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 buy a box. you can save all the time and aggravation. i had a downfire in my ext. cab and it sounded great.

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.

Yeah, the basement is bleeping mess haha and yeah I got a little carried away with the Gorilla glue.

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.

      Trading 7.3 (Godzilla) for G.M.C gas

      By KARNUT · Posted

      My nephews 7.3 got noisy right around 100K miles. While replacing the engine he drove his old 6.0 Chevy that had over 200K miles on it. It an old reliable backup. I haven’t been around the old shop lately. I’m curious to find out if there using the new GM heavy duty gas.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I don't know if you or anyone enjoys it or not but, why not share it. It's GM "truck" related and we're in the right place to discuss that 😉 I'm also working on some creative writing skills, I'm not quitting my day job to pursue that, either!   As I said, I've hit a wall because I'm not making any progress, and the progress is the fun part for me.   The idler pulley and EGR valve came in. Against better judgement, I went out there last night and put both of them in. I was able to get a nut on the back of the bolt on the side with the broken flange. There's enough flange still there that I can get that side of the EGR to snug down. It's not perfect, it's not "right", but this is the fix I have for now. If I decide to keep the rig, I talked to a guy locally who will sell me a complete intake for $100. If it's my truck, a broken flange like that would bug me too much. Yes, I'm crazy. But I embrace it.   Pulley on, EGR installed, started the truck. Great...still have a pulley squeaking like mad. That was the first disappointment. I thought I had pinpointed the problem. Before I replaced it, I sprayed the back of that pulley with PTFE and it would shut up for about 30 seconds. Is the squeak actually the belt? I'm frustrated.   SO then I decided why not disappoint myself twice, so I took it for a spin and sure enough, the CEL set for P0401 insufficient EGR flow again.   I had some extra time, so when I arrived home, I decided to ask AI about my EGR code. We had an interesting conversation.   I asked how to tell if my MAP sensor is bad and if that could be setting an EGR code since a bad MAP may not be sensing the requisite drop in manifold pressure when the EGR activates. I gave it the MAP value at idle and it told me to blip the throttle hard and watch the MAP reading. It said no, the values appear normal and it's reactive to pressure changes, and then instructed me to test voltage at the harness. I don't think it's the MAP sensor. Interesting, though, I gave it MAP reading values in inHg, and it thought I was using PSI, so I had to correct it. AI is a very dangerous tool if you aren't treating it like the machine that it is.   Then it walked me through testing the EGR and harness. It took me down an interesting path. It was referencing a gray wire and a white wire so I told it I can't tell the difference on my harness because it's dirty and old and both could be white or gray, I'm not sure. So it gave me a more accurate description of the ABCDE pins on the connector and started referencing pins instead of colors. Helpful.   The EGR harness has 12v power, and it also has 5v reference power from the PCM. What I'm unclear on is there's a ground wire and I thought AI had said that one of my tests revealed the ground in the harness was likely bad and it instructed me to wire a test ground. I got distracted and navigated away from the AI conversation, and when I went back and asked for clarification it said I must have misunderstood. (how rude- next time I'm saving the conversation!)   But I think it was onto something. I recall NOT getting 12v when I tested the power wire to the ground wire, but I did when I tested the power wire, grounding the voltmeter to the engine block. AI said no, the ground wire is actually for the PCM, that's how it commands the EGR on by grounding it and so the circuit should be open with the key on (i.e. EGR off). But I think there's also a static/overall ground that should always be grounded, and if that's bad, then the EGR isn't activating when the PCM commands it on, and thus setting the code.   There's a bunch of other tests it suggested, back-probing with the EGR plugged in and engine running. I need to get some time to focus, and not just tinkering after a long day.

      the 7.3 lifter issue is real, not few and far between.  my 6.6 gas does not use oil.  the 7.3 with 4.30 gears pulled hills better and felt better off the line. the 6.6 gets the job done though. mpg sucks

      Slate Electric Truck

      By Donstar · Posted

      I am a huge fan of the Slate.  (SUV for her, base pickup for me.)  Unfortunately, there are no plans to sell in Canada but maybe this will change.  I think if/when Ford offered a high range. EV Maverick, it would be my first choice.
