The ssf is set at 50hz which is all the way up for some reason, where should I try and set it and the bass eq and the x over at?

Lol yeah thats not helping. Drop the ssf only enough that the woofer dont play too hard under tuning.

Since the box is tuned to 32.5 should I set around there to start with?

Sure. Some amps dont necessarily have an accurate SSF value printed near the dial so just make sure you've got it correct by testing.

Thanks man, I'm going to go do some adjustments and I will let y'all know. The sa8s sounded really good so I didn't think about making any changes for the 15.

If your ssf was all the way up with the sa-8's then that zv3 will KILL the lows compared to the 8's.

OK so I adjusted the ssf and it helped some but I didn't play the sub enough to get it really warmed up to see if it will loosen up and play the lows better. The mid bass is very loud though. I'm sure if I had this same set up in a SUV it would be killing lows lol.

You want "SSF" (infrasonic filter) about 1/2 octave below tuning.  if you KNOW you're tuned to around 32.5 then set filter to 25-28 as a starting point and see if subs bottom out etc.

OK so I got in some play time with the sub and did some adjusting on my amp and it sounds better but what I have came to realize is that I simply do not have enough power for this 15" sub. The sundown sae1200 worked really good pushing the 4 sa v1.5 subs and I expected it to push the zv3 15 enough to equal or surpass the loudness of the 8's but it just isn't enough power. I did change the tune down to 30hz and it now has the bottom end lows that I was looking for and I think it had something to do with it being in such a small area of my reg cab Dodge ram. Thanks for everyone's help and this is a great site for information and technical support, thanks again
