I am going to upgrade the factory amp that drives the subs in the parcel sheld. Working out the power wires will no doubt be pretty easy - but how can I identify L/R +/- speaker wires?

cheers

By looking at the colour of the wires going into the parcel shelf speakers

Thanks keeny - but I have worked it out - new amp installed and great results! As luke0011 suggested, I looked at the wires on the subs in the parcel shelf to get the outputs, , then worked out the inputs using a bit of trial and error and the head unit balance control...

the thing that surprised me is that there is no remote/accessory power.

Cheers

got a 4 x 75w amp - using 2 channels to drive the factory subs (as subs) and it's great - better than 6x9s IMHO. I am going to use the other 2 channels of the amp to drive the front speakers - using lpf so I can wind them up a bit without distortion and lift the front end.

Amping the factory subs is the cheapest/easiest mod I have ever done to lift a car stereo - I did it in my last car as well (VX Calais) THe wiring is essentially all there, and you don't need massive power to add a nice amount of kick.

Incidentally - the factory sub amp in the VY has adjustable gain on it - try winding that up for a preview of how much nicer the sound can be with a better amp...

i can do that on my vz too. but with the aftermarket 12 inch and amp it kinda doesnt compare. however id like a clearer sound all round and atm the subs in the parcel shelf do me no good. since the factory subs run tap off the rear speaker feed ill just add a 2 channel amp and 6x9s and hopefully that will give me what im looking for.

Turning the gain up will do nothing but make the subs louder at a lower volume on the head unit. Gain controls have nothing to do with power output, or sound quality.
