I just wrote out a massive post and I don't think it posted.. so I'm going to be fairly breif now.
I have 2 Infinity 6x9s on my parcel shelf and I'd like to wire them up to an amp to get their full 100w RMS potential as they're currently getting around 23w from my headunit.
I've been recommended a Vibe Blackbox 1 by a mate from work, but am confused about the 2x70w RMS output at 4 Ohms and the 2x100w RMS output at 2Ohms. Basically what I want to know is if I get this amp can I get the most from my speakers.. if not what would you recommend?
Cheers!

the 2 ohms part means that if the two speakers are run in parallel from one channel, you can get 100W RMS per channel. However, this would only work if you are running 4 speakers from it (2 from eacdh channel).
Basically, for the application you are using, you will run one speaker from each channel, meaning the impedance of the load on each channel is 4 Ohms.
To sum up:
You will be running the amp at 2x70W RMS for the set up to be correct.

The other option you have, which I am using, is the JBL 75.2.
It runs at 97W RMS per channel with one speaker per channel, which is the layout you would use.
I'm using it with my Infinity components, and have no problems at all.
They can be picked up pretty cheap on eBay as well brand new, I got mine a year ago now for £75 delivered.
Hope I helped Dom

The BB1 is old and outdated now.
The following amps would be fine for you:

Cheers, at the moment I have a mates BB1 linked up to my 6x9s for the time being. It's not mine though, so I still need to buy an amp of my own. But, I now want to get a decent sub too. Will I need an amp for the sub and an amp for the 6x9s, or can I get one to do both?
What are people recommendations?
I was thinking something like:
