Amplifiers have thermal protection. They will typically shut down at ~180F. If your amp is shutting down after running it hard for 20-30 minutes, you may not have the correct load impedance (speakers wired incorrectly).

If it overheats as soon as it's switched on (no audio), the amp may be in need of repair.

I have 2 dvc 4 ohm alpine type r 15's and 2 svc american bass


Hi mate very nice amp you got there here is the specs for it



Model: MA Audio HK401SX
Hard Kore Series 1800 Watt 1 Channel High Performance Class X Car Amplifier
1 x 1800W RMS @ 0.5 Ohm Mono
1 x 1200W RMS @ 1 Ohm Mono
1 x 650W RMS @ 2 Ohm Mono
1 x 500W RMS @ 4 Ohm Mono
Fully Unregulated MOSFET Power Supply
2 Ohm Stable @ Mono
1 Ohm Stable @ Mono
0.5 Ohm Stable @ Mono

if you have 2 12s just bridge them and you will have 650wrms at 2ohm running to them or one sub at 4 ohm 500w rms ps they should pump iam running 2 12s with just 360rms at 2ohm and they do the job good luck

Rockford fostgate p500-2 amp overheating pls help!


Your Amplifier:
125W x 2 @ 4-Ohms RMS
250W x 2 @ 2-Ohms RMS
500W x 1 @ 4-Ohms bridged RMS

Your Subwoofers = Dual 4 ohm
Possible wiring configurations of (2) Dual 4 ohm voicecoil subwoofers are:

2 ohm Stereo
1 ohm mono
4 ohm mono


That amplifier is not 1 ohm mono stable.

You need to put a 4 ohm load on the "bridged" terminals of the amplifier

Your best wiring configuration is going to be Series-parallel.

4721108.jpg You can also get the same result (power) by having the subs wired in parallel independently. Put both + on one sub to one + on the amplifier and both - on one sub to the - of the same channel of the amplifier.
Repeat for channel 2.
This will be a 2 ohm stereo load.
You should only use this method if the subwoofers are in seperate enclosures... not one big cavity.

Not a problem just a question


  • 100 watts RMS x 2 at 4 ohms
  • 200 watts RMS x 2 at 2 ohms
  • 400 watts RMS x 1 at 4 ohms in bridged mode
  • stereo or bridged mono output
  • 4-ohm stable in bridged mode
  • Tri-Way capable
  • requires 8-gauge power and ground leads — wiring and hardware not included with amplifier
  • 50-250 Hz high-pass/low-pass (12 dB/octave) crossovers
  • wired remote included for fingertip control of Punch Bass (0-18 dB boost at 45 Hz)
  • MOSFET power supply and output devices
  • MEHSA mounting technology increases the heat transfer from the MOSFET output devices to the heat sink, for higher power output, lower operating temperatures, and greater reliability
  • TOPAZ — noise-killing differential inputs that eliminate 80% of ground loop noise
  • Trans•ana circuitry keeps preamp voltages low and signal paths simple for outstanding audio quality
  • NOMAD — advanced protection circuitry for "intelligent" shutdown protection
  • speaker- and preamp-level inputs
  • 11-1/8"W x 2-3/8"H x 9-7/8"D


  • Wire your sub in bridged mode (4 ohm mono)
    + to + on amplifier
    - to - on amplifier
    (using bridging terminals)

    Alpine PDX-4.100 3ch operation


    use channel 1 and 2 as normal, use the positive from channel 3 and the negative for channel 4 as mono 1ch, your bridged output on the mono chan should be around 200watts at 4ohms.

    Make sure your ignition signal wire didn't come loose somewhere. Was the Amp exposed to extreme heat?
