if i was you... i would if you looking for some decent bump.. i would get a good monoblock, and a Type R in a good portd box.. shouldnt break your budget.... then get some better frontstage, along with an amp if you have the money to get it.. and if you getting bad sound from the hatch with the system you got... then i would recommend some sound deadening... makes a world of differnce.. i dont know if all this fits in your budget.. but its something to look at
oh i didnt see that you were going to go with all audiobahn.. one thing that you will learn is that audiobahn isnt to liked on this forum.. they are overrated.. i would personally look at differnt 6x9s and amps. and subs.. and any other thing audiobahn... sell it all to some kid that loves the chrome and flames for a good price... work a little and get something worth the money
