Located just beneath the doors, the Mod-Pods throw unobstructed sound toward the driver and passenger. They sound great with the doors on and help hide road noise when the doors are off. They make use of otherwise wasted space and are designed to fit snugly against the sidewalls. Mod Pods will fit Wrangler TJ, Wrangler Unlimited, YJ, CJ7 and CJ5.Constructed of thick plastic and boasting a textured finish, Mod Pods can withstand years of abuse. Mod-Pods have pre-cut holes to accept 5.25" speakers, the pods are available empty so you can add your own favorite speakers, and are also offered with Kicker 5.25" car audio speakers included. Mod Pods have hidden wire-lead holes so the speaker wires easily conceal beneath the carpet as they are run up to the radio. Directions, poly-fill and mounting hardware included. In Jeep Wrangler TJs and Unlimited (1997-2006) each Mod-Pod is secured with two self-drill hex-head screws. Each pod has small, pre-drilled holes for precise and correct attachment in these models, utilizing the hollow area in the side-body of the Jeep just in front of the doors, down low by the floor. In CJs & YJs (1955-1995) the best (and easiest) way to install Mod Pods is to apply Lock-Tite Power Grab construction adhesive caulk to the back of the pods and set them to the sidewall of the vehicle, letting the bond set & dry overnight. It is available at your local hardware store, costs just a few dollars for a tube, is exceptional in its bonding abilities, and will hold the pods in place firmly. (All installation methods are covered in the Install Instructions). CJ & YJ owners have a foot activated parking brake that will not interfere with your driver side pod.
