Question about Pyle 1800-Watt 2-Channel Bridgeable MOSFET Amplifier Car Audio Amplifier

1 Answer

Amp only runs on 1 channel til it is bridged tried 2 sets of rcas and still the same problem

    If the amp plays through only one channel and works with the speaker connected to the bridged terminals, the amp probably has a problem with the preamp circuit. Try all of the controls in all positions to see if one of the controls is working intermittently.

Either the source isn't moving signal through stereo/both plugs, or the amp is damaged and will need repaired by an amplifier technician.

I have Sony xm-2165gtx amp 165 watt rms x 2 at 4 ohm 200 watt x 2 at 2 ohm 400 watt x 1 bridge output at 4 ohm stereo or bridge mono output 4 ohm stable in bridge mode this mean can't go lower then 4 ohm...


You can't bridge that amp onto a load lower than 4 ohms. So you can't bridge that amp onto two 4 ohm subs. To get the most power out of your subs is easy. Run one channel to one sub and the other channel to the other sub. 165 watts RMS is plenty for most subs.

How to wire a crossfire vr602 2 channel amp at 4ohm and 2ohm


I would be more worried about the amp than the speakers, those subs should handle the watts with no problem. The problem will be in the amps ability to remain working with a bridged 2 ohm load. It may not even stay on without going into protect mode with a 2 ohm load. If it does stay on then it may get really hot and shut off from the heat off of the Mosfett Transistors, or it could burn the Mosfetts from driving them too hard. Basically it's your choice, run your amp hard and gain more volume or run it with slightly less sound and have a cleaner sounding more stable amp that will stay on and have less chance of being damaged. If it's not loud enough the best thing to do is buy a different amp that better suits your needs and fits the application. In your case a 2 ohm stable Mono amp is going to be your best bet or a 4 channel amp bridged into 2 channels and run with 4 ohms on each channel. Or another exact matching amp like your 2 channel amp bridge them both and have each powering 1 of your 4 ohm subs. I used two VR mono amps to power my two 12" 4 ohm subs for a few years

300W Pyramid PA305 protection light


What is the speaker load in Ohms that you are running? Or what exactly is hooked up to it? are you bridging it? The protection light will come on if the load is too much for the amp to handel. If the load (in Ohms) is less than the rated load that it can run, it will stop the output to keep the amp from self destructing. The amp will sense that the demand for power will be too high for the amps circuitry which will either make the amp get so hot that it will burn up the copper on the board or more likely burn up the power mosfetts that power the speakers. If the Ohms are within range then it will allow power to flow through the circuit until the rails that the mosfetts are bound to until they get so hot that it will go into thermal protection. So if your amp has both thermal and overload protection lights and the overload is light then the load is probably too much for the amp. if it's bridged in mono the you can only have 1 speaker setup hooked up it if it's a 2 channel amp. a 4 channel amp bridged in mono for both front and rear channels will be able to have 2 speakers rated a 4 ohms each hooked up to the amp 1 set per bridged output or channel.
Try it running in stereo with only 1 speaker per channel and see if it will produce sound. If not then you have an amp that has internal problems and will need to be serviced. Check your warranty to see if you are covered.

Power Acoustik LT 980-2 clipping while bridged pushing 1ohm load


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!

Pioneer car audio amp GM 6300F (new)


Does your amplifier have a Channel swith which says 2/3/4 channel mode. If so and you are running the amplifier in Bridged mode, try changing the setting to 2 channel or Bridged mode.

I have a audiobahn a400t and im running 2-12''jh45 mtx jackhammers the speakers are wired in parallel stabel @ 2or1 ohm. the speakers are in a ported box. how do i run my wires to my hook these up right to...


Hello rattle822,

A pair of JH4512-04's can be wired to 2 ohms if the subs themselves are paralleled. There's only one voice coil and it's 4 ohm. If wired in series, the final impedance to the amp would be 8 ohms. They cannot be wired to 1 ohm.

In bridged mode, your 4-channel amp is only stable down to 4 ohms. You can bridge 2 of the channels to provide a relatively low 200 watts RMS X 2. The best power solution for your subs would be to bridge channels 1 and 2 and wire one sub to it. Likewise, bridge channels 3 and 4 and connect the other sub. If you connect both subs in parallel, the impedance will be too low causing the amp to overheat and possible fail.

As for the settings: Low pass filter on, crossover somewhere between 80-100, input levels to match your receiver, and bass boost to your personal preference.

Hope this helps.

I have a 2 channel amp pionner gm 510t 760 watt and i have 2 subs how do i hook them up for the most kick and the hardest pound do i run them series or bridged or whats the best way ????


If you bridge it, it makes 2 channels one channel so you can only have it going to one sub. So you'd have to run them in series and have one sub per channel. If you want lots of bass you need to turn the gain up and adjust the settings on the head deck.

Ok . i have a pair of crossfire subwoofers, @


Your amplifier is 4 channel... and only 2 ohm stereo capable.

You will get the most power putting 1 subwoofer wired in parallel on each BRIDGED channel.

This will give you a 2 ohm stereo load.

Both + on 1 subwoofer to + terminal on amplifier bridged channel 1
Both - on 1 subwoofer to - terminal on amplifier bridged channel 1

Both + on 1 subwoofer to + terminal on amplifier bridged channel 2
Both - on 1 subwoofer to - terminal on amplifier bridged channel 2
