Impala-Chasing a 50 on the TL-Build log (Rockford Fosgate,Soundqubed,Alpine,Sundown)

[Impalalpine]

This is my seventh gen impala i'm building. I'm not all the way serious about the 150db thing, as it would take alot of fun out of it, making compromises. It would be sweet though.

Blew the type S 15's you see, many many pictures yet to be added.

Equipment:

Soundqubed-3500D.1

Rockford Fosgate Punch 500.4

Alpine type S 6.5 & 6x9

Knuconcepz 0 and 4 gauge, distribution blocks and krystal RCA's

Pioneer-DEH X8600BH

Sundown X 12's (yet to be ordered)

Im going to try to fit a huge kinetic or D3100 in the factory spot under the hood. and then another kinetic in the trunk.

how do you like that 120.4? Im slacking pretty ridiculous on mid's and high's. Have you taken the back off of it? i would love to see what its like

You going to do port subs forward in a sealed off trunk? A lot if petiole get loud in sedans like that.

[Impalalpine]

forward facing port into seatback. partial seal off from the trunk

forward facing port into seatback. partial seal off from the trunk

why not fold the seats down and do a full seal off.

I use my rear seats all the time. Will it function properly if I cant give it the open cabin to fire into? am I better off firing into the licence plate again?

I guessss I couuuuullddd... maybe give up the rear seats..

150 from the trunk of that car won't be easy. My boy David went through a lot and was still in the 48-49 range. Granted, he was tuned low. The link for motivation LOL:

Sealed trunks can still use their back seats. It's all in how you build the box and seal it off from the trunk. Look at sealed trunk build fir ideas

What do you guys think?

Some fiberglass, the recommended bracing, and a double layer baffle facing the seats?

6 cubes tuned to 31hz with 93in2 of port area.

Should look like this
