Question about Rockford Fosgate T600-2 Car Audio Amplifier

1 Answer

Externally fused amplifiers

I've noticed that there are car audio amplifiers on the market without built-in fuses. Instead the manufacturers recommend external ANL fuses. What are the reasons for this? Are there hidden benefits or detriments in the performance of one product to the other? Is this to address the serious power fluctuations that particular amp could experience, or is it just laziness, and simple economics, quantity over quality?

I believe it's because the fuses (or any other connection point) is deemed to be a weakness. If an amplifier is properly installed, there will be a large fuse as close to the battery connection point as possible. Any other fuses in the amplifier itself would be considered redundant. From a safety standpoint, if an installer chooses not to fuse the main power wire to the amp the fuses in the amp will not prevent a fire from occuring should the wire get shorted. Therefore there MUST be proper fusing on the power wire and further fusing in the amp is not necessary.
The other reason for this may be that in many larger amplifiers from reputable companies (RF and others) they use un-regulated power supplies to get the maximum from their amps. Fuses could be considered a bottleneck in these systems as a properly installed system, again, has the required fusing at the battery.

Fuses amp


Yes, your amplifier needs the amout of fuses as there are fuse ports.
In case something were to go wrong it would blow the fuses instead of your amp and subs and burning your wire harness up..

I hope this helps.

Were is the fuse located on the punch 300s?


I just read all the information about this amp on crutchfield and never saw anything about a built in fuse or external fuse. I don't think it has one.

Have you checked the fuses inside the amp?Unscrew the cover and with the amp sitting on its back,remove the cover.You have 2-4 fuses,old round type,in there.

Where are the fuse on this amp?


The Tantrum 1200.1 is externally fused -- there is no fuse within the unit. Per the installation guide, it should have an 80 amp fuse between the amp and the power source.

Amp was hooked up without fuse from battery to amp


Another failure must have occured, as the fuse would have blown, possibly limiting the damage, however something did fail to start the problem.

Nobody can give you an honest estimate without analyzing the damage.
A wild guess would be one-half the cost of the unit.

Cant find out where the fuse is in the amp.


Hello willflo,

All of the information that I can find on the JL products indicate that their amps are fused "externally". The 500/1 needs a 50A external fuse.

Hope this helps.

Ground zero amplifier overheating and going into protect.


Since you changed the amperage of the fuses and the cable, you allowed the internal problems of the
amplifier to get worse than they were before the original fuses started blowing.

A fuse is a safety instrument that blows instead of your amplifier.

The problem is NOT the fuses frequently blowing, as such events warn you of internal problems with
the amplifier which you should have had serviced at the time to prevent them getting worse.

It is very much like the persons who replace the fuses in their household wiring with pennies, to prevent
frequent fuse replacement only to have their house burn down from overloaded circuitry.

Service your amplifier immediately.

Revert to the original amperage on all fuses in your vehicle to prevent a car fire.

Trying to power a amp with 16 volts. possible?


Golf carts do not have a charging system. If you are going to use battery power only, why not just add (1) 12V car battery instead of (2) 8V??

MA Audio runs (ran) their bench tests @ 17V. All the power ratings advertized are at 17V.

The power supply for the hk4000D is unregulated. So the more voltage = more power.. 8V-16VDC.

  • RMS Power @ 14.4V
    • 1800W x 1 @ 4 Ohm
    • 3600W x 1 @ 2 Ohm
  • RMS Power @ 17.0V
    • 2000W @ 4 Ohm
    • 4000W @ 2 Ohm
    More input voltage means the amplifier will have to work less hard to make power.
    Don't expect the amplifier to work for very long however. the current drain on a class D amplifier is huge. There are no on-board fuses protecting the power supplies, so be sure to have at lease a 150A power line fuse.
    With 150A current draw - even with the amplifier at 1/2 gain - expect to get 10.6 minutes of listening time from your 16 volts before recharging - also note, the amplifier MUST see 8V to turn on, there is a built-in voltage sensor that will shut down the amplifier if voltage is too low.

    ROCKFORD FOSGATE Punch 301M Amplifier Problems!!!!!!!!!


    Check the Inline Fuse -=Usually located Close to the battery in the engine copartment=- and also check the fuse in the AMP. Without knowing and seeing all of the details i would say to try to bypass the capicator, I know that i always unhooked my inline before jumping the car but i know it happens. Hopefully it will be just that a fuse or the capicator but if some sort of surge resulted from multiple failures get the amp bench tested at A car audio shop. Just some thoughts.
