do you need a separate sub amp to work this? If so what size?

No, just running a receiver "Onkyo" model 616. I have 2 separate sub amps for the front and rear sub woofers

No need for a subwoofer. I run mine through a sony receiver and I get good sound.

You just need your normal surround amp no separate amp required p.s. they sound awesome

I wouldn't set it up like that...I would definitely get 1 amp to run the speakers, and 1 to run the sub. I purchased a 1000w amp for the subs, and this amp for the 4 speakers. Works great.JL W6 12V24x Infinity Kappa Perfect 6 1/2

Yes you can use just a single sub cable and just use the L plug, thats what i do.

Yes it will work but your going to have too much power. Your probably going to have to turn the gain on the amp all the way down. Are you going to run one or two subs. I would run two at 4 ohms if you have a choice.

Why would you want to do that? Look into the BIC subs for home stereos. I have one and it is powerful and it has a amp connected to it. Even if you hook it up to a home stereo, this sub still needs lots of power.

I smaller amp one with about 500-700 watts rms. this sub I believe can not handle the told watts.

You need to purchase a separate amp for your 6" speakers. I have two small amps driving 6 speakers, & the sub has its own internal amp. Even if you could use the amp to power additional speakers. You wouldn't want to do that.

Sub is active and does not need an amp but the remaining speakers will need a separate amp.

You do not need to add a sub amp for this unit. It is non powered and you simply run the speaker wires to the sub and then from the sub to the speakers. This system has a built in cross over that takes the low signal out and sends the mids and highs to your speakers. Its very very simple to install and sounds great! You won't be disappointed.

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

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. Hope That makes sense.

Yes you will need a separate amp. No these do not connect directly to a computer.

You need a receiver. The subwoofer is passive so it does not require an amp. I returned mine however as the sound was poor

The sub out is only preamp out. You will need a powered sub. I recommend about a 250 watt, 12" sub. My sub is a Polkaudio 12" and it blows the walls down. I think I paid about $299 for it.

An active subwoofer would be best. With a passive subwoofer you will need a separate amp to power it.DJ FLASH

The amp will work, I used a 3000 watt crunch amp and the subs took every bit of that amp.

Yes because your sub is powered. It's better if your source has a separate sub, otherwise use the right channel.
