The one thing I don't like about these, is the angled set screws. They pretty much rip the wire apart. Instead of going straight down into the wire, it goes in, and acts like a cutter almost. I've had to remove the speaker wire a couple times now for DD1 / CC1 action, and if I do it again, I'm going to have to cut the wire and re strip it. Otherwise I love mine! They're solid. I beat on my mids yesterday on the way home, about 45 minute drive, and when I got home they were just warm. Not hot, but warm. I think nendo hit one out of the park with these things!

Probably not going to do anything for the speaker wire side, but I think we are going to offer free 1/0 to 1/0 with the 1500.1 and 4ga to 4ga with the other 3. Will have to have them designed and made to fit the angled set screw though.

I look at it this way, I dont mind the angled set screw, it would piss me off if the whole input were angled. I hate those.

Are you offering free1/0 inputs with the amps?

Hey guys, I recently bought this amp and I'm running 2 gauge wire to it to powera pioneer champion pro 10 inch with it but don't seem to be getting as much power as I should be. The sub isdual 4 ohm coils. I even plugged in an old 12 inch premier that only needs 400rms and I could only over power it when the volume was cranked. My head unit is an alpine ute-42Bt and I'm running 4 kicker ks65 from it, could the problem be the head unit? Any advice would help! (First posting in any forum ever so hopefully its in the proper section) Thanks

So I just read something that answers part of the efficiency question. The 90%+ rating is at 2 ohm on the 1500.1 and 4 ohm on the 600.1

Per Crescendos Website

The final outcome of the PCB design enables up to 97% efficiency @ 2 ohms on the monoblock Symphony models and up to 91% efficiency @ 2ohms per channel on the multi-channel models, making them the top tier of efficiency possible in car audio.

Did you ever run this test? I'd like to get this amp and might run at 2 ohms to avoid drawing too much from my electrical.

In another thread people were saying there is no way it is close to 97%, I'd love to prove them wrong. Crescendo seems like a pretty reputable brand, hard to believe they would wildly overstate efficiency when all the other specs check out.
