http://sonicelectronix.com/item_6835.html# I know it is cheap, but I'm not looking for an awesome system or any subs at all. I just have 40 RMS Watts 6x9's in the back, and 50W 6.5's in the front. That's all I want, and I just want it to sound good...so will that work?
I think id spend a little extra money and go with the Crunch pzi 100.4, which on that website is the next amp after the one you are looking at. Crunch is made be the same company that makes Autotek, MB quart and Hifonics, which are all solid, well made amps, esp the mb quarts. even though its thier bottom line stuff its leagues ahead of boss audio and its only 30$ more.
I too would steer clear of that amp, It would work, but is not the highest of quality, spend a little more on something more durable and a little more powerful, you will be much happier.
even the lowest priced amps from a good line will be head and shoulders above even the highest priced cheap stuff.. if that makes sense.. go for quality.. yes the boss will work.. it has a warranty, but how much do you want to spend on postage in the next year?
