Ok i have 2 - 12" DVC Cerwin Vega Stroker subwoofers rated 2000w RMS & 4000w Max...... and right now powering these subs i have 2 pheonix gold Octane-r 1500w mono amplifiers.. one powering 1 sub and the other powering the other sub!!

I just don't feel as though the subs are getting enough power compared to what they can handle!!!  so i was actually thinkin about buying 2 more of the Pheonix Gold Octane-r 1500w mono amps..(exact same as the ones i have now) so that i could run (having a total of 4 identical amps now) 2 amps to each subwoofer by connecting 1 amp to each voice coil on the subs!!

i believe doing so would be safe as long as the amps are all at the same frequency and all!! but i just wanna check and see if i am able to do this without damaging the subs or amps!!

So can i connect 2 amps to 1 DVC sub by connecting 1 amp to each voice coil??? 

the amps are pheonix gold which have a config switch so only the master amp controls settings and each additional amp controls are bypassed so they all run exactly the same!!!

Yes you could do that.  I don't know if your subs will handle the power, but technically there is nothing wrong with doing that.

Ok thats what i thought!!!

I just wanted to check and see if it was ok because even though i was almost positive it was ok... i figured id rather be safe then sorry!! lol

and i think the cerwin vega's should be able to handle it with a 2000w RMS & 4000w Max rating for each sub!!!  and of course i wouldnt push em harder then they should be!!!

So i think i am going to get me 2 more of these amps and do that!!

my stereo pounds so damn hard now... about 130db actually!!! and thats not even giving each sub the power they need!!!

what impedance woofers are they, and what impedance do the amps make thier peak power at?    If you add 2 more amps but are running them all at twice the impedance they were running before you will see no gain

damn it.... thats right i totally forgot about that part of it!!

so it would be pointless to do that then cause my amps are 2 ohm stable and the subwoofers are 4 ohm DVC!!

When i bought the subs i got the 4 ohm DVCs because i was only intending on having one amp to each sub.... thus wiring the subs in parrallel config. to get 2 ohm load to the amp!!

but i can always still return the subs and exchange them for the 2 ohm DVC subs which are the exact same as the 4 ohm DVCs only with 2 ohm DVCs instead!!!   so there may be hope for me yet with doing what i would like to!!!!

thanks for mentioning that.... i totally forgot about that!!!   so thanks for reminding me!!!

Huh? That makes no sense... "giver"?
Additionally, they can be completely different amplifiers, or even one turned off, or one all the way up and the other all the way down, or even one out of phase and cranked, and it won't hurt anything at all...
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."

Are you saying he can wire one coil of his dual voice coil woofer out of phase with the other coil and it will not hurt anything?
