Thats a great price for what seems to be a decent cable. You can cut this wire and get more than one run per spool. You have to measure each speaker run and do the math to see how many spools you will need. One caveat...make sure your runs are continuous so you may have some left over from each spool.

Read my earlier post about the phasing to get the best from your system. Also try moving the speaker around a bit to optimize each speakers response....rule of thumb - generally the closer to the rear wall the better the bass unless their rear ported.
