Question here ,

I Run 2 type R 12's the 2 ohm ones , I'm wanting to run 3 in a ported box, so I call up my dealer and get the hook up for another sub, subs are powere by a PDX 1000.1 this amp runs same RMS @ 2 or 4 ohms , ok so I get ready to pick up my sub and he calls me back and sez I gota swap out my 2 - 2 ohm subs and get the 4 ohm ones to have them run off my PDX is this true? 3 cant run together??, he sugesed that I just buy another 600.1 pdx to run the 3rd sub, ?? that sounds ghetto to me or is that common.

need feedback on this one this could cost me to pick up another pdx. thnx in a dvance

1 amp, 3 subs, dont use 3 subs and 2 odd amps

But in all seriousness, what I would do would be to get two 4-ohms and one 2 ohm, wire the two subs in a parallel configuration for a 1 ohm load, wire the 2 ohm sub to a 1 ohm load, then treat the 4-ohm subs as an independent system, and wire the two subs to the other via series-parallel for a 1 ohm load across the board.

i was going to say that . they taught us that in school series parallel

Draw this out.... Doesn't seem right.

Either way the PDX doesn't run at 1 ohm

Oh shit, just kidding OP, I didn't realize that you're getting 1kw at 2 ohms from that amp. If you want to keep it like that, then just pick up a 4 ohm sub, wire your current ones in series parallel, wire the 4 ohm sub in parallel, then wire the two subs to the new one in series parallel.

Two dual 4 ohm subs = 16 ohms series, 4 ohms S/P, 1 ohm Pdual 2 ohm sub = 4 ohms series, 1 ohm parallel

I am assuming that if you treat the two sub system as a single DVC sub, you could wire it in S/P to the single sub in series parallel. I'd have to try it, but I don't see an error in the theory. Correct me if I'm wrong though. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Take that back, ultimate is right. If you do it the way that I did, you cannot rely on doubling the resistance of a speaker then wiring it to another one in parallel, as you've already done that. You would instead end up with a net 2 ohm or .5 ohm load if you did it the first way, which I believe is what you wanted initially anyway.

Didn't you read the thread title though? //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
