CB Converter Install Questions

[DonQuiXJote]

Hi all, I just wanted to get some extra eyes on something because I'm a functional know-nothing when it comes to electricity. I picked up this Sparkomatic CB-10 AM to CB converter at a secondhand store and it seemed pretty plug and play; on/off switch a sensitivity knob that I assume controls something like squelch. You hook it up between the antenna connectors by the passenger fuse panel and run the red wire to power. So I did that, running the red wire to the leftover hot wire from when I swapped the passenger cigarette lighter for a USB socket (link to relevant thread - link to my very professional diagram of what I did). The wire coming out of the CB converter seems like it might be the next narrowest gauge from what I hooked it to behind the dash there, and I was wondering if that's going to be a potential issue, and if so, what I can do about it short of popping the converter open and trying to put in a new one. I'm more than happy to splice it in somewhere else too, but I'm not going to start digging around in the dash for wires until I have a little more of a direction.

Not really as dire as the above, but I was also wondering if anyone with more radio experience than me (ie more than goofing off with a handheld GMRS) has any advice on whether these converter things are even worth running and what might improve performance (other than the obvious, getting a real radio + antenna). There's a blurb in a Popular Mechanics article on these things that mentions they get a lot of static interference when the car's running, but I'm not sure if fixing that is within the realm of posibility.
