I know this may be a dumb question..but i believe a dumb question is one that was never asked!! so if someone would clear this up for me i'd appreciate it!

ok my buddy just sold me his 15" fi Q dvc 1ohm...

i already have a kicker cvx dvc 4ohm

now i am gonna buy another fi Q but money is an issue right now and i need some knock right now

so the question is if i wire the fi q down to 2ohms and wire the cvx to 2ohms will it be a 1ohm load or not? and why? i know they are different voice coils but 2 subs dropped to 2ohms=1ohm

and my amp is 1ohm stable, would this work or will it fry my amp?

Don't run them both on the same amp...

i drew up a little circuit to look at this set up, and both subs should/would see the same current, if i remember my circuits class right. but each coil would see different current. one 1 ohm coil will recieve X amount of amps, the second 1 ohm coil will recieve X amount of amps, one 4 ohm coil will recieve X/2 amount of amps, and the second coil will recieve X/2 amout of amps. When wiring the Q in series and the crx in parallel, the Q will see X amps and the crx will see X amps

X is the same through the whole explination.

edit: its still not reccomended to have two different type of subs in at the same time for sound quality reasons. Just stick with one sub till you get the second Q

^^ There is much more than just current that plays into that.

Just don't do it. Simple as that. Don't do it.

How long have you been into audio?

Voltage remains the same to each sub, but acts different on each coil.

each sub gets Y amount of volts. the Q's 1 ohm coils each receive Y/2 volts and the crx's 4 ohm coils each see Y volts

so Watts = volts * amps

Q: one 1 ohm coil sees Y/2 volts * X amps = (X*Y)/2 watts

CRX: one 4 ohm coil sees Y volts * X/2 amps = (X*Y)/2 watts

but now thinkin how does Power (Watts) divide in parallel vs series?

How about different T/S parameters? Box requirements? Port requirements?

You can't do it.

Oh. i added that in an edit to my orginal post about in not being reccomended to mix different subwoofers,

but i was more goin into the electronics part proving each woofer would stiff recieve equal power and not fry the amp

Ok you CAN do it, but you shouldn't..... at all..... ever.

I know you were, someone needed to tell him the whole story though. Thanks for the edit.

I still think if people have to ask this, they shouldn't own expensive equipment.

this sentence is the first quote for my signature..hah

SHAWWEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEET

You can't do it.

But people mix high's with different impedences and different speakers all together all the time and run them. You can do it and I've seen it done several times. I've seen spl competitors run mismatched subs and their scores go up because of it. I've done it in my car at one point. I ran a dual 1 ohm Nightshade at 2 ohms and a dual 4 ohm Type R at 2 ohms and then ran them in parallel to my amp at 1 ohm. My score dropped off from a 148.1 with 2 NS to a 147.6 with 1 NS and 1 Type R. Now the Type R isn't even in the same class as the NS, but my point is that it worked fine and I didn't have any issues running it like that for 2 weeks or so until I got a recone on my other Nightshade. Jacob saw it when I went to Sundown to get the sub reconed.

Using different speakers for highs is easier. they are not in the same enclosures and are ususally crossedover at different frequencies.

As for spl numbers you can get higher numbers from addin more of different types of woofers. more cone area usually leads to higher numbers, but the box used wont be perfect for each woofer. and electrically it will work. also if one woofer has more force that the other it could probably damage the less powerfull woofer, if its a common chamber

I can't get over my quote in that sig!! It's awesome lol

hah i like it.

I hope this thread is dead. So we are not thread jacking to bad lol
