jhagan how does your subwoofer sound? Any rattles when you turn it up?

thanks

jhagan

Sounds great..No rattels... I had one from the metal buckel on the tie down but I used some duct tape as a buffer between that and the box and it took care of it.. I also used some pillow stuffing( looks liuke cotton) and placed around the box to dampen the sound... I'll take more pic to show the material.. Please note this is my first box.. but it sounds better than the bazoka I had in my 240sx.. That for sure.. The bass is really tight.

cool, great job on the box. Did you have any problems with the two brackets (the two on top for the glove box)

jhagan

Thanks

Na.. I had no problems... the box fits with plenty of room. It slides right in on an angle.. I could have gone a 1/2 inch wider but thats it. Anymore and I wouldn't had room to work the box in.

Once situated. I just strapped it up and I'm good to go...

jhagan

Thanks for the idea..

for what its worth, i got my 8" self-powered kenwood tube in the compartment, with only some minor bending of the sheet metal... put a pillow behind it to take up the dead space. should be all finished tomorrow, will se how it sounds....

jhagan - Nice job on the box. I am in final process now for custom one myself. I look at your measurements and it seems that you have an Internal vol of 0.5cf ? isn't it too small? My sub requires a 0.75cf and I wonder what should my measurement box should be... any suggestions?...

Your Ext Vol is? 18X12.5X6.5 = 0.84cf
Your Int Vol is? 16.5X11X5 = 0.52cf ???

jhagan

You are right.. I screwed up.. and didnt take into consideration the thickness of the wood..I think a half inch in width will get you closer to where you want to be.. but I wouldn't go any bigger than that becasue there isn't much room to play with the box to get it stapped in..

I'm not juicing the sub with a lot of wattage so.. with .5cf It still sounds good.. Also my specs said fill the box half way with cotton( form) but I did a little less than that to compensate.. After I broke the sub in.. it sounds great..

Also after I built the box.. I dyanmatted the interior to get better response.. this help a hell of a lot.. It made think sound much smoother.

For the record.. my sub required the same cf as yours...still sounds good..

jhagan

I just took a look at my box.. I think you can do .. an inch an inch more in width.. there is nough room.. but getting the strap around the box will be a *****.. I think that will get you closer to the cf you wanted... check the measurements

Taya

Thanks, no doubt the power you use will help the small size and get you tight bass, great that you like it... I have a 150W amp that small... I do not seek for more... the 2 boxes I see you guys build here varies but are all 18X6.5X(12.5 or 14). My 2 options are now
1. 18X6.5X12 with 1/2 dense wood and have 0.8cf box (Internal vol)
2. 18X6.5X14 with 3/4 MDF and have 0.6 cf box (Internal vol)

My sub recommend 0.75cf with a range of 0.4-1.7

ANy thoughts?

jhagan

14 will fit.. but no room to bring the stap around.. I'm not sure how he secured the box.. plus I didnt push the metal brackets back like you so it should work.. BTW.. how did you do that???

Taya

Bending the brackets was a little tricky but the end results is that you need to find the right position while using a hummer and it will bent easy... Work from the passenger side and almost look up side down if you know what I mean, it took 2 min to take care of that once we found a good position to do that... Do not try to take the brakcets off they are welded pretty strong there, easy enough to bent.. hope that helps... do you think I can fit a 7" height since it is bent?

jhagan

With the brackets bent you might be able to go a half in deeper.. but you need to check the width becasue the wheel well might give you some trouble.. The right hand side isn't flat.. the wheel well protrudes a little.. I'm doing this from memory so check before you start.. I'm prettry sure you can go another hal inch deeper though...maybe more.. I wouldn't " f " with height... thats the one measurement I got right...

just go on ebay and buy you a sub box that doesn't cover your spare tire and golf bag area...lol

This one looks nice and you could even color in the Z logo.

Be careful now. You might have to register your car if you color in the Z logo.

Why did I just KNOW that that thread was going to signal the second coming of Dugan?

Zenxia06

lol... I have a different sub box than that one, but got mine from the same place. They are a good quality box, and look clean installed in the car.
