I have a pair of sony bookshelfs (SS-CSPZ50 50W 6Ohms) that I have been using on my pc with a lepai mini amplifier(Lepai LP-2020TI). Yesterday i bought a used car amp (semtoni 300watt amplifier) This exact amp though branded semtoni. It has 4 channels each rated at 75W but 40watts continuous power. I tested one of my bookshelfs on the amp and it sounded so damn good. Today i also got an extra Sony Hi-fi speaker (SS-EX6) one rated at around 70 watts, 6Ohms. I tested the speaker and it also sounded good(i tested at low volume because it's at night though). Later today I get to test all the three speakers on the big amp. Do you guys think that my configuration is okay so far for a budget music/movie watching system? NB: I also have a cheap mini active sub-woofer that i plan to add to the set up once i balance all the three speakers.
