Yep. Finals in amp or possibly wire touching somewhere...even voicecoil in sub. Try with a different sub if possible. Process of elimination.

Seems that the output stages of amp are blown and it shuts down for self preservation. When you do a lot of blasting amp failure is common especially if you use an equalizer to "soup things up." If you are blasting along at 1000 watts and you add 3 db of boost at a frequency the amp will double the power at that point, If you go up 6 db now the power is up to 4000 and exponentially. And transistors are not like tubes that know their limits.- given the chance they will simply blow themselves away providing power they do not have! You have to be careful at high volume levels.

You're using the wrong control wire. You're likely using a wire marked antenna control. You need to use the one marked amp control. They are both blue.

SOURCE: can a 1000 watt amp run 800 rms subs and best wiring option

yeah it will run them but you won't get your full power because the rms for your subs is high. try bridging them with some 8 gauge wire, and of you got a crossover it will help you out alot

SOURCE: How to wire a sony 1200 watt amp

I believe what your trying to do is to run 2 12" subs and some other satillite speakers? We used to do that all the time.. That is called running the amp in "mixed mono" that's where the mids & tweets are run in stereo while the subs are bridged mono. This configuration is what made Rockford Fosgate "The Bomb" back in the day. To do what you want your subs have got to be 8 ohms, NOT 4, Dual Voice Coil 4 ohms would be OK. Before i tell you how it can be done let me tell you what will happen... For one thing you will be "making" your own cross overs for the subs and mids and tweets. Forget about using the cross overs on the amp. 2ndly you will lose about 1/3 to 1/2 of the amps power because the crossovers are so inefficient, so don't even think your going to get anywhere near 1200 watts from the amp. More like 300, and that's on a good day. But if you still want to do it you go to your Radio Shack and get 1ea 6.0 mHy (milhenry) coil and two 47 mfd (microfared) capacitors, or something close to that value. So you would wire your mids & tweets normal in stereo and on the + line to each mid wire in the 47 mfd capacitor. That is your h/p crossover which will crossover your mids @ appx 130hz. Now on your subs. You want to wire them in parellel (both +s twisted together and both -s twisted together so it looks like there is just one woofer with a + and a -) Than from the L+ of the amp run a wire to the coil and from the coil to the + of the woofers, than using the R- of the amp to the -s of the woofers. Do not use any of the amps built in crossovers leave it on full. Good luck. Mark @ Sounds Good to Me Tempe, AZ

SOURCE: amp turns off

what ohm is it running at? if you have all three hook up it parallel then its to low of ohms and it would be louder if you unhook your 10" sub as it moves differently form the 12"s and it cancels out some bass. but if you want it then you have to change the wiring around a bit. take the positive wire off a 12 and put it on the positive side of the 10 and then take the ground for the 10 and hook it up to the positive side of the 12. so you should have one wire from the amp going to the negative side of the 12 and one going to the positive side of the 10 and a jumper wire from the 10 to the 12. and if it still shuts off then you have bigger problems.

I have 2 12in kenwoods and a 1200 watt pyrimade amp, how can i hook these up to be the loudest


1st have your subs facing inwards towards the front of the car, not facing out the boot, This creates a better bass.

Wire 1 sub to one channel and the other sub to the other channel.

Turn down your gain as low as possible and then power everything up.

turn volume to desired loudness and then start turning up the gain slowly, if distorts a little turn in back down a notch.

avoid using bass boost, I agree it sounds great but it puts more strain on your amp and shortens its life.

after sorting out your gain, tweak all others until sound is bassy and clear with no distortion.

If you would like to use bass boost, turn on bass boost first, then up your gain etc.

I have two 12' kickers, will a x-plore 1000 watt 4 channel amp work well with it?


It all depends on the wattage of your subs. you need an amp more powerful than the both subs combined. For example. for 2 500 watt subs, you'll need at least a 1200 watt amp. amps should never be truned up to full power, 80% max as they tend to blow more quickly and overheat when on max. ideally you want an amp over the total combined wattage of your both subs so you dont need your amp on max for the best sound for you subs.

Amp makes noise. I am purchaseing a new amp


Hello termite440,

A mono amp will generally provide more power for subs. And for those Audiobahn's, you'll want something that will provide a minimum of 500-600 watts RMS to each, a least a 1000 watt amp. At the low end, something like the Alpine MRP-M1000 or the Orion HCCA-D2400 will provide 1000-1200 watts. I'd recommend the Alpine. For more power, and another $100, look at the Alpine M2000, or for another $250, the Rockford-Fosgate T1500-1bd.

Hope this helps.

AMP shuts off


your problem could be in the fact that you are trying to overdrive the amp. sony will not carry a 1 ohm stable load and if your speaker are 4 ohm speakers wired in series then you cant drive the bass your looking for. try using soundstream tarantula amp or new hifonics block mono class d amp with about 1000 watts rms. what kicker subs do you have? that will also make the difference in amp choice. im running tarantula on 4 polk momo 4 ohm 12's and has broke my back glass in my jeep twice one time was for a show. oh well let me know. happy boom boom. i'll be glad to help

High distortion


The head unit may be rated at 200 watts but it cannot produce more than ~20 watts of real power per channel. There's no way that it can drive the high end speakers to a level that will be needed to compete with the subs on a 1000 watt amplifier.
