okay, I upgraded my opus 150psu for the newer 180w psu which has the amp turn-on blue/white wire that hooks to the amps remote input. the problem is that the opus180 psu remote wire is not a 12v wire, so the amp does not see any current when booting up which cause the amp to stay off. the fun thing is that only one of the amps will turn on(momo sub amp), but no the 4 ch amp that goes to the rear and front speakers. These amp are arc audio foose series FD-4150(4ch amp 400watt) and FD-1200( mono 1,100 watt). I called arc audio to see what current or voltage the amp need to see to come on they told me very little( 200milamps). But I told them that the mono amp would come on without any problem, the 4ch would stay off. He then said the the mono amp is very sensitive to any change. But the 4ch less sensitive. so then I called opus about the issue of the amp not turning on. they told me that the remote wire from the psu is not powered, like a double ground just used for signal to turn on devices. it was very hard to understand the guy in tech support. So Ive tired the relay to power the amp to see 12v, didnt work, tried the double ground way with the relay the guy told me, amp still wouldnt come on. So I just wired to the acc which works, but with a big pop which will damage my speakers. So I need a amp delay device that you can adjust the time to turn on the amp. Ive seen products out there, but they are only for a few seconds, need something much longer.
No announcement yet.
need amp turn on delay, speakers pop
