Check your amps ground and make sure it has a clean connection to the chasis. If there is paint or any kind of coating where you are trying to ground, use a steel brush to expose the bare metal. Also, make sure you are grounding the amp directly to the chasis and not to another grounded wire.

Hope that helps.

My teac ag-680 fuse keep blowing everytime i replace it and plug the reciever up


are short in the audio output transistors may have been short since a channel 2 or maybe 4, also open resistance check carefully and change them after you put a 75w bulb in series 100w or where is the fuse clearly, you have to remove the fuse when you put the focus if all is well will turn on only a small incandescent and amplifier work well you put audio speakers and there will, if everything is well put the fuse back and ready.

The internal 1.6 amp fuse in the power supply sometimes blows on or after switch-on.If the fuse does'nt blow the amplifier appears to work as normal on low volume.


check your wiring and the speakers for shorts...also, you need to look at the back of the amp..there should be an impedance rating for the speakers..it will be in ohms...if your speakers are lower than the rating on the amp then the fuse will blow as this causes the amplifier to overload..if the amp is rated for 8 ohms and you connect 4 ohm speakers this can cause this issue

We have a Rockford fosgate p3002 model. The amp fuses keep blowing and the protect light is on.


It most likely has a blown channel. It is going into the protect mode. If you have a multimeter I can guide you thru the process of figuring out which channel is blown and how to repair it. It will require, as noted above, a multimeter as well as a soldering iron, solder, solder wick and then the purchase of the bad parts. If you do not have this equipment there is no way for you to fix this yourself. You can always take it to a service center for repair if you are not able to do it yourself.

I have fixed many Fosgate amplifiers and can assure you there is no easy fix for your amplifier. It will require the replacement of parts.

Let me know if you are willing to try it yourself and I will help you as much as possible.

Peavey 1200 Amplifier


Some of the outputs transistors is bad hence causing a bridge in circuit,thats why the fuse is blowing.Check all the outputs transistors on both channels,rectifiers and zena diodes these are the possible causes of circuit bridge when they are faulty.The fan works on AC thats why it is not affected even when the fuse is blown.Please if you have anymore challenge please send me a mail on mikewee4wee@yahoo.com

How to install Rockford Fosgate 3sixty.1 to a Toyota factroy head unit?


You will need a line level adaptor to get an audio input for the amp.

A line level adaptor is a device that lets you tap off of your speaker outputs of the radio and it converts that signal into the proper level for an RCA input signal the amplifier uses.

If you are installing the amp in the trunk of the car you can just tap off the speaker outputs of the rear speakers mounted in the trunk. Keep the speaker outputs connected to the speakers, just run an extra set of wires from them to the line level adaptor. It will not take anything away from the speakers sound because it is not a power drain on them.

After that, you just connect the power wires for the amp as you would normally and you also need to run an extra wire from the radio power antenna wire to the remote turn on of the amp, or you can use a wire directly from the battery and connect it thru a switch you would need to connect somewhere around the dash, so you can turn the amp on and off when you need to. The power antenna wire from the radio is best, so you don't need to turn the amp on and off manually. It is easy to forget about turning it off sometimes and that would run doen your battery if the amp is left on over night even with no signal going thru it.

Then connect your speakers to the amp and thats it.

Then big issue is getting an audio signal to the amp and the turn on signal for the amp.

If you need more help let me know,

some decks save different settings on different sources. Make sure that the bass settings are not up higher on the radio sources and lower on the CD sources.
