Sunfire Subwoofer 110 Noise on input plugin
A few more questions-
Does the sub hum without anything plugged into it except for power? If it makes a real loud hum almost a squeal then I think the rca cable between the receiver and the sub is dead shorted and needs to be replaced. If it's more of a low level hum, then it's a ground hum caused by many things, ie........the receiver and the sub being on different power circuits in the house.......sometimes diconnecting the cable tv feed as it enters the room while the sub is connected and humming to see if it stops........the easy fix sometimes is using a 3 to 2 prong ac adapter but lifting the ground on such a powerful amp could be a fire hazard.
Amplification
You need to now the RMS for a true capacity of your speakers and your amp.
I would say you are OK, with a margin, but if you turn the amp to max and blow the speakers, please dont call me.
How a hook up my subwoofer with the pc?
Hello
You need to build or buy a certian cable. The cable goes from RCA to mini jack. You plug the mini jack into your computer and the RCA into the input of the sub. I really hope this can help.
Best regards
How do i bi amp sx 1250 to get both channels of
you are actually not bi-amping the unit, you are bridging the amp. this really only works as long as all channels produce equal power. next the bad news is that typically home stereo amps are not wired internally to bridge channels.
bi-amping a speaker refers to connecting on channel to the highs and on channel to the lows. the receiver would need to be be able to process the outputs via a crossover network to split the frequency range in half so the appropriate frequencies went to the correct speaker.
Sub doesnt do anything while plugged in ( Sunfire mk II)
Some subwoofers can sense the signal on their input and will only start when there's enough signal for long enough time for them to turn on the amp.
Try seting the "subwoofer signal out" on your reciever a bit higher, see if it does the trick, if not, try it with some other source (e.g. an mp3 or CD/DVD player) plugged directly into the subwoofer. If it still doesn't work, there's some other problem with your sub (bad connection inside sub, sub amplifier problems, maybe there's another fuse for the speaker itself, try to check it out).
If it works well with an alternate signal source, the problem might be either in reciever or the signal cable that you use, but could also be something else.
good luck

Has light but no sound
The first thing to always check first is the fuse. This will probably involve some disassembly but it is alwayst the cheapest fix and a constant issue.
Snapping sound
send this baby to the manufacturer, great service at fair prices...they will often repair for free
Behringer ep2500 amplifier
Yes you can,,,,,BUT the output labelling on the AMP will tell you where you can connect the 4ohms or the 8ohms....please read these labels and connect the 4ohm speakers to the 4ohm terminals, and the 8ohms to the 8ohms terminals...
If you intend to connect the 4ohm and the 8ohm speakers in parallel then the output impedance terminals you use should be the 4ohm ones.
If there is no labelling showing any 4ohm output terminals then its best if you dont use the 4ohm speakers at all....just connect the 8ohm to the 8ohm terminals...you dont mention any crossover networks inside the speaker boxes or if you have tweeter speakers... so just stick to the basics above at present....

No Power
hiya
if u change the fuse inside the actual sub shud power up ok

Microphone troubles
Contact the Sunfire tech folks . They've responded quickly for me.
Probably not in the power amp. It's whatever youre plugging the MIC into.
