Bayuk89 Posted March 19, 2016 Report Posted March 19, 2016 Here is an email response i got days ago from sundown customer service. The SA18 needs a net volume of around 4-4.5cuft. per woofer.. They displace 0.26cuft. tuning should be around 32-35hz *Thank You* Bryan Chamberlain Sundown Audio Public Relations~Tech support Manager~International Accounts 828-459-1980 ext118
Eric Bascetta Posted March 19, 2016 Author Report Posted March 19, 2016 Thanks guys for all the help, looks like im just going to build a box below the window line with sub up /port up in the center of the box - 10 cuft net with 140 sqin of port. I'll throw some pictures up once i start building the box.
Keith77 Posted March 19, 2016 Report Posted March 19, 2016 From my understanding subs forward port up works best in trucks if you aren't walling it. Thats cool. Im way too old to be upset by shit like that. Your name is winston. Your own parents hated you even before you were born. My penis is bigger than your penis I'm far from loud and my roof/headliner flaps around like Adam's ass on a windy day. I think it depends more on the structure of the vehicle.
Eric Bascetta Posted March 24, 2016 Author Report Posted March 24, 2016 I just got these subs (SA-18's) delivered at the house....i have never in my life seen a $199 woofer shipped look even remotely close to these. Monsters for the price ))
Eric Bascetta Posted March 24, 2016 Author Report Posted March 24, 2016 ok here's the design i came up with.... subs forward/port up 10 cuft net with a 16.75" x 8.5" port 21" long tuned for 35 hz (I will be doubling up the face and I have 1 cuft for internal bracing which i haven't drawn) im new to sketch up so bear with my crappy drawing lol....any comments or changes I should make will be greatly appreciated.
Eric Bascetta Posted March 25, 2016 Author Report Posted March 25, 2016 I changed it up just a bit with an interchangeable port, i will add bracing around the port opening in the box
Airborne Posted April 1, 2016 Report Posted April 1, 2016 I am digging the idea. I am kicking around what to do with the back seat of an f350 super duty and as much as I want to wall it I am leaning toward something along the lines of your build. I'll be watching...
Eric Bascetta Posted April 1, 2016 Author Report Posted April 1, 2016 I'm waiting for my neighbor to get his damn truck back from the shop lol. I will 100% follow up with the build
Airborne Posted April 2, 2016 Report Posted April 2, 2016 From my understanding subs forward port up works best in trucks if you aren't walling it. Is this strictly for spl or would it sound good better with music this way?
Eric Bascetta Posted May 2, 2016 Author Report Posted May 2, 2016 My friend finally got his truck back from the shop, here's a few pictures. I had limited time on sat so it was done quick and not perfectly lol
