Hi all first time post with question. I have a 2004 Toyota Tacoma xtra cab and I installed a sony mex 100 bt that is supposed to have 40 watts rms x 4, JL C2-650 6 inch components 4 ohms in front and Jbl gto 6x9 in rear it is ok loud and clear when turned up to near max but I expected it to be much louder, do the speakers need more watts ?. I don't know if this matters I used the original speaker wires. Any info would be appreciated.
