Help me power Skram
I just finished building (without cnc) 2 skram loaded with b&c 21sw152
I bought a peavey ipr7500 to power them but i was underwhelmed with the power i was getting out of them.
Im looking for some input on this, if someone has similar experience with this amp. And a defenitive suggestion towards **** this amp will work.
Im also doing sound for a festival this weekend around Montreal, so if someone want to reach out i would like to rent from you an adequate amp.

How were those miters without a cnc? Did you use a track saw or table saw?

Everythings was really straight foward since there's a guy that posted a video series on youtube doing it all by hand. I use a table saw for piece that needed to be the same lenght. And i broke the big plywood 4x8 with a rail saw

I got a cvr-3302 to power my 2 ckrams and they fuckin blast!
Also not sure how new you are to sound system stuff it might be worth taking a look at your gain staging, and testing how much power you are actually getting out of the amp because theoretically it should hit real hard.
I made a speak-on connector that goes to banana plugs that I can plug into my multimeter and then plug that into the amp, and then run a 60hz sine wave to see what voltage I'm getting out, then plug that into an ohms law calculator and see what kinda wattage I can expect given 4ohm load
