Sounds like a lot of “woof” for a car. I have a 12” woofer for my TV/music surround system and it can rattle things off the shevles.

Are you aware that you need to calculate and build your box with the right air volume inside and there’s more calculations for the ports you are planing. If you build your box right you’ll get better sound and the speakers will work better and last longer. Also you really want to isolate that 12” speaker from the two ten inch speakers if you are set on running them together. The different size or even different model speakers can work against each other when they share a common enclosure. I’m giving you this info to help you with your project in hopes that you realize stereo installers don’t just throw things into cars. You might want to call the tech line of the manufacturer of your subs, They have guys to answer all you questions and they will even design your box for you not just the volume but the dimensions of the box and port. If it were me I’d either run the two tens or the one twelve. If you sold one or the other and put the money into upgrading another part of the system it will sound better. I was taught that 80% of the music is mids and highs. Have you ever listened to a system with large high end subs and factory highs run off the deck. Those systems sound really bad. Don’t forget the rest of the system. Just my 2 cents good luck with your project.
