It is possible that the set has gone into an error shut off. Please disconnect the power and allow it to cool off. remove the sub woofer connections if the amp does not turn on again. check for any short in the coils. reconnect the sources once again , making sure that the source is coming into the amp. If there is still no output, remove the cover and check if the main amp is shutting off due to any short in the output. You will need to confirm this out as you had run this a little too much in heat. replace the shorted mosfets if confirmed. hope you get this right. Good day

How can i get my speakers fixed


It may not be the subs, but the amp could have caused the subs blowing/freezing up. If an amp is clipped it will send to much voltage to the subs, thus blowing the subs. Clipping the amp is when someone sets the gains on the amp to higher than the sub can handle. Find this out before you buy new subs. If not, you may have blown subs again.

Hi i purchased the bnps102 woofers and used them for 2 weeks i really enjoyed them and i also purchased the pyle 1400 watt amp and a jvc deck along with the boss amp kit installation now the speakers about...


If the lights on your sub box aren't coming on it's either your ground of power wire came loose or the transformer blew. As for the subs, make sure all the connections are good, especially on your RCA wires. If your amp is getting power, then check your speaker connections. Also, make sure to turn the gain know up. The gain knob is located next to the RCA input on the amp. Let me know if this helps.

Can i use my jensen jxp340 amp with my one 800watt 12" 4 ohm subwoofer?


Yes, technically you can, however you will be putting both your sub and your amp at risk. One of the worst things you can do to a sub is underpower it. The easiest way to explain it is n ot giving enough power to the sub leaves it starving for power. The motor structure ends up working too hard to try and move the cone properly and what happens is the sub will usually seize up rather than blowing out in the term you usually hear (ie, I had my system cranked up and I blew my subwoofer).

Secondly, in an attempt to get any real sound out of the under powered sub, you'll probably end up cranking the gain and bass boost on the amp which ends up overworking the amplifier quite a bit and can in turn lead to fried out amp chips, burnt up circuit boards etc.

Thirdly, by maxing the gain bass boost you're going to end sending a lot of distortion through your subwoofer in an attempt to get some decent bass. Distortion kills both subwoofers and speakers alike.

So to answer your question, yes you can hook up your subwoofer to that amp and yes, it will probably play for a while but I wouldn't recommend it. Look for a class d or mono block amp to push your sub as these will give you the most power and best heat dissipation. They are designed to push subwoofers specifically and you will get better sound and longer life out of your equipment. A good rule of thumb is look for an amp within 100-150 watts of both your RMS power handling and your Peak power. Remember, when it doubt, always go a little bigger on the amp side of the spectrum. It's easy to "tune down" an amp by having the gain and bass boost at a lower level (50%, 25% etc), than to turn 'em all the way up just to get some bass and end up prematurely blowing out your sub, amp or even worse, both.

My sub has all bin wired up proberly the sub works for about 30 secs then the green light goes out and no power to the sub at all


Green light on amp?? Seems like your amp is going into thermal overload. Check your power connections, and make sure there are no shorted wires. Hope this helps.

Infinity ps-10 powers up but no boom


Try hooking up a different signal input to your powered sub, another stereo or even a dvd players audio output to the sub will work for a test. Just make sure the subs gain is down before starting. If it still not producing sound, the subwoofers amplifier is bad. I hope this helps.

Subwoofer Trouble


Turn the bass gain all the way down., Turn up your your volume on bass test song. Crank up the little box next to the steering wheel wide open . Now go gradually turn up the bass gain on the RF amp until you get distortion. Turn the gain down slightly. Now you can enjoy playing the bass from one end of the little boxes setting to the other without ovrloading your amp and subs. Open a can of whoopass on anyone who tries to crank up on your gain.

Subwoofer seem to be broke


The one sub that you described is gone, there should be no reistance at all when you push on them. It sounds like you got your gains set to high on that amp (maybe the amp is underated for your subs). When you turn up the gain to high your cause your amp to distort and it can get as bad as sending a pure DV current to the sub. That DV current will blow subs because of all the force directed in one direction. If you think about it the amp takes a DC current and turns it into a AC current which creates the frequecy (rate at which it alternates) that alternating current pushes and then pulls on the sub keeping it within its boundries.
