Adjustable sensitivity range:0.1V-1V
Input impedance:Low level(10K ohms), High level(100 ohms)
Dimension(WxHxL)mm:262x59x429

Would somebody please let me know which amp i should get? And also i understand that if i wire them in series/parallel i will be running 2.6 something Ohms and both amps can handle that. But i dont know how to wire them, should i just bridge the amp into one channel and then run the subs in series/parallel and if i do that, which amp will i be able to run to get the most power out of the subs but not too much? Or should i wire them differently or perhaps just buy a single channel amp?

neither one.
you need a mono (one channel) amplifier that's 2 ohm stable, for three of those subs.
you'll need to wire the coils in series to get three 8 ohm subs, then wire all 3 subs in parallel to get a 2.6666 ohm load.
only way to run that configuration.
can't do it with a bridged two channel amp that's only stable to 4 ohms bridged.


wow, this post number is in binary.. haha
