all these subs are around the $100 mark Getting an 8inch sub (must be cheap) to run in the factory location in my 2002 maxima. Help me decide. Here are the nominees Digital Designs 1008 300RMS, 60oz magnet. Loud but i hear low end extension isn't particularly good below 30hz but who's to know if that's true Audioque LW8 300RMS 80oz magnet. Not sure what design it's based off but they are made by digital designs (basically) should be very similiar to DD 1008 Crystal CMP8 around 200rms i believe. Also supposedly lacking below 30hz but good higher extension. IMAGE DYNAMICS ID8v3 around 250rms, great SQ. This is my top choice. Owned 6 ID woofers and never been let down. SQ is always right on and output on this beast is pretty good. Seems to be the top choice in this category by me and by others.
