Nice car. I love the sound !

I don't know how loud are those 10s, but they should blend with your front stage ! It doesn't look like a monster sub setup (I may be wrong though). The Alpine type X are nice speakers, from what I remember. What don't you like about them ? Sometimes a new location can do wonders ! From the door to the A pillars or to the dash, you can have great improvements. What are your mids in ? a fiberglass box ? If so, it will be difficult to make them sound good ! Can't you use your doors only ? I'm not an installer, just thinking. You have good speakers, a good 4 ch amp : it's an install problem. You're in good hands with M5. Good luck.

Lots of good advice here ! Don't use rear speakers, they're useless, they won't be audible! Spend a little more on the front stage (better speakers, some deadening on the doors,...etc). You will never egret it. .

Show us some pics please ! We love pics !!!

How is set your LPF ? It seems low, but your picture is difficult to read !

How much volume do you have for your subs ? It looks like you still have (little) room left in the trunk ! Nice choice !

Your second post ?!!! Wow ! IMO you should not run 14v batteries on a 12v electrical system.

You have room to be loud ! Is that only for the box, or for batts and amps too ?

I have just got a 64 Go yellow iPhone XR ! I know you're not iPhone lovers, but I am !

I love this forum. even if they have nice (SSA) products, they only want you to improve your car sound system ! They won't push you towards theirs products. Buuuut I can tell you their speakers sound very good. I've tried several SSA subs and loved them, and the Evil tweeters are still in my car : they're amazing. Check the available room you have for the sub box, and work from there.

The prs 80 is nice...and looks good too ! If you already have that Alpine h u, maybe you can find a good little DSP to have full control like you want. I don't think you can find the Alpine processor H800 (or something) for cheap. It would have been a really good solution. I was in the same boat, I wanted to go active but mu head unit could not do it : I bought a mini dsp , following M5 advice (always !).

No love for iPhones here ? You don't have to get the latest one. An iPhone 6s+ or 7+ should be cheap enough to compete with those Pixels or Huawei phones. I'm thinking about getting a red XR.

Welcome to SSA !
