Bolt Terminals.

[Semper]

Okay, so I want to install some copper bolts as terminals for my box.

How many do I need for 2 subs & how exactly do I use them?

Idk why, but my brain just cannot process how exactly I wire them.

Each sub to each bolt terminal, assuming I only need 2. But then how do I wire them to 1 2 or .5 ohms from there?

Pics would be helpful.

What subs do you have 2ohmDVC or 4ohmDVC that decides your wiring options.

You put the two bolts in the box. You only need two unless you want to be able to switch coil config on the go but I'm guessing that over your head.

Than you wire the subs to the bolts on the inside just like you would to the speaker terminals on the amplifier. You will need crimp on ends that will tighten under the nut on the bolt and make a good connection. Than you run wire from your amp to the corresponding bolt.

I wil draw a rough diagram in pain lolz hold on.

This is for dual 4 ohm subs to 1ohm final impedance. If they are 2ohm wiring like this would make a .5ohm load and instead you should wire to 2ohm.

What subs do you have?

I'll be soldering the wires to the terminal, instead of crimping. So it'll be a decent connection.

I plan on using Copper Bolts.

I just want to know how many bolts I would need to be able to change between .5 & 2 ohms. I'll be running 2 ohm for the time being, I just want the option to change, without having to remove the subs from the box.

1 pair for each coil gives most options...

[Chris Hammer]

Yea thats alot of wire and bolts just so you dont have to remove subs.

You could have two sets of bolts. One set for .5 ohms and have it wired that way....and another set wired to 2ohms. Thand make sure you cap off or cover the bolts not being used....than you could only have 4 bolts but 2 different coil options.

You need 8 bolts.i would have each negative and positive on there own bolt for all wiring can be done outside of box.

Let me know how that finding copper bolts works out for ya cuz as far as I know they don't exist. Use alum or brass.
