Yup, everything runs off a stock Nak amp. The sensitivity of the stock paper wizzer speakers are likely really high (higher than the 93db bostons since even they didn't play as loudly). I'd recomend the older Boston Rally components as they sounded really good. It's difficult to find 4" components. Mine were direct drop into the door speaker pods. The rear deck can hold upto 6.5" speakers with modification to the plastic speaker pods.
