The speakers on the parcel shelf of my newly acquired new shape 00' wrx sti are pioneer TSA90 woofers with intergral amp the wiring to the amp is a thickish red wire with blue strip and a black thickish wire wish seems part of the wiring loom but testing the wiring there isn't any power does anyone know where these wires go I've traced them to a connector on the right hand side of the drivers seat they then disappear underneath.
