I think the problem was solved....I was tuning with engine off and my Optima got drained, amp wasn't getting enough voltage obviously. This amp sure is power hungry.

I ordered 2 SSD's on May 29th and they arrived today. My UPS tracking number said "billing info received" for 8 days before an actual delivery date was posted. It took 14 total days from the time I ordered till I got them, not bad imo since they build to order.

Ok, after turning it on again without the DMM the noise is a constant buzz (very very faint) as I turn volume up the buzz or hum starts to crackle, but it does not go away even at no volume (the crackle goes away as volume is decreased) .

It's not a squeal, it's more of a cracking or popping sound, sort of like a bad connection popping, but real faint sounding. I'll go look everything over again but I'm confident everything is right. BTW, I'm using a 50Hz tone and the DMM is connected to the outside terminals.

No speaker has ever been hooked up to it, just DMM. My Fi's won't be in until later today. I'm trying to get it tuned before they arrive.

It sounds like it.

This might be a dumb question but I'll go ahead and ask. I was tuning my 1200d for the first itme this morning and before I could reach the 35v suggested voltage with the DMM, the amp started making a faint popping, buzzing sound. My target volume is 21/35 and the noise appeared at about 13/35. The noise went away as I turned it down. I'm running 1/0 gauge from front to db block and a run of 4 ga for 5' to the amp. BTW, no db gain was used and the remote gain was at 1/2 with susbsonic set a 28hz a x-over set at 1/2 as stated in manual. Anyone experience this before?
