Re: subs wont play
You first need to determine what is causing the "no sound" problem. (1) Try the sub(s) on a different amp (a friends maybe, or a local audio shop) and make sure that it/they work properly. (2) Test the outputs from the receiver. (3) Try a different pair of RCA cables. (4) Check the speaker wiring. (5) Check your head unit settings. (6) Check the amp gain. Once you have isolated it, repair or replace the defective wiring or part.

this sub woofer tube has a rms rating of 275 watts... try using a kicker or orion 600 watt mono amp to run this. the brand name is what tell you about how good an amp is for instance the names i just mentioned rate their amp by standard play frenquencies where as other lower brand names rate their amps by the max out put on certain subs at certain frequencies which may lower their impedance and create more power although you will never play your sub at those frequencies. as for the max power of your sub of 1100 watts that is more than like only at a certain frequency so always only double your rms rating of your sub to find max power handling.
you can blow a sub out when they are overpowered as well as underpowered. Distortion is the main reason thing go out. distortion occurs when you have the volume n the head unit up all the way and the gains on the amp are up all the way. always make sure the bass plays clear and you should be okay
Your KAC-5204 amp is only rated to put out 60 watts per channel and really cannot push very hard. If your subs are the KFC-W110S, they are 8ohm subs and you will get better power from the amp by using the bridged connections, positive (+) on the left channel and negative (-) on the right channel. Wire both positives and both negatives from both subs to the bridged connections and the output will be 150 watts into 4ohms. Giving each sub 75 watts should make them push a little harder.
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
1000 watt or bigger you always wanna have a little play room with the amp so it wont blow or short out. also if you do decide to add another sub....the amp will still be able to push both subs.. yeah so at least 1000 would be perfect but if you dont have the money about a 500watt would still push it hard. just make sure you have all of the options on the amp tuned to make it sound the best and make sure you have the right enclosure for your car. 500 would do...but 1000 would be best =)
putting too much power to the subwoofer......i just blew mine now.....it was a 1600 kenwood exelon 500 rms watt sub.....powered with insignia 600 watt 2 channel.......ran 600 watt rms though......cooked it ......so if you can underpower it....just bc it sez 1600w doesnt mean you have to match it just dont go over!
