My aunt decided to add some bass to her truck after hearing my 18. Goal was to add bass without sacrificing any space since she has a teenage kid and its her daily driver.

Going in -

2 RE RE-X 8"
Alpine mrp-M500
Kicker Wiring all around
LOC (Not wanting aftermarket HU)


Power wire ran

Box

1.2 cubes after displacement tuned to 35. Designed to fit snug under the rear bench seat.


Got the box done, ran all the wiring, installed the amp, got the LOC installed. Tried the subs for about 10 minutes and I'm pretty surprised. For how much they cost and what they are, they're pretty good compared to other drivers in the same price range and size.

More pics in the morning.

Box ended up sitting too high for the seat so I made 3/4" risers for the seat mounts. I'm carpeting the box tomorrow and then it will be put in. Then I'm going to put the seat back in on the risers.

More to come.

Looks nice!! My friend has 2 REX 8's like those in a 2009 Dodge Ram 1500 under the back seat. He has about 115 watts going to each of them and he loves them. How many watts do you have going to them?

They're wired to 4 ohms on the Alpine so about 150 a piece. I want to try upping them to 200 a piece and see how they do.

My friend also has his at 4 ohms. He would like to give them 200 at 2 ons but he can't because he has a mono block amp so there's no way to wire both at 2 ohms.

If I decide to change it, I'm gonna wire them down to 1 ohm. What amp does your friend have?

Ended up making a new port and adding polyfill. Whoever said polyfill didn't help much in ported boxes was an idiot.

3" x 20" for a lower tuning

Box build pics I forgot to add

use sheet polyfill in ported boxes so it can be stapled to the inside walls a lot of home speakers do this

I used normal polyfill with spray adhesive lightly so that the big 'chunks' of it stuck to itself. Sprayed the inside walls as well and so far nothing has budged.
