Amp stuck in protection mode, help!!

My entire system was installed by a person @ tweeter... got 2 12" mtx's, a zx750 kicker amp, pioneer deck... my amp usually functions very well.. recently it has been cutting out my subs and flickering on an off from green to red (protection) ... could the amp be drowning my subs? ... subs are running 900 rms .. amp is 750 wattage.. only had this problem once in the past, but now it is occurring more often... idk what to do

For 1 the amp is no where close to strong enough for the subs and 2 if the amp is mounted on the box it is vibrating the electronics loose. you always want the amps rms power to be be about 25% more than the speakers rms rating, from the sound of it you are either undriving the amp (clipping) or running the amp at 1 ohm load which is making it burn up. if the amp gets hot (which class d amps should never ever do) then try running just 1 sub. if the problem goes away then you know the amp is not enough for the subs. try a hifonics amp you will be amazed at the quality and power difference. I sell all major brands cheaper than almost anywhere. let me know the exact model of the subs and i can recommend a better amp for you.

    sounds like the output board is bad, not worth fixing it if thats what it is. I used to sell fosgate but i only do it on special order now because they have had so many similar problems.

I have 2 different subs in one box, a 12" MTX thunder and a 12" Kicker CVR. the kicker is a dual voice coil while the MTX I dont believe is. Can I use one amp for this set up? And how would it be wired?


im guessing both speakers are 4 ohms ..mtx 4ohms and kicker dual 4ohms..now if your amp can go down to 1 ohm wiring the kicker dual coils in parallel (2ohms) and the mtx connected together (4ohms) should leave you with a final impedance between 1 and 2 ohms ...i suggest you use one or get another

Toxic tx 600 amplifier


You need to get another amp for your sub. I would say if you want good quality go for MTX because I have had amps from MTX and never had a problem. what you need to know is look at the fuses on the amp if there are 3 of the 25 amp fuses on there then it should push out about 750 watts but on MTX they under clock the amp so it will push about 800 at 14.4 volts for that you will need a 4 gauge wiring kit with a 60 amp fuse in the fuse link. As far as your other amp hook up the speakers and tweeters to that but be sure to tune in down and you would need a 8 gauge wiring kit. I hope this helps you.

Bass cut off when volume is too high


When an amplifier shuts the Bass off that means its going into protection mode otherwise it will burn out the outputs. One way is to turn your gains down, Pioneer amps are not the best amps for bass out there, they are more for car speakers, I personally wont use a pioneer amp to run my subwoofers especially if they are hard driven subs like JL , Kicker Solo's and MTX subs. But for now just turn the gains down to 3/4 and that should help u, you can also install a fan to keep your amp cooler, if this never happened before in 5 yrs and now it does then that means your amp is just tired and the inside components are overheating easily, thats common with Pioneer and Sony amps.

Good luck buddy.

Only one of four speakers puts out sound!


Check all your RCA"smake sure they all have output..Then use a fluke metere, or any meter you can get that tests ohms, and measure each speaker..they should all read arround 4. If the outputs from the deck are good, and the speakers measure correctly, then you have got yourself a bad amp.

My subwoofers will not play


go into the menu screen on the pioneer unit and go to setting if you have a loud function there turn it on.... if that doesn't activate the amp ...(did you hook up the blue wire from pioneer deck to amp and run it threw the car to the amp)..if no than your pioneer deck does not realize there is an amp present in system....... if yes scroll threw menu till you see audio look for Sub Woofer or Amp you may even have a button on pioneer deck marked SW go press it and turn amp to on this will provide signal from pioneer unit to amp if this doesn't work other thing could be you hooked RCA to AUX input (but if you have a SW for RCA plugs on back of unit make sure the RCA wires are in it) the loud or SW button should activate it (if there is only F and R for RCA plugs on back of unit use R hope this helps)

Kicker L712 and rockford fosgate800a2 amp.weak prfmce


Is the box sealed air tight, leaking around speaker? plumbers putty works great. Amp may be good enough for the mtx but underpowered for the kicker. When kicker says 1000 watts that what it is (at a 14.4 volt input). Mtx is ok but may not tell the true watts. Check to see if the speakers are the same ohms also!

Car sound system. only sub is giving off sound. other 4 speakers dont work at all


Could be bad outputs from the back of your head unit or also could be bad rca cables. Make sure the amp is on and powered.

Red light on Amplifier


if your amplifier has the internal Kicker card dealie "little computer card on the side that you can change out crossover settings and such," Turn off the vehicle, remove this device and make sure the contacts on the card are clean and free from black soot (showing a spark). clean the contacts with a pencil eraser or something hard but soft... and put the little card back in place, start the car again and see if that helps, I used to lose one speaker every once in a while with the same amp. I ended up replacing the module with a different one from my dealer and it worked fine (still does and it's been in my car 6 years). Check that little module. if this doesnt work, while the car is running and the music is "playing" wiggle the card and see if it works sometimes and not others. Likely is the little module.
