  1. 10 inch Sub Box

    Posted by Joe on 27th Mar 2015

    Waited longer than expected to receive my sub box due to high demand but when I received it I was very pleased. Good craftsmanship and quality. I installed a Kicker 10 CompVR DVC and it fits perfectly in the box and the box fits good under the seat. Great job!!

We build each sub box and ship within 3-10 business days excluding weekends.
