    I'll get a pic with my username right away. Just gotta move some things to get at them.

    I'm looking for 600 +shipping. price is negociable. I am located in Alberta, Canada.

  2. Suicide doors sells bar gussets, you can check them out on there site, if you have a plasma cutter you can fab your own out of 1/4" or larger plate and put the bags on your current bars. It still may be easier to replace the lowers with the right bars, especially if you have round tube right now.

    Its a heim kit.. I haven't recieved the kit yet. I'm thinking I may just slap some behind axle brackets... waiting to do my taxes first.

  3. Well guys I still got my reg cab 94 sonoma.

    I am getting a FBI heim 4 link from a buddy. I will also be getting a Sanden EDC with it, with any luck.

    I may or may not convert it to poly bushings. I will be buying a raised gas tank crossmember from AVS or Suicide Doors or FBI, and welding tabs onto it for my upper link bars.

    However I'm not sure what I should do for bag placement...

    I will be doing a notch. I can't do bag on bar because the bars are sorta skinny, there not meant for that.

    I will be putting a Blazer gas tank in the back behind the axle, so I'm not sure if two rearward liftbars would work without coliding with the gas tank (turn it into a 6 link)

    I can do bag on axle, behind the axle.. ?

    I was told to run sleeves behind the axle but I'm not sure if I want to. Seems like there easy to mess up, I want something simple and bulletproof for my first setup.

  4. Hahaha I see your in Edmonton.

    I'm in Ft McMurray.. we had an issue with the by law showing up, we were all sitting in the driveway with our snowmobiles, none were running, we just had parked them all in the driveway and sat to get ready.

    2 suvs showed up, and about 8 by law officers. 1 checked our plates, the other bunch argued which snowmobile was better.

    Seems like your neighbors are bitches. I have neighbors like that too. Theres a guy who rides his quad around every winter with a plow, and plows the sidewalk. Somebody reported him. He's doing it without getting paid burning his own gas, so people can walk in the winter, and somebody reports him, wtf?

    I don't really mind noise in the daytime, but if your in a residential neighborhood with a loud setup blasting at midnight, ehh.

    sorry if that was OT.

    Nice to see some people remotely close to me.

  5. Well heres the deal.

    I am constantly working on my truck. It now needs a paintjob after I finish some bodywork.

    I could fit my SPL-12s behind my seats, but I will loose foot room. It would be best if I cut the cab and the bed, and do a blowthrough. I am having a hard time finding the accordian gasket. My city doesn't have an RV center or camper shell dealer.

    I have posted my SPL-12s for sale on caraudio.com/forum. I have gotten one offer.

    Why I wanted to sell them, is because originally I could afford the amp I was purchasing, but with the drop of the canadian dollar and stuff.. however now I should be able to swing it.

    I am considering selling the 12s, and buying a couple (3-4) Digital Designs 1508s, and doing a box behind the seat. I'm sure the 1508s will get loud, but I'm wondering if it will be loud enough.

    I'm not sure what I'm going to do.

    Looking for some opinions.

    I have a 1994 GMC Sonoma regular cab.

  6. yeah bro all good! im just saying because i dont want you to end up being one of those people constantly "in progress" changing and never finishes.

    i've given you designs, as well as a few members here now your talking to gmonk which is cool as long as you pick a direction and run with it.

    u know how much metal i had to cut out o my car to fit the box? :o if it sounded like shit i would be fcuked sometimes you just gotta build

    -Drew

    Yeah I'm thinking of just doing the cutout then designing a box around that. I know the max the cutout can be is 42" cause of the filler neck bump.

  7. That's a nice informative long post. AND what I told you last night gearstix!! Don't cheat yourself or your woofers by doing it 1/2 ass. There are many skilled Nov builders on here that can design you something fierce. Get some designs, get some quotes, but wood, build, and get loud!! Keep in mind you might gave to do the blow thru after building a large shallow wall or small wedge if your not happy. Do you have an amp yet??

    Working on it. Looks like its gunna be a Massive 3000.

  8. Here's a little story for you to consider. I used to have a Chevy S10, regular cab. I tried a wedge box behind the seats, for two 12"s. It sucked. I built a bigger, thicker wedge (lost leg room) and that sucked too. Started going with only 1 of the 12"s.... which almost worked.... but started blowing the single subs.

    Finally I got tired of not enough leg room..... or speaker box cubes.

    I decided to hack out a 10" by 40" rectangle from the back of the cab, lined up with the same size cutout at the front of the bed. I did a custom boot that came out bombastic. Never leaked a drop in 8 years of use.

    Called RF back and said, "Okay..... Now tell me the airspace these subs > will do best in < instead of, what's the smallest they will work in.

    I then built a nice, big, cubicle shaped box, butted it up against the front of the bed....

    Hooked it all up.....

    And all these years later, I still remember that the first time I cranked it up (playing Dire Straights, Money for Nothing :-) I was completely floored !

    That setup worked so well, that even though I "tried" to top it, a couple of times, a few years later, I never could, and always ended up going right back to it, as it was.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    What I learned ? Little, behind the seat wedges SUCK ! If I had a reg cab, and had to have more cubes, I'd have to do another bed cutout.

    Fortunately, I now have a Supercab, because it would be tough to start hacking on a brand new truck.....

    Hack it ! And give yourself all the cubes you need ! (oh, you woud have to have a bedcover though..... I almost forgot that, as I always have)

    Peace,

    Fish

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Doh ! I just went bacxk and read your post again......

    I still contend that losing even 1" of leg room sucks, but maybe your like 5' tall. I'm 6'1" and love legroom.

    But I'm still tripping that you can squeeze 6 freaking cubes behind the seats of a reg cab ! What truck / year do you have ?

    I have to honest, the box I built for the blow through wasn't even 6 cubes......

    Hmmmmm,

    Fish

    I have a 94 GMC Sonoma.

    I just don't have anywhere locally to buy that gasket. I was kinda confused on how to make the box fit the cutout, but I guess I can just go and do the cutout (I think 42" wide is the max I can go as it has a bump in the bed on one side for the filler neck., not sure about height.

    I am the same height as you.

    I have a fiberglass camper shell to go over the bed

    I just don't know what'll happen if I go to paint the truck w/ the gasket in place. I guess it won't matter too much cause if you remove the gasket and fill the hole, when you weld the panel in, it'll burn the paint..

    I would have alot more box options if I did a blowthrough like you.

    Would have somewhere to mount an amp, especially if I bought a Massive P3000.1, which is over 3ft long.

    Its just I've never done a blowthrough and I'm kinda worried I'm gunna foul it up.

  9. I'm trying to figure out how to make a box, to fit behind the seats of my reg cab truck. I will end up loosing 2-4in of footroom, shouldn't be an issue.

    spl12sincabbox.jpg

    That is 42in wide, 25in tall, and 10in deep... gives me 6 cubes. I forgot to account for sub displacement and port displacement. I can make the box higher, but not wider or deeper.

    I'm not sure how to figure out how many PVC ports (using pvc to keep the cost down) I'll need to get the proper tuning.

    Mach 5's site says 3cu.ft per sub, and a tuning of 36hz. Would like to have the subs on the passenger side and port up on the drivers...

    I entered the drivers parameters in WinISD, and tried to fiddle with the box and I must have made a mistake somewhere.

    Subs are Mach 5 SPL-12s (2)
