Two SA 12's or a single x15?


Recommended Posts

Right now I have a single Sa12 in a 2 cube box ported at 32hz with 31.25in^2 of port area. Running on 1250w at 1 ohm from a power acoustik BAMF amp.

The plan is to either upgrade to a single x15 in a 4 cube box tuned to 32hz or add another sa12 in a 5 cube box tuned to 34hz.

Either case my amp will get changed out to a audiopipe 1800.1.

The system is in a 2014 chevy cruze with stock electrical.

Which setup would be louder?

If the box is built correctly, I believe the X could get louder... however two SA-12s would sound soooo much better doing it.

But, if you're over powering the SA-12s... then they would be louder than just the RMS on an X.

Also, 1800watts on stock electrical? >___>

Well I listen to a lot of rap and decaf stuff so I was thinking the 2 12's would be a better option. I also thought they would have more surface area so they would be louder. But I don't know if that's exactly true.
