(upbeat electronic music) - Hey, guys, it's Brayden with Sonic Electronix, and today we're gonna be showing you how to wire these two Dual four ohm subs in series parallel to equal a final impedance of four ohms. So, here we have our NVX VCW dual four ohm subs, which we're gonna be wiring in series parallel. Now you can test the impedance of each coil to see what it rests at, just to verify that it is a four ohm coil prior to wiring, which we're gonna go ahead and do real quick here. Next we wanna go ahead and put our meter setting on the ohm, take our two test leads, and attach it to one of the Voice Coils of the woofer. It does not matter which one you use, positive or negative. Now, make sure the woofer is facing up towards the sky, 'cause if we do press this cone, the impedance will fluctuate up and down. So, once we stop touching the cone we should read a four ohm final impedance.
