i have the same question between 300.4 jl and pdx 4.100 better sq and louder?
Your statement lacks the meaning of asking a credible question. An amp is only going to amplify and dish away with what you don't need to hear, such as road noise. Be more concerned with the drivers ability. Also, the PDX does 100 X 4 and the JL does 75 X 4 (All @ 4 ohms). Match up the rms with your driver and decide from there which one would suit your needs best.
