killerc998 Posted May 18, 2022 Report Share Posted May 18, 2022 I have a crescendo s4 that after 15 mins or plat the speakers sound muffled. Amp is tuned with a dd1, -5db @ 45 on the deck. Clean signal to 49, I don't play over 40. Amp is overheating,which is odd since it's a class d. The old class ab ( hypnotic) in the same spot could play for hours, when you touched it you could hear your fingers sizzle. Kinda disappointed in the crescendo. Any suggestions? I sent a email to crescendo, if no resolve I will send back. Link to comment Share on other sites More sharing options...
Kyblack76 Posted May 18, 2022 Report Share Posted May 18, 2022 At what ohm load? Running what? I know nothing of the nendo S4. SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
killerc998 Posted May 18, 2022 Author Report Share Posted May 18, 2022 Wired to 4 ohm each channel, running 4 sets of the audio dynamic 3000 series components. I emailed Crescendo also. Link to comment Share on other sites More sharing options...
Joe X Posted May 18, 2022 Report Share Posted May 18, 2022 Two component sets will need 4 amp channels, not sure what you mean you are running 4 sets. Link to comment Share on other sites More sharing options...

Kyblack76 Posted May 19, 2022 Report Share Posted May 19, 2022 Never heard of those components either. But they look really nice. If they are a 4ohm load, i dont see why the board would be getting that hot, that fast. Bummer. Does it shut down, thermally ? or just start muffling ? Or both ? Thats a bummer. Send it back. I dont know those comp sets from adam, but, they look quite nice. Best of luck getting to where you wanna be mate. EDIT - for fun, put a meter on the output, when its fine, take reading, then let it eat, take note with meter when it goes to shit. Just for fun.
