Sound like both. But the amp is fried now. It is fixable you have to replace the transistors that is attached to the heatsink. Its a job and a half and need soldering skills.
Parts are just a few bucks on line. What you need to do is open up the amp and disasemble the whole thing. Take the motherboard off completly and look at the transistors for the part number. find the part number and go to this website for a cross-refference fot an NTE part number. http://nte01.nteinc.com/nte/NTExRefSemiProd.nsf/$$Search?OpenForm. Once located the NTE part number. Go to http://parts-express.com/ and search the NTE part number in the search box. Hope this helps.

I have a monoblock amplifier qa1800d quantum q-series this is very hot and now the main fuse blows, do not know how to adjust the bass, the sub sonic and low pass


Mono blocks my favorite!! Lets see if we fix your problem! Mono amps are designed to work below 75hz so this means its a juice hog... I'd start by making sure your grnd cable is properly attached to a good ground the closer to the frame or unibody structure the better you are! seat bolts work the best! next inline fuses are mounted no more than twelve inches from your battery also you might want to consider the gauge of the wire?? That amp should work well with 1ott cable giving you 14.4 volts to the amp... ck these first n let me know how it turned out!!

I am having trouble hookin a 4 channel amp up...im used to monoblocks....so how do i hook it up


the same thing as hooking up your monoblocks, the only difference is your having 4 outputs, that means you can drive up to 4 speakers with this one.

Looking for instalation manual for a quantum audio qca4300 amp


Gotta ask, you tried the net? look up manufacturer and model and you can find instruction manuals for most anything. You might have to pay, but your amp is no good if it's not hooked up, right?

Help connecting the sub


Your sub or amp is probably blown. Do you get any power to the amp? try hooking up another speaker and seeing if you get any signal at all.
