Kenwood KAC-8405
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.

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!

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!

I have this powering infinity 6012 comps and a single image dynamics 10" sub. I had to fiddle with the x-over points and eventually had to turn on bass boost and turn my gain down but I have it set correctly now where I can crank my system and it is crystal clear. I had a 3 hour road trip and had my music cranking and windows down the whole time and no problems.
I elected to wire it up using the speaker cables instead of RCA and have no problems with popping. I can hear the fan slightly in the trunk after turning my car off but it's really not an issue.
This is a great little amp for a budget system and I am very happy with it. I wish it had more power but for what I paid I am completely satisfied.
