I'm a newbe and need some advice on an amp(s). I want to stick with my stock speakers for now. I plan on replacing the stock speakers and adding a sub down the road. I have 4X6's in the front and 6X9's in the rear. I want to be able to use the amp that I use for the stock speakers with the new speakers later. So I want to plan for the future. I can’t decide on 25 watt by 4-ch, 50 watt by 4-ch, two 2-channel amps, or a 5 channel. I’m wanting, in the future, 4X6’s rated around 50 watts RMS and the 6X9’s rated around a 100 watts RMS. I have small kids, so I only want 200 watts max going to the sub when I do get one. I’m not worried about band names just yet, I want to get the design down first.

I hope this makes sense!

Thanks in advance
