Barrier Question

I am planning on building a box for 4 RE8 subwoofers for an 2001 extended cab GMC Sierra. The subs are dual voice coil and i will be wiring them for a 2 ohm load.

Like so,

My question is what is the best way to splice the wires of the subs? I have heard that a barrier, like this:

would be good to have the four subwoofers leads come in, and then out as one wire. My question is would this barrier be able to handle the load of power that is sent through it, or would it cause any problems?

Any suggestions are appreciated!

I would not use that barrier strip at all. What they are good for is connecting wire runs, not for joining together wire runs. Either solder all the leads together or use a power / ground distibution block like the scosche P48D. www.scosche.com

thanks forbidden, appreciate the quick response.

what guage would you recommend I use? there will be 175 RMS going to each sub. can i splice 4 12 awg wires and have it still go into a 12 awg, or do i have to use a bigger guage wire after the splices are done? do you have any references for splicing 4 wires into 1 like that?

thanks again

175 watts X 4 = 700 watts total.  Into a 2 ohm load, the most amperage the final wire will see is 18 amps ( https://www.the12volt.com/ohm/page2.asp#current) and 16 gauge will carry up to 15 amps;  14 ga. will handle up to 25 amps ( https://www.the12volt.com/info/recwirsz.asp)

Soldering four 16's to a 14 shouldn't be too much to heat with a good 100 watt soldering iron.  But it would be easier to solder them on one at a time.  Electrical tape would work best, tape each joint and then retape over the whole length of joints.  Illustrated here:

Pick up a wire loom at the hardware store to cover all the tape and give a nice finished appearance.
