Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Might be time to rep .A thumbs up would be greatly appreciated if this answer is helpful to you. blown channel - blown-channel-zb4bomd1rt4qms0dqd12kkt2-3-0.jpg

Unless you have extensive knowledge about capacitors, and the internal workings of an amplifier... for your own healt, i would reccommend a preofessional amp repairman. usually a power supply shouldnt cost more than $75 including labor. However, an entirely new Nitro Amplifier can probably be had for not much more. If there are on-board fuses, check to see if that is blown first. Even if it looks good, remove it and test continuity with a voltmeter, and/or ust replace it.

I'm running 8 gauge wire for battery cable and ground cable....my amp.is a momentum 600 watt...2 channel. ....my fuse is blowing every time I hook up either cable...


First of all, what size fuse? Check the amp and see what max amperage is, and insure your fuse is that size. Secondly, I suspect either a blown speaker or blown outputs. Disconnect the speakers from the amp and see if the fuse still blows. If it does, either you are hooking two wires up improperly, or your outputs are toast.

I have a Sony Xplod 800w Amp running a 10' Sony Xplod Amp....i unhooked the amp to do some moving and i tried to put it back in today and it didnt have any sound coming from it! I did notice the power...


it sounds like it could be a blown channel in the amp. if the sub was blown it would still work just sound horrible. i have blown many subs and amps. you can bring it to an audio shop near you and they can fix it. i just got one of my channels fixed for 35$

I have a boss rt645 2ch 1400 watt amp would this amp properly push a pair of 12 inch mtx terminators.


That all depends on the wattage of the subs. also the independance of the subs. If your amp is 1400 watt, maximum you want is 2 600watt subs. if your subs are higher you will blow your amp eventually as your amp isnt powerful enough to pump out to that level.You should never have your amp fully turned up to max, 80% is perfect and will not make your amp blow. Hense why you want your subs less than the max output of your amp.

My pyle plmra 220 600 watt 4 channel amp blew out, pyler said it would be 50 dollars to send it in to them so i said to heck with that and oppened her up and found a capacitor blown, but when i replaced...


outputs also blown, go to ebay and buy a better amp form the same price you would have paid for pyle to fix that one, just keep playing with that one and you will get better at repairs, thats how i learned to fix amps.

Support Question about RMS


you are going to need an amp that can supply the right amount of rms power to make it sound good. these sony subs are rated for 380 watts rms. so in order to find an amp that will supply two, you must multiply that figure by two. so you will need an amp that can supply around 500 to 750 watts continuously (or rms). also you are going to want an amp that is either class d or class ab rated. these amps are built to push subwoofers exclusively and will give you the best efficiency and sound out of your subs. you will also want to get an amplifier is a monoblock amp, and not a stereo amplifier. make sure the amp can put out that rms rating at 2 ohms as two 4 ohm speakers equal 2 ohms wired in parallel. i have a kenwood kac9152d that puts out about 2000 watts max at 2 or 1 ohms (900 watts rms) that i used with my two sony xplod 10's for about 2 years. it was kick ***! now i dont know if you need that much power but they will handle it as long as you dont push them too hard for long periods of time, otherwise you might end up blowing them up! (depending on the box size that is, and the quality of it as well...)

i have years of car audio installation experience and can help with setting up and wiring any mobile entertainment system you can imagine. may i ask what kind of music you listen to and what kind of box do you have for these subwoofers?

if you have any questions email me at thadoggma420@hotmail.com

AMP FOR MY SONY SUBBS


Get an amplifier that is rated just under the power ratings of the subs, that way you will not blow the subs by pumping in too much power to them. An example is, if you have 2 subs that are 500 watts each and you are going to connect them in stereo mode, you need an amp that is no more than about 400 to 450 watts per channel. This will push them very hard, but will not blow them by overdriving them. If you are going to connect 2 subs at 500 watts each in a bridged mode (in parallel across both channels) then you need an amplifier that is about 800 to 900 watts total power for both channels. This is basically the same power ratings for an amp, but some amps are mono (just one channel) and will have just a total power rating, while other amps are 2 or 4 channel amplifiers and have a rating for each channel.

I hope this helps in your decision making, if you need more help let me know. I have been repairing car audio equipment for almost 20 years and have seen just about everything.

2006 12" Kicker L7 4 ohm


first whats the range in terms of WATTS that your 12" sub can handle in 4 OHMS ? second , lets check the AMP , POWER ACOUSTIK 1800 WATTS , Now thats a lot of power to drive a single 12" sub speaker . your amp is 1800 watts , per channel is around 500 watts , if BRIDGE thats around 1600 watts rms for ONE channel , if your sub can handle that kind of wattage fine , but it will not blow the amp , what it does is shuts down , some kind of protection mode , it will come back on after a minute or so. I suggest to use one channel in stereo mode , or purchase another sub to use the other channel. i hope this helps AJ
