The power comes on . .but there is no sound coming out of the subs. It was working before, although i think i must have bridged it wrong or something . .because it stopped working . .the power light was going off, then on, then off, . . . .so i disconnected all the wires . . tried it again . .but the power now works . but still no sound. .i'm starting to think maybe it could be internal problem . maybe one of the mosfets, or something . .

Pace posted on Saturday, March 05, 2005 - 01:08 GMT Your subs are dual 4 ohm voice coils so if you want to bridge your 2 channel amplifier to your two subs then wire them parallel, meaning the + to + and - to - ( Do this to both subwoofers), Then run a wire from one positive and one negative on each sub and bring the two positives together and the two negatives together and hook both positives to the far positive connection on your amp and connect both negatives to the other negative on your amp,
This will create a 4 ohm load on your amp.
Although if it's a two channel and you have two subs it's usually pointless to bridge them because if you use one channel per subwoofer its going to be the same as if both subs were bridged. example) 800 watts x 1 bridged power of your amplifie (4 ohms) is the same power as 400 watts x 2 at 2 ohms.
It sounds like the problem is with the amp. try using the other sub in bridged mode and see if it still turns it off. If it still turns off then its definitely the amp. In 2 channel mode you are using each channel at 4 ohms right? and in bridged mode to 1 speaker it should be throwing a ton of power on a 4 ohm load as well,it should work fine bro -its gotta be the amp
Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Dou
.A thumbs up would be greatly appreciated if this answer is helpful to you.
The amp and sub combo should work fine the subs can really take a crapload of power-i have a neighbor thats running 1200 watts rms to each sub in his caddy and OMG- its sick. Your amp should be pushing around 800 watts rms(continous) to the sub which should do very well-my concern with your setup is that the sub is designed for a vented box- you can use any box u want but im just suggesting that you use a good solid vented box with these subs- my other concern with your setup is that having only the single sub if its a dual coil 4ohm + 4ohm coils then you might run into trouble if you dont have it set up right-by that meaning to get all the power handling capability of the sub you would want to use both of the coils right? well to do that you have to either wire the coils in series or wire the coils in parallel right? In series the coils will yield an 8 ohm load to the amp and youll only get about 400 watts from the amp bridged into that 8 ohm load- on the other side of that if you wire the coils in parallel then the cols yield a 2 ohm load and that could cause the amplifier to become unstable and fry its little guts. All of this is assuming that the amp is made to run bridged at 4 ohms- if it is 2 ohm stable in bridged mode than you have nothing to worry about. Now the popping noise- that sounds like its coming from the amp somehow and just feeding through to the sub-like you ive never heard a sub popping unless its bottoming out and you say its not so its gotta be the amp id say-if it were me id check all power connections especially the ground for the amp . It could be that on the heavy bass notes that your amp is not getting enough juice -throw a 3.5 farad capacitor on the power line and see if that helps your system out-
According to the specs for the xo 1945- the output is; 50W x 4 Max Power Output , and I do not see a pre amp output listed. So I think to connect subs, you will need a separate AMP.
The way this works; the rear speaker wires from the xo 1945 hook into the Add-on amp, for example a 4 channel amp. In a 4 channel amp, the rear speakers come off two of the channels of the add-on, and the subs come off the other two channels. There is also the option of bridging two channels for more output power to ONE sub.
You did not mention what size sub(s) you were thinking of adding, but keep in mind that the ox 1945 puts 50 watts MAX per channel. So, if you add two 12" subs and a 1500 watt amp to drive them, your total sound is going to be very uneven.
If you go on line and look up auto audio or amps, you'll get a good idea of all the Sub and amp options that are available.... Hope this helps.
overpowered definitely. when you bridge subs your almost doubling the power. if the subs were set for 2000 then the guy he took them too should have known better or at least turned the power down on the amp.
you may have to send it in or back to the company... being that its one side it could be a blown amp or perhaps a bad speaker on that side ..
hooking up two 6x9s and a sub in bridge mode you could have a wiring problem when i bridge an amp i go from positive of one side and negitive on the other to the same positive and negitive on the sub or box

The sub you want is ONE single 4 ohm voice coil sub that is no higher than 500 watts in power but more than 350 watts. Your amplifier puts out the most power in the bridged state at 4 ohms so this is why you want a single 4 ohm voice coil sub. Also, you don't want to over or under power a sub so you want your sub to match or come close to your rated value of the amp. Good luck
