Voltage problems

Volfenhag 12' 1000w max 500w rms subwoofer

Audiobahn A8002T amp

Mobile Authority 1 farad cap

4 gauge wiring

Hey guys,

I used to have two Volfenhag subs and my voltage would always drop from 14v to 12v and sometimes 11v, but very rarely. Yesterday, I removed one sub, cut the box in half, and wired my sub to 8 ohms with the + going to the left channel + side and the - going to the right channel - side (bridged).

Now, my sub is MUCH louder but is still not getting close to the 500 watts it should. However, after wiring my amp and sub my headlights (I have HID's) and dash lights dim and my motor revs up trying to power the system.

What is wrong? The system isn't very powerful and I have had multiple places do multiple tests and each time my alternator and battery come back as working in great shape.

As of now I have to have my sub on -5 through my headunit to keep everything from dimming.

Thank You //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

my guess is that you're clipping. check the gain on your amplifier

My gain is set to the 11 o'clock position.

Central, but I was just in Chi town for HIN.

The sub is four ohms, dual voice coil.

I ran a single wire from the - terminal on one side of the sub to the + on the other side. I then ran a wire from the remaining + terminal to the + on the left channel and the - to the - right channel of the amp.

Could it be anything else? This is no fun having to listen to little bass.
