ya e30s steal bass due to that metal sheet
Im running 2 mtx 10's in MTX boxes powered by a 2 channel 600w (250 rms per channel) they pound pretty good but I wanna upgrade eventually, Infinity refrence fronts and a JVC deck its alright, I need an amp for my mids.
I also do not have rear speakers So sound travels through were the rear speakers were
From what I have heard I am not really impressed wit xplods there not horrible by any means but I think your paying to much for the word "sony". But since you are getting (or have) the xplod box with the xplod combined with the right amp they will sound as best as you could get em, cause in theroy sony should build an excellent box for there own subs...
