It depends on how many channels are on the Amp. If it's a 2 channel you can bridge it using the positive on one channel and use the negative on the other channel. The Amp will give the sub more power bridging the sub.
HelloAny one channel circuit of the amplifier has any sort of trouble, the amp will go to protect mode. It may be a direct short in it he output circuit. This is the common fault for these type of amps. A through check should be done to find out the reason. You must have sound knoledge in electronics, and experience to do this work by yourself. In most cases, unlike TVs, amps circuits are quite complicated and user cannot do it by themselves. OK.
Hello, your problem is that your amp is rated at 4 ohms bridged mono ans 2 ohms stereo. If your running it in stereo you need to raise the ohms to 2 ohms a channel and if your running it bridged into 1 channel you need to be running it at 4 ohms. Please rate this solution please so I can prgress on FixYa.com. Thanks!
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
On your amp, there should be a switch (on the side probably) that has "LP", "HP", and "FULL" or "OFF". This is a switch for the low pass/high pass filter. Switch it to "LP" as this will allow only low frequencies to go to your subs, what you want. If you don't have that switch, go to an audio store or online audio supplier and get either a low pass filter, band pass filter, or a cross-over, and follow the wiring diagram that comes with it to filter out the high frequencies before they get to your subs.
