Question about Volfenhag ZX-4812 Car Subwoofer
Just wondering if the zx-8400 amp is putting too much power to my zx-4812 sub, I have it bridged, it hits great, but every once in awhile it will make a pop sound, frequency is set to full and amp is all the way down on power, I dont know if it's just the box, because it has air leaks right now, or if its the sub..it doesn't do it all the time, and only does it on low notes, but yet never did it before with my 1200 watt amp...I'm thinking its the box, because when I look at the sub, when it makes that pop sound, it doesnt look like it's bottoming out or anything.
The amp and sub combo should work fine the subs can really take a crapload of power-i have a neighbor thats running 1200 watts rms to each sub in his caddy and OMG- its sick. Your amp should be pushing around 800 watts rms(continous) to the sub which should do very well-my concern with your setup is that the sub is designed for a vented box- you can use any box u want but im just suggesting that you use a good solid vented box with these subs- my other concern with your setup is that having only the single sub if its a dual coil 4ohm + 4ohm coils then you might run into trouble if you dont have it set up right-by that meaning to get all the power handling capability of the sub you would want to use both of the coils right? well to do that you have to either wire the coils in series or wire the coils in parallel right? In series the coils will yield an 8 ohm load to the amp and youll only get about 400 watts from the amp bridged into that 8 ohm load- on the other side of that if you wire the coils in parallel then the cols yield a 2 ohm load and that could cause the amplifier to become unstable and fry its little guts. All of this is assuming that the amp is made to run bridged at 4 ohms- if it is 2 ohm stable in bridged mode than you have nothing to worry about. Now the popping noise- that sounds like its coming from the amp somehow and just feeding through to the sub-like you ive never heard a sub popping unless its bottoming out and you say its not so its gotta be the amp id say-if it were me id check all power connections especially the ground for the amp . It could be that on the heavy bass notes that your amp is not getting enough juice -throw a 3.5 farad capacitor on the power line and see if that helps your system out-
