Thanks to everyone for posting their thoughts. Mine should be here tomorrow. I will probably install it as a short term solution to add some more bass. I know I will eventually go with the JL Audio Stealth box. Leaning towards doing a similar build as we did in our daughters Jeep.
For $360 shipped for the subs, box and amp I went a head and ordered. Will see how it compares to the custom JL Audio system in our JL Wrangler and the custom Alpine system in our JKU.
One month old. We think we want to go with the Bestop sunrider for hardtop instead so would consider a trade plus cash or $1,500 for the top. Pick up in Waxhaw NC.
