Customer Ratings & Reviews

UnderRated for sure ..

I own both Boss CX1800 and the Boss CXX2705.
The CX1800 is in my 05 Aveo Hatch and the CXX2705 is in my 04 Durango. Both run Dual 12" Kicker CompD122 and the Aveo has PB 6 1/2 seperates and PB 4x7. The CXX2705 Durango has Kicker DS35 up front and Kicker CS674 in the doors and backhatch.
Both cars have dual batteries and a 2 farad cap. This amp does the trick. IMHO this Amps are very under rated. If you match your wattage with good quality speakers these amps seriously give much higher AMPS a run for there money. BE WARNED these amps do get hot. Install them in an open area. SO GRAB ONE.. YOU WON'T BE Disappointed

great amp

I installed the amp in the trunk of my 1968 Chevelle Malibu it sounds fantastic

Great 5-Channel Amp For The Price! Sounds Awesome!

I purchased this amp to replace my old two amps (one 4-channel and one mono channel), I had in the back of my 2007 Honda Civic. This 5-channel amp was exactly what I needed. It installed quickly, looks awesome, and sounds really wonderful across my 2 front component speakers, 2 rear coaxial speakers, and my single 10" subwoofer! Truly happy with purchasing this product for my car. I would recommend this product to anyone looking to switch from running two separate amps to power their system to only one.

Great value

If you need a 5 channel amp for a good price this is the one. Looks good and gives my Kicker speakers the juice they need to sound awesome. Would definitely recommend this amp to anyone on any kind of budget.

Great value

Im loving this amp. Now I need a better box

Great product

Excellent amplifier with tons of power. Does not over heat. Have used it to power two 6 1/2 and two 6 x 9 inch Kicker's. Subwoofer is 12 inch 800 watt RMS Kicker at 2 ohms. No problems so far. Have used a 3 Farad capacitor to compensate for power fluctuation if any. I highly recommend this amplifier. Great price also and nice looking.

Great Amp

This amp is perfect for my 300. I replaced 2 amps with 1, it has power to spare and adjustments galore. My 2 x 12" subs hit hard and the sound is crystal clear....and Loud!. Cant beat the price for a 5 channel amp with this much power.

Good while it lasted.

This amp powered one JLw0 and 6.5" db drive component speakers on my 2003 silverado z71 and lasted a little under a year before it went out. It sounded great and I really liked the five channel option on it but it was just not durable enough for me. Still a descent sounding amp for the money, perhaps I got a bad one.

Fantastic 5 channel high out put amp for the money

The amp powers 4 NVX VSP65 speakers in both the front and rear of car and a Pioneer TS-W3003d4 subwoofer . The gains are set at about 45% and at half volume the car just bursts with clean clear crisp highs , perfect mids , and slamming lows with 0 harmonic distortion !! I highly recommend this amp if you want high power to run your whole system with one amp . I know Boss is not top of the line equipment but the high output and the rave reviews sold me . You won't be disappointed . The only downside is the amp is huge !!

Great Amp, Great price, Perfect Configuration

I have owned my CX1800 for 4yrs. now, and I am very pleased. I am running Sony Explode 6x9's in the rear deck and Boss Audio 6" 2-way separates in my Century doors and a Pioneer 12" sub in the trunk. I thought the best solution would be a single 5Ch. amp- IF it had enough power and decent specs. The CX1800 was just the right solution. It packs 120WRMS x 4 into 4 Ohms- more than enough to drive the front and back speakers cleanly. And 200WRMS into 4 Ohms for the sub- again plenty or power. I was drawn to this amp (really not even being familiar with the Boss brand) strictly by the specs and 5ch. package of this amp. It has all the necessary features one needs to set-up a 5Ch. system like high & low pass crossovers, bass boost and a remote for the bass level if your head unit doesn't have a separate control for a sub. It's built like a tank. The sound is clean and accurate(my main concern) and can get more than loud enough for those volume junkies. My only complaint is that channels 1-4 only have a +18db switch for Bass Boost. This is way too much of a boost to be useful. +3db or +6db would have been more realistic. It should have been a Variable Control like it is for the 5th channel on this amp. With a sub you really don't need this switch anyway. It's a great value! I'm now a big Boss Audio fan.

Pretty good for being non-hype brand

Have Infinity Kappa 4", reference 6x9 and reference 6.5 and reference 10" sub. This powers it all and I don't have it turned up much at all!!! Very good sound but i am troubled b/c the shop that installed my items didn't run the cables clean. Had 4 different LOCsb/c of them. Slight hiss and distortion but I think its the route of the power cable vs speaker wires. Great looking and bass knob isn't one shown here in site, but works good.

Boss CX1800 - best amp for the money.

I'm powering db drive 6.5" and 5.25" component speakers and one 12" JL audio sub on my 03 silverado ext cab z71 with this amp and it sounds great. The only thing you have to worry about is routing the wires properly and getting a good ground point or you will get the infamous whining ground loops. Oh yeah, and the amp is huge, but if you dont care about space, this is a great amp for the price!

Nice Amp....

I purchase this 2700 watt Boss amp for my car, I wanted to separate the sound from all of my speakers. This amp did the trick. I can bring up the fronts while toning down the rear or vice versa depending what type of music I'm playing. I'd recommend this amp to others who have been looking at it, it works great and the price is reasonable also.

boss cx1800

It gets the job done if you have a budget ... I got a five channel but channel 3 and 4 didnt work ! I had to piggy back 3 and 4 into channel 1 and 2 . it still sounded great, but this isn't recommended to do.

I would recommend, but only if you are on a budget!

pros- good sound
cons- cheap quality

great amp

i have had this amp for a few months now. t powers 2 kicker subs and 4 hifonics component speakers and it makes the whole car shake. it gives crazzzzzzy volume. i would definitely recommend this amp

Great value, and very tough!

My dad bought this amp when we rebuilt our pontoon 2 winters ago. It runs a 12" Sony sub and four 6x9 Polk Audio speakers. It ROCKS. The stereo will make your ears ring. This amp has not missed a beat, and is exposed to wind, some rain, splashes, and extreme cold (we don't take it off the boat during winter storage, and our boat sits outside). It's definitely an attention getter. I'm very tempted to buy one for my own truck.

Hooked, now for the last thing left to get.....

First of all this amp is massive!! However I hooked it up and got it tuned and now am deaf! Not really but this thing blew my mind. I used to install stereos back in the day with the EQ power booster. This was so simple just get nothing less than 4 gauge and do the BIG 3 with the same and..... well if you are not getting this now what is your wait? Boss amp fan for life, now if I can find a in dash DVD I like then I will be set.

Best amp for less money..

I have had this amp for a few months now. great amp. for the job I was looking to do.

great ammp

I have had this amp for about a year now. Great amp. Never overheats, looks great, and plenty of bang for your buck!!

just what i needed

I wouldn't buy anything else. and it gets a beating with my off-roading, moisture without having a top on the jeep and volume always turned up.

Boss CX 1800 - Best Bang for your Buck!

I put in in my jeep, running all Polk Momo speakers and a 10in sub. Great power, clear sound, not a single problem. I wouldn't buy anything else. and it gets a beating with my off-roading, moisture without having a top on the jeep and volume always turned up.
