[QUOTE="AJStaples, post: 8711388, member: 680574"] Like 10 years ago I bought 2 Polk DB1040DVC subs. They are 50-270w rms. They've been sitting new in box since I never got around to buying an amp or whatever. I ponied up a couple dollars and at crutchfields recommendation, grabbed a pioneer GM-DX874 4/3/2 ch amp. I connected front door speakers (kicker k5 6x8) to channel A I bridged the sub on channel B. I wired the sub in parallel for a 2 ohm load (amp says it can handle) I only want to do 1 sub. I wired it just like the amp book says. Everything seems compatible as far as wattage and impedance. I finished the job, went to a location I could turn the volume up a bit to tune it up. I drove like 3 miles and the sub just stopped pumping. I took it out after I got home, I was sure that maybe one of the connections in the sealed box popped off or something, but when I took the sub out, a cloud of dust and stink followed. The woofer was fully depressed, and basically melted. What did I do wrong? I have another sub to replace it with, but I obviously don't want to **** that one up too. Could the frequency be to low or gain to high?? What should I set these at for these subs. Btw, the door speakers sound great and have no issues. [/QUOTE]
