Kenwood Mono Amp Protecting

[Devil Tiger 10+ year member]

I have this Kenwood 9104d that when pushing hard for a few minutes, typical length of a bass test it will go into protect. I have it running on 4 gauge cable and a 1 farad cap.

Grounds are in a decent spot as well. Going to try it in my new vehicle but it's been tested in another truck with 0 gauge and different subs.

Anyone care to enlighten me on why it is still protecting?

What load are you running it at? The manual says they are 1 ohm stable, but in reality they really are not! Also, I hope you didn't set your gain hoping to deliver 900 watts to your subs because that amp will be producing distortion till no ends at that power level!

Look here for your "real world" power: http://www.caraudiomag.com/reviews/caep_0811_kenwood_kac_9104d_review/output_power_distortion_etc.html

Maybe you dont have enough juice going to it, or either your load is wrong. Those Kenwoods are picky at 1 ohm. Use to have one about one year ago.

You know it is bad when the local Kenwood dealer says their amps are garbage! About every 6 months of so that shop sells their Kenwood amps and speakers for cost plus 10%! The only reason they even buy the amps and speakers is because they are forced to purchase a certain level of product just to carry the Kenwood head units.

I've been thinking of upgrading amps to accommodate for some 15"s. Any recommendations at a reasonable price?
