 Is this amp enough + Sub out Question

Hi Guys I posted this on another forum but figure this is a better place to put it :) I recently bought a new sub and amp combo off the net. The sub is a Sony 12" 1000W boxed sub (that's all the info I can find on it) and the amp is an XM-SD12X. I've read everywhere that sony are pretty poor in car audio equipment, but I really couldn't afford anything else and I heard one of these (friend has one) and it wasn't that bad. I bought the combo as I figured the person has been running this combo for a while, which of course I assume means they should be good for each other (as the amp model number was not listed). Anyway after finding out the amp model number and doing some research on the net about matched sets and stuff, it looks like this amp should only be powering speakers and not a sub! Would I be correct in assuming this? I found specifications and the manual on the Sony website. Link: www.sony.co.uk/support/en/product/XM-SD12X/specifications I don't intend on running the sub at 100% or anywhere near that if it makes a difference. I've only got it to just add a bit of bass to my music. I plan on running it in "bridged mode" (i think? Where you hook the +'ve to the amp +'ve on one channel and the -'ve to the amp -'ve on the other channel?) so I can use the whole wattage on just the sub. Also, just another quick question....my head unit has both Sub out (single RCA) as well as multiple RCA outs (red and white). The cable kit I have is a dual RCA to dual RCA. Would it be worth getting a Single RCA to Dual RCA (or an adapter for my current RCA cable) to be able to hook it into "sub out", or would this make no difference? Thanks in advance!!!!!

It will work. That's a very low power amp though. The sub is probably around 300w rms and that amp is only going to get it ~120.

The cable situation isn't a big deal. If you don't have a mono cable just use one channel of your standard 2 channel cable. However, I would suggest picking up a 1f/2m y cable to connect the mono cable to the amp's stereo inputs.
