Installing the WK-4S/ACK1 on JBL Subwoofers (SRX, VRX, STX)

In this video, I&explain how to attach the JBL Caster Kits (WK4, WK-4S, or ACK1) onto the JBL subwoofers such as the SRX718S, VRX918S, VRX918SP, SRX818s, SRX818SP, SRX828S, SRX828SP, STX828S, SRX918S, or SRX928S. For the WK4/WK4S used with the SRX700, SRX800 or VRX900 series subs, a 1/2" Socket Wrench will help. For the SRX900 subs, you will need an 8mm hex key to tighten the screws on the casters.
