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.

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.

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.

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.
