Certified Output and Reliable Efficiency

High powered subwoofer applications tend to generate plenty of heat to the amplifier powering them. Music can only be enjoyed when an amplifier is on, and when an amplifier reaches high temperatures it will usually shut off to protect from it damage. The Kenwood KAC-9104D has built-in self-activating fans to protect from high temperatures so your system can play longer without having forced intermissions. That means even under stressful conditions, the built in fans will aid the heatsink to effectively cool the amplifier.

With an impressive output rating of 500 watts RMS x 1 Channel at 4 Ohms, and 900 watts RMS x 1 Channel at 2 Ohms, this amplifier is CEA-2006 compliant so all wattage specifications are true to industry standard. The Kenwood KAC-9104D also has the Capability for a 1-Ohm load to achieve over 900 watts RMS! Combined with their total efficiency and high power output, the Kenwood KAC-9104D is the perfect option for any compatible subwoofer application!

This amp is a BEAST

This amp is excellent. I upgraded "the big three" and installed a yellow top optima battery before I installed this amp because even though it is class D, it takes some juice. This amp will pound a crack in the pavement when combined with the right power supply and subs.I have put the pain on this amp and it only gets warm. This amp has NEVER overheated or clipped out. It is my opinion that if one knows what there doing, this is a cool running dependable amp that is a real bargain for roughly $200.00

Great Amp

This amp is awesome. For the guy who said it would go into power protect mode at 1 ohm its not that the amp can't handle it its your stock alternator not being able to keep up and your voltage is dropping to low thus sending it in to micro protect mode. Got this wired at 1 ohm to 2 Rockford Fosgate 12 inch p3's with a 220 amp alternator to keep up the power and all i can say is WOW. So in the future those of you who dont know how to hook up a system properly - DONT WRITE A REVIEW and TAKE IT TO A PROFESSIONAL TO INSTALL. Also its CEA compliant so its 1800 watts peak not 900 just cause you stand outside your car and think it doesnt sound like 1800 doesn't mean its not just means you need to learn how to hook up your stuff.

A top amp by a top brand with top quality!

You can't beat the value of this amp! Awesome specs, great price, and it matches my other amps. I plan to purchase another one soon for my current car!

Don't shop anyplace else!

Sales, parts, and shipping were all first rate. The products I bought from Sonic Electronix (KAC-9104D: Infinity 475a: Rockford Fosgate RFK4D: Rockford Fosgate RFI-20) all arrived very quickly and have been rattling the glass in my 05 Siera and bringing smiles to peoples faces, especially the women when they sit in the back seat where the subs are mounted underneath!!!!!

awesome amp, you guys dont know anything about car audio

this amp is absolutely awesome for the money. it will run all day and puts out great power. those of you who say it cuts out at high volume should check your electrical system. this amp has a built in dc current shut off. its shutting off because your electrical system alternator can't give it enough power. this amp is just saving your subs from blowing. get a high output alternator to fix it.

Very Good Product.

Only had this amp for about a week now but I love it. Im pushing a 12" JBL P1224 with it and it does the job right. Hasnt overheated at all, has the fan so i dont think that should be a problem. The look of it is very clean and slim. I would def recommend this to anyone.

good amp!!!

I just bought one of these amps a couple of days ago and i have to say out of all of the car audio I've owned this amp seals the deal. I am pushing 2 12" Pioneer champion series subs and it is amazing. I recommend this amp to any one who is looking for a big time bass.
