astrochex first ever build - MINI Cooper S

[Hic]

If the fuses are matched to the size of wire you are going to use , you're all set.

copper wire

4 gauge = 60 amp

8 gauge = 30 amp

12 gauge = 10 amp

thank-you Hic.

[Hic]

Your welcome

Not progress, but another dumb question.

The Helix manual says the amp is rated at 4 Ohms bridged: 1 x 360/600 W. Since the subs I am running are 8ohm, would I half the ratings for the 8ohm load?

The pic shows the 4ga wire I was planning to use for my Helix amp. It looks like a very tight fit. Helix says that 16mm is the minimum cross section for power/ground wires. I am going to ask them what that means in layman's terminology.

[Hic]

Yes , as your resistance increases your flow rate decreases.

Feel free to pare down or shave some of the copper wire down to fit the opening.

cross sectional area in millimeters appears to be around a 5 awg, so just put an edge on a knife and whittle the 4 awg down.

If you have to you can cut some of that wire out if it DOES NOT fit.

I usually just hit it with strippers to the size it need and then peel the excess wire strands out

[astrochex]

I never would have thought that would be a kosher thing to do. It saves me from having to get new power wire.

Thank-you all.

How many subs ? and how will they be connected ?

If you go from the 'red' or 'positive' post to the positive or red connector on 2 subs.

Then go from the 'black' or minus to the black or negative connector on each of the 2 subs

your amplifier will see a total load of 4 ohms.

[astrochex]

There are two 6x9 subs. As you say and as I just confirmed from 3yr old emails, the amp will see a 4ohm load. The connection diagram I was given is shown.
