Would it be possible to use this amp and a low-pass filter, to drive only a subwoofer? How about doubling the subwoofer wires to both outputs?

The built in crossover is complete junk and doesn't work and the sub distorts when you turn up the sub volume even a little past the point you can hear it. Stay away and buy something else.

I have a Polk audio sub, and I barely have the sub volume on. With an unused pair of Bose surround sound speakers, I use this for my computer sound system and it is almost better than my Kenwood receiver with Bose speaker system.

Yes, you can use it for a Sub only. It can handle two subs as it is. Or one DVC sub, if you like. I don't think I would try bridging the outputs. But, if you can figure out how to do that, without killing the amp, let me know.

It already has a low-pass filter, a separate sub volume control, and a separate x-over control (50 hz to 200 hz). Also there are 8 speaker outputs. The top four are left and right (2-each) and the bottom four are 4 wires to the subwoofer (2 + and 2 -). I imagine you could use it for a subwoofer only - just don't use the left and right channels...

Sure run the front 2 channels on HP or High Pass and bridge the rear and switch to LP or low pass. You have separate switches for the front and rear for or for you subwoofer. Try and get a dual voice coil sub to being the impedence down to 2 Ohms equals more power. I also recommend a 2 Farad Capacitor from VM Audio for this and remote bass knob.

I would.think so seeing as it has a built.in crossover. But i would talk to someone from best buy, or an audio store.to make sure before.purchasing. I only have a sub, and my factory speaker hooked up thru this amp. So I am only taking up two channels. I will say, it's a beast of an amp, and if it does what you are looking for, its worth every penny. Hope I have been of some help

I would just run the 4 channels to 4 speakers. Then use the rca jack to the amp to run just the subwoofer.

Yes, you can connect up to 1 subwoofer to this receiver. Keep in mind that it must be a powered subwoofer with an RCA style plug. "Subwoofers," or bass speakers, that use speaker wire will NOT connect to this receiver.

This amp only pushes 250 watts with a slightly lower RMS. You should consult your manual for the sub to see what RMS it should have. if you use a lower RMS then recomended it will reduce the life of both the sub and amp. I did not know that when I bought mine I'm running a w0 which is slightly underpowered by this mono block. good luck and I hope your system turns out great!

I've been happy with wiring the second inputs separately on the big L and R speakers and using that for the low end, but I'm also not a major bass-head. I'd suggest trying that first and then if you feel you need to add a sub, do it.

seeing as two other people already answeredhere http://lmgtfy.com/?q=why+you+need+an+amp+to+power+a+subwoofersimply put you need an amp to power a subwoofer otherwise it wont work

I suppose you could use the passive crossover The idea is that these have sufficient power to drive them and most amps don't have a dedicated sub-woofer output so you are robbing power from elsewhere to drive them you can connect them in parallel or direct to adjust the impedance as you can do with a normal sub I drive mine with a high pass filtered 4 channel amp I have one under each seat in the car I also made a piece of plywood quarter inch thick to mount them to the board is silicone'd and screwed to the bases of the seats to stop rattles works really well

Robby I wouldn't suggest it as this amp is specifically designed to drive sub woofers. It would work if you were going to build a band pass enclosure and use a couple 6.5" drivers for your deep bass frequencies.

Q: can you use this to power 4 6x9 speakers (150rms each at 4ohm) And how would you wire a high level imput into this amp? (stock head unit because they dont make an aftermarket one)A: You can buy the speaker line to RCA adapter to feed your speaker lines into the amp. I used an Audiocontrol LC6i in my setup but not necessary unless you want to add subwoofer and amps.I have a small amp for my speakers and one amp for this sub. 2ohms is how the shop I went to set it up. The amp I got was like $65 and it works great. I've had both for about 1.5-2 years now

Your subwoofer out probably needs to go out to the amp. At the subwoofer out from the amp, is where you can split the signal and send it to both subs. That's what I would do.

This mono amp is designed to be used with a "passive", (non-powered) sub woofer. If your subwoofer has a power cord, then it is "active" , meaning it has an amplifier built into it. In this case you don't need the separate mono amp. Simply run an rca cable from your sub-out on your receiver to the woofer.

The high level outputs are just a pass-through from whatever source you're using to power the main or satellite speakers. The "crossover" only controls the max frequencies handled by the subwoofer (it's really a low-pass filter for the sub) and doesn't roll off the low end to the high level outputs.

If your amp has a 2 ohm output impedance, it will drive 4 ohm speakers, but you won't be able to attain full dynamic range. I believe this sub comes in a 2 ohm version, just buy that one instead. Or buy 2 4 ohm subs and wire in parallel.

you probably needa Y jack to do that and they sell them all over. I would not try that tho until I contacted the manufacturer to see if that can be done. If they are both powered by amps then they may conflict with each other. Only a manufacturer can tell you that. A Y jack would work but you have to make sure your impedance levels match. I would contact the manufacturer to be safe. I would hate to see you blow the subwoofer out.

You will need two amps to do that. One to drive the sub and one to drive the full range stereo. This unit has outputs for sub and another set for full range. You could also use one 3 channel amp instead of two amps. HopeThat makes sense.
