Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Contact Kicker to have them repair. .A thumbs up would be greatly appreciated if this answer is helpful to you.

Disconnect all the wires except the three main power wires, ground, 12v battery and remote. Now, turn on your radio, if the protect light is still on then there's an internal short in the amp. If the light turns green, then there's a short in either the auxiliary cables or the speaker outs. If it turns green, then troubleshoot the other wires that plug into the amp by connecting them one at a time until the protect light comes on, which will tell you that there's a problem with that speaker/aux wire.

  • yes you have a internal fault of the amp. the circuit that puts it into safe mode is bad and that is a very small chip on the board know as a op amp. needs to be repaired.

Hello jackstephens,

It's an either/or situation. The FE-402 can be set up to drive normal speakers in stereo, OR drive a sub when both channels are bridged. When the LP filter is on, it benefits the sub at the expense of the normal speakers. And with the filter off, the subs get the full range of frequencies and try as best they can to reproduce them. You might try running it with the LP on, in stereo with the 6X9's paralleled to one channel (2ohm load), and the sub connected to the other channel (?ohm load).

But my recommendation would be to use the Fusion amp the drive the 6X9's and get a dedicated monoblock for the sub.

Hope this helps.

I know this is a very broad statement, but your budget will allow for what you buy. You will want a nice 2 channel 50 watt rms amp min. 50 watts is a lot of power for those speakers and you will be happy. I would recommend if your budget allowed a nice kenwood, Alpine, Diamond Audio or MB quart. Just make sure whatever you buy that it is a low noise A/B class amp. Nothing to special.

Take care and have fun!!

Hello magoocsl,

Yes, with the use of 2 high-pass and 1 low-pass crossovers, that Kicker amp will operate in what they call stereo and mono simultaneously (SAMS). You'd run 4 of the 6X9's in mono. Wire them in series-parallel with a low-pass crossover on the positive leg to the amp. The amp would see a 4ω load. The other two 6X9's would be wired as stereo, one to each channel with a high-pass crossover. Again, the amp sees a 4ω load.

Here's a link to the appropriate wiring diagram. The diagram is on page 5. Just substitute your 4 6X9's wired in series-parallel where they show the "mono" speaker.

If going sealed I would aim somewhere in the 1.5 to 2.0cuft area. That sub can go in a 1.0 cu ft box to 2.4 depending on the room you he the bigger is usually better for sound quality

First, that amp, has too much power for that sub. Even though it isn't really outputting 2500 watts, (realistically putting out 650 watts). That sub is only rated to handle 150 RMS, 300 Peak, 1000 watts will blow that sub very quickly.

First thing you need to do is find a sub which better matches the output of your amp.

The second thing, you need to make sure that your vehicle's electrical system is able to handle the additional current draw.

Address these things before you install your gear.
