The XM-ZR1852 amplifier afford incredible installation flexibility and packs quite a punch. ZR amplifiers offer tremendous value including convenience features such as: modern cosmetics, variable cross-overs, multiple channel configurations and singe-side electrical connections to suit almost any application.
I used this amplifier in an install and it was sufficient for the first 4 months of regular use. It produced great sound quality and good low range sound response. The amp ran two 10" Sony Xplod subs which each put out 380 rms. Obviously the amp wasnt suitable for the subs and it showed clear signs down the road. The amp started running through fuses and eventually one of the fuse housings melted. The amp was still use able until the power channel melted. Like I stated earlier it was the mismatch of power ratings that lead to the short life of the amp. Over all for the price it was a good buy, though I cant stress enough that it is important to pay attention to those rms ratings on products you purchase.
