Nice work! So you just tapped into the OEM wiring of the JBL system for the amp and speakers? I have JBL too and have read others ran new wiring to bypass the JBL wires completely (im trying to avoid this).
Sweet rig! Definitely an inspiration for me, I just picked up my 4runner several weeks ago. I also live in Tampa! Would love to tag along with ya'll at the trails one day as I would like to go with an experienced group!
