Quick question...
I'm finishing up a new box and this is my first time using stainless bolts/fasteners for terminals. Sub has dual 2 ohm voice coil and I've got one wire per sub terminal (correct terminology?)...so 4 bolts total.
My concern is that when I check the resistance from one end of a wire, through the bolt and to the other end, my dmm is reading 0.5 ohms. So with all 4 connected, am I basically adding 2 ohms to the final load? Seems like a lot to me....
Also, if this is the case, do I account for this added resistance when setting my gain using the square root of watts x ohms for voltage?
Thanks for any insight and I don't know if it's needed info, but just incase it's a 12" Sundown Z4 D2, 8g wire and 5/16" x 1.25" stainless steel bolts with flat washers and nylon lock nuts.
