Porting a hole in your box wall...

carshateme · 27th September 2011, 09:41 PM

Okay I just got a brand new dual box and I plan on parallel wiring my sub woofers, but there is no hole in the middle wall for me to do it. If I cut out a hole, (about a deadbolt size drill bit) will that affect anything? The speaker wire being used is a 8 gauge...(old power wire for amp, upgraded)

Need an answer asap before I just go ahead and decide to do it. *The volume of the box is approx. .97 cubic feet. (if the volume changes a little bit, I'm fine w that, considering I wanted a 1 cubic foot box.

If it's a sealed box, it won't matter. If the enclosures are vented or passive radiator, keep the hole airtight. An easy way to pass a wire through a wall and keep it airtight is to drill holes just barely big enough to fit the wire through, then seal them with window & door caulk.

you dont have a smaller drill bit? lol

if its a wood box, just go get a cheap right size bit...no need for an expensive bit

Run two long screws through the middle wall a few inches apart and solder the wire on either side.

Brass screws then??

Funny you should mention that, the last time I did it, they were brass screws.

Heck you could punch some small common nails through if you didn't have screws on hand.

Err? What? lol. Nah, I have a deadbolt drill bit from way back...but I ended up using a drill bit about the size of my wire...and paralleled them...box is small as heck, but I'll have to see how well it performs before throwing my old ones away. Didn't have to solider any wiring. My Subs...have 4 wire terminals on each side... so I have room to shove 2 8 gauge wiring in one terminal while the other terminal is used to parallel the speaker.

Yes I love to use Paint so this is the diagram...a pretty crappy one...but here's how it's wired out.

Use a terminal cup and connect on both sides.

If you have access to a jig saw. The OP seems to have but one drill bit.
