The RCI 63FFC4 is a monster with it's big built in amp for sure. We get many calls about this radio vs the Connex 4300-300. Which should I get as often asked. Well the answer lies within, but we'll try to help you out a bit. Dollar for dollar the 4300-300 is prob a better built unit. You get more bang for the buck with the Connex. Connex builds simple looking, but very well built radios. However if your looking for big talk power, with alot of show check out the 63FFC4. All chrome, with a digital freq counter, echo/reverb and 10kz its got what your looking for. Var rf power is a must as well and it comes with it. So what issues should you think about? Well first price......monster SuperWackPacked radios cost some a week at work just to pay for it! Second its only am/fm, and so is the 4300-300 Connex. If your looking for max show this is the way to go. If your looking for brute force then the vote goes to the Connex. RCI 69FFC2 am/fm/ssb chassis maybe the way to go now if your looking for this radio with ssb however!
