I think i may have fried my amp :(

I was bassing yesterday when suddenly the music just cut off. I double and triple checked all the wiring and everything looked good.

I put a multimeter on the outputs of the amp and got nothing. (i'm supposed to be using the v~ setting, right?)

I put the rca's from my interiors onto the sub amp and nothing.

it's strange because the power light is on on the amp but the head unit isn't.

i put the dvom on the speaker inputs and it still shows 1 ohm (i'm assuming that means the sub is still ok)

Thats a bit confusing..

You said ALL music. Subs and interior speakers?

Did the headunit die? You say the power light is on on the amplifier, but the Headunit is dead.

You might want to expand a bit.

It sounds like the head-unit has died.

If all speakers no longer work that rules out that the sub amp or the sub being the problem.

When you checked the amp and read no volts that is because there is nothing to amplify because as in no signal. If your amp still gets power do a simple test of taking an music player and convert the 3.5mm TRS to a pair of RCAs and hook it up to your amp, you wont be able to power them much, but enough to see if the amp is dead.

Thats about the best I can say with the details given.

make sure

12v at Remote

and

12v at Main power line...

I've seen a remote wire turn on an LED...but dead 12v wire.

That is a common culprit - a disconnected remote wire, the amp will indicate that it is on, but there will be no signal. Check that out first before anything drastic.

When it died were you pushing it really hard? And for how long? If it just died for no real reason, it shouldnt be your amp.

i was beating it pretty hard, but it was only for like 20 mins. i had the gains set slightly above recommend b/c i thought these amps could take it.

i'm sure it's not the remote wire though, because i have one wire spliced to the 2 amps and an eq.

Seems like something else was wrong, it wasn't because of the fact that you were "bassing". I'd say probably an issue with the amp itself.

do you have a multimeter? check the voltage going to the amp. If its lower than 12v, check your distro block/cap whatever is splitting your power and check your ground. If you dont own a DMM, try a different amp to rule out the amp going bad. If the second amp works with nothing changed then voila. If not, obviously something else is going on.

question: when setting gains, do you guys use an attenuated test tone or not?
