days ago from autobarn. Its Dual Voice Coil (DVC) 2 ohm per coil. I wired it in parallel to give me a 1 ohm load. the amp im running, runs at 1 ohm which produces 900RMS to that subwoofer. to get any real bass the Gain etc are tured up, at the most a 3/4 turn. When you get a deep bass song, and past a certain volume, which isnt that loud to me, the subwoofer makes a crack noise as if it is clipping or something. when all gains etc turned right down its not a problem but then its not delivering enough bass to my taste. i have now rewired it to a 4 ohm load, the sub is recieving 500RMS. Gain etc has been turned up to my taste, can have it as loud as i want and no crack/clip noise. so im wondering if the product could be faulty? it states on the instruction manual that it can handle either 1 or 4 ohm load. Have had it back to autobarn as i was a bit disappointed with it and they couldnt fault anything to do with wiring etc. No burn smells, just a crack/clip when the volume passes a certain point. Is there a trick to wiring DVC's in parallel (++ to -- to Amp). Also the sub is 1200w peak and 400rms. shouldnt be over powered realistically as different frequencies will change your load value ranging from below 1ohm to around 3-4ohms. Im no pro so someone with a professional background would be appreciated. Hope you can help me out, ppl. Cheers!
 
You were severley overpowering the sub. That's why they have a rating in the first place. You also don't say what kind of enclosure you have which is very important.

Also look to the sensitivity of the sub, a sub with a 92dB sensitivity or higher is recommended.

The purpose of the gain is to match the signal volts RMS coming from the source (CD player, etc.) to the input of the amp to prevent clipping (damage by over powering).

Here is a guide that will help you set the gain correctly http://www.box.net/shared/uchv4dbk88

You'll need a multi-meter (AC voltmeter, $15 from Radio$hack), Microsoft Excel and a way to burn an audio CD from an MP3.

If you don't have Excel, use this link http://www.box.net/shared/nkkw1dhk4g

connect one voice coils + to the others + and the negatives the same way. then come out with a single + and a single - to the amp. make sure your amp is wired with 4 AWG wire on the positive and ground. also make sure you are using a 10-12 AWG speaker wire. use the amps built in crossover if it isn't defeatable.
