Well, I finally had a chance to lay my hands on an OEM Kicker dual subwoofer box...
If you purchase a used box, without a harness, I can now provide you with a fully plug and play integration harness that mounts to the vehicle the same way the OEM one does
So, if you want to upgrade your bass, take a look around for one of these cool OEM Kicker boxes. They sell for around $200, used, as compared to around $800, new!!!
