Audio Upgrades 2018 SuperCrew

Guys i just purchased 2018 SuperCrew Tundra. It doesn't look like there are alot of boxes for some reason that fit in the rear behind or under the seats. I think they missed the ball with under the rear seats being solid. What are my options. I had a fox acoustics box in my f150 under the rear seat. I have the base NON/jbl head and factory amp under the passenger seat.

I also saw a website for a company called *********. Seems like they have some good items but I would personally like to know the manf. of the amps. Any feedback is great!

I currently have a mono block skar 800.1d and no 4 channel, and 2 10" skar vdx subs

I just replaced the same system you have with a Kenwood HU and complete JL audio package from James at Tech12Volts. IMO, 2 10" subs are plenty for these trucks. James will send everything you need and his custom made sub box fits perfectly behind the seat of the CrewMax. He will be able to tell you how much mounting depth is available so you can determine if your current subs will fit in the box. I used the W0v3 subs.

I have this sub behind the rear seat. It fits and is a tight fit.
