m.bohn007 Posted January 19, 2011 Report Share Posted January 19, 2011 Looking to do a new sound setup in my 05 crew cab. I currently have a sealed, dual 10" box that goes behind my back seat. Im thinking about getting a downfire style box to go under the backseat. Ive never heard how they sound for myself, any thoughts? Im looking at putting 2 Kicker Solo-Baric 8" L7's in it if I do get it. Quote Link to comment Share on other sites More sharing options...
paulguy Posted January 20, 2011 Report Share Posted January 20, 2011 There's not alot of room under a crew cab seat, i only put shallow subs in there. Way more room behind the seat and you can make it sound better imo. Quote Link to comment Share on other sites More sharing options...
mcmahan Posted January 20, 2011 Report Share Posted January 20, 2011 (edited) I have a 8" solobarac L7 in my ss its a rear firing sub and I will say this and you will call me a liar but in a ext cab truck it hits harder than a friends ss who has 2 12" subs under his rear seat. Its all about air space and cab space. here are some pics of my set up. The entire system was done by a member here uncald4 (Travis) he has sold and done a few set ups for others here he knows his stuff. I told him I wanted 12"s he said he was gonna do a single 8. I told him he was dumb but I trust him and boy was he right. I have never heard a 8 sound like this. I have 15 years as a installer and my dad had his own shop and has over 40 years of experience and he was impressed. I think you will like it. AVH-P4200DVD head unit Alpine 800 watt mono block amp Kicker Solobarac 8" L7 sub custom ported box by Gig Harbor Auto Works excuse my dirty carpet they are clean no hope this helps we were gonna do 2 8"s but the air space need there would be no room for 2 in boxes with the right air space. Over all I am very happy with my set up its clear hits hard and all the sound stays in the cab I have very little vibration too only thing I really ever hear is the roof vibrating every now and then.

paulguy Posted January 20, 2011 Report Share Posted January 20, 2011 Nice setup. The op has a crew cab though, half as much room under the seat. Quote Link to comment Share on other sites More sharing options...
m.bohn007 Posted January 20, 2011 Author Report Share Posted January 20, 2011 I did some research: The box im looking at getting has .5 cub ft of airspace per side. The recommended airspace for the subs is .33-.75. Sitting right in the middle. Quote Link to comment Share on other sites More sharing options...

I had a sealed box and it hit hard but I wanted more so I went with a ported box and it made a big diffrence. My opinion in my truck a ported box sounded the best but having a crew cab you have a little more space and I think you will be fine. Make sure you post pics when ya get it all done. I would love to see it. Quote Link to comment Share on other sites More sharing options...
m.bohn007 Posted January 21, 2011 Author Report Share Posted January 21, 2011 The box and subs seem to be a pretty good match. Im deployed to Afghanistan right now, so it will be a while before I get home to put all my new toys in the truck. My dads shop is filling up with parts right now.

I need to put dynamat on the roof cuz when it hits hard I can hear the roof shake. Quote Link to comment Share on other sites More sharing options...

m.bohn007 Posted January 23, 2011 Author Report Share Posted January 23, 2011 Did you reup for Korea? If you didnt - you have my condolences. Ive heard nothing but horror stories about it there. Haha. I'll be heading for FT Stewart when we redeploy. I had two Alpine Type E 12's, in a ported box, in my wifes Mazda 6. That was pretty ridiculous. I had two JL W7 13.5's in a ported box as well that I use to just set on my backseat when I wanted to jam/piss people off around town. They got stolen though. hahahah.

6.0vortech Posted March 12, 2011 Report Share Posted March 12, 2011 I had two 12" diamond audio subs in a cheap downfire box and scrapped them for a Sub thump downfire box with two 10" RF Punch XLC's and and hits wayy better now! Quote Link to comment Share on other sites More sharing options...
m.bohn007 Posted March 12, 2011 Author Report Share Posted March 12, 2011 The box that I got is also a Subthump box. Im really looking forward to putting it all in. Only 28 more days till im out of here and get to start playing with all the new toys! Quote Link to comment Share on other sites More sharing options...
Fors Posted March 12, 2011 Report Share Posted March 12, 2011 (edited) I made my own box for under my seat, IF I wanted a sealed box it would of been fine for my 2 Fi ssd 12's but I ported it and it doesnt even come close to my s10's Fi BL 15" so Im going to take one 12 out when I get around to it, should sound a whole lot louder. Nothing like having a bunch of spare audio parts in a closet though. So you should be fine with 8's.

stg313 Posted March 12, 2011 Report Share Posted March 12, 2011 I had 2 12" Pioneer Premiers in a sealed downfiring box pushed by a 1200w class D mono amp. Sounded pretty good but not good enough. I really like a LOT of bass. Definitely go with a downfiring box though, it makes a HUGE difference compared to up for forward firing.
