so after finally getting everything tuned to where i wanted and set-up i was driving around for a little bit and then out of nowhere there is no bass... pulled over right then and checked the amp.. blue power light is on, no sign of protect mode at all. after work i got home and checked my fuses, all is fine. other speakers are normal, but when i checked speaker outputs from amp there is 0 volts. how do i fix this? hope its not that bad, was just starting to enjoy it all again! its a sundown SAZ-1500D, I've only had it a couple months, but i did get it from Db-r.com, but he does good work, no?

Instead of coming on here you should of talked to db-r.com, since he fixes amps he could probably give you the best troubleshooting advice or tell you if it needs to be sent in to him for his repair.

yeah i was going to do that in the morning, was just wondering if someone had an idea of what could be wrong and if it was an easy fix or not...

If you have another amp, put it in place of this one. It may be wiring or something.

If the power is on, I'd check the rca's first

im e-mailing chris about this all. he had me check some cap. inside the amp, but those were fine. i dont have another amp laying around that works how would i check the rcas? they are brand new from knu

made sure the rcas had proper connection and they seem fine. but when i had my DMM reading for volt rating and i moved my bass control knob, there was about .2-.3 reading every time i turned the knob, but it would go away very quickly. is that just a reading error on the meter?

Go get some cheap rca's, Sundown Amps do not like the expensive or top-notch rca's. I got my rca's from Autozone, the Tsunami kind for $9.99 (all sizes) and they work fine.

these are the "cheap" ones from knu, the klarity kable. they are 8$... my dad just got home so im going to hook it all up to his car, it already has wires run and everything so ill see what happens there...

so the amp will work fine and then cut out? but the amp doesnt go into protect? if thats whats happening i had the same problem with my 3000d. it was the mosfits near the rca input..

Try hooking up some other source to the amp, like an mp3 player or something. Or since you have a DMM you could just measure the voltage coming down the RCAs, if there is any.

i hooked the amp up to my dad's wires and there was MINIMAL voltage, even when moving the gain there was never more than 1.2 volts, and that was still just for a quick second.

it just flat out didnt play at all after. i have it all out of the car now. and no, it never went into protect mode.

what setting on DMM do i check my rcas? same as testing on speaker inputs?
