so i have a friend who has a infinity 1200 watt amp.. so she says.
its running a single 12; sub does this sound correct?

i was wondering if i could test my subs to see if their blown on this amp with out any problems..
im not sure what the rms is on her amp

 

she just told me it only has a single sub connection thing.

 

if your just looking to test them then it should do the job you can always test them one at a time you can hook them up to just about any amp to test them no matter what the power rating.

 

Most dual sub setups have a single wire running from the amp into the box, from their it splits into the 2 subs, at least that is a standard setup. More high end setups will frequently run the wiring in a more intricate fashion. As well you must work with whether or not you have dual voice coil subs, most people dont know that a dual voice coil sub must be connected twice to each sub. But again, all that can just be run from inside the box with a single set of audio cable from the amp.
