Ok so I got 2 of my sa-8's hooked up on a rf bd1000 (on loan) each sub has .8cf per sub after all displacement and I am just not happy the OG plan was to run 4 but based on the output I am getting from the 2 I think I want to just trash the whole idea and start over. So here are my options and what I am looking for is the most output not to worried about sq at this time my front stage takes care of that for me. Amp will stay the same no matter which setup I go with and I have 2k@1ohm on tap and tuning will stay the same also 32hz.
Option 1 - 4 sa-8's each will have about .7cf after all displacement. Will have to use external aero ports.
Option 2 - 2 sa-12's each sub will have about 1.5cf after all displacement. Will have to use external aero ports.
Option 3 - 1 Nightshade 15" sub will have about 3.3cf after all displacement. Will have to use external aero ports.
I may or may not be going with sundown I am just using their subs as an example. So I am not asking if there are better subs out there what I am asking is based just on the size of the drivers which would give me the most output. Setup will be going in the trunk of a Saturn ion and will be used only for a daily system.
