[QUOTE="tangmonster, post: 135576, member: 1581"] Where will the low level signal come from for these two subs? no issue with putting 2 x 12" in a sealed enclosure, just double up on the volume that you would use for one. my limited experimenting with winisd and the jbl gt5 showed 250L for two subs , but i am going to use 160l with very very little difference in responce. Since they are 4 ohms , you will need 2 amplifiers fed from a single low pass filter for you woofers. the 2 woofers in parralel will have too low impedance. I know in Car audio world people frequently have 2 ohm loads but the math behind the current needs is insane and i would leave that to car audio world. not even talking about cable losses. anyhoo. IS this for music or movie use? [/QUOTE]
