Kenwood Kac-9105d 1800 Watt Mono Class D Amplifier

First of all, I'm a BASS-head from more than a decade ago. After having a child, I thought all that was over with. Luckily, a friend of mine had a 12" Kicker Solo-baric (L7) in a ported box he just gave me because he was going to upgrade his system. I did some homework on amps. I was at first looking at the Kenwood 1000 watt amp but later saw the 1800 watt amp for just a few dollars more. This amp goes for $299 at Best Buy which boggles my mind!!! I was FedEx'd this within less than a week from California (I'm in South Carolina). My friend hooked it up in my 2008 Chevy Colorado truck with 4 gauge Tsunami amp kit and Monster Oxygen free speaker wire and my factory head unit (which requires a speaker line input). He hooked the remote through a switch he installed in the dash (we're law enforcement- gotta have a cut off). When I first turned it on, it went BOOM!!! He began adjusting the gain on the amp. I had to tell him, not that much!!! This thing has some power and it is beating up my truck really nicely. I listen to mostly rap, R&B, Old School, Rock, and Metal from way back (Metallica etc.) I'm very happy with the set up. Eventually, I'll get a head unit, but for now, I'm gitty!!! BTW, once he adjusted the gain, he told me to look at the factory head unit's EQ, the bass was on 0!!! That way, I can continue to bump up the bass as I slowly lose my hearing!!! Awesome amp, very worth it!!! Bumped for an hour or so the other day, amp was cool to the touch!!! It has 2 fans in it, to help with keeping it cool. GET IT, you WON'T BE SORRY!!! RESPECT YOUR NEIGHBORS and TURN IT DOWN WHEN YOU APPROACH...some day you may need their help!!! UPDATE: October 25, 2017- FYI- I’m still bumping with the SAME amp with my SAME speaker! Crazy! UPDATE #2: April 14, 2023- FYI- My 16 year old son is now bumping with the same amp and same speaker in a different vehicle! Wow!

My original set up was two 10" Kicker CVR in a Kicker Ported Box, wired parallel (so only one speaker input on the box) They're both a DVC 2ohm 800W peak and 500W rms. I had both wired at 2ohms powered by a Kenwood 800W amplifier, it was a pretty old amp. Whenever I would drive it a loud volume, the amp would overheat and hit protection mode, cool off and then turn back on. Even at low volumes the amp was extremely hot to the touch. Noticing this problem I decided I needed a better amplifier to suit my set up at a price that wouldn't hurt my pocket too much. I first saw the 1000W version of this amp, but then realizing I needed an amp with 1ohm capabilities I went ahead and ordered this one. This amp is awesome! I mounted it to the back of my box and it gives my set up a professional look. I didn't mess with any of the levels it was already set at, and I can turn up the volume with no problems! It pushes my subs nice and hard. Even after kicking for a long time, the amp stays cool to the touch with it's dual fans and thermal management system. GREAT BUY, I RECOMMEND.

IVE BEEN INSTALLING SYSTEMS FOR A COUPLE YEARS AND IVE GOT TO SAY THIS AMP IS BY FAR THE BEST I HAVE EVER HEARD FOR THE PRICE IT HAS THE BASS BOOST IS PHENOMENAL I HAVE 2 DVC 15'S 1000W RMS AND IVE GOT TO SAY THIS AMP BEATS THE CRAP OUT OF MY SUBS I MADE A CUSTOM MOLDED BOX FOR THE BACK OF MY MONTERO SPORT AND I HAVE BOTH SUBS DOWN FIRING AND OO BOY CAN U FEEL IT ANOTHER THING I LOVE ABOUT IT IS THE BUILT IN FANS THEY WORK SO GOOD YOU CAN HEAR THEM WHEN THE MUSIC STOPS YOU HEAR THE LIGHT HMMMMMMM I ONLY HAVE 2 NEGATIVE COMMENTS ABOUT THIS AMP 1 IT DRAWS WAY TO MUCH POWER I HAVE A STOCK 120AMP ALTERNATOR AND EVEN AT 3000 RPM MY VOLTAGE DROPS FROM 14.7 TO 11.3 WHEN THE BASS SLAMS OF COURSE BUT THATS WHEN I HAVE IT REALLY LOUD SO NOW IM LOOKING AT UPGRADING TO A 180AMP ALTERNATOR THE SECOND NEGATIVE COMMENT WOULD BE THAT THE AMP HEATS UP QUITE A BIT BUT SO FAR SO GOOD IT HASNT CLIPED YET I ALSO NOTICED THAT AT 1OHM IT GETS EXCESIVELY HOT BUT KEEPS ON PLAYING JUST FINE IT WAS TO MUCH BASS FOR ME AT 1OHM SO I JUST SET IT UP TO 2 OHM SO IT SHOULD BE GIVING ABOUT 900RMS TO BOTH SUBS GREAT AMP IM LOOKING INTO BUYING THE 1000 WATT ONE NEXT FOR MY WIFES CAR

