Great fitment for my 4Runners oem jbl subwoofer

The following review is for CWRT82, which is a part of the bundle you are viewing.

Bought to replace my oem jbl synthesis subwoofer, decent fitment slightly smaller so it barely fit, great power handling great blending to the rest of the system, going in I knew the oem jbl wasn’t going to be up to snuff so I added a cheap aftermarket class d amp to power it, sounds soo good with the added lower end into the mix I’m upgrading the rest of the speakers and just tapping into the oem jbl output wires into a line output driver unit for aftermarket amps, this is to keep most of the oem tuning which i prefer just needs to be louder lol
