If you're talking the 2 wires with rounded ends that you plug into amps / eqs / tvs, then yeah, that's a hella lot to me. 18 guage wire plus DIY RCA kits are in my car, ends up being about $14 for a 20 foot cord + some solder.
Of course, you're taking a $3000 system. Mine is... not... $3000. In fact, all said and done, I'll be spending hardly over a grand on my first and second setups combined. In your case, hell yeah it'd be worth it.
