Kenwood KAC-8405

KAC Car Amplifiers

Reliable Output

An important element to class AB amplifiers is clean output with high efficiency. These two factors were highly considered in the engineering of the Kenwood KAC-8405. Highly rated signal to noise ratio and total harmonic distortion showcase this amplifiers signal processing and clean output. In some cases these factors wouldn’t mean much because the amplifier may generate plenty of heat over time and cause it to constantly shut off. In order to maximize total efficiency, the Kenwood KAC-8405 has had cleverly incorporated self activating fans to help quickly dissipate heat. This prevents damage to your amplifiers internals and also protects the amplifier from constantly going into self-protection mode.

With rated output levels of 60 watts to 4 Channels at 4 Ohms, and 90 watts to 4 Channels at 2 Ohms, this amplifier can truly output clean class AB signal without distorting and overheating. To achieve higher power output, the Kenwood KAC-8405 can also bridge two channels together to even power more demanding applications. This effectively allows the amplifier for 4, 3, and even 2 channel operations! Built into a compact, brushed metal chassis this amplifier even gives off an appearance of staying cool even in the harshest environments.

worth the money

I am very satisfied with this amp it didn't cost much for what you get out of it. The only thing bad about it is that it only has a bass boost on 2 of the 4 channels otherwise its great, best amp I have ever bought for that price range

Great amp, packed with features

I bought this amp about 5 months ago as part of a stock equipment upgrade for my Hyundai Sonata
It's worked flawlessly since. It's compact size fits under my passenger seat. I used the included speaker level inputs to hook into the stock stereo which was fairly easy with the included directions, but very time consuming.
I listen at high volumes quite often and this amp takes it easily. I have it hooked to Boston Acoustic components in the front and 2-ways in the rear. It's crystal clear. It also offers a lot of flexibility for tweaking your sound with the crossovers built in.
I've owned several Kenwood products over the years and have never had a problem.
I highly recommend this amp.

KENWOOD IS GREAT!

First of all this amp is well worth the money. I know kenwood is not known for their amps, but this is the second kenwood amp i have purchased and so far i like them. Don't get me wrong... these are great for the money! The settings are easy to work with and the amp comes with fans! i live in Las vegas and it gets HOT! the fans have kicked in but the amp has never gone into protect mode and im only powering some alpine type R's, makes them loud with out hurting the ears.

Very nice amp

Got this amp to power Polk DB651, and DB6501. Sounds are crisp, and clear. Absolutely no signs of over heating. Amp is still cool to the touch after an hour of solid play. Set up took about 20 min and I haven't touched it since. Great little amp!

Great addition.

I recently added this amp to my car and what a difference it makes. I have had my deck amped before but I do not remember it having the clarity this amp provides. Like all upgrades, I started with Kenwood Speakers. I can max out the volume and I still have clean and clear tunes. I had the volume all the way up and for the fun of it I honked my horn, and could barely hear it. I luv this amp. I'm saving up for a sub next. Looking forward to completing my upgrade.

BEST AMP IN THE CLASS!

This amp is one of the SMALLEST 4 channel amps i have ever seen...Not only the size but this is one of the most powerful in its size...this is my third amplifier on the setup i have in my car, Infinity Kappa front and rear and this little amp really kicks all the other out the window! I will buy another one for my other car, its that good....Most amazing 4 channel amplifier ive ever heard this size. To all other reviews that say it gets "SO HOT" or whatever, it says in the manual if it is not installed correctly it will over heat and it also states during normal operations may cause burns. so it is normal AND it DOES have twin fans. The only amp in its class that ive owned that does not shut down at too loud of a volume for long periods of use. These other reviews are very vague and do not give this amplifier enough credit and are only acceptable if they are comparing this to a 500$ Kappa amp which i doubt they have as they just bought one at 1/5th the price so if you ask me i would say they are amateurs that dont know how to tune an amp in correctly because trust me this one is worth every cent. I would buy 5 just for future cars if i could. 100% quality...kenwood out did their selves and sold me to all of their other products with just this amplifier! A sony xplod amplifier deserves the ratings from the others on here as this one deserves a perfect 5. (upgraded from an xplod 600w to this and yeah its that big a difference... this will NOT shut down crank it all the way up!

Kenwood value

I bought this amp to add a little bass to my basic setup. for this price level, it's hard to find a more powerful amp with a cooling fan especially important in Phoenix!
The sound is clean and there are ample controls on the unit for High pass/Low pass, volume level, crossover frequency etc.
I was disappointed that it did not come with a bass knob but the head unit I purchased has easy access to sub level so it wasn't an issue. I guess most people don't run these in three channel mode as I do.
Provides plenty of power for my Saturn and old ears. I recommend.

Compack

It's nice and small you can put it any where you want to if you don't want anyone to see it. And it's easy set it up not to complated is to wire it up and ajusted and your done and price you can't get no better that. So to me is very good and simple and thank you good day.
