help with my sub guys!! (fixed it)

ok, i have an alpine cda 9884 HU, a profile 1000 amp and an alpine 12 type e. the amp is 310w rms at 4 ohms so its the right choice im not asking that. my HU has an rca output for a sub so im running that to my amp, like the HU owners manual says. i turn on the power, my Hu turns on, and the amp powers up, but theirs nothing coming from the sub. the wiring, amp, and rca's are all brand new tonight. the sub is used, and my hu is only a few months old. WTF?! is up? plz guys, i was so excited, and i was till about 10 trying to get this to work, and ive got a major cold already lol. i pulled the sub outa the box and checked the wires, all good their, i put a amp meter sett to wattage and checked the output on the amp to the speakers and got nothing. im guessing either my brand new rca's are bad, or the rca out on my hu is messed up which i hope isnt it. ima pull the rca off my dvd player in the house and try it just to see. help me out if you can guys lol.

subs prolly popped ...hymmm

theirs a stupid tiny little switch on my deck the manual says nothing about, that fixed it lol. now if only i could tune it right haha.

glad you got it fixed. its always the stupidest thing.

i hate when that happens...

glad to help

ya that was frustrating lol. nowhere in the manual does it say anything about it lol. but it sounds good now, atleast to me it does, next time im out and about ill see if i can get one of you guys to help me tune it properly tho lol.