basically long story short my tech level is higher, this is a great amp and is overpowered :P also i've owned this for 7 months, i run 2 crappy 12 kenwood duel voice coils of which you shouldn't buy ... this was my review on kenwood kfc xw1224D car Sub I RECOMMEND YOU READING THIS I PUT TIME INTO THIS.. SKIP STORY AND GO TO BOTTOM FOR NO STORY. - 'Overrated' these Subs are overrated and over-priced, My cousins 2 Dual 12s and them cheapo s have more Thump, more reasons below..or story rather, hah.. - 'inconsistent quality' I had the 2 subs hooked up @ 4 Ohm with x2 Kenwood Kac-9105D 1800-Watt Class D Mono Amplifier: http://www.amazon.com/gp/product/B0037ZRP7G/ref=oh_o02_s01_i00_details with 2 caps, then after i primed my system out with a good safe sub frequency ( how fast it moves, less the safer but less Decibels) Within the threshold of a good 30-50 Hz hit and then another safe nudge less so i do not have a muffling or over frequented sub, and the most Bass boost tuned without muffling the sub with some hard low deep hits all done great! i smelt a new smell Great! smells good! -34-38 DAYS LATER: (unknowing to me it was just the 1 sub stinking not both of them) Randomly i've noticed when i walked back in the vehicle that i thought it was the new smell but this smell should've gone by now and this new smell is kind've turning more into an electrical short out smell but not hardcore. -5-7 DAYS LATER THAT WEEKEND: Well i need to find out if i have dials wrong i thought and so i investigate, so i've tweeked it out and moved some dials and tuned it up a bit and what do you know its what i feared i smelt it horribly, so then i re primed the system back to where it was again and then some less.. -5-7 DAYS LATER THAT WEEKEND: I still smelt this 'smell' but more on the line of burnt out speakers or electronics, so then i tweeked with my system beyond the subs, amps, added another cap, thought it was the amps not enough power and it's shorting out because these subs never really did pump out the Db, Tried using 1 amp, tried lots of scenarios, including but not limited to no amplification from the headunit and only the amp, and vise versa, running another 0 guage wire from bat, bought a new cap, no bass boost...Anyhow lets just say i found the problem randomly working on it the next few days and it was a trial n error it was the one sub that was smelling burnt out so then I switched my subs to 8 Ohm. Reprimed my system, obviously i turned the dials up a bit further from prevous, anyhow this seemed to do the trick .. to a point i just cant Pound my subs for more then 3-4 minutes without stinking my car up.. that one sub is and was horrible, oh i didn't add but im not re editing in there, i disconected the other sub for a week with these new settings and no smell.. -November ( 2 months later and then some ) Same output setup, but both subs hooked up, basically same settings as i left it... I've sent a message to these guys on amazon asking for a full refund i wish i had the letter copied i didn't know till this day they would not respond.. well they didn;t respond, all i want is this 1 sub replaced.. i have bought all kenwood products, i don't even want to deal with these ... *** holes because i spent all this money on all kenwood and they don't even respond to tell me a negative response **** them -TONIGHT 1 HR 20 MIN LATER WRITING MY RESPECTFUL HONEST REVIEW OF THIS PRODUCT: well to this day i am never buying a product off kenwood and to this day i still have the sub but i spitefully turn it up and currently the subwoolfer is still alive and seeming doing well i haven't checked it since Jan, 4 months ago, the smell has gone down alot... in these past 4 months but i'm sure the output of that subwoolfer also has went down dramatically. I can tell from, my Rear view mirror doesnt fall off anymore to my song, but i don't care when they go I'll buy me some cheapo not from wall mart kids, online just some random cheapo 12 for 60 bucks total that's what you do.. this cost me 255 kids.. overall: VERY BAD CUSTOMER SERVICE ON AMAZON 2/10 , SUBS HAVE INCONSISTENT QUALITY I RATE 5/10 , IT HAS HIGHLY UNDERSPECED PERFORMANCE 4/10 ( don't listen when they say this sub a great bang for your buck because it performs with the 400 dollar subs) Lastly, IT HAS AN OVERLY OVER PRICED PRICETAG : 3/10 ( this is an 50 dollar sub, go to walmart instead ) I bought this not even 7 months ago and lol its down to 95$ i paid $255 for 2 kenwoods a joke.. I WANT A REPLACEMENT KENWOOD.. GIVE ME ONE IT STILL WORKS NO HARM DONE just SMELLS! and i'd say a 20% PERFORMANCE DROP

