Replaced the OEM trunk amp with one channel of a Blaupunkt EM455 and took a bunch of RTA measurements of the stock sound system.
Looks like the door speakers have a 6dB/octave low pass around 600Hz. The dash speakers appear to have a resonance around 20kHz that takes a while to decay, but it's not too peaky in the actual response.
