So what caught my attention with this sub is the price. I'm not really limited on space but I assume this is just as good as any woofer but a shallower mount. I have two questions about it though.

1. What is the suggested rms ratting for this sub? Is it 500rms like in the name? Or is that like max/peak rms?

2. Also, what would be a very general ported box size for this sub? I'm guessing around 2 cubes tuned to 32hz or something?

Thanks!

These are a very sturdy 500 watt rms driver. I would not hesitate to use a pair on an Sundown SAX-1200D amplifier or something similar in power output. They will use the same box sizes as the SA line.

here you go my good man! all the info you need to know and more!

the specs there can help with design for your box!

I am getting one for sure in 12". Does anyone think I have enough power for two with my RF power 501bd amp? I currently have it hooked up to a RF HE2 D4 sub wired for 8ohms and my sub gain is all the way down. I'm going for a ""SQL"" setup. If I only get one it will be a D4, and if I get two I will get D2 coils so I can run them at 2ohms. Any thoughts or suggestions? I also have a solid 14.4 V going to the amp via a 220A mechman alt. and a xs power d3400 battery with all HAT speakers in the front stage, 3 way active processed with an MS-8.

i will try to get one sd-2 12 also powered with autotek mm1-1500d

should it be good enough to power it

That is more than enough power.

You only need 500rms or less unless your planning on a upgrade.A d2 or a d4 on the voice coils?

The RMS rating has nothing to do at all with how much power you need.