i purchased this item not to long ago, february to be exact and it worked great.its only been a few months and it has burned out already. it was only hooked to 1 speaker.i had this professionally installed so i know everything was done right. for the amount of money i spent on this item it should have lasted a long time. i do not recommend this amp to anyone, defiantly not worth the money....guess Kenwood does not want to stand by their name and either replace the system or refund the money I spent. DO NOT PURCHASE THIS ITEM!!!

I have this amp bridged to two 4 ohm 400 watt RMS 12" Kicker L3's. They are mounted in a sealed books in my 2000 GMC Sierra. This amp is powerful! This amp can push these all day at max power and not sweet. This amp is also gorgeous, in real life. These amazon provided images does it no justice. The amp is a beautiful metallic black, not grey as these images would suggest. This amp also has a cover plate that unscrews to expose tje wiring connections. Admittedly it was a pain have to remove this plate to install, but after words it looks sharp not seeing the connections. And not to metion the included allen wrench made it covenant. This amp also has the connections on one side. I think this was a brilliant idea! Having wires coming from both ends of an amp decreases the eye appeal. This makes it easy on the eyes and worth not hiding. The mounting holes are hiding on the back under the connection cover plate but the fronts are not. These are steady and work perfectly with the screws provided. This makes it nice not seeing screws in your set up. This wasy first amp and I am happy I went with it. Loads of power, great look, easy mounting. Overall a great amp.

Notice how the specs are rated at 14.4 volts in perfect conditions. No ones car runs at this voltage cleanly and consistently all the time. After you take into account temperature humidity, length of wires, quality of power wire... etc, you get much less. Really your cars alternator puts out 13.0 - 13.8 at best. So in reality your playing this amp at 13.0 - 13.8 volts and sometimes down to 12 volts under heavy loads. So instead of 500 watts your getting about 350w. This amp is overrated, or at least rated at un-realistic expectations. Also, this amp should not be run under 4 ohms. At 2 ohms it will over heat and shut down. If you match this with a 4ohm sub that's rated about 300-400 watts you'l be happy with it. Very cheap price helps make up for the complaints. If you got the extra cash go for a real amp like a JL 500/1 or 1000/1 who have very reliable performance and consist output across varies voltages and ohms. UPDATE: (July 3, 2013) After having the same model several times and other kenwood models, my opinion still stands. You will get a solid 350-400 watts from this unit so pair a 4ohm subwoofer to that power range.

I was looking for a powerful mono amp to power my 12" Rockford Fosgate Subwoofer. I knew this was going to hit hard, but after listening to the end results, I didn't expect it to hit THAT hard. I was blown away by the results and this is a best purchase I've bought for my system. After looking at some of the bad reviews this amplifier received, I start to question how people are wiring the amplifier itself. The wiring (if done correctly) looks really nice and clean, and you don't really run into an issue where the wires might interfere with each other. I would hire someone with a great deal of knowledge or experience if you don't know how to wire it. Putting that aside, the design is really nice as well. It compliments your Kenwood Head Unit, if that's the route you took. The center red indicator looks really nice at night, and it's just a simple way to tell if you're amp is getting power when you're setting it up. It has been a year with this amplifier and I couldn't be any happier. The amplifier stays really cool compared to other amps in the marker, thanks to it built in fans. I made a round trip from Sacramento to San Jose (about a 6 hour drive to and from) and it was still kicking. It can def take the abuse. If you're a bass head like I am, this is more than sufficient for a starting setup and can definitely be used for a more intense setup. Gonna order another one soon perhaps.
