jnasty Posted October 29, 2019 Report Share Posted October 29, 2019 Hey guys, so i'm doing the finishing touches on my install and it came time to power everything up. When I powered up the sub amp (4000se), the fans went on max as if i were full tilt on the volume. realized the protection led was flickering red/green. I power cycled the amp and the logo started to flash. it did (flash, pause, followed by 5 more flashes.). power cycled again, and the fans went on again... i get either the LED flashing or fans on max. Hooked up a 8" mid-bass ive got and it sent the cone so far outward, it came out of the gap. realized ive gotta meter the amp, ive got 13.2v in & the speaker outputs are giving me 97.5V DC out??!?!?!??! The last time this amp was used, it smoked a sundown nsv4 18. Could a short on the sundown coil fry the amp?? Arent amps protected from situations like this, especially top on the line amps??

CrackFactory Posted October 29, 2019 Report Share Posted October 29, 2019 Send it to the Amp Lab. www.theamplab.net It's definitely broken if you get DC voltage at the speaker outputs. Link to comment Share on other sites More sharing options...
