i noticed a huge increase in sound volume when i upgraded my system to a sony XAV-A1 (50w x 4 channels).
i wired it directly to the four wires going to the right & left speakers (i.e: im using only two channels now).
i must say the result is great, but i never dared to crank up the volume to the max.
am i overpowering the stock system?
any upgrades or rewiring i should do?
regards
