The Q is 1000w RMS with no options. sorry, but i meant 2 stock Q subs. if i can do an inexpensive electical upgrade without getting out of hand i could see myself doing 2. i think my stock alt is 120 amp..i currently have around 900 rms watts with 3 old school 2 channell punch amps and about 4 gauge wire. it is too little as is wit that setup so i know i'll need to upgrade to make it happen

The Q is 1000w RMS with no options. i'm doin 2 subs..

thx guys .i was gonna put 800 rms on each sub. was thkinking between 2.5 - 3 cubes per sealed. trying to hit that sweet spot of 25-30 hz without totally sacrificing 40-50 hz.. I'll do a little more research. Sounds like this may not work with that much power in that size box. i was gonna be using standard coils. anybody wanna take a guess on whether or not i should ditch that particular sub for sealed? sounds like a guessing game in terms of output. I guess a stock Q would work however i didnt really wanna do a 2000 watt setup.

thx for a quick reply. i'm thinking 2.5-3 cubes per sub..trying to figure out if i'd benifit by giving my enclosure more breathing room thus me going 2.5 cubers per.

on the fi site under 15 they dont give a sealed box size. do these subs worked in sealed enclosures? i'd like to get a FI rep to give a recomended box size

i figured it out. i should have around 3.8 cubes per chamber when all is said and done for either a pair of SSD, Q, RE SE or L7 15's. decisions decisions

thx a lot for the advice. i'm going to be running 2 of them so they 'll get around 600-750 each rms. My box that i'm gonna build is gonna be around 4 cubes per chamber before i calculate the speaker displacement which i dont totally understand how to calculate that part. not yet anyway.

actually i do prefer the music that dips below 25 HZ. And i'm just being stubborn about sealed. I know it may be dumb but im gonna use a sealed box regardless. and even yourself pointed out that a sealed would be best for that frequency of music. it's just my personal preference of how i like to listen to my music man. Ever heard of the CD bass from the krypt? what about the SS series subs. would the output be that much difference than the FI Q? I love the price of the SS 15. thx for your reply man. I am leaning toward the Q's and starting with that 1500 rms. then upgrading to 2000-2500

I like for my lowest bass to be very strong. I'm not into the high/loud bass that you hear from street beaters. I'm very interested in the 2 Q 15's but since i have stock alt(2000 grand marquis) I doubt i go any higher than 1500 rms total for them. Which makes me think i'd waste them. Are the SS series subs as good with the low notes with that much power? I'm going sealed. I like the sound of subs in 4 cubes per and bigger. thx for any input..oh yeh, i also have the L7 on the list however my friends tell me the FI subs would destroy them
