I'm running wire to two rock speakers and will be using one underground PVC electrical conduit to carry two separate 2 conductor cables. The conduit run will leave the crawlspace of the home with an LB, down to a sweep fitting underground, then straight to the first speaker and coming up with another sweep into the cabinet of the first speaker. My question is, can this conduit penetrate the bottom of the rock cabinet? Or, should it come up out of the ground into a watertight JB? I was thinking of using the first speaker's cabinet as a JB, which would take the conduit down to another sweep, then straight to the second speaker and up again with another sweep into the speaker cabinet.
The second speaker is about 20 feet away.
