Boss chaos 150 200 watt that shows light but doesn't produce sound

I have a boss 150 dual channel 200 watt amp in bridged mode that will come on and display the green light but will not produce sound. its hooked up to two 300 watt pioneer 6*9s if that makes a difference. help me please

If this is the CH150, it's not bridgeable. Try connecting it normally (one speaker per channel) to see if it will produce output.

Wiring a crossfire vr602 at 4ohm

OK what you are saying now is that your speakers are dual voice coil; models? 4 Ohms per Coil? I have always used single 4 Ohm Voice ciol speakers since amps are mostly based on 4 Ohm outputs. but you can get 8 Ohm dual voice coil subs also. With 8 Ohms per coil you can get 4 Ohms if you parallel the wires. What is best for you and will get you the most stable power and still will be in the specs of that amp is to run the amp in BRIDGED MODE running each subs voice coils in series with each other then run those 2 subs in parallel to the amplifier giving it a 4 Ohm load. So, your will have two sets of wires from your amp 1 for each speaker. Then you will take a short piece of wire that will connect the + to the - of each voice coil then hook up the wires from your amp to each sub What it will be is 4 Ohms + 4 Ohms = 8 Ohms per speaker the 8 Ohms in parallel each speaker to the Bridged amp output using just the + from one channel and the - from the other will give you a total of 4 ohms and power out put of 600 Watts so that ends up being 150 watts per voice coil or 300 watts each speaker

Does this boss chaos c550 amp match up to perform correctly with 2 12inch kenwood peak power 600 watt magnet 500g (17.6)oz impedence 4 ohm kfc-w300s speakers

It's not bad, but at 400 watts, it's a bit underpowered
It'll be plenty loud, but the amp will distort before the speakers do, particularly if your subs are wired in parallel (as dual-driver boxes are typically wired)

Listen for distortion, and turn it down a bit if the sound gets fuzzy or static-y sounding

To get the most power what is the best way to connect paraelle or

run them straight and dont use the cross over. One speak on right channel and the other on other channel. Then turn up amp settings 7/8 the way up and control the rest from your dvd/cd player. I recommend some monster cable which is very thick. Ground the amp directly to trunk bolts but make sure to scrape the paint off or the connection will be bad. You can also use a cap which will send battery pulses to amp much quicker.

I have a Jensen A600HLX hooked up to Rockford 12 and it keeps getting hot and cutting off. I have it mounted on the top of the box. What is wrong?

Make sure you are using the proper gauge wiring for your amp.

Is the amp set up in bridged mode? What is the impedance (Ohms) of the Rockford Fosgate 12? If the impedance of the speaker is different from the impedance for the amp in bridged mode, it WILL get hot and cut off. Also, if you overdrive the amp, the same will happen.

The amp is stable :
  • 75 watts RMS x 4 channels at 4 ohms
  • 100 watts RMS x 4 channels at 2 ohms
  • 200 watts RMS x 2 channels bridged at 4 ohms
  • 300 peak watts x 2 channels bridged at 4 ohms

  • Also, what model is the subwoofer? What are the specs? Is it single or dual voice coil?

    You can most likely mount a cooling fan on the amp and have it turn on using the remote sensor wire. If the amp still cuts out, you're overdriving it.

    Good luck and keep me informed!

    I turned my car on and when the amp turns on one speaker pushes out and the other pushes in and stay like that and dont produce any sound. i checked the wires and fuses and everything is correct but i cant...

    Hello mikhail_1994,

    I'm assuming that the amp was installed and was working properly.

    It sounds like the output is shorted. The CH450 may be operated as a 2-channel amp or both channels can be bridged for mono powering subs at an impedance of 4ohms or more.

    I'd test the sub voice coils and then test each channel of the amp separately.

    Hope this helps.

    Two terminals? bridging theory?

    Hello again jm129852,

    Having two power and ground terminals allows you to run two smaller wires instead of one big one. It's a convenience. No, you do not have to use them both. They are connected together inside. Yes, you should still use a single fused battery lead. Connect the big wire and fuse holder to the battery and to a distribution block and run the smaller wires from the output side of the distribution block.

    When you connect the outputs of a two channel amp to two separate speakers, each speaker gets the power produced by it's channel only. If you are using only one speaker, and the amp is rated to operate bridged, then the speaker will receive the power from both channels, typically twice as much. You do need to be careful when using bridged mode because many amps will only operate safely at a higher impedance when bridged. For example, when operated with both channels connected to separate speakers (not bridged), it may be stable to 2 ohms. But when you connect both channels together (bridged), it is only stable to 4 ohms. Usually, the specifications will tell you the lowest impedance at which the amp should be operated. The specifications for the current RF Punch 500.2 are like this: 125 watts X 2 at 4 ohms; 250 watts X 2 at 2 ohms; 500 watts X 1 bridged at 4 ohms (4 ohm stable in bridged mode). You would NOT want to connect two 4 ohm subs in parallel to this amp in bridged mode. It would result in a final 2 ohm load and the amp would overheat and fail. One 4 ohm sub would be OK, and it would receive the full 500 watts as stated in the specifications. You could connect four 4 ohm subs, two each in parallel to each channel, and the 2 ohm loads on each channel would be OK. Or you could series two of them together for an 8 ohm load, do the same with the other two, and then parallel the two 8 ohm loads for a final impedance of 4 ohms and connect them into the bridged terminals. With DVC subs the connection possibilities get more complex. There are many good impedance calculators online that can help you determine the best wiring solution for various amp/sub combinations. I like the one above at web site. Rockford-Fosgate also has one which allow you to select the a number of subs (up to 4), their voice coil configuration (single or dual), and the voice coil impedance. The RF calculator then shows you what configurations are available and what your final load impedance will be.

    Hope this helps.

    How do i bridge 3 subs to a 4 channel amp

    My information shows the XM-1652Z as being a 2-channel amp. It will not be stable below 4-ohms in bridged mode. For best power, your subs will need to be 2-ohms with all 3 wired in series. This will present a 6-ohm load to the amp. After wiring the subs in series, connect the positive speaker wire to one channel (+) and the negative speaker wire to the other channel (-). For the 1652Z no other wiring is necessary. For subs you will also want to set the LPF (80Hz) switch to the "ON" position (to the right).

    Keep in mind that the rated output is only 400 watts RMS at 4-ohms in bridged mode. That's kinda wimpy for 3 subs. You would probably obtain better results from two 2-ohm subs, each connected to a separate channel. That way each sub would be getting 200 watts RMS, still low but there's lots of good subs that will sound pretty loud with 150-200 watts

    I have a 4 channel amp

    This amp will not give you 1000 watts of real power. From the specs I've found, it can produce 55w RMS x 4. Bridged, that would be 110w RMS x 2. The most you could get into a dual voice coil woofer would be ~220w RMS.

    Not producing sound

    It sounds like the power supply may have failed. I'm not familiar with that particular Boss amp but many amplifiers will light the power indicator even though the amp isn't operating.

    Have you checked your speakers to see if they're blown?

    Have you checked the wiring to make sure the speakers are still connected to the amp?
