[QUOTE="XPerties, post: 6998585, member: 615994"] I got a SClass Shallow mount (15-SC12D4) and had it wired to a sony 800w amp (RMS around 250) for about 2 months but then a few days ago I got a JL e1400d mono amp rated at 500RMS which is exactly what the Memphis sub is rated at. I had it wired to 2ohm based off this diagram: [IMG]http://www.xperties.net/photos/d/35816-1/1_4ohmDVC_2ohm.gif[/IMG] I checked and double checked wiring and it is right: [URL="http://www.xperties.net/photos/d/35807-1/IMG00071-20100912-1109.jpg"][IMG]http://www.xperties.net/photos/d/35808-2/IMG00071-20100912-1109.jpg[/IMG][/URL] [URL="http://www.xperties.net/photos/d/35810-1/IMG00072-20100912-1110.jpg"][IMG]http://www.xperties.net/photos/d/35811-2/IMG00072-20100912-1110.jpg[/IMG][/URL] ...and local stereo shop tuned the amp to these settings: [URL="http://www.xperties.net/photos/d/35813-1/IMG00073-20100912-1110.jpg"][IMG]http://www.xperties.net/photos/d/35814-2/IMG00073-20100912-1110.jpg[/IMG][/URL] When I told them I wasn't happy they said it sounded like the sub was under powered so they ordered one of the new memphis line amps and I was going to stop by there Tuesday but last night while sitting in the parking lot of my job I was video taping the voltage drop I get to post that to another thread when all of a sudden...BAM...sub smoked. Smoke was every where..... Start video at 1:35, sub fries at 2:19 [URL="http://www.youtube.com/watch?v=d2v2TKPGv8Q"]http://www.youtube.com/watch?v=d2v2TKPGv8Q[/URL] Any suggestion? Would the JL really bake this sub? Is it possible the sub was just a lemon? I have 0 gauge running from battery on a 150amp fuse to dis block, 4 gauge going from disto block to JL amp. [/QUOTE]
