Volfenhag ZX8300 on with radio, off with cd or mp3 player
I just installed this 1200 watt, 4-channel amp with a 1.5 farad capacitor, and 2- 1000 watt Volfenhag subs. I hooked it all up and everything seemed to be good since the subs were pounding with the radio on. I then hooked up my MP3 player to the aux in and the amp and capacitor turned off. I switched back to radio and after a couple of seconds, the amp and cap powered on again. So I tried a cd and the amp and cap powered down again. What gives?
All fuses are good, the ground is nice and tightly connected to a sanded down bare metal surface in trunk and the powere wire looks all good. The system sounds great with the radio, but completely shuts off for cd's and aux-in. Any ideas would be greatly appreciated, I can't seem to find much help anywhere regarding this amp. Thanks!

i have always heard that for ever 2000 watts you need at least 1 farad of capacitor. also once you hit more on the lines of 3000 or more you need a bigger alternator or battery and a capacitor is a must to keeping your amp running cooler and cleaner by keeping voltage drops to a minimum.
1 cap, either .5, 1 or 1.5 farad will be fine. they make 5 10 and 20 farad that cost way more than u need to spend for 400 watts RMS. i like the rockford fosgates, you can get a low cost Tsunami, just make sure you follow the charging instructions.
Like other car audio capacitors, the Volfenhag zx-hypercap has two terminals, a positive and a negative. The negative terminal is connected to the metallic frame of the vehicle (ground). The positive terminal is connected "in-line" with the amp 12V positive terminal.
The capacitor should be as close as possible to the amp. Within a couple of feet is acceptable.
The capacitor needs to be "charged" before connecting it directly to 12V positive. This is done with a 1000 ohm resistor and a voltmeter. The exact value of the resistor is not critical but it should be in the 500-1000 ohm range. Use at least a 1 watt resistor (your capacitor may have come with a resistor for charging).
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
