Internal wiring gauge?

I promise, 14 vs. 10-ga. wire won’t make any difference for a 12 inch length. As Tony said, typically subwoofer manufactures don’t even use something as substantial as 14 ga. I mean, check this interior shot of SVS’s SB-12 sub. That’s probably 16-ga. wire at best.

Thats what I was thinking. I just found this cool site that calculates db loss.

According to that calculator, in this particular situation, even at 3 feet of 14AWG internal wiring, it would results in a voltage drop of .3 volts or .03db. 25ft of 11AWG on the other hand, which is a realistic figure for running from amp to subs, results in a 1.26 voltage drop and .14DB loss. So the 3 feet seems pretty insignificant.

I realized I overlooked something potentially more serious while while I was looking into this though, I was planning on using a SpeakON connector on the subwoofer like the one in the attached picture. It accepts 3/16th female disconnects, but I found out the Molex ones parts express sells are only rated for 10 amps. If I use 4 conductor cable from the amp to the sub and use all four poles on the male Speakon connector and 4 of those Molex disconnects, and then bridge both +'s to the + on the driver and both -s's to the - on the driver will each pole/disconnect only see half the total amperes that they would if I ran the same 1600 watts into two pins and two connectors? Is this still going to be inferior to soldering the wire directly to the pins? I don't solder but Im sure I could get someone to do it if its significantly better.

This is my first true DIY, so I appreciate the help.
