Thinking about building building a sub box to fit under the rear seat of my '05 ext cab. Should I build it so the woofer is firing up through the rear seat or firing down to the floor? How much air space should I allow between the woofer and the floor or seat bottom? Would an inch be enough to allow the speaker cone to move and let the thump out?

 

Thanks

An inch is cutting it close, but it really depends on the sub and how much excursion the cone will have.

 

Ever thought about pointing it towards the front of the cab? Size limiting of course.

Just finished building a small box to hold a single 10 inch Rockford Fosgate Punch. This sub is can be used in smallish sealed enclosures, rec volume is .65 cu/ft. After subtracting for the speaker displacement and the internal bracing, my enclosure endend up at a hair over .72 cu/ft internal volume. I built it a bit larger than recomended figuring I'll throw a buch of poly-fill inside and try it out. Can always glue a block of syrofoam inside to take up some volume if needed. Got some sanding and finishing to do tomorrow.

Is that plyboard?

 

3/4 MDF is my material of choice.

Yeah I know MDF is the material of choice for sub boxes. But I'm a cheap S.O.B. and had to find a use for some pf the scrap plywood I had laying around. Nothing invested but a couple hours on a rainy day so far. Sub has been ordered maybe I'll get around to trying it out next weekend.

Update

 

Well here it is sanded, primed and coated with Duplicolor brand sparay-on bed liner. Used some 1/8 inch foam material I had left over from a flooring project, to line the inside of the enclosure. Couple of #10-32 machine screws, washers and nuts worked pretty good for speaker terminals (yeah I was too cheap to buy the terminal cups)

Rockford Fosgate includes a nice stick-on gasket with the woofer. Had to ditch the magnet cover as the internal bracing was in the way. oops

Finished product.

The textured bedliner finish fits well with the Work truck interior, looks like it belongs there.

Still can't try it out, Waiting for Fed-Ex to deliver the amp wiring kit and Excelon KFC-X170's and X-460 co-axials. :) Did recieve the Kenwood head unit and Pioneer amp though.

      Towing In Loose Gravel

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?

      The use of absolutes like "always" to describe gear selection, and giving free advice at a boat ramp sounds like a recipe for disaster. It's a boat ramp, not a farm, for starters.   IMO gear selection should depend on the obstacle. If low range is working and this is a slower speed, controlled ordeal, I'd keep using that.

      I had a boat for many years, never had a problem even with a 2 wheel drive 93 Silvy for 20 years. Good tires, proper use of the gas pedal worked.
