[QUOTE="203_530i, post: 8750415, member: 683305"] In my 2003 W 530i I had 1 Alpine Type-X W12D4 in a Skar 32-36Hz vented Blbox wired to an Alpine V-Power 1000M Amp that kept over heating so I replaced it with an Alpine Type-X A90M Amp running to a Soundstream VRN DD7HB Headunit w/ Memphis 2 Farad Cap. The Sub Blew Apart in 3 Months. The Heat Sink literally blew through the center of the Sub. I got that sub replaced under warranty. 6 months after replacing the sub with another Type-X W12D4 the exact same same thing happened again. I checked all the wiring everything is good, I can't make sense of this. I have had Alpine Subs my entire life. Other then these Type-X's I was running Dual 15" Alpine Type-R's wired to a Alpine V- Power 2000M Amp. I abused the shit out of that system for over 12 yrs and never had any types of issues other then is draining my battery because I didn't have a Cap. I would still have that system today if the subs didn't get punctured in an accident (I loved that system). If anyone has any ideas as to why this keeps happening please chime in. Any ideas as to why would be great. Thanks in advance for your help. [/QUOTE]
