Bumping up SPL with 2 SA 12s

[brafferty]

I'd say get access to an oscope and actually set your music to its proper point. I'm pretty sure you are undergained. Another thing you can do is invert the subs to gain some airspace.

invert the subs? and you saying that its probably undergained made me feel so much better ahha!

Dont go out there and cranking the gains blindly though... Definitely invest in an oscope if you can. OR use a piezo tweeter.



Inverting is turning the sub around so its @ss is sticking outwards. Benefits is, better cooling, you will smell coils a lot faster when really pushing them, along with a few cubic feet airspace gained for your enclosure specs which might affect output (positively or negatively would be subjected to experimentation)

its not called down firing. Thats when the sub and port faces the floor of the car. Its always been inverted mount.

I may have missed this, but you have 12.5 inches of port area for 2 SA-12s? That's not nearly enough, that's not even enough port area for one SA.
