Specs for Volfenhag 2500 watt 12 - Volfenhag ZX-4812 Car Subwoofer

the generator is not big enough to run what you want
it needs to be 3500w minimum or 4.5w to be safe
although it is stated at 2500 watts , in fact that is the peak load on electric motor start up and its continuous rating will be around 1.8 watts
all of this is clearly stated on the specs plate on the generator

try looking for mfg name, place where they were made, state or country, zip code, part numbers, any information here is a website

ZX 8290 Volfenhag 2 Channel 1200 Watt Bridgeable Power Amplifier

Volts x amps= watts.
20 amp breaker x 125 volts = 2500 watts.
However, electrician use the 80% rule, so multiply 2500 x 80% = 2000 watts.
So if you have 20 amp breaker, and 12 gauge wire, and 20 amp switch, and distance is less than 150 feet, then watt load is 2000 watts or 400 5-watt bulbs.
Keep in mind that most switches are 15 amp, and not 20 amp.
Recalculate for 15 amp switch = 1875 watts x 80% = 1500 watts or 300 5-watt bulbs.

I know this is really late. Hope it might help somebody. I just purchased a zx4810. For a sealed enclosure, 38L is recommended. Now I've got to convert litres into cubic feet.

Anythings possible but would not justify the cost of the upgrade. What be cheaper to get a new one with more watts.. No one really upgrades amps as the cost of new ones are so affordable.

The voltage prolly says like 100Mv-2v, it doesn't really matter, just know that that the lower you turn it the harder it bangs. The X-over depends on where your box is tuned, crank the knob down too about 40htz and you'll prolly be good, just don't turn it lower than your box's tuned frequency. And your rca's go to line input. And there shouldn't be a problem with mounting your amp vertically, you prolly just had a bad connection. Hope this helps if you have more questions please ask...

your Volfenhag 12" subs are rated at 1200 watts they are only 600 watts rms and the Rockford punch p4004 is only 200 watts rms so the answer is yes it will work but if you get a amplifier that pushes out 500 - 600 watts rms you will love the sound from subs
there is nothing wrong with the Rockford amp it just wont pound out the bass as hard but the good news is you will never blow the subs with it
when buying amps or subs make sure to look at rms rating that is the true power they actually have ie. (sub box says 1200 watt you think powerful but if you divide it in 1/2 you actually get 600 watts rms) don't get me wrong that's a nice rating. for a sub but you will want to match that number with the amps rms rating or lower. The RMS is what makes the car pound the higher the RMS the better
hope this helps
