Well I laid the box down with the ports toward the drivers side now and it did a bit better, got a 140.4 on music this time and still no 45's I think it will just take some doing to get this truck loud but I think its do-able. As for Old school, I think I am pretty on par then to your setup as I am still working out the bugs and with about half the power and half the cone area I am almost 10 DB behind you...I think that's about right don't you? remember I have not taken the whole seat out or anything, and still need an alternator....Not to mention I only have a 4 gauge wire charging my batt for the amp too! It sucks it dry in about 15 seconds at max volume! LOL! Only a 1000CA batt too. I hope to get about 1 DB from the 45's hopefully and then I want to try a half piece of 3" PVC laid on top of the box to promote airflow up and out into the cab like I have seen a bunch of people do in the SUV's. Does anyone here have experience with this exact truck getting loud? I have been told it is very hard to get the crew cabs loud but I want to see what others have to say...
