i want to build a fiberglass box in the back of 86 z28 camaro. But not sure what type would be the best. Should i do a port or free air box. Any input would be greatly appreciated. THX

If this is your first fiberglass box I would go with a sealed enclosure that matches the volume of space your subs need. If you need any tips on how to do It I have a few posts showing some boxes I have built and I'm sure there are plenty of other users that have done the same. What equipment do you plan on running?

If you can get the volume on the box right for the port size then I'm sure it will sound just fine. I dont know how to figure out how large the port should be though. If you are going for pure bass and less sound quality I think a ported box will be louder. If you want to to be more crisp but not hit as hard I would go sealed. It all depends on what you want it to sound like I guess. Hope this helps.

If figuring out the box volume is your only concern, read the following. https://www.the12volt.com/installbay/forum_posts.asp?tid=115452&KW=i+am+an+idiot#560642

If you do build the box, make sure you angle the woofers toward the front of the vehicle. It will not sound good at all if you fire them straight up into the rear end of the liftgate. You can get around 6 Cu. Ft in that car using MDF. You have to go to the bottom of the well, take up the entire well, and most of the area behind the rear seat. Above info is only if your car is not equipped with the automatic trunk closer. I think they started putting that in the cars at 88.

Let's Go Brandon Brown. Congratulations on your first Xfinity Series Win. LGBFJB

what are your plans to figure out the volume of the box? I think the easiest would be the packing peanuts....? Well take photo's as you build your box and let us know how its going along. Thanks
