the correct advice
64met,
You seem to be getting some bad advice.
I am not sure what Outlaw sub you have but let's assume it is the LFM-1 EX. The rating of that is 350WRMS; 1300W peak
You said you are looking for surge protection as well as power conditioning. The APC H-15 was on sale for $149 and can handle 1500 kva which would easily handle the peak as well as the RMS power.
you could have other devices on a power conditioner as long as you correctly add up your total KVA requirements. However a LFM-1Ex Outlaw sub might be all you want on a power conditioner.
However, if you are just looking for surge protection ,then the cost would be significantly less. To be fully protected from a large electrical storm power hit or a brown out surge look for one that is rated at 5000 Joules or higher. However, if you hacve power fluctuation then you would need the voltage regulation in addtion to surge protection.
Good Luck!
