MTX 502 bridged into 2 ohm load. Power system up seems a little weaker than normal. Unhook left rca wire...no change in output. Plug left rca back in unhook right.. silence turn gains up no help... replaced rca wires...no help. Looked carefully over circut board for anything unuasual with no results. Also the left rca output is dead. Assumeing this is a simple problem early in the amplifieing process. Any help with maybe a scematics diagram??

Re: MTX 502 2 chanel amp Pre amp problem?
Unless your amp is 1 (one) ohm stable then you may have fried it. When you attach a 2 ohm load across a bridged amp then you have effectivly placed each output channel on a 1 ohm load. Not a good thing in most cases. Try hooking up ONE speaker on one channel and one input to that one channel one at a time. Then switch the speaker/input to the other channel and see if you can get either or both channels to work independently. Needless to say you must turn the amp off before you make ANY change in the wiring.

You cant bridge it to the MONO AMP . You can only bridge subs & speakers to 2 CH & 4 CH AMPS that are bridgeable. Because if it appears that there is 2 channels on a Mono amp its so its convenient for you to hook up 2 4ohm subs to it easily But both channels are actually connect internally together in parallel inside the amp unlike a 2 channel they are separate.
So just connect your mtx 9500 to a plus and a minus and doesnt matter which since all the + terminals of are connected together and - are connected together already.
Whats important is on the side of the sub/box it reads 2 ohms. The lower the ohms the more power the Mono amp will put out. Mono amps are designed to handle 2ohm loads.
If it reads 4ohms The MONO amp is the wrong amp to use cause the power will be weaker. So if you have a 1000 Watt Mono amp at 4ohms the sub will only get 500 WATTS Max while a 2 ohm will get the full 1000 Watts.
If it reads 4 ohms connect it to a 2CHANNEL AMP and BRIDGE IT (connect + of the sub to 1st channels positive of the amp then connect - of the sub to 2nd channels negative of the amp) . The power will be doubled when you bridge it on a 2 channel amp. NOW if it was a 2 ohm sub and you bridged it to the 2 channel amp it will fry the subs and ruin the amp. 2 CHANNELS CANT TAKE A 2OHM LOAD BRIDGED OK.
Is there a option on the chanels that say ''Bridged''? If so, you can hook the subs up in parellel or series to get different ohm loads. Usually the lower ohms, the more power amp puts out. Those subs can handle 225 watts RMS whitch means the power it can handle constantly. If the amp gives more than 225 watts RMs, you could be at risk of blowing the sub. If you could give me the model # of the amp, I can be of more help.
A 4 ohm DVC sub can be wired in series like you described for an 8 ohm load or the voice coils can be wired in parallel for a 2 ohm load.
If your 2-channel amp isn't stable down to 2 ohms when the channels are bridged (most 2-channel amps are only stable to 4 ohms when bridged), you do not want the voice coils paralleled. The amp will overheat, go into protection mode, and eventually fail completely. A sub with 2 ohm voice coils would be a better fit. That way, you could series the coils for a 4 ohm load and the amp would operate OK with the channels bridged into that load.
But anyway, for the best power from THAT amp to THAT sub, your best wiring solution would be to wire each voice coil to a separate channel. The problem with that is that the signal to each coil needs to be EXACTLY the same or you will have one coil trying to move the cone out while the other one tries to move it in. You can closely approximate identical signals on the output side by using the same input to both channels. Do this by using only one RCA connection (either right or left channel) from your head unit and split it with a "Y" cable.
The 2 ohm stable rating on the amp is PER channel meaning that you could effectively hook up a 2 ohm speaker or a 2 ohm load to each channel without the amp getting f"d up-butin bridged mode it will only be 4 ohm stable. to achieve a 4 ohm load with your sub the type x wire the coils in series that will get you at 4 ohms to run in bridged mono .But you will get the exact same amount of power if you wire each coil to one channel of the amp as bridged mono sees the sum of your 2 ohm channels combined-Hope that helps.
For maximum power, you'll need to wire the subs so that they present a 2 ohm load to the sub outputs on your amp. That will give you the full 420 watts RMS the amp is rated for. Likewise, you,ll want the run the front 4-channels at 2 ohms. Run separately, they produce 85 Watts times 4 channels, or if bridged, 130 watts times 2-channels. But if you run fronts at 4 ohms, they only produce 70 watts times 4 channels and your sub output at 4 ohms drops to 210 watts.
A 2 ohm stable amp should be able to be bridged to 1 ohm (consult owner's manual for bridgability), but a 4 ohm speaker is a 4 ohm speaker and would need to be parallelled with another 4 ohm speaker to provide a 2 ohm load.
yes it should work fine i would bridge them up to 4 ohms each speaker then bridge them back bye conectin them on the amp by puting the red with the red and puting the black with the black if the amp only has 1 chanel then put both speakers red on the same positive on the amp and same with the negative now to bring the ohms up to 4 ohms conect the solid red to the black with dot with a short wire ok then the ones that are not run together will go to the amp giving offf 4 ohms and with the 2 speakers bridged together thay will reduce to 2 ohms witch means that eatch speaker will get about 600 wats of rms from the amp
ASSUMING that the amp is OK with a 2ohm load then you "set it up" by the configuration of the speakers you use. Two 4 ohm speakers if parallel will give you a 2 ohm load. However, if you are bridging the ouputs then a single 4 ohm speaker bridged between the two outputs will put a 2 ohm load on each channel. Be very careful if you are bridging the outputs that you know what you are doing. On average, when bridged wrong (too much load) the amp will last about one month before it fries. Get some help if you are bridging. Be sure not sorry.
