Ok guys...I have my system hookedup now and it hits pretty hard. Haven't got it metered yet but the guy in Sommer sound systems in panama city beach florida who competes in the IASCA said it should hit mid 140's as it is. I asked him while I was down there if he thought he could fit a ported box for the two L7 12's behind the seat of my truck. He said yea, it would be a tight fit but he could do it. I told him that all the shops here in the BAton rouge area of Louisiana said they couldn't do it. He told me that that just means they are too lazy and don't want to spend the time to do it. I plan to go around to all the shops here and find me someone who could do it for me. The guy in Panama said he could do it for about 200$. If I went with say a 3.5-4 ft^3 ported box would it increase my spl by a significant difference? I would like to hit upper 140's to low 150's. Rick(of sommer sound systems in PCB florida) said it would be possible if you had the right box. i wish I lived down there because sommer sounds was a spectacular audio shop, they let me go back and watch them put the amp in, the sat out in the parking lot and helped me tune the gain and everything just perfect. I love the service they gave there. Here at home most of the people say yea give me you money and I'll go do it my way, they don't seem to care what the customer wants. So guys will it be worth the 200 or so to get the ported box? I just want to put it in for competition and leave my sealed box there for daily driving. Let me know what you guys think. And if anyone can recommend an audio shop in my area that is friendly and will do what I want, let me know! Thanks.
