I have Boss ar2400 4 channel amplifire.. I had connect two 15" kicker subs in bridge circuit. When i run the system it gets overheat in half an hour and goes into the protection mode. How can i solve this...


Problem is one of four things:
  • Impedance (ohm resistance) of the speakers you are using is below the amplifier's rating for operating in bridge mode;
  • You are driving the speakers at a volume exceeding the maximum power output of the amplifier;
  • The gauge of the wires you are using to connect the amplifier to the speakers is too small;
  • The gauge of the power supply wires is too small, and/or you are not using a large enough reserve capacitor at the power input
Possible solutions:
  1. If your Kicker subs are rated at 4 Ohms, and you are using them in monoblock configuration with the speakers wired in parallel (all + terminals to the + bridge output and all - terminals to the - bridge output), try either configuring your bridge circuit in a paired bridge, where a pair of amplifier outputs are bridged, each bridged pair driving a single speaker; or if your Kicker subs are rated at 2 Ohms, use a monoblock bridge driving the speakers in series (+ bridge output to + of one speaker, - of that speaker connected to the + of the other speaker, and = of that speaker connected to - of the bridge output);
  2. Turn the amplifier output down (but this is likely NOT the issue)
  3. Use speaker wire that is no smaller than 8 gauge for your application. 4 or 2 gauge wire would be slightly better but not worth the additional expense;
  4. Your power supply wire should be equal in size or larger than your speaker connector wire. Use no smaller than 8 gauge for your application. Also, use a capacitor no smaller than 2 Farads wired across the power supply input to the amplifier to compensate for pulse surges and car power dips. For your application a large capacitor will work better than an auxiliary battery or gel cell.

If i hook up for 2 ohm do i use one speaker wire off amp bridged


Just use both speaker outputs, no need to bridge them,

How do you bridge the jl audio 450/4


Nice amplifier. However it is best suited for speakers and not for sub woofers. Connect the plus (+) from speaker output 1 and the minus (-) from speaker output 2. Connect the plus (+) from speaker output 3 and the minus (-) from speaker output 4. Now the amplifier is in bridge mode, which will give you 300 WATT RMS at 4 OHM load. If you are bridging the amplifier to run sub woofers then do not forget to set the X- Over to LPF on the channels that you are planning to bridge. Whatever you do, make sure that the load you are asking the amplifier to play is no lower than 4 OHM. Playing this amplifier in bridged mode lower than 4 OHM is a recipe for trouble.

Can you bridge the vega 124 or just use 1 channel on a punch 400x4


Here are the important concerns:
The power rating of the speaker(400W) should be 25% HIGHER than the maximum output of the amplifier BRIDGED. (Amp bridged output 200W - OK!)
The amplifier will get twice as warm running the speaker when loud.
The impedance of the speaker can be no less than 4 ohms when the amplifier is bridged. (Yes, this speaker is 4 ohms - OK!)
Your punch amp is capable of running TWO Cerwin Vega 124s, bridged.

It has an A and B channel for spkrs and i have one spkr bridged. do i split the neg to side a and pos to side b or just use one of the channels?


Could you elaborate on how the speaker is bridged?

I think you want to hook up a single speaker to a stereo speaker output.

In this case, you would strap (bridge?) the right and left speaker terminals by running a short wire from A right negative to A left negative. Then strap A right positive to A left positive -- this will give you mono output on either of the right or left speaker terminals -- connect your speaker to either one of these.

Do you know what the ohm rating is for the speaker outs on the amp and also the speaker itself?

How would i conect a ep2500 amp two 2 subs @ 4 ohms, or 8ohms


hey" i got 2 behringer 2500 amps and i have 2 peavey speaker that are 4 ohms 2000 watts eachand want to mono the amp separte,and i want to run 1 amp to each speaker so can you help me?

Bridging issues


There's no signal on the L- and R+ terminals.

If you're going to bridge both speakers on the amp, each speaker must have an impedance of 8 ohms (or more). If you're unsure of the impedance of the speakers, connect one speaker to each channel.

Let me know if you have any other questions.

On lucent amps you sometimes have to bridge two terminals together to make it work. i need to know what two need to be bridged.


I'm not sure if Lucent has a special bridging procedure, but on most if not all other amps, when you bridge you DON'T connect two terminals together. What you do is instead of using the plus and minus terminals on one channel to one speaker and the other +/- terminals to the other speaker, you will instead use the plus (+) terminal from one channel and the minus (-) terminal from the other channel to drive one speaker and the remaining + and - terminals remain unconnected. Be sure you use the + and - terminals that are marked for bridging. Please note, that when you bridge that your speaker load DOUBLES to EACH channel. In other words, what your amp saw as a 4 ohm speaker going to one channel alone, it now sees as a 2 ohm speaker on each channel when bridged. Be sure you know what you are doing before you bridge and fry your amp. In my experience, if after bridging your amp works fine for about a month and then fries then you bridged wrong and ended up with the wrong speaker load on each of the bridged channels. Be careful. Amps cost a lot to repair. Good luck.

Hi monmax,
I hope you are aware that in bridged mode your amp will become monaural (single channel, double power). If you still wish to bridge it:
Switch of power.
Set mode switch behind amp to "bridge" position.
Connect speaker positive to CH1+ve terminal of amp output and connect speaker negative to CH2 +ve terminal.
Be aware that now, in bridged mode your amps output power delivery is 1100 watts for a 4 ohm speaker and 900 watts for an 8 ohm speaker. Make sure your speaker can handle that.
Peace
Jango.
