Mono-Block A/B-Class GPV2000.1 1 x 500 @ 4-Ohms, 1 x 1000 @ 2-Ohms, 1 x 2000 @ 1-Ohm Maxx http://modesto.craigslist.org/ele/1185805883.html ive heard that the ground pounders are the only amps worth a damn from crunch,but not sure how true it is out of these which one would be better for a BTL at 1ohm in a 8cuft box at 34hz? i have a crunch power zone pzi1500.1 and i know it wont be enogh for it and probably does around 900 on a good day. thanks in advance

double baffle

ok sounds easy enough,but can i change the port to the center either standing up or laying down? and thanks for the help.

well thats the area i always get stumped on(how to find out tuning freq) i was told to use this box calculator http://www.the12volt.com/caraudio/boxcalcs.asp it has a slot port calc. but im not so sure on how accurate it is.

wow those are really nice designs. but i left out one piece of info(probably kinda important.lol)its going in a suv and was looking for a subs/port back setup. probably a stupid question,but ill ask anyways.would that same design work if i mounted the subs on the top and put the port laying down in the center of the back or along the bottom edge of the back?

what would be a good sized port?

its a box for two Fi 15 ssd's. the dimensions i have are 42"w X 20"h X 22"D total of 8.8cu.ft and total of around 8.5cu.ft with sub displacement. and a port 8"w X 8"h X 13"d would tune it to 32hz. thats the calculations i came up with,i just want to double check before i go cutting up mdf.
