I just put in a 200w pioneer amp to power my MB quarts in the front. I have an EQ on my headunit, and i have it adjusted so i can just change the bass and treble depending on what i want to listen to. My problem is that when i have my bass up and the stereo playing pretty loud, my amp cuts out. The low pass filter is off, gain at normal, and its running to crossovers. Any ideas as to why it cuts out on me? BTW, i thought it was my ground, but it looked fine. I re-did the ground anyways, but its still doing the same thing.
Thanks
You are probably asking to much of your amp. You are telling it to put out more power to the speakers/subs than it should. Pushing your subs to the max isn't always a good idea (though it is fun sometimes), you could really mess the stuff up. You also might be over heating it. Make sure it is located in a place where it can breath well, with good airflow.
Thanks for the quick reply. I have a seperate amp going to my subs. I dont think im overheating it because it hasnt been running for a while, and its got plenty of airflow. Is there anything i can do by adjusting the gain? I know the gain isnt just adjusting the power output, im not really sure exactly what it does/ how it works. Usually i dont run it that loud, but it would be nice at certain times.
ur asking too much bass of the MB's apparently... or something. this is weird.
The power handling of the MBs are 50-140, and the amp puts out 50w rms x 2. The speakers themselves are fine, theres no distortion at all at high volumes, so im pretty sure its got something to do with the amp, but i dont know what. Thanks again guys.

When it does cut out, its only for a second or two, thats why i thought it was a ground at first. However, when it does cut out, the amp light stays on. And, the amp is not even hot to the touch.
Anyways, i looked at what "normal" was on the amp gain, and it turns out to be 500mV. My HU is 4v. I turned it down and i think i matched it pretty close. It seems to be working good now, but ill let you guys know otherwise.
Thanks for the help
Another possibility, if it is still giving you problems. you may want to check the voltage coming from your power source... some amps are picky about voltage and just turn off... you may need an new alternator...

New Toyota project coming soon...
The sub amp is not the one cutting out. Its a pioneer, 760w max, 380w RMS, running it at 4ohms bridged. Ive got 8g wire running to the amp for the fronts, its a pioneer as well.
My headlights barely dim, if at all, but I also did new grounds (off of the battery and in the engine bay) with 4g wire.
Ill check the voltage when i get a chance. 12v under idle?
I really dont know why it would just cut out for 2 seconds at a time.
Definetly check the voltage
i know this sounds dumb but redo all of your connections to your amp. my 2 type r's were requiring too much power for my amp (which the amp IS capable of producing) and the connetions werent very good so my amp kept going into protect mode and cutting out. so i went to home depo and got some of those little eye dealies, and hooked it up beautifully.

u might also want to find a new ground, u always want your ground to be shorter than your power wire.

1) bigger wires (4G then distrubution block to 8G)
2) power capacitor
OT
it is acutally more damaging to the speaker when u underpower it, instead of over powering it
Ill check the voltage and redo the connections whenever i get time. My ground is only about a foot and half long, ill see if i can get a better connection for that as well
as always thanks for the help
Voltage was 12.5 at idle. Still having the same problem.
I really think u need a capacitor to supply constant power to ur amps, if that doesnt work try checking all ur fuses. Sometimes when the fuses get loose shiet like that happens >

Whatchu Know Bout In Dash Tv's? - Mike Jones....WHO?
Ill be checking those then..
So who has a cap that i can borrow for a little while? ha
Would i be able to hook up one cap to both amps?
Had the same problem with my first amp...now about 12 amps later I would say you were asking to much of the amp and your over heating it. Your going to end up frying the amp!
