Sub speaker level inputs & bi wire mains

Bluto

I am waiting on the the last piece of my new system.

Jolida 202A
Polk RTi A5s
Polk DSW Pro 600 sub

I thought I would bi wire but don't know if it will work. The Jolida has no line outs so I have to use the speaker outs from the amp to the speaker level inputs on the sub. Can I bi wire from the speaker outs on the sub to the RTi A5s or am I wasting my time? Thougt I would use 12 guage wire from the amp to the sub and 14 guage from the sub to the mid woofers & 16 or 18 guage from the sub to the tweeters? Will this work or should I just use single wire?

Thanks

I had the same problem with a pre of mine, and thought about using y-splitter/cables on the preouts but I was worried I'd hear a loss in sound quality just by using the splitter between my IC's.

I wouldn't bi-wire the speakers really, as many do not hear a difference if it's all coming from the same amp. Others do hear a difference, but it's not as significant as it's hyped up to be. Trust your ears, I'm not telling you that you won't hear a difference...just saying that most people don't.

As for hooking your sub up via speaker outs on your amp, I ran some BJC banana plugs with monoprice speaker wire to the subwoofer while connecting my MIT's bananas directly over the BJC banana's so I'm able to run my speakers just as well. If I confused you, I'll link a pic of the BJC banana's, I put the speaker wire inside the "side hole" as opposed to the rear where you would normally run a speaker wire but another banana plug fits inside perfectly. Hope this helps!

Here's the 'hole' I was talking about.

The wire sits firmly in there, and tightened down properly I can't pull it out for the life of me so I know it's fine where it is. Underneath, the opening is the perfect width for another plug.

Bi-wiring couldn't be any less necessary. The only thing bi-wiring accomplishes is moving the jumper that currently exists on the back of your speaker to the speaker level outputs of your amplifier (or subwoofer in this case).

This of course is assuming your speaker cable can carry the current that your 202A provides, which i think you'd have trouble finding anyone to argue that 12 Ga wire couldn't handle that task.
