You need to check the B+ and remote voltage on the amp when it cuts off (assuming that you can recreate the fault).

With your multimeter set to DC volts and the black meter lead on the ground terminal of the amp, touch the red lead alternately to the B+ and remote terminals as the amp shuts down. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is dropping too low.

I have a kicker ix 500.4 hookd up to polk audio 6x9 and 6.5. if you play the system past about 25 volume the subs will keep playing but the speakers will cut out for a few seconds as if its hiting the

Make sure your frequency is no higher than 80 on the low and 120 on the high. Check speaker polarity with a AA battery(Speaker pops out when polarity is correct) Make sure the speaker crossovers are working properly. Check your ohm load when you connect the speakers together with a multimeter at the amp. Ohms that are too low = heat. See what your amp is rated for. After all that, turn the gain down all the way, turn up the volume to 25-28 and readjust the gains

Ok i got a mtx 12' 500 sub matched to a alpine mrd-m500 mono amp. The deck powers the 4 speakers, as i turn the volume up on my deck (alpine cde 100) the sub/amp cuts out at around volume 20-22 and E-3...

Sorry,after rereading your problem,I gave a wrong answer.Do you have the deck sub RCA pre-amps connected to the amp,then the wires from the amp to the sub?If you do,you need to check what the sub and amp are rated as such as,peak or rms.They are 2 completely different meanings.Greg

When i turned the bass up to high on my head unit my amp cuts out on overprotection, just for a second and them comes back on. why?

go into your settings in the deck by holding down the volume on most models for 10 seconds then change your hpf settings and your lpf settings your bass will sound much better and not cut out. hpf recommended 160......lpf recommended 140.... good luck

My amp keeps going in and out of protect mode every few seconds it cuts off and then it will cut back on and so forth

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Your amp is probably OK. The volume is either set to high or the speaker load is to low of an impedance. Remember 2, 8 ohm speakers connected is the same as 1, 4 ohm speaker. Another possibility is that you do not have enough battery power coming to the amp itself. A simple rule I use is take the watts and divide by ten, that will give you an approximation of the amps needed on a 12 volt system. This takes into account some of the losses in the amp, but it is only an approximation. For example 300 watts RMS is 30 amps, which will require a number 8 wire to keep the losses at a minimum. You can check wire drops on the web.

Good Luck,

Amp keeps cutting on and off

Do you own a capaciter if not get one. If that dont help check all your wiring make sure it is the proper thickness and lengths.

Amp Turns off after 30 seconds of song play.

Check your ground and make sure it is grounded to metal in your car with no paint. Also, make sure you are running 4 gauge power wire. Another possible cause could be that the ohm load is too low on the amp. Also, if your car battery drops below 10v it will send the amp into protection.

Amp doesnt work

If you've only had it for 3 weeks and it's under warranty, you need to send it to a warranty station.
If there is no warranty and you want to try to find/repair the problem yourself, let me know.

Jl audio e6450 cuts out above mid-volume

take a look at the power, ground and remote wires. the power and ground should be a minimum 6awg in wire size, and the remote wire at least 12awg. it sounds like your drawing a lot of power,so smaller wires usually mean more heat...the amp will turn off into protectedmode if it gets hot or is used for along period of time,so on any road trip make sure if isnt msothered by sleeping bags,coolers etc...just like any major electronic component, it needs room to col off.
