WHO'S THE BOSS??? THIS ONE!!!
Boss is a mid-range mid-grade product. Through out the years, I have always somehow found myself purchasing Boss products. For the money, you cannot beat the product. If installed properly, It can give you years of service without problems. I installed this little monster on 2 Boss 12"s, Which my cousin laughed at me for being "cheap" because he has always had fosgate and infinity products. But, his smile soon turned into a frown when I pulled up to his house and my "CHEAP" Boss speakers kicking so hard they were knocking pictures and Clocks off his walls. Which boils down to this- Boss is a solid product, and has been around a long time. Don't listen to people who don't know anything about car audio. Do your math- and figure out how much you want to spend- And install BOSS- YOU WILL NOT BE DISAPPOINTED!
best amp for the price
this is the best amp your going to find for 100 bucks I got 2 of them 1 for each speaker that are wired at 1 ohm a piece and it hits hard your never going to find a better 1 ohm stable amp for the price

great amp for the money!
Great amp!! Only complaints are it gets warm pretty quickly and two is that it takes small wire I got 0/zero gauge and that was to big but I made it work! Other than that love it it makes my pioneer 12 in. Champion series bump!
