Quick question about gauges.

[macq32 10+ year member]

Hey guys, I have the following speakers set up:

Kappa 60.5cs (100rms)

Kappa 693.7 (110rms)

I was powering these with a Reference 475a amp and used a 4 gauge.

I blew my amp last month and am upgrading to a Fosgate Power 1000 25 to life 5 Channel amp (about 1400w)

I am also adding a 13tw5 to the D, so I am looking at putting about 900 watts through the amp. The amp suggests a 1/0 gauge. I am planning on adding a 2farad capacitor to the set up. I contacted a professional who suggested that as long is my gauge is a true 4 gauge, the 4 gauge should be plenty especially with the help of the capacitor. Agree or disagree?

Just trying to get a few more opinions on this!

I wouldnt get a capacitator because quite frankly their useless, get a deep cell battery...Since you already have 4 gauge setup in your car I would keep it, but it wouldnt be a bad idea getting 1/0 gauge incase you wanna upgrade later which u most likely will

disagree. read up in the electrical thread about the BIG 3. cap's ****.

if you have to buy new wire just buy 1/0 and don't use the cap.

Just buy a bigger battery

Thanks for the opinions guys

ok so im going to look into the Big3 upgrade, which im pretty unfamiliar with... so I'll weigh that out with the capacitor/new battery and read up a bit.

So here are combination's that would work (some better than others)

Upgrade Cell Battery, keep 4awg - I have stock 90amp saab alternator, is this an issue?

Upgrade to Big3, keep 4awg

Add Capacitor, keep 4awg

Get rid of 4awg, add 1/0awg

Is this right? these would all "work"

Now its a matter of what is best?

Still need to get rid of cap. They don't work, just upgrade your battery and if you can add a second on as well. For the alt questio it is always a better idea to get a higher output alt.

How would a batcap400 suffice? I went in another local shop today and talked with a few of the guys who were a bit more helpful with providing a few more options (assuming the information is correct).

Initially they agreed a 4awg should be enough, but after looking at the draw of the amp (250a) they insisted 4awg would not cut it and that I should go with the 1/0. The only problem there is that 1/0 and 250a is likely too much for my stock electrical to handle, so we left it with this being my best option:

I am planning on upgrading the Big3

I would replace the 4awg with a 1/0

And finally I would add a Batcap 400

I'm under the impression this might be the best way to go without replacing my alternator (for now anyway).

Does this sound like a good option to anyone?

Thanks for the help guys, much appreciated.
