This past Christmas, I got a new Kenwood head unit for my Jeep. It was long overdue since my 15 year old Alpine head unit was getting tard. So, I decided to upgrade my stereo system a bit. Most of the components I had in the Jeep were old tech audio, but worked fine for my tastes. I had two very large amps mounted under the driver seat, one running a subwoofer, and the other boosting power to the dash and pod speakers. I decided it was time to simplify. My old setup.... I upgraded the speakers several years ago, and they still sounded fine, so I left them alone. I installed 5.25" coaxials in the dash with the adapter brackets, and 6.5" coaxials in the pods... I fabbed a custom enclosure in the center console for a slim line 8" subwoofer using the existing console storage enclosure(didn't have the factory sub option).
