two subs, two amps?

i have been wondering if channel separation of a sub would work , by this i mean having two amps , two subs one wired to each amp but only using one of the two rca cables per side , I think it would work ,and if you are asking why i would want to do this , its because i would think with the music i listen to (heavy super fast kick drums metal) it would not only separate the channels but in turn run the subs more efficiently hence cleaner more responsive bass .

thanks

Are they identical woofers?  Are the amplifiers identical as well?   Tell us about the woofers, and the amplifiers.  Single voice coil, dual voice coil, the impedance of the coils.  What is the minimum safe operating impedance of the amplifiers. 

yes two matched spl 12 inch dual voice coils , with matched spl 400d amps 1 ohm stable , now i should mention im running one of each right now with the other woofer and amp still in the box and im running it at 1 ohm , so my thought was why not run two separates with channel channel separation, as i stated one rca to each amp ??? my thinking into this was if you pull one rca off your sub amp you lose bass ie one channel , i just dont know if im correct
thanks for posting

Your amplifiers are one channel amplifiers.  You may need to feed signal to both RCA input jacks of each amplifier. 

What you are wanting to do is done daily.  It will work just fine.

thats what i wanted to try though only one rca per amp

i should add these woofers are in separate boxes

Left RCA to one amp and right RCA to the other amp.  However, depending on the amp, you may have to use Y adapters to feed both inputs of each amp.

kool thanks for the replies

And you're worried about "clean bass"...

Jim... That aside, there is no stereo information that will be discernable below 80Hz in the car - it's physics. If you don't already have the gear, but are considering the purchase of MORE gear to achieve this result, you'll gain nothing with the additional outlay of cash.

If "audiophile" bass is what you're after, you are going the wrong way, amigo...

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

ill give you a hint. as a fellow lover of all that is metal, the two things that matter most is a good mid and the discipline to keep your sub turned down and let the mid do the work from about 120Hz and up. if you let the sub have too much bandwidth then it just doesnt sound as "quick" as it needs to be to keep up with rapid double bass drum, not to mention trying to play accurate notes from a bass guitar with distortion applied. its just too must for a sub to handle by itself.

it might take a little bit of playing around with gain and crossover settings to find a sweet spot for your particular equipment but it does exist.

if you do this til the sound is clear and "quick" but you find you dont have enough volume or punch, then you should think about spending your money on better equipment instead of more equipment.

my bass is very clean , if you are questioning the gear ?. there is no problem there it is very clean aside from what i posted im running morel mt 37 tweeters with cdt blending tweeters and re audi0 xxx 2 ohm mids and an
ma audio 1700xe amp for the mids , i can tune a stereo im 40 and have been doing this for a while my gear at home is all high end 20k plus worth , and as far as tuning ,my system sounds great , my question was concerning channel separation of subs l/r."audiophile" i have

thanks for all of the replies and comments

thanks man , im running my mids at 125 and as i stated they are re audio xxx and morel mt 37 tweets they really work well blending with the sub and the sub gear im using is great the kicks pound through your chest and the amp never gets hot , panteras uplift literally was bouncing change out of my door rull

thanks
jim

man you have a very random assortment of components, what are you using for a crossover on all those speakers?

ok so your mids are crossed over at 125Hz, at what frequency is your sub crossed over? if you have it set too close to your mids xover point then depending on the slope you could have too much of an overlay. so it makes your sub and your mid try to play the same frequencies right around where you say you are having problems. having different speakers playing the same notes can make it sound muddy or slow or just generally not right. so you may need to lower the subs xover point to about 80Hz

again this is only my opinion based on experience. im not one of these brilliant mathematicians on this site that can explain everything with numbers and values.
