I have rewired with 10AWG cablings (6 x 0.5mm threads) and have noticed a difference personally with just stock speakers... i used 99% silver as the solder direct joints also so there's no copper...
one of the idiot honda salesperson tells me the paint ' weak' cause of the lack of attention on the cu2 and that because the oz sun is stronger it will have a tendancy to fade out or bake quicker...
i can say that the fuel meter is not that great... today i was thrashing it around the metro (60km/h-70km/h)... at 3/4 tank had 550KM till refuel. Hit the m5 (100km/h-110km/h) and jumped to 660KM...
funny thing is i was on a pretty steep car park.. i let it roll backwards on neutral and no noise for like 50metres... as soon as i hit Drive and drove up the noise came back... i didnt try it in...
sorry guys off topic - does top one auto ever answer there phone? i rang sat ( 7 times no answer - maybe busy so left it after 11am) then i tried todayu 4 times and no answer... anyone dealt with...
