    I am building custom enclosure for gm crew cab 1500 and 2500 and extended cab 99-to present . these are custom enclosures not prefab . all are built out of mdf and fiberglassed internally. you can veiw these enclosres on ebay . my seller id is christyt3838 and have 100 percent positive feedback. these are thrown together sub enclosures. the crew cab holds 4 12s wit no moving back seat. the extended cab hold 2 12s wit 7 inches of mounting depth. i also have a crew cab colorado that fist ubder the back seat takes up no foot space and can hold up to 2 l7 kicker 8 inch woofers. all these boxes have logos inlayed under the carpet or vinyl . so checjk them out . i have been in the car audio industry as an iasca competitor , judge , but most of all i have been a pro installer for the last 15 years.you can also reach at tech12volt@yahoo.com for more pics

    you say internally figreglassed......


    So do you lay up the matte with the resin or just paint on the polyester resin and call it fibreglass? BIG DIFFERENCE...........

    yes i am well aware of the difference 15 years as an installer 3 years with full sponsorship competing in iasca in 95 i did 11 shows and never got anything but 1rst place in pro 1-150 was point champion for zon 8 that year as well competing in iasca pro divisions for years when you had a true sq format with both seat judging .so i think i might know the difference . but to answer your question it all depends on what the customer wants to pay or the application . the colorado boxes (They only hold two eights and are very small as you do not have much room) are resined internally for strength as is all of my enclosure the avalanch enclosure you see is fiberglassed internally. and it still folds down like the factory piece does but it will cost about 500 dollars. my extended cab boxesare fiberglassed internally on the seams for strength . my crew cab boxes are either resined or fiberglassed depending on what subs are being used. But if you would like i could build you a box entirely out of fiberglass ,finish it and paintit. but most people do not want to pay the pricetag that come with that box .But that is a good question. the highest price box i have on ebay is 200 dollars and thats for a vinyled box so no i want be complete fiberglassing those enclosures.i love your tag line i prefer its all overpriced junk.

    Well well well mister big shot competer!!! LOL!!!!!!

    Good to know that there are some folks out there that can build a box (unlike so many jackasses that think they can)

    Sounds like you have good knowledge of the industry. I my self have been through it all, demo vehicles for Orion and Rockford and Alpine, Cars that have finished first in I dont remember how many classes. Its all passe'........years ago

    But i must say this in reply to your box building technique's.....


    Fibreglasse resin painted onto the wood does virtually nothing to the performance of the sub or the way it interacts with the vehicle. I have proved this a few times in experiments years past. And as far as strengthening the joints in the wood, again, i find that it does nothing as far as performance. as long as the cuts are accurate and the glue is quality, the box doesnt even need silicone to seal it!!!!!

    I am that particular in my enclosure construction. i measure in 1/128ths and my table saw enables me to be that accurate.

    i am NOT slamming you or how you build boxes! As a matter of fact, anything that you do to a box to help its rigidity can only help, but i have proven otherwise with the fibreglasse.........


    BTW, looks like you make some nic boxes! Post some more pics of your designs and installs, always nice to see some nice installs!!!

    i agree almost

    well like you i have been doing my own little testand i agree with mostly. and i have found that mdf (any thickness is slightly porous). it breathes just a little so resining the inside does have an effect not a huge one. and yes glue will hold a box pretty well but i disagree that it will seal it up. it will leak over time . todays subs would blow it apart i see them come apart with glue screwa and liquid nail . and hwere did you get that table saw ,nasa . but mostly we agree i can tell you are from the old scholl as well. bet you dont even wear a mecp patch on your sleeve:lol:and one more thing i am not a competer any more to much drama i know how good i am and dont need to prove anything anymore not being an ass but that is what a show is its showing how good you are or how much money you can spend and thanks for the cmpliment from you that means a lot . you seem to know the differece as well about a thrown together box and true sub enclosure

    If glue won't seal it then your cuts aint straight, try using a table saw.
    Also use a better glue, Elmers Carpenter or Weldwood Wood glues are awesome. And non of my boxes have ever come apart, or started leaking.

    Now I'm not a Pro installer, just an old installer but I have built alot of boxes

    By the wat,I love that Memphis box

    my cuts are straight i di not say my boxes come apart. trust me they never come apart. but i just dont trust glue alone . personal thing i guess. and thanks gl;ad you like it. it still folds down in the avalanche . it was a bitch to get lined correct

    Nice im really jealous. i have a delta industrial that can cut up to 48 inch spans . my dad is an engineer and built it . i also have a panel saw that i bought from a lowes that was going out of business but its a real pain to use . my next purchase is going to be a computerized router but it will be a while i have 4 kids that have to eat everyday.

    CNC router (now i am spanking the monkey!!!!!!!)

    we have one at the plant i work at, VERY nice peice of equipment, vaccuum table, dust collector, and WOW, the accuracy and repeatablity is excellent. Would be a GREAT way to go for box construction, If you have the money and space to set it up.

    Hey tech12, i was looking at your photos, not too shabby! I like the details with the raised lettering/emblems.


    But i have a question for you. looks like you deal in Memphis equipment quite a bit.

    In your HONEST opinion, how good is it compared to, say, OLD school orion? All things being equal. You know, durability, longevity, SQ, etc......

    A new local car audio shop opened up here in the area and carries the stuff, didnt sound too bad. Just never had any experience with it. Curious ya know......

    yes one of my oldest friends has one at his sign shop and i use to cut lexan somtimes ( i try not use lexan even on amp rack s)if the customer just has to have it. theres a mdf plant about 20 minutes from my house so i can buy .75 mdf 8 foot by 5 foot for about 6 dollars a sheet by the pallet.if i had one i would try to build quality pre fab enclosures . because cutting is what takes so much time it has to be exact measue twice cut you know. its a plan that has been on the back burner for years .

    ok to be honest all ther subs sound good and will get loud and generally do not blow unless they are really abused. the pr amps have given me some problems especially the the 4 channels.the mc amps are bulletproof especially the class d monos small compact and 1 ohm stable very stable even if current drops. they actually remind me of the old class a 6.0s by sounstream when you had to switch them from high current to high power manually. the blue ones . not the junk they put out after that.all in all its good stuff and very affordable. its hard to believe its the same company that made fultron (the fools that made a lifetime warranty tape deck) i guess they did not learn anything from cricket speakers lifetime warranty.its generally good stuff especially the mc stuff its better than good

    One of the other shops here is a Memphis dealer. I absolutely agree, the Memphis Class D is small and bullet proof. Excellent amps

    but the pr amps are going to be there down fall because your entry level amps better work or your customers will not upgrade to your mcs.now there pr mono blocks do fine as long as they are not pushing m3 or m1s .i think the mod woofers change resistance to much when moving for them.

    I really do like Memphis' higher line of class d amps...very sleek and powerfull...pack quite a punch for their size and weight

    I agree with you 100 percent, to me for the money i have not found a better amp than the mc s and the 5 channel with 1100 watt sub output is also bulletproof . one footprint, its the way to do it. xtant preached this years ago when they got there start and they were right.

    i could not agree more and what about the kick out of mc 250 for such asmall amp

    aznboi3644 Full Member

    what a kick indeed for 250 watts...Memphis needs to make a high power 2 channel MC amp....I like the mc 300 but not enough power for me
