0 gauge power and 4 gauge ground?

[Z4CK 10+ year member]

I'm going to be using a AQ1200d and since it only accepts 4 gauge i'll be using a reducer from the 0 gauge power to the amp. I was wondering if I could use 4 gauge for the ground to the car, would this cause any problems?

probably won't be a problem, but why is your ground 4ga. and power 1/0? you should fix that disparity as soon as possible

I'm not doing it right now but I was just asking if it would be okay because im trying to save money, it would probably look ghetto so nevermind i'll just go with 0 gauge and 2 reducers.

earth and pwr wire should be the same gauge

ALWAYS keep power and ground the same size , unless you want a blown amp...

You're fine the way you are. You shouldn't have any issues. The amp is designed for 4 gauge so using a reducer on the power and 4 gauge on the ground will be fine.

As it has been stated above, your ground wire should be at least the same size as the power, you can go w/a bigger ground too as long as the power and ground wires are the required size.

ummm yea there can be problems. there will be less resistance getting power and more for ground, amp could last 1 week,a month or forever but isnt a good idea...

Not "right", but not a problem.

Whether it's 4 ga, 1/0 or 4/0...there will be a small amt of resistance there, just as there is in the power wire.

4 will have more than 1/0, but still acceptable for that amp. It does kind of defeat the purpose of running the 1/0 on the (+) side though.
