Alpine type R 15' box help.


Recommended Posts

My buddy bought a box from his friend, and it was a piece of shit. I have half a sheet of MDF, and wanna build him a ported box. It's going in a late 90's Chevy 2500 ext cab. If possible, port up and sub up, and if someone could provide a visual for me, that would be great. I guess max dims would be 17" deep, 18" high, and 28 wide. I guess tuning preference would be around the 34 hz range ? Someone please help me out, thank you all.

Current setup in my 96 Hoe

Hu - Pioneer DEH-80prs.

Amps - (4) Crossfire C5 1700D's, MTX Thunder 5604(mids), PPI Art 300.2 (tweets)

Batts - 4 91ah rear batts, 50ah batt up front.

Subs - 2 Crossfire XSv2 18's

Alt - Singer 330A

Front stage - Random JL & Eclipse mids, Eclipse tweets
