I have an earthquake h10000d amplifier hooked up to 2 re sexx 15s, i have little electrical work done on the truck and i think thats the problem but i wanted to be sure. When i have the truck running and I turn the amp on it drops the voltage ( according to my stinger voltmeter ) from 13.8 to 10.7 volts the amp will pulse like a heartbeat flexxing the subs a little and thats all i can get out of it whats wrong with it?? Tell me what i need to do to make it play im trying to have something at sbn and this is all thats stopping me, thanks guys

For one it's an earthquake.

For two the pulsing typically means something isn't right internally. 3 volt drop is bad just from turning it on another sign

Does it do it at all volume levels. Are all switches where they are supposed to be and not stuck in the middle etc.

does it get worse as volume or gain is turned up. My goes is the amp output is toast and that's whyyou get the pulse and high voltage drop

I would pay very close attention to the phase switch to start

is it worth fixing or would u think to get a different amp, i dont know what the true output is but all i need is 3500 watts and i was expecting the earthquake to put at least 4,000 watts out

I would be shocked if you got anywhere close to 4k out of that amp. But that being said, it does sound shot. I highly doubt you'll find anyone in here say yes rebuild that earthquake amp. HOw much did you buy it for in the first place? Is it new, or used? etc.

I happen to have a Crescendo 3500.1, but you'd have to beef up electrical for it. But at the same time, any amp you get for that kind of power, you're going to need to beef up your electrical.

It's rated at 3k. Earthquake was never known for durability. Or clean power. I've seen them go up when they weren't even playing. Good times.
