Earthquake speakers in sw20

[gordon77]

i was sitting in my car today with the stereo going, the car was off. and i noticed i could actually hear bass in the audio and it was very nice sounding had a look at the factory door pods and there was a speaker with earthquake written on the cone. i dont have a sub and i dont think there is an amp anywhere (obvious) however these these things pump an amazing amount of bass

anyone had any experience with these? should i be hunting round for a sub and amp somewhere?

AFAIK factory sub is in the box thingy behind the passangers seat. Some of us will be pumping 1250RMS into a single 10 for a bit more bass tho
