I ordered the JVC DS-TP350 HTIAB and am kinda having lots of trouble setting it up. For one thing, the front and rear speakers all 4 look exactly the same. Does it matter where i place them? Do they all hold the same power each? Can i just grab two, hook em up to the front, and put the other two in the rear? Also, i am either missing a digital coaxial cable or a subwoofer cable. The system CAME with a black cable with an RCA jackand these lititle ridges that kinda wrap around the jack. Is this a coaxial cable or a subwoofer cable? Also, when plugging the speaker wire into the reciver and speakers, does it have to be pushed fully in because these loose strands are driving me insane. Thanks.
