[QUOTE="drkodin, post: 1337305, member: 545032"] Copied from CAF cause i really need an answer if i have to rip out a bunch wires (time to do it more than anything) The setup: Pioneer 940mp Diamond Audio HEX 600s powered off a Lanzar OPTI 500.2 (this amp has the problems) 2 12" XXX off a Directed 2400d 0awg power from yellow top under hood to yellow top in back of 04 Trailblazer both amps grounded to rear batt, + run from rear batt through fused distro into both amps Remote wires and HU Turn-on wired to switch (long story that isn't worth telling) The Background: There were a few threads a while ago about amps either not starting up or just shutting off once the cold weather hit. I myself started having issues with my 500.2 when the cold weather hit and have never had any issues in the 2 years that I have run the amp. The amp works fine when it powers up but will also turn on or off randomly, and it only started about a month ago yet the install hasn't changed in over a year. The key bit of info that could help in the diagnostics(sp?) is that a co-worker used my truck on a working trip and the issue happened to him. I drove from TX to Indiana and didn't have any problems at all, he then started to use my truck to drive around town and mentioned to me later that evening that sometimes the front speakers just cut out, then came back in after about 6sec or so. I never had this issue before and he was using burned cds so i just said ok and didn't think twice about it. Every time he used the truck he said it happened randomly, including his drive from Indiana to TX (i had to stay and work ). After i got back home and used the stereo i never had the issue he complained about.....untill now. What i've done: Replaced speaker wires from amp to xovers and chaecked all connections Amp is getting 12.4V when car is off (remote and +), 14.4 when car is on Grounds are good both batts are good 2400d has no issues what so ever and shares remote, ground, and + connections. MOST IMPORTANTLY: Today i finally caught the amp having its problems when i could test it with a dmm. Works fine then all of a sudden the green power LED on the amp fades out and the music cuts out, yet the amp was still getting the regular feed from the remote wire. after a while the LED fades back on (still green, never even flickered red) then a second or so after full illumination the music kicks back on. Finally, the Question!: Before i rip all the wires out of my doors to replace them, which i was going to do before i caught the amp with a dmm, is this just the amp finally going bad? I don't mind getting a new amp, i'll have to save for a little but as long as we are 99% sure that is the issue i don't really have a problem. I personally, with the knowledge i have and what i have seen install wise, want to say the amp is just on its last life and needs to be replaced, but i want more opinions before dishing out $300 just to have the same issue. also, a side question: for those who know, is the ed 200X or whatever the model is (200rms x 2) a good amp? Is it worth dealing with ed? the last time i ordered from them i finally got my stuff 8mo later [IMG]//content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif[/IMG] .
