He's saying you broke the amp because you have no clue what you're doing, and your electrical is not up to the task...There is nothing wrong with any main stream amp if taken care of by a professional.
The words..2.5-3k...Reliable...And $350 do not work in the same sentence.
I suggest doing about a solid month's worth of research and studying. Put together an itemized list of every single nut, bolt, component, sound deadener, ring terminals...etc...Then start saving money.
I'm not trying to offend you but you are making poor, impulsive purchases at this time, and I'm trying to save you money by helping you take on your sound system with at least a small amount of tact, and strategy...
A 3,000 watt rms sound system is an enormous investment, and is not $350...A 3,000 watt rms system, including everything can easily run up into the thousands even using budget components like wire etc..
Whoever you are trying to impress will be there in 3 months when you are -- compared to today -- a total pro with an actual amount of money to buy a real system and more importantly the knowlege to use it..
