speaker/receiver question

so i just bought a 800 watt 7 channel receiver for my home theater because the one that came with the speakers died. i have 5 surround sound speakers that i wired into 5 of the slots. i also have a sub woofer that i want to hook up. the wires out of the sub are 115x2 (4 wires, pos. x2 and neg. x2). here's my issue: the receiver's connectors for the sub are audio jack slots and my sub doesnt have those, just the wires.

1-do they make and adaptor for this. i.e. male audio jack with wired ends? if so, do they work well?
OR
2- can i wire the sub into the 2 remaining surround slots? pos and neg in each slot both powering the sub? not sure if that would work tho, im thinking the surround slots only output high frequency and im not sure i should wire 2 channels into one sub.
OR
3-can i splice the pos and neg leads from the sub and connect them to 1 of the 2 remaining channels? not sure if this would give the sub enough power because each channel is only 115 and the sub needs more than that.

any help/advise would be appreciated, thanks

Just solder and wrap two RCA jacks to the Subs wiring and plug

+1
and just make sure both wires don't touch eachother

huh? each jack is going to get a + and - yes? what do you mean by 2 not touching each other.

agreed if they touched it would be pretty gay

yea bro. + and - shouldn't gay. i mean touch.

The answer is actually this: The sub outs are RCA jacks, meaning they are line level and not output transformer impedance.

They are line level because they are supposed to connect to a powered Subwoofer with its own amp.

The rest of the receiver outs are speaker wire connectors and 115 watts per channel times 7.

Splicing will not work. The Sub needs its own amp.

Doesnt your sub have a LFE jack and your receiver have a single sub insert??? If they do, ignore all that other shit and plug a speaker cord into those. It would probably help if you posted what sub and receiver you have. Soldering shit is fine, but seems kinda gay to have to do. If all else fails you could put banana plugs on the ends that need jacks.

those F3's sound better as fronts then those sonys dont they?

chem...any decent audio shop will make these up for you/ jack at one end (lol) and bare ends at the other (x2 lol) cost you from around a fiver to mayve twente bucks depending on quality of cable s'pose.

i have the same setup with my sub to receiver its no big deal...nice setup btw!

What is an audio shop!?

eh?

Make sure you don't hook the polarities up wrong (+ to -) otherwise the sub will be out of phase.
