I am just wandering if I am wasting my time with my system, I want it to pound alot, I am getting ready to fiberglass my entire trunk. My subs are in 1.5 cubic feet boxes right now, which isnt enough and doesnt meet the minimum. The subs are 2 12" kicker L7's. I know these things hit alright but I want more. I figured re-doing the boxes with fiberglass will expand it to 2.0cubic feet a box. Also I will be adding a second 1200 watt amp, one for each sub. Do you guys think this would help me achieve maximum decibals / lots of bass? I will be adding a deep cell in the trunk and my old 2 farad cap. for the highs I only have a fosgate 400.4 and still using stock front speakers and 2 6x9's in the back in box's for now... My head unit is an alpine 7" touchscreen iva d300, its okay. Tell me what you guys think would be appreciated, just wanna know if im wasting my time on these subs.
