Re: my amp went into protect

See my solution for:,p424435/Eclipse-Car-Amplifiers.aspx And they shouldn't need a schematic unless they can't read the part numbers of the fried components.

Amp is in protect mode

If you have'nt fixed your amp by now I thought I'd tell ya a couple of things why it's going into protect. The basics. Blown subs, bad power suply or mosfets, and blown output transistors/mosfets. Still need help let me know. I repair amps for a living and i'm the cheapest you'll find and honest. I also give the longest warranty. I'm tired of other people rippin people off on repairs. Let me know.

I have a Jensen A600HLX hooked up to Rockford 12 and it keeps getting hot and cutting off. I have it mounted on the top of the box. What is wrong?

Make sure you are using the proper gauge wiring for your amp.

Is the amp set up in bridged mode? What is the impedance (Ohms) of the Rockford Fosgate 12? If the impedance of the speaker is different from the impedance for the amp in bridged mode, it WILL get hot and cut off. Also, if you overdrive the amp, the same will happen.

The amp is stable :
  • 75 watts RMS x 4 channels at 4 ohms
  • 100 watts RMS x 4 channels at 2 ohms
  • 200 watts RMS x 2 channels bridged at 4 ohms
  • 300 peak watts x 2 channels bridged at 4 ohms

  • Also, what model is the subwoofer? What are the specs? Is it single or dual voice coil?

    You can most likely mount a cooling fan on the amp and have it turn on using the remote sensor wire. If the amp still cuts out, you're overdriving it.

    Good luck and keep me informed!

    The amp is only putting out on 1 channel

    I do believe this is caused by one of your amp fuses. Depending on which + on the amp is being used. That channel has a blown fuse. have you tried running + and -, + and - to both channels to see if both subs worked? If one sub doesn't then it's a blown fuse or scarred fuse and needs to be changed.

    My xplod amp gets power

    If the power light is lit and the amp is not in protect mode, the power supply is probably blown.

    Have you confirmed that you have a good signal reaching the amp and that the speakers are not blown?

    Jensen A600HLX

    These solid state amps have no user serviceable parts inside them as everything is soldered into place and your gonna need to know how to use a multimeter to trouble shoot the parts inside the amp on the printed circuit board. Sorry But without the proper training and the right tools you could cause more damage to the amp if you dont know what your doing. You cannot just open the unit and see whats bad. You must test each suspected bad part and replace it as needed. You should take the amp in to have a pro look at it, as there is no easy fix on these unless its an external fuse, and a fuse will very rarely blow all by itself. Good Luck
