Comments on: How to Build a Subwoofer Box for Your Car

on 6/10/2009 How can a subwoofer react faster?Is it related to the diameter of the woofer or the liter that woofer has?What types of woofers do you suggest for metal music fast as hell?

on 1/26/2009 a ported box is better than a sealed one if you are looking for more of the sound of the bass rather than the feel of it .. @ dazm

the subs are held in by anything from 8 to 15 screws dependant on sub make theyre more than adequate to hold it in no matter how much bass you pump through just use good wood screws @ miss v12 vanquish

you just draw a chalk circle where you want the port and drill holes around the inner of the line being careful not to go outside of it or too close then cut the hole using a jigsaw joining the dots file or sand and fit in the port @ straightthuggin

on 12/31/2008 I HAVE 2 10S(Q POWER)BUT I NEED TO NO IF A PORTED BOX IS BETR THEN A SEALED ONE......

on 5/29/2008 Any good suggestions for types of spray glue and carpet?

Also do I have to silicone the top of the box (where the speaker cutout is) like I did the sides?

And I'm slightly concerned on what's going to hold my subwoofer into place. I've got a 12 inch JackHammer (TM) subwoofer and I don't want it damaged if it falls out because of how hard it bumps.

on 12/26/2007 What are the best car subwoofers out there. I have a 12 inch car subwoofer and i'm trying to get the best subwoofer box that will best fit my sub. I have found this one ( http://sonicelectronix.com/item_2_Single+12-+Angled+Truck+or+Hatchback+Box+-12ANTCM-.html ). what do you recommend.

on 9/3/2007 if you already have a sealed box and want to add ported holes in it how would you go about doing that????

on 5/2/2007 I have built several boxes for myself all successful. But I had the room now I dont have the room so I have to squeeze 12's somewhere, and I dont have room for thick wood ether. I had an idea of useing 1/4 in ply wood and then covering it with 3-4 coats of fiberglass cloth witch is stronger than mat. Plus sony has came out with some new subwoofers that are 3-4 in. in depth. My hope is to put them under the back seats but they may not end up there.

on 8/22/2006 Here's a tip from a custom installer at a Place Called Custom Sounds:
What we do is to seal the inside of the box by using fiberglass resin instead of silicon, it bonds with the wood and pretty much welds the wood together, it will be airtight and hold forever.

on 8/8/2006 To easily seal all sides of the box, install the panel opposite your speaker hole last. Seal the enclosure before you put the panel on, install the last panel then reach through the hole and seal.

on 8/8/2006 Silicon gives off a gas that will destroy the speakers. Check your warranty cards. Use of silicon will usually void your warranty. Liquid Nails (or some similar product) is a better choice.

on 8/8/2006 I have come to find out using caulk works really well. It's cheap and affordable. I tried this on one of my boxes and heard a good sound. I built it for my cousin, and now that she has showed it off I have had 50 people ask me to build them a box in the past week.

on 8/2/2006 If you choose to port your box, use 3" PVC for custom installation. This was with my 2 12" subs and I used 3 ports.
It made the sound much deeper and I thought the sound was better and harder. Use the Internet to research the port for your box.

on 6/30/2006 Use Dynamat in the inside of the sub woofer box, it will give you better output. I put some in my box with my 4 15" subs and there's no backwave anymore, just deep bass.

on 6/30/2006 Use oak or birch plywood if you want the best bass. 1-2 inch thick, the wood won't give, ever. And unlike MDF, it wont fall apart if it gets wet. I run my comp 18s with no issue at 12,000 watts. Liquid nail, Gorilla glue etc. is all fine. Except silicon, it'll rattle loose before it keeps a seal (maybe not so with lower power subs). Also, put Dynomat (roofing tar paper) inside of the box. You get 3-4 spl out of an average 12.
