Power Problem, LED Lights up and then shuts off

I have a toggled amp system so that I can shut off the Amps independantly. I have 500 watt 4/3 amp that works fine. I installed a 600 watt 2/1 amp that will not work. First thought that the toglle switch was messed up. Took the power supply of of the amp that works fine and hooked to the 600 and turned on the power supply. The LED comes on and then goes off. I turn off the amps power supply and turn it back on, nothing happens. I have to turn off my radio and turn off the amp and then turn the radio back on and the Amp back on and it stills does the same thing.

Re: Power Problem, LED Lights up and then shuts off

Do you have the switch or activate wire on the new amp. to the right hookup? If you do, then theres a problem with the amp and if your not a tech these can be a difficult thing to trouble shoot. Take back the amp or seek out a pro to test it on a bench. Good Luck

I got 2 10in kicker comps and the rms on them each is 150 watts and can i hook them up to a 1000 watt sony xplod 2 channel amp and do i use both channel or just one or bridge them

1st thing is amps outputs have to be properly "loaded" this value is given in "ohms" if your amp says minimum speaker "loading" impedance is 4 ohms ( I suspect it does) then you may load that 1 channel down to only 4 ohms or amp will be damaged , most speakers are rated in ohm's Impedance (look for Greek symbol for omega) look for its rating somewhere on it doing the electrical formula math if you connect two 4 ohm speakers in parallel to one channel ( +=+ / -/- ) this divides down to 2 ohms (not good) but if you take same speakers and connect in series together (+to-/+to-) this gives you eight ohms (better) , the watts rating is a figure for you to determine the amount of power the speakers will take before failure , hence just because you connect 200 watt speakers to a 2000 watt amp is no indication that speaker will take all 2000 watts ( it will fail long before that point ) watts do ADD together like the above example two 4 ohm 250 watt speakers connected to one channel of amp in series will look like ONE 8 ohm 500 watt speaker to amp of course over 16 ohms load speaker volume will greatly diminish and amps have max impedance loads for them as well although there not often published
this is why I love the old TUBE!!! amps they load all the way down to 2 ohms and go up as far as 32 ohms load with no problems , they sound better as well across the board as well

1991 toyota tercel std... Is the stock battery n alternator enough for three rockford fosgate p300.2 amps? Wondering if I just need capacitor or heavy duty battery and or high power alternator? Thanks

Those amps draw 300 watts RMS at best. So a 900 watts total load will be fine on the stock charging system. All three amps will never be drawing max power for a significant amount of time anyway. Just make sure you run 4 gauge of thicker power wire to the amps to minimize power loss. Use the same size ground also.

Good Luck

Amps turn off and cut out

You just gotta get your gains set up right. Look Up "How To Set your Gains with a Multimeter" your over powering your subs or speakers and your amplifiers cant keep up. you also have to make sure your speakers are wired to the right ohms. your amp cant handle. if your amp cant handle, for Example:1 Ohms your gonna blow your amps. ......Speakers and subs are a science too.

Sleuthing a 300/4 low-ohm issue. 300/4 amp history: unknown. just connected today whole system yesterday/today: head unit, 300/4(to 4 polk 6.5" component speakers brand new) 1000/1 (4-W3's),...

Are you sure you getting enough power to push everything. I have seen when the voltage is too low coming in, the amps will shut down so they don't overheat. Once they've cooled off and the volume level is lowered they will kick in again. Low voltage and a heavy draw will create massive amounts of heat.

Can you run two mtx 6500d amps in parallel for more power?

Not suggested to parallel the output of two amps. Instead take each amp, find out what the amps lowest impedance it can drive is and select your speakers based on that. According to MTX these are stable down to 2 ohms without a rated output power of 500Watts X 1. If you get two dual voice coil subwoofers with each coils characteristic impedance of 4 ohms, when you parallel the two coils you will get a 2 ohm load. Just maek sure the speaker can handle the 500 watts.

No LED power lights go on

the light with the power light(middle) is a blue/purple faint light try checking it out at night.The squiggy(as heat waves) will only light when the amps shuts down due to thermal protection(wait for it to cool). The bolt/yellow (short circuit) will light when there is an electrical overload in any of the wires(check +ve leads).

never attemp to bridge your amps specially this type of amps. this are too very complicated. you may blow your amp if you will attempt it again.
