Don't buy 12 Gauge speaker wires it won't even fit into the holes of the connectors on the amp itself. 12 gauge is just too thick and it certainly won't fit into the radio shack 1/8" mono connectors.
just trying to save you some trouble cuz I bought 12 gauges wires and came home to find out the wires are way way too thick what a disappointment I felt like i wasted a bunch of cash. I then trimed downt eh 12 gauge and soldred up the wires to the radioshack mono plugs without the protect casing and 1 minute later the weight of the 12gauge broke the connectors.
I'm going to try some cat5e cables, that my friend gave me, as speaker wires for the klipschs. I'm just going to straight up connected them as they are, the whites and colors seperated of course. Using another set of radioshack mono connectors
if you're lookling into other tweaks, you could go out and buy some polyfil from walmart or a fabric store for 2-3 bucks and open up your speakrs take out the wedge foam thingy they put in there and stuff it with polyfil. It should improvement the sound and also increase the volume. I no longer feel like the subwoofer is overpowering my sats anymore at the default sub volume.
Also you could try to stuff your subwoofer but I really really don't think it does much of anything I tried it and I couldn't tell a difference. Maybe because its ported? I dunno.
Another thing you might want to do is take off the speaker grilles Defintely helped the sound, but you take a risk of damaging the speaker cones so if you got pets, cats, kids running or the speakers aren't set on a stable surface I would be wary of taking off the speaker grilles.
Thats pretty much all i've done to my speakers less the cat5e speaker cables. I took a look at the control pod and found two opamps it started with NE and it had a couple of number 5's in it but I can't remember.... but there was a mess of capacitors soldered onto it right below the opamps on the otherside of the pcb it was a mess...
but anyways goodluck and if you find out some more tweaks please post em! so we all can benfit
