Could have a better way to decide which wire to use as positive or negative. Only has spaced print on one wire.

Box sounds great. Only problem is the trim ring on the Hifonics subs wouldn't fit without a little grinding.

Good value

The following review is for BBSW127, which is a part of the bundle you are viewing.

It’s listed as (cca) which is copper clad aluminum wire and is cheap and doesn’t hold up good to high wattage. Aluminum isn’t the best audio wire, but it is copper clad and electric signals travel on the outside of the wire and that’s where a multi strand wire would come in handy. I think it’s a judgment call, but I wouldn’t buy it.
