Easiest JL speaker upgrade that makes a noticeable improvement...upgrade your 2.5" factory dash or soundbar speakers to these 2 month old Kicker 3.5" (model # 77KICK25AB) plug and play speakers(great condition-see picture). No wiring work required as the harness perfectly fits the factory harness. Installing these takes about 10 minutes...just pop off the little plastic speaker grill and replace. I bought these new for $55 and am selling due to upgrading further to component speakers. Paypal $40 OBO and I'll ship to you.
