3 8's?

I upgraded my stock system to 2 12's when a good deal on the box, amp and subs (all memphis audio ) rolled around but the box doesn't fit under the seat at all. I went to my local audio shop and they said they could build a box for 3 8's but they wanted a fair amount for it. (1300)

What would y'all run on your trucks?
I like the 2 12's but would also like my rear seat back [emoji23]

I thought this would be a tire thread. Lol. FWIW a single 10" sounds amazing if you have the right amp.

LMI sells a seat lift... Thats what I used to get my box to fit under my back seat.

Most companies make shallow 12s
