[Here's what i did on my spring vacation from college in my 97 2.2, amp underplexiglass with neon in front that lights it up, 20"neon between the subs, then 20" lighting rod neon in back seat all controlled by switch in front seat, then subs mounted and installed in new boxes. i know this isn't much but i'm just getting into the custom interior world and didn't have the dinero for plexiglass just yet. tell me what yall think about it!!!!!

 

All cleaned and fixed...

 

i think, you should put a piece of wood covered in fabric the same as your trunk and cover that whole area except the amp housing. would be cleaner

 

not sure why u would want to subs firing at each other?
IMO i think you should get a Qlogic ported box made for 2 subs not 2 singles. it would sound much nicer and look much nicer. i never thought anything of those subs until i heard 2 12s in my buddys civic. wow was i suprised. cant beat it i think he got them for like 50 bucks a piece. but try ur luck with that qlogic ported box made for 2 12s.
