Speaker Box Inquiry

I own 2 each of Planet Audio TQ693 and TQ522 speakers. The car that they were going in became totaled, so I would like to transform them into tailgating speakers. That being said, they would be run by an Alpine CDA-7875 radio powered with an external car battery. My plan was to have 2 speaker boxes, each with 1 TQ693 and 1 TQ522. What should the dimensions of the box be and how should they be built to attain the highest possible sound quality? This is the first time that I have done something like this, but I know the set up works as I have used it previously with store bought speakers. Unfortunately, these store bought speakers are more than 10 years old and don't function very well anymore. All suggestions are welcome, Thanks

Thanks, Bill. I contacted Planet Audio again to request the information, but i have yet to hear back from them.

where's the fun in that?
