my other car was totalled, now got another civic hatch. I had 2 L7 15's downfiring in my backseat in other civic coupe. It was plenty loud but i had already sold it all when i got this car. I drive car daily and probably wont compete unless at local show. I either want to run 2 15's again or possible 4. Question is, would they be louder in the hatch facing up or back, or walled off to the front? thanks
