hey people.. well I ordered my 1 10" box and some people for telling me that the specs given by alpine to build a sealed box would make it sound like crap They recommend: gross volume range :0.5-0.8 optimum sealed box: gross internal:0.65 Net internal 0.6 Now my needs are for a sealed box as I don't want a bigger box in the truck,I do not want SPL, iam more SQL, I listen to metal/rock,not hard bass hitting rap. What do you people think and recommend? Thank you
