Wall building advice

Im going to make an attempt to build my first wall. Its in an extended cab full size and any and all advice about wall building would be appreciated. im still gathering supplies and equipment but im going to start here in the next few weeks... thanks in advance

how many subs and what subs u gana run

4 Rexxx 12's .. got a couple choices for amps would really like to get 2 stetsom or maybe a couple rd d9's.. not sure but 4 12" rexxx's for sure

theres alot of guys that are keeping the box and subs below the window line and are have alot of good numbers but ya stack the woofers and port drivers side

ya ... I figure it will be worth it to build the wall... my number should be alot higher then having one at window line which is what i have now.... you were at stringtown in the blue blazer right???

alright.. i have not heard drivers side... most of the boxes i have seen have been ported in the middle or accross the top... i figure i can run like 3 6" precision ports and it should be enough... im just worried about keeping the wall braced with 360 lbs of subs

yep that was me, what i did to get all the curves right for the face plat was took card board and cut and shaved untill it fit right then trasfered it to the wood,also made strips and taped them together. if u double the front or tripple the front it will suport those subs

basickly it all depends on what u plan on running as far as orginazations u want it to load on the pasengers side kick so if u port it on the drivers side and subs on pasengers side it will load in the kick pasegerside

thats kinda what i had planned using cardboard and i was going to double face and use MDF for the front and a harder wood for the second layer and bolt the subs... I was at stringtown in the sierra witht he 26's.. I started to build a show truck but got started doing this after i spent all my money in my truck... haha.. im struggling now but im learning alot every build so this should be a good experience

Probably just usac.. Meca only goes to about 4 places over and over and over... usac has alot of stuff around dallas and alot of tx trips that will be 3-5 hour drives

here play with this programe might help ya out, ok ya i think i remeber who you are ya there is alot of stuff to learn and can cost alot but good to here that ur hooked on audio. from what i heard theres gana be like 9 shows here in ok for usci

theres suposta be like 9 meca shows before there big show here ok all worth money

alright... ill try that site out... looks like it will save me alot of time

I did not see any of the meca... I think it is screwed up how they have it anyway as far as the money... you are better off building a wall and getting 3rd in modex then running under the glass and getting 1st in modified but 4th overall and out of the money... thats what got me at stringtown...i only hit 146.5 because i kept my boxes low

i went to the meca site... i gues sthey just have the big shows listed... hwere did you see there was going to be 9 shows??? i like how meca does peak hold because i have not got the money for enough batteries right now but some of their rules are pretty sketchy compared to how SB in usac is kinda wide open

ya it will help ya, u was the other guy that was tuned really low like 30 hz rang right, i tuned my box at 40 hz and burbed at 48 all year. mark eldrige said that he talked to a few people and thats how i know but ya thay didnt post them yet

Build what ur budget allows and ull do well but I'll tell ya what makes sense on paper doesn't always make sense in numbers the more u build and change sometimes the worse it gets n sometimes better it's just part of the guessing game if it was simple everyone would be doing 180z

Im not tuned that low... im at 42 hz... i got alot of cab tho and i think its hurting me and i havent dynamatted anythign yet... but i got my system set up to play not compete... i bump it everyday just to listen to... could set it up to burp and hit a little better

ya the batt power will help u out alot i still have my stock alt but 5 batts and i stay at 12.7 running a street beat ya i know what u mean by getting beat hell that guy that took first over all he did a 64 at finals in the kick, to get a high score at meca is hard, ya thats the truth but i have learned alot this year from guys here and other places as well, ok sorry rong guy but u could still listen to it every day and have a hell of a set up

Ya... im going to tune a little higher next time... at least mid to upper 40's... i still got my stock alternator but all ig ot now is 1 kinetik hc2000... i want to run at least 2 2400's but im going back to college and i dont got 900 just to spend on batts. But meca you dont need them as much as usac so hopefully i can place at some shows and be able to pick em up

i drop from 14.7 down to about 11 where i bottom out in about 10 secs... i need ALOT more storage

look here for batts much cheper also u can run the c&d ups batts thay work good ussaly u can get them for like 170.00is

ya my buddy has got a huge c&d... i will xheck it out... still tryin to get rid of alot of the audio i got layin around so i can put this thinng into motion

what u got might be interested, ya those batts are the same size as the kenitic 3800 thay are big but thay are good they say there not as good as those but heck i have had very good luck with them

i got 2 ma hk series 15's 2000 rms 2 ohm coils (250 each)
2 ma hk series amps 1800 rms (275 each)
2 500.2 kicker amps (150 each)
1 ma hk 598 800 watt i bought for my components (160)
1 12" l5 in ported box... (175)
the l5 and box and 800 w amp havent been taken out of the boxes yet and all the other have 8 hours max on them... not really competition stuff but good for a system if you know anyone looking for some bump.. everything is MINT

you wont be happy with the xxxs for spl. they sound great but suck ass for spl. get the sx or the mt if your shooting for spl and daily. and ive got nsb 170s(equal to 2-3 kinetic 2400) for 250ea plus shipping.

I agree with Charles,I have had sr's sx's and I had a friend who had xxx's and I did a couple of db's higher with sx's. Trade someone and downgrade and get cash with the trade. Although they do sound nice mt's will hit higher numbers.

ya.. i could not find the specs on the Mt's but i guess they dont have them. They sound like they can really get downa nd are not as high... thanks for teh advice

What would be a good amp to run 3 15's... fromw hat i have read they can take 3k to 4k wrms no problem... thats alot of poweer

i wouldnt do a wall with just 4 12s.. with that low of cone area id keep it under the window line to see better scores... now.. 4 15s on the other hand..
