which Sundown Audio with 400 watts from 705S?

[F16Fxer4real]

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.

Are you really set on using that amp? You will probably wish you had more power sooner than later. For me anyways, with 500w right now, that's the least I would go.

thats what I have to use. Either that one or a 644S which has a little more power. Im wanting to use the 705S though so I can install front and rear speakers as well
How are the lower models of Sundown Audio?

Or, maybe I need to look another direction. JL audio?
