wiring 2ohms and 4ohms sub together

[ikoolguy 10+ year member]

the title pretty much sums it up

i have jl 500/1 amp and 2 subs one sub is 2ohms and the other is 4ohms. a friend told me i can wire it into 3ohms.

well i did a little research online and said it will do some damage

should i be worry about my amp and my car?

or will it be okay to run the subs at 3ohms?

your friend is dumb. don't do it. use one or the other, not both.

what subs do you have?

if the power handling permits, i'd just use the 2ohm sub by itself and let it get a full 500wrms

I know most of the time you can't do this, but I those JL amps I believe are good for 500 watts for 1,2,3, or 4 ohms. I think you're alright.

Why not? I mean...if the end load is 3 ohms, each sub would be getting the power.

Wire the DVD 4 ohm to 2 ohms, then wire the DVC 2 ohm into 4 ohms. Then parallel the subs together to get 3 ohms. Is this possible?

aren't the d3 dual 2ohms? and rated for 400wrms?

just rock the d3 man!

one d3 is 2ohms and the other d3 is 4ohms

i got it wired to 3ohms

is it safe?

if one has less resistance than the other, will they both receive the same power?

4ohm plus 2 ohm is not 3 ohm its 2.66 also the 2 ohm sub will get more power then the 4 ohm so its not a good idea

one d3 is 2ohms and the other d3 is 4ohmsi got it wired to 3ohms

is it safe?

are you the said 'friend'?

so the dvc 4 is parallel for 2, the dvc 2 is parallel for 1, subs are in series for 3??

That should work fine. One sub moving less than the other isn't going to have any real effect on sq.
