[QUOTE="TravDrew, post: 391143, member: 553158"] Hey. Recieved my 2 RE HC 12"S in the mail the other day, and went to install yesterday. I only built a box for one atleast for now, so I was hooking up a 2 ohm DVC HC. The amp I have is a mtx 81000d. I drive a 1993 Honda Civic Ex. My deck is an Alpine 7874, and insides I have a set of Polk and Infinity 6.5"s. I run 4 AWG wire from my battery to a 2nd battery in my trunk, an Everstart Extreme Deep Cycle battery. I built my box using the diagram emailed from RE, ported box tuned to 35 hrz. I have an 80 amp fuse between front battery to trunk battery, and hooked up a 150 amp fuse between back battery and amp. I first grounded my amp, then connected the RCA's. I ungrounded my trunk battery, then tried to hook up the power wire from it to my amp, which let of a spark. I then took out my 80 amp under the fuse, then hooked up the power wire to amp, without a spark. Plugged the amp back in, then grounded the trunk battery. I started the car, noticed the red power light on the amp was on, but no noise. I turn up volume to about 7 (out of 30), then quickly notice smoke pouring from my trunk, which was open. I run back and see a continuous flow of smoke coming from the port, and a horrendous smell. We quickly take the sub out, and at first could not figure out where it was coming from. The sub did not feel even remotely warm, we then lifted the sub and noticed it was coming from the hole on the bottom of the magnet, which was warm and letting out smoke. My amp had 2 sets of positive and negatives. I connected one positive to the positive on my box terminal, and the negative right next to it to the negative on the box terminal. Inside the box I wired it according to rockford's wiring wizard, which should have made for a 4 ohm load. I used 12 awg speaker wire, and 4 awg power/ground. Was curious what could have been the cause of this? About 2 hours previous to installation, my cat knocked the amp off the lower portion of my computer desk which was about a 1.5 foot fall, obviously not good. The only other problem I can think of is if my back battery wasn't fully charged, as it hadn't been ran in a few months (I previously had 2 bazooka amps running off of it, I abused them however, and they blew in a few months). I am still not sure the severity of the battery if it was not fully charged, but figured since I would only turn volume up to about 7, the amp wouldn't draw as much power, and it might be able to recharge itself over time. I could not tell if it was the amp or sub making a hissing noise, but one of them did for about the first 3 seconds. Any suggestions? Thanks in advance! [/QUOTE]
