[QUOTE="Sunriver61, post: 8898534, member: 674687"] I had an JL Audio XDM700/5 and recently the front channels blew out completely. Only used about 6-7 times with no problems and then they went out. I was not pushing it either. Gains were <=3. Tested the front speakers which came in at 3.8Ω (Morel 63 VNC's) on the L&R. The door speakers came in at 4.2Ω Kicker 4x6's (limitations of a 60 year old car) and the sub came in perfect at 2Ω. I used the same 14g wire with the run <15' for the doors and 14g at 5' for the sub. While this was in transit to JL Audio, I used a spare amp, RF R2-750X5 and got a power protect on it after about 10 minutes of testing. Power for the amp is a dedicated 12' run with a 60amp fuse block at the battery and also about 1' from the amp (long story, really hope that's not it...). I also started to get a very soft hum through the speakers with vol @ 0 with the RF (but not the JL). The amp ground tested at [B].[/B]2Ω (not thrilled with this but I don't think that should be a problem?). Any ideas, recommendations, etc., would be most welcome - and thank you in advance! [/QUOTE]
