Arc Audio 5150XXK question

[MajorDzaster]

I've decided on a Soundsplinter RL-i8 sub for my new system, but I am unsure if a 5150XXK is sufficient power for this sub. It is rated at 190Wx1 @2ohm, according to their web site, but it is unclear as to what the power output is at 4ohm. I placed an order for a SVC 4ohm sub, and I am thinking that I may need to change it to a DVC 4ohm if this amp can't put out enough power at 4ohm. I am also considering the DLS A5, but I would rather have the flexibility of a 5 channel amp over a 3 channel amp.

What is the 4ohm sub channel output for the 5150XXK? Is it enough power for the RL-i8 (at either 2 or 4ohm)? Is the A5 a better choice?

if i recall reading correctly it'll do 150 @ 4 ohms. most of the time arc amps are a bit underrated so expect i dunno 10-20 more watts but that doesn't really help.

if you want more power than the A5 would be a better choice.
