Need advice on my audio system setup, not getting much power from my sub

[17tusol4]

Good afternoon, I have a earthquake subzero 10 inch 1,500 watt sub with a 1,600 watt kicker amp connected to it and I am running a 1,400 watt cable wire, I am not getting much power out of the sub, not sure if it's because of the low wire wattage or if I need to get a stronger amp, could you give me some advice of what the problem could be and how I can fix it or make it better, thanks


Running a 4 gauge copper cable from car battery to a kicker cxa800.1 amp

And from the amp I'm running a 12 gauge wire to the subwoofer both are aluminum wires

What vehicle? Box sealed or ported? Are there 2 amps? A 1600 and an 800?

Looks like that amp puts out 600 watts at 2 ohms which is what your sub can be configured for. I would get a higher power amp. You can run 1200 watts or so on your 4 gauge.

1999 jeep grand cherokee, box is sealed and the amp is 1600 watt with 800 rms and the sub is 750 rms

What's powering the signal RCA's to the amp?

1999 jeep grand cherokee, box is sealed and one amp, the amp is 1600 watt with 800 rms and the sub is 750 rms

Also will add that I had a kenwood kac-m1804 stereo amp installed to make my speakers louder

What amp would you recommend? 3000 watt?

3,000 will require an electrical upgrade and much bigger wire. You could get something like a 1500-1750 watt amp to have a little headroom. I bet you can push that sub a little harder than RMS. Put some power on that baby.

Could I get a 2500 watt amp if I get a capacitor if so what kind do you recommend?

Note my amp is 1600 watt max

If you go proper size box ported and properly load the port it will be twice as loud on your setup...night and day difference on your bass

No, forget about the capacitor, and 2500 watts is out of reach too unless you want to upgrade alternator and wiring.

I’d look for no more than a 1000 watt amp, but it must put out 1000 @ 2 ohms RMS. Don’t even look at “peak” or “max” wattage. And as suggested by @Louisiana_CRX , if you want max output, a ported box is the way to go.

I agree with CRX. Everything seems perfectly matched so best step is a ported box.
