you might need to see what your volts are if there 14.4 at the amp thats good but see what they drop to ....

SOURCE: dual voice coil wiring to class d amp

The easiest way to think of wiring voice coils and subs is this:

  • Two items of the same impedance in parallel = Half of the impedance
    • 4 ohms in parallel with 4 ohms = 2 ohms
    • 8 ohms in parallel with 8 ohms = 4 ohms
  • Two items of the same impedance in series = Double the impedance
    • 4 ohms in series with 4 ohms = 8 ohms
    • 8 ohms in series with 8 ohms = 16 ohms
In this case, you want to wire two subs, each with dual 4 ohms voice coils, so that the total equals 2 ohms. Your options are:
  • DVCs in parallel, 2 subs in series = 4 ohms
  • DVCs in series, 2 subs in parallel = 4 ohms
  • DVCs in parallel, 1 sub = 2 ohms
With two, dual 4 ohm subs, you can only have 1 ohm or 4 ohm total impedance.

SOURCE: Kenwood KAC-9152D monoblock

The amp says it's 1 ohm stable, so assuming the DVCs are dual 4 ohm, you should be able to connect all "+"'s together and all "-"s together, like the picture below:

As for the amp shutting off for a few seconds, it sounds like it's either:
A) Not getting enough power at high volume.
OR
B) Overheating.

The cap on the +12V to the amp should help, but putting a meter on the +12V might tell you whether it's dropping too low (<11V).

When you first turn the volume up, how long does it work fine before shutting off? Is it with the vehicle running or not?

SOURCE: my amplifier keep clipping

start with the lowest settings on all the adjustment knobs and turn your radio up to about 3/4 of the volume and go from there

SOURCE: How do I hook up my infinity 1600a at 2ohms with 2 4ohm speakers?

Placing the speakers next to each other face down, you will notice that the connection points run in sequence +- and +-. Now connect the - (negative) from the one speaker, to the + (positive) of the other speaker. Now connect the open + from the one speaker and the open - from the other speaker to your amp. Your amp should have a bridging indication. On the connection points of the amp, you should see a mark pointing to the first + and the last -. That will be your bridge and thus utilizing the full potential of your amplifier

Can i hook this amp to my home sound system

Technically, yes, but there are some challenges. First, the input voltage to the amp is 12VDC, not 120VAC. You would need to find a power supply large enough to supply 12VDC at 30-40 amps (plus has proper currently limiting or fuses to protect against overloading). Second, most home speakers are 8 ohm impedance. While the amp can power an 8 ohm speaker, the output power is cut in half (compared to a 4 ohm speaker).

I have 2 10" Kicker Comp Subs

That amplifier is only rated at 150 watts at 4 ohms, or 300 watts at 2 ohms. Not a very strong amp to run 2 kicker comps. My guess is you have the subs wired wrong for your application. There are 2 types of subs, one is a dual 4 ohm, and one is a dual 2 ohm. Most people bridge these coils together and that cuts your ohms in half. For example. Lets say you have the 10cvr104 subs. Thats the dual 4 ohm sub. You wire the coils together in parallel, now its a 2 ohm sub. You have 2 of these subs running off of your amp, if they are hooked up in parallel, now you have a 1 ohm load, out of the amplifiers normal operation. Your amplifiers internals heat up really quick and there is a thermal overload, putting your amplifier into circuit protection mode. My suggestion for wiring your subs is as follows: for each speaker, wire the coils together like this- positive coil1 to negative coil 2 and negative coil 1 to positive coil 2. That is called running in series, and doubles your ohm load. Next, we need to wire the speakers together properly to hook up to your amplifier. For this, since the coils are hooked together, you only need to use one set of terminals from each sub. And take the positive from sub 1 and hook it to positive of amp. Take negative sub 1 and hook it to positive of sub 2. Take negative of sub 2 and hook it to negative of amp.

Amp burned out but fuses still good?

this is caused by inproper wiring from the speakers/subs to the amplifier.. an amp will still put out power to subs and speakers when it's wired improperly but it won't last for very long doing it... 6 months is longer than usual....

MA Audio MA 1200XL Car Subwoofer

that subwoofer has dual 4ohm voice coils, if your amp can handle 2 ohms, you would put a wire from the positive (+) on the amp to the positive on both connectors on the sub, then hook the negative (-) on the amp to the negative on both the sub connectors that will be a 2 ohm load on your amp make sure your amp at 2 ohms is not more than 600 watts RMS or 1200 max.

Amplifiers

It sounds like you've got too little impedance on it. How are the speakers wired? Are they in series (one speaker per channel) or are they in parallel (speaker 1 neg wire hooked up to channel 2, and speaker 2 neg wire hooked up to channel 1)? Or do you have a single speaker bridged (pos wire on one channel, neg wire on the other)? Often, an amp going into protection is a result of too much current draw, which happens when you're running a 2-ohm load on an amp that isn't rated to handle that (many are only OK at 4-ohms, which you'd have with series wiring). Let me know how you have the speakers wired and we'll go from there.

Ma120xe sound horrible

Make sure that you have the subs wired in a 4-ohm series and not a 8-ohm load

DUB2502 amp

you probably have the speakers set to where it ecxeeds the ohm load limits. its only 4 ohm stable when bridged and two ohm stable when ran using two channels. so either run the speakers at 8 ohms each parallel or just hook one speaker to eack channel. if you do not know what i am talking about then just email me at [email protected] and give me the speaker specifications.

Im not sure how to hook these speakers up

answer depends on what kind of Ohm Load your amplifier is capable of as a lowest allowed setting. ie if you have a 1400W at 4 Ohm amplifier, the connection would need to be different than a 1400W at 2 ohm amplifier. also, on the speaker what is the rated ohm load per coil since it's a quad coil speaker (should say somewhere on it's box, or in it's manual. I'd assume 4 ohm per coil) we'll do that math after you get those figures in to me.
