thanks to everyone for your ideas

There are a few companies that sell the shallow sub woofers and the shallow boxes, I measured some a while back at best buy i want to say. They will fit if you remove the seat. That is what I was thinking of going with.

Here's mine. I just wanted one small 10" sub cuz I'm at the age where I don't need to "bump".....just wanted quality sound. In the truck, my amp is mounted to the enclosure as well and you will have to use a shallow design sub. Even with the tank removed, there's not alot of space to work with and you will be limited to your choices of equipment.

beautiful now this is what im looking for...
what kinda amp is pushin that sub n how many watts???

and if u dont mind what thickness is that box???

[nicolas72gmc]

Hey Jim, when you get that box in there will you take some more pics so we can see it installed? I was curious on how you were going to mount it to the back of the cab. It is a very nice enclosure by the looks of it!!!!

[lclippard]

SactoJim, That is a nice box. Is your tank still behind the seat?

P.S. Looks like the truck isnt so bad either

[4tiresngas]

SactoJim,

That looks pretty sweet. I'd like to see it after it is installed. How will it mount in the truck?

[nicolas72gmc]

You could try Bazookas also. I don't know what diameter the enclosure is but it might fit at the bottom where it is the roomiest (is that even a word?) . Anyway, let us know what you come up with.

I have also been tossing around the idea with my truck.. Then i found 3 small leaks in my stock tank so its getting tossed out of the truck and going to be putting in the speakers when i get the extra money.. I dont really think you would need 2 12's in that small of a space.. Lol we have 2 12's in my Girls scion and it is more then what i would ever need... i think i am just going to go with one 10'' like sacto

if i was to go with one sub it would have to be a w7 but thats a little too spacy for me rite now i think id b better off with 2 12inch mtxs im younger and i love bass...

id like for ppl to hear me coming from blocks loud pipes n super beat lol

[SactoJim]

Here's some pics of it installed. Right now the thing fits nice and tight and nothing is holding it in and it's not going anywhere. I have to make a finishing piece that runs along the top (ribbed area) and use that to tie in the speaker box.

The amp in an old Soundstream Reference 405 amp...back when they made real quality products and I've had it for a long time as well as the door speakers.

The doors already had gigantic holes hacked from PO, so I fabbed up a piece of flat metal to mount the components into. I also built an aluminum shield that is installed in the door that keeps water away from speakers. I'm just about done with some lower door panels to cover the speakers.

....anyway works and sounds just fine to me.

[russj67]

I bought 2 10" Rockford Fosgates Shallow subs and then covered some plywood with some vinyl to hold everything in place. Mounted an amp in between. Haven't heard how it sounds yet because I just got the wiring done...well, almost done.

[mikajo39]

I had two 8"s under my seat powered by a way underpowered amp wasn't half bad. Doesn't take much to bump hard in these trucks because the cabs are so tiny. I put a cheapy JL 10" in my buddies 82 toytoa 4wd and it is INSANE! SO much bass for a little cab. If I had the bucks I'd spend it on one of JL's thin 12"s

[mikajo39]

Here was my cheap install two 8"s and two 6 coaxials crossed over at like 650 Hz. It cost me practically nil and wasn't bad but it wasn't great either but hey I got bored on a friday and said what they hay might as well.

[MudBug]

How much extra room do you get behing the seat when you take the tank out?

[russj67]

About 6" at the bottom and it gets down to around 4" around 3/4 of the way up. Not a whole lot of room, buts its something.

[Beatcoaster]

Fastom, I plan on doing something resembling your setup once I move my tank, I bet with those rear components it really helps out the soundstage. Having no rear fill sucks...nice work!

Here's mine. I really like 8's in this small cab because they don't rattle it apart, just produce nice full bass from the music. I have 2 Polk 8's along with Polk 5.25 components in the dash and Polk 6x9's in the doors, powered by a Kenwood head unit(5.25's crossed at 100hz) and MB Quart DSC480(6x9's full range and 8's crossed at 100hz). It was a damn tight fit under the seat but I can't imagine needing anymore bump or spl for my 34year old ears...until I move my gas tank and rebuild it with 2 more 8's and a bigger box where the current tank is!

Trying 2 box designs

Settled on this one, as my 250lb butt still never touched it during excursion even with the old seat springs

Wouldn't even know there was a badass setup in here, until your butt starts vibrating and your ears bleed...

[Andy4639]

OK here goes. This is fixing to get moved to the audio section since I'm posting mine. I know it will because every other one has too!
It's not a thumper but Brooks and Dunn sound great!



Got the tweaters almost at ear level used the clothes hanger mounting hole to screw them in with.





Built mini inclosure for drivers side three way.


Passenger side is in the orignal case.


Have 2 singles up in the dash above the radio. I have 2 amps. 100 watt and a 400 watt.

whats the dimensions on them sub boxes you have i think i have
sum in the garage... And did u fab them or buy them???

[Beatcoaster]

I fabbed them myself, and will have to measure them tonight, forgot what dimensions I was using

info on that would be great...

do you remember the width of the wood you used???

[Beatcoaster]

Custom_10:

The boxes are glued and screwed with 3/4" MDF, with a 3/4" recess ring getting the woofer below the top of the box. I bought some terminals from parts-express, installed those and caulked the interior of the boxes. then carpetted them with spray adhesive and box carpet. Then install acousta-stuf, a butyl gasket(3m windowsealer) on the speaker ring and finally install the speaker compressing the butyl rubber ring and screwed them in place. Height of the boxes is 5.5"x13"widex15"deep which is giving me about .30 for an internal volume, the speakers spec'd at .35 but they still sound nice.

Be aware that the woofer must be placed rearward of the seat's front springs(notice placement in the box) and that you check to see if your seat springs depress into the woofer cone(mine may be stronger than others - or weaker). This can be accomplished with a friends hand between the seat and woofer cone and you simulating bumps with your full weight on it(my wife was scared about me squishing her hand - but nothing happened! ) With this setup you must place the speaker boxes(not bolted) then install the seat. Slide teh boxes around a bit to position and then bolt down the seat. The seat cannot be bolted first as the boxes will not slide in due to the ridge in the floorpan. Because of this you cannot install the inner rear seat bolt(unless you have a magic contorting wrist and socket wrench so be sure to get longer and stronger seat bolts/bigger washers as you will only have 6 now. On a positive note, there is no way for thieves to access of remove the amp/speakers without unbolting the entire seat and removing it, and the boxes will not slide anywhere at all...


Feel free to ask anymore questions!

[ya it is a classic]

alright so this thread is super old but heres my set up. i dont have pictures but i had 2 6in speakers 1 in each door. racing seats with 13 1/2in between them i believe and i put a 10in jl audio sub in a sealed box that was 13in wide. a $250 pioneer head unit that i screwed down on top of the box with both the sub and speakers running off a 600 watt alpine mounted under the driver seat. phoenix gold equalizer. 4 gauge wire running from the battery on top of the frame and up through the floor. lets just say i pushed the 10in jl to the max and blew it so i put in a used kicker comp and was very disappointed so i bought 2 12in jl w3s? in a massive ported memphis audio box and just took out the passenger seat. then i put the subs and amp in my 99 grand prix gtp. same setup but the speakers arnt amped yet. even with only 600 watts, playing some gangsta music those subs bump!
