I would recommend this product because it puts out a lot of ampage for a low price. It's big but still has plenty of room. It does get a little hot but i keep mine loud and pumping for a long period of time and i use one to power 4 high end speakers. So, if you want them to stay cool get 2 or D class amplifier.
