these are my 2 12's
i have like 10" of trunk space left

each speaker is an mtx with 400rms and 800 max

my amp is a 2 channel 1200watt amp..

 

Whish I had some bump. Nice install

 

I love the MTX subs.
I have a single 12" and it hits hard. it looks like the same model you have.

I'm planning on getting a second. They're nice, low price, quality, sound great, and plenty loud for our small interior!
