This is my first box build ever, so why not dive in and do a slot port. I rabbited all the joints/corners for a nice air tight fit. I also eased all the port wall edges to hopefully eliminate the chance for port noise. Let me know what you guys think. Hopefully I can get it carpeted today. As soon as it's carpeted and installed I'll take more pics.

Specs:
2003 2dr Blazer
JL 12w7
JL 1000/1
2.5 cuft
30 hz
Port width 3.25
Port area 48.75
Port length 52.5
31x19x19
Titebond II

Looks very good. I would have used your router to round over the port walls....

I designed and almost identical box for my 12w7 go to in my Ext cab sonoma, but I only got it half way built and then I lost interest. I've got to give you props though that looks good and I bet it'll sound great!

Thanks for all the good words. I think my brother might be making a new box for his 10w7. If he does than I'll make sure he takes pics of it as well.

thats not a box, its art.

no-one rabbits joints like that,

flush cuts screws and glue only ever.

one of the best builds ive ever seen.

1st box maybe,

not your first time with carpentry tho right ?

Definitely not the first time with carpentry. We build custom cabinets and furniture among other things. This was the easiest thing I've done in a while.

I agree. Might be your first box but you've fondled wood before. :eek:

Excellent quality.

you can make some money selling boxes here. lots of people will pay $200+ for a good box.

I've always been hesitant to do the "multiple turns" in a port. Normally I'll just do the first one in the corner and go across the back of the box, in order to keep the airflow smooth. Has anyone noticed any difference between having just one 90* turn in a port vs. having 3-4 180* turns?

groundpound4200
11-18-2007, 10:09 PM
I heard that the turns cause resistance and will lower tuning for a given port length. I used the multiple 180 degree method on my last box and I like it. No port noise but of you stick your hand in the port the airflow isn't constant if you move your hand around if that makes sense.

ANYWAYS... very nice box!! You should do up a tutorial on how you assembled it.

Nice box man!

Wonderful job! Only suggestion I would make is to paint the port area black, you can probably still tape it off well enough and hit it with a few coats from a spray can, it would be the finishing touch imo. Otherwise, good stuff, I've not seen something that well put together in a long time, barring some work from fishercustoms.....


Edit: REALLY nice looking truck btw, I've always liked blazers! :)

Yea I plan on painting the port black. Trying to do stuff the week of Thanksgiving when you are having 20 people at your place makes it tough to get things done, and then there is the day job.

Very nice job!! Only took like 2 pics to tell this may be your first box but definitly not your first time working with wood. Oh and for that table saw :yumyum: That thing must make building something like these seem like a cake walk. I love the rabbited joints too, that thing must be rock solid. And the flush mount with the amp is really clean. Same with the blazer too not too over the top but just plain ****.

I also managed to fab up some brackets to run dual alternators in my 03 Blazer. Could be a first, but I'm not sure.

dual alts definitely isn't a first...and you don't even need 2 alts anyways with the power you're running. :confused:

Google blazer and dual alternators and let me know what you can come up with. You tell my headlights and volt meter that I don't need any more power. This is no different than running a 200 amp alternator except I did it at 1/5th of the cost.

i would venture to say you have another problem. either that or you think a tiny bit of voltage drop is too much.

i run a kicker 2500.1 (birthsheet close to 3kw) off a 220A alt and 1 battery underhood. if i can get away with 3kw off 220A of power, you should be able to get away with 1kw off about 90A of alternator power. i definitely agree you shouldnt need dual alts (not that it will hurt, im just saying).

id be interested to see what kind of voltage you drop to. got any info?

im not trying to be a **** im just saying, needing dual alts for 1000w of power is hinting at a different problem, especially considering this is a daily setup which will see music which pulls a LOT less current and is dynamic.

did you do the big three? checked all grounds? ran grounds to battery negative if no adequate grounds were found in the rear of the vehicle?

X2 on all that^^^ BUT, that's a different topic for a different thread......VERY NICE ENCLOSURE for a first time enclosure build!! Impressive I must say. When I saw the pics, I knew for a FACT that you were no stranger to wood working! I come from a family of carpenters/woodworkers so I know quality when I see it and that, my friend is good wood working!

The big three has been done for a while now with 2awg power and 4awg grounds. Before at idle the voltage would dip way down into the 11's (11.15) and while cruising it would go down as low as 12.2 and hang out there. This is at ~75% of it's potential volume level. I'm also running an Optima red top. I also have other items on the truck as well like an air compressor for my horns. Now at idle it might dip into the 12s but most of the time it is low 13s. I am in no way disappointed with the results of what $75 got me.

most definitely. one of the nicest builds i have seen. even with access to tools like the original poster, i am sure i could not replicate that type of work.

pmpmstrb: do those amps have regulated power supplies? that would make it much less efficient which could be the reason for such huge drops.

Yes they do. They have the same wattage regardless of impedance (1.5-4ohms) and voltage (11-14.5v). I have seen others say that they require a lot of power.
