I have a 1995 Impreza GC8 coupe. Its (mostly) stock. Has a 07 sti spoiler, 07 full sti suspension, seibon carbon fiber hood, no interior (yet lol) full 10 point rollcage (like 9 now because i cut the bar for the drivers door) and a 5 point harness. For the system... Im working up.... I just got a smokin deal on 4 new alpine type s 12s (4 ohm) from a shop goin out of buisness. I paid 200 for all 4 brand new, in the shipping boxes from alpine! I went and bought a new hifonics 1700.1D amp to run them on. FOR NOW i have 2 in a store bought ported box in the trunk, and i just finished my custom dual sealed box for the other 2 for the back seat area. Looks dont matter too much for me for the build because my interior is stripped, so it looks kinda odd/bad no matter what. I have all 4 wired together in series/paralel for a 4 ohm load on each sub and a 2 ohm load on the amp. Still breaking in, so i havent maxed out to hear the outcome, but at half bass, and half volume, its giving me a little rear window flex and making my ears pop, so i have hopes! My next goal is to make a nice tuned ported box for the other 2. If that still isnt loud enough, ill throw 2 more type s in a ported box behind that on a seperate amp at 1 ohms, but this is what i have for now. Pics up later on!
