Subwoofer box terminals and speaker wire gauge

[Golitan11]

I just ordered my Sundown SA-12 subwoofer with an Hifonics BRX1100.1D amplifer and KnuKonceptz amplifier installation kit (Kolossus 4 gauge). Here are my questions:

1. Since most amplifier installation kits do come with 12 gauge speaker wire, is it plenty for my setup (800-900W RMS @ 1 ohm, maximum 5 feet)? Will I need 10 gauge?

2. I also need a connection (terminal) for my box but I have read that terminal cups are ****. The problem is I will be moving the subwoofer in and out of the vehicle very often (I need my trunk). So screws or passing the wires straight through would be problematic. What do you guys recommend?

Thanks.

Inline shielded quick disconnects. Pay att to wire the male and female opposite on positive and neg so its dummy proof if u happen to be in a hurry one day. If u were to do stud terminals on the box u will have a hot positive just floating in ur trunk as long as the amp is on, not suggested for a removable enclosure.

A guy told me to use bolts with wing nuts. What kind of screw should I use and is 12 gauge enough? Thanks.

Ok I just bought two gold plated terminals with a wing nut on top. Here are my questions:

1. Should I use brass instead of gold plating or this the best? Why?

2. Should I change the wing nut for a normal nut or a wing nut should hold enough? Why?

3. How do I attach the old wires to the new battery terminals (yes I wanna keep them)?

Thanks.

Shop speakon-hpc-speaker-connectors from Neutrik (128 | 686,826,1510)

I would use 10 gauge.

Have heard of even wrenched wing nuts to loosen I would use some type of locking bolts inside the box but that's just me

Ok I got brass screws, nuts and whashers for my enclosure terminals.

1. I have two types of screws but I don't know which one I should use. I have 2" and 1.5" ones (with the same diameter) but the 2" seems to be a lot darker than the 1.5" (both are brass). Does it means it has more copper in it? Do you have more resistance because it is longer? Which ones should I use?

2. In which order should I place the washers, the nuts and the ring terminals?

Thanks.

I just used some bolts I found in my garage, no special materials or anything. DMM reads 2.0 ohms. Pretty sure the material of the bolt will make a very minimal difference resistance-wise as long as they aren't coated with anything.

EDIT

Bolt head inside the enclosure, enclosure material, washer, ring terminal, washer, nut. Also a good idea to put a black mark on the negative terminal with a sharpie of small chunk of electrical tape.
