Can you guys give me some opinion on my proposed starting points for crossing the following speakers in my new 2 way active build?

::speakers::
AF GB15 in sails
SI TM65 MKiii in factory locations (2016 Ford Taurus SHO)
SI RM-12 (sealed in trunk)

My DSP is a JL TWK-D8 feed via Toslink from a PAC AmpPro4

Based upon my research I'm planning to start by crossing at 80hz and 2khz with a -24db slope. I believe that slope is recommended for a few reasons such as being a bit safer and also avoiding some phasing issues at the crossover point...?

Does this seem to make sense for these drivers? I don't have exact dimensions for my sealed enclosure yet....don't think that will matter too much.

I'd say those are good starting points for sure.

Not sure how much level you can get out of the GB15 crossed at 2k as I have no personal experience with that driver.

I think you have a good starting point...similar to my set up and i think i have my tweeter at 2400. Lower does not sound better to me.

Did you by chance use a capacitor on your GB15 for protection? If so what size did you go with?

Thanks. I know this is a played out question most people are sick of hearing but you never know what details a new conversation will yield. At least that's my excuse for asking it ;-)

Thanks. I bought some 47uf after doing the math but was hoping for some confirmation.
Just make sure it was 47uf and not 4.7uf. I, and many others sometimes seem to not notice that decimal point lol
