as titled, would I be ok, power wise, running a single SA-10? If I run a single 10, I was looking at getting the D4 then running it parallel to the subwoofer output of an old school Soundstream 705S. Also considering 2 of the SA-8's. I listen to everything, from 50s and 60s to bass CDs and hip-hop.
This would be going into the trunk of a 1965 Chevy Nova.
Also, what kind of box would be best? I dont have access to all these box building programs and am used to the old way of cylinder ports but can easily build vented.
