2 2500s or 1 5k - Pros/Cons ??

Example...

System is 2 d2 subs on a 2000 watt RMS amp wired at .5. That amp is seeing a half ohm load to begin with. 

System 2. Same subs (d2 x2) but this time you have 2 x 1k amps and they're wired to the same .5 impedance. Each amp "shares" that load to make .25 at each amp hence the term "splitting rise". Same ohm load but 2 amps sharing that load now ( naughty lil amps haha). It makes sense to me. Impedance rises to 2 ohms with a single amp and that 1 amps sees that total rise... Slap 2 amps on there and the rise may be different, because power and resonant frequency play roles, but whatever impedance your system rises to, one thing fasho is when there's 2 amps they share that rise.

ih What does that have to do with rise  other then you start with a lower ohm load the rise in the same box will still be the same

And the two amps will share that "same rise"

Lost,.. how adding more boards, power being equal,  does anything different with impedance. :shrugs: 

Doesn't do anything with the impedance. I was saying that whatever impedance it rises to, having multiple amps share the rise. I said "could've sworn" meaning iirc I read this somewhere. I'm still learning so I'm not making claims I'm kinda asking for clarification. Don't want anyone thinking I'm stating facts. Iirc multiple amps split rise I read on this site somewhere. Idk? I just beef up electrical and wire down a little. Not into the sedimentary rock like .25 or .33 for daily but definitely .67 or .5
