What amp for a Pioneer TS-W304C 12 inch sub


You seem to be looking for an amp made for car audio. There are many brands, but I going to give you the specs for your particular speaker which will help in choosing, not a specific name brand amp, but at least one with the proper power outputs/requirements.

Your speaker, based on the model number you provided, is rated at 4 ohms .Power handling range is 50-300 watts. And a peak of 600watts. That does not mean start cranking 600watts thru the speaker, it will blow. I suggest you acquire a single (mono) channel amp that provides 350-400 watts at 4 ohms.

Hope these specs help you in choosing an amp.

My sub wont play music but it will pop when i cut the truck on and the amp lights up


it's blown or the amp is. that pop you are hearing is the speaker clipping, meaning its getting power but no sound which means the amp or sub is blown.

How i wire my sub to my jbl gto301-1iiamp with 2 Hifonics HFi12D4


If the amp is 1200 watts at 2 ohm stable you will want to set up the speakers as parrallel and bridge the amp. That means conncect the speakers with + to + and - to -. Look at the amp connections. Usually thereare connects that look like this:
+ -
+ - + -

If yours look like this use the diagram on top. You will use the + for the left ouput on the amp to the right - on the amp. This will allow you to use all the power from the amp. Be sure to lower the gain as to not pop the speakers or amp.

I get a pop from the sub when the power comes on.


This is caused because the stereo you have put in, is a high power output, or higher than the factory and puts that extra power into the factory amp systems causing the amp to surge the power to the speaker resulting in the pop sound,most newer cars use a stereo system without an internal amp so as to reduce heat and a external amp in usually under a seat or dash and a high power stereo boost the output of the amp.

I have a rockford fosgate punch 150 and it will power a small 5 1/4" speaker, but doesn't seem to push my 15" subwoofer. I am reading 4ohms across the sub so I'm assuming that it is fine and that there is...


amp is way too small to power a 15 inch sub. But you should get some sound out of it, not silence. You can use a 9 volt battery to test your sub, if the sub pops when the 9 volt is placed across it's terminals then it's ok. If it does not pop then your sub may be bad, or the coil may be frozen. (It can still read 4 ohms if frozen). If your amp powers smaller speakers fine, you know it's not the amp. If the sub tests ok, then verify your connecting it properly to the amp's correct bridging terminals.

Zx-8400 amp too much for zx-4812?


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-

Subwoofers won't work and they are brand new


Hello,

I've got a pair of these MTX's subs powered from a Fusion 450 watt 2-channel amp. For the price, they are great. By the way, they are 4-ohm.

My first suspicion would be that something in the first incorrect wiring damaged either the amp or the subs. Can you explain specifically what the "installing the subs incorrectly" means? Was the amp output shorted out at any time or was it operated without a load? Either of these conditions will fry an amp and sometimes, the protection circuitry doesn't work either.

First make sure that your amp is still working. Check both the primary power fuse, usually located near the vehicle battery, and the fuses on both sides of the amp. Make sure that when you turn the system on, the power light comes on steady (blinking is protection mode). Test your subs one at a time on a speaker output.

Center speaker and sub stopped working


if the sub was popping that either means the sub is getting to much power and blown that normaly happens when they pop, for the center speaker could check the wires maybe it came undone that could be a possibilty

2 ohm dvc and monoblock sub amp


Yes. When you run two-two ohm subs to a monoblock amp its on the same channel meaning there ran parallel, and that makes it one ohm and most mono-blocks won't read one ohm. Are you popping fuses in the amp?
