Would this amp power nicely the SQ10 if wire at 360x1 @4ohms bridge? (can it be wire like that)

not sure if the SQ10 (mine is the SVC) rates at 250rms or 350rms
and its late and i'm not thing straight for now :eyes:

also, an amp like this should also power up some nice components rite wiring them at 4ohms 90x2

It'll be fine if your SQ10 is 4-Ohm SVC, provided you have the gain set correctly, to ensure you don't push the sub beyond it's limits. Yes, it could instead be used to drive a 4-Ohm component set (again, the gain should be set appropriately), 90w is fine for most when hi-pass filtering is used.

I think the SQ-10 is rated 300Wrms max. It might be able to handle more... but that's not what it's designed for. Stick to 250-300W max.

An amp that produces more power than a speaker is rated for is safe to use, provided the system's gain is set appropriately.
