Dual 4 gauge to single 0 gauge adapter...

[bluemarvin3030]

Real simple, where can I find an adapter with dual 4 gauge in and 0 gauge out.

Looking to upgrade my amp. New amp will probably have 0 gauge input. I have two runs of knu 4 gauge cca and don't feel like switching out to single run of 0.

These are really nicely made and super compact. I need to place a Metra order soon and I can get one of these for you if you want one.

Issue is if your amp needs 0 gauge wire. There's a reason for this current capacity. 2 runs of 4 gauge cca can't handle the same current flow as a single run of 0 gauge. Do it right the first time. Done be lazy. You'll thank me for this in the long run

I really wanted to be lazy on this one.

Thanks, but mylows10 is right. I need to do it right the first time (well technically the 3rd time, seeing how I ran 4 gauge twice)

All I'm saying is don't set yourself up for disappointment

LOL that's funny ran 4 gauge twice I thought you had something else going on.: Mylows can hook you up with some OFC..

mylows10 is right. IIRC, two runs of 4 gauge, even OFC can't handle as much current as a single run of 1/0 OFC. I don't even want to know what it would do if both those runs were CCA.

LoL, they are both CCA. I'm gonna "invest" in 0 gauge ofc before I purchase and install a new amp.

The audio run and big 3 I got from Mylows was well priced considering he shrunk it and put terminals on.

OK. In a last ditch effort at laziness, I got one more idea. I will be replacing my battery soon. Will be getting a matching pair, one under hood and one in trunk (getting a sweet deal on two superstart batteries from O'Reilly auto parts.)

Could I keep the two runs of 4 gauge to trunk, connected to second battery? Then run 0 gauge to be amp when I get it.

Also would I need an isolater between the two batteries, they would be identical?

Help a lazy guy out, LoL.

Well, before ripping all your existing wire out it would help to know exactly what kind of ampacity you're gonna need. Four gauge CCA is good for about 100 amps so if your total current draw on both amps will be 10% less than that or more, then you can keep the wire you have and be fine. If not, then adding a second battery won't help because that battery will eventually run low and then the alternator will be stuck trying to provide current for the amps on top of charge current for a low battery.

Put simply, if your setup will be needing 180 or less amps then you can keep the wire you have. If not, you need to change it.

That's funny because I'm pulling exactly 180 amps now, 100 amps on the rf, 80 on the alpine. So basically if new amp is less than 180 I'm good.

Thanks for the advice. Not that I wouldn't replace the 4 gauge with 0 of I had to, just wanted to make sure I absolutely HAD to.

nah you're not pulling 180a constant. Music is dynamic meaning one minute, you're pulling 20a and the next you could be pulling 180

Keep what you have now, you're good
