Hi, I'm selling a custom made enclosure created by CS Soundoff in Byram,MS for my 04' Subaru WRX STI. Any 10" sub rated for 1 to 1.5 cubic ft of space and preferably ported will fit. I had an older model Alpine type R sub in it with a 400watt amp. With a meter on it at CS Soundoff and just a song with decent bass it hit 136.I only competed in car shows with it, never any soundoff competitions,but I feel confident with the right set up you should be well in the mid to upper 140s. I did sell the speaker and amp separately knowing the custom enclosure itself would attract limited buyers. The pictures taken are of a friends 04 Subaru Impreza WRX since mine no longer exists due to a bad wreck. But there is no difference between the two as far as the trunk is concerned. I honestly dont know what other years have the same trunk and I'm sorry I didn't research that before listing this item,but please research and make sure it will fit your WRX Impreza if it is not a 2004. If you have any questions or concerns please message me.
