I think this site should be a sticky... very very helpful for anyone trying to build their own speaker box that doesn't want to do a bunch of math. like me

There is SO MUCH info on that sight......That's where I got my basics on relays.
There is a ton of refeance to BCAE, on the 12volt.com
Anyone here on this site doing ANY audio, or security should read that before posting here.

Littlehag: good call on the "sticky"

 

+1 to sticky

 

Just thought i'd be helpful and share.
