nope..... do you guys know that you are the dumbest guys on this board? every thing i say you guys try to make fun of. lol but i could give a shit. i always try to give the best info to my knowledge. im sure ive installed hundreds of more systems than any of you talking shit. REASON i say nope is because my experiences with sub up port back in a trunk are not great. i found that sub back, port back is better for trunked cars that IVE HEARD. of course it is install dependant and there could be variables as to making sub up, port back sound good and have good output but im just stating MY EXPERIENCES. If you had elaborated on your reply in your first post instead of a one word answer, I'm sure that everyone would have understood you better, and not tried to "make fun" of you. Since on a message board the replies are conveyed as plain text with no emotion behind it, I'm sure that your answer could have been taken as smug or condescending. If you are trying to "give the best info" to your knowledge, try to make yourself a bit clearer next time. get real donkey. NOPE MEANS DONT DO WHAT HE SAID. thats that.
