[QUOTE="EvilEd, post: 8442892, member: 636290"] After further consideration I'm thinking this was user error. You make a good point about 2 subs displacing heat versus 1 and JL subs have some advanced cooling capabilities. Also, the JL subs are 600W RMS each so they're only being pushed to 83% at 1000w where the Alpine is being pushed to 100% of it's RMS capabilities. I also upgraded some wiring and the battery so the extra current may be causing harder clipping, I did notice that when I put the JLs back in they are hitting harder than they were before even at the lower gain setting. I'm just surprised because I've been playing with car stereos for 20 years and I've made a lot of mistakes but I've never seen slight clipping eat up a sub so quickly. But then again I've never played with such high current subs. I guess I really need to use a multi-meter at this level. Thanks again for the help. [/QUOTE]
