Good Amp for the money
I bought this because i needed a 4 channel in my truck. I went against all reviews saying that the onix series from MB Quart sucks and doesnt put out what its recommended, but i tested this amp with a DMM and after calculations i found that it puts out about 85-90 rms at 3.3 ohms. That is a great for the amp only costing $150. This amp is working well for me making my truck sound great. would def recomend this amp for anybody on a budget. if you have more money to spend then use it cuz there are better quality amps but i like this amp and will have it for awhile. Dont be afraid of the amp getting too hot because class AB amplifiers get hot. if you need one to stay cool then get a Class D amplifier, they are more effective so the energy isnt wasted and turned to heat.
