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 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 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.

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 !!

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.
