Can you're 6.5's play all frequencies?? Absolutely no they can't. That's why you set your amp to HPF and set the freq's. I'd start at 80 and move up if need be. Setting the amp on HPF and setting your crossover frequency cuts out any signal lower than where you have it set. Example...with it set at 80 it cuts out all the lower freq's that your speaker cannot play below 80hz.

U could start at 45 in a car or truck. But in the sled environment u have to get far more aggressive with watts thus the higher HP freq. The high watts will crater a 6.5 when u open up the filter to play the low freqs.
Give it a shot but be conservative. U will hear them take a knee (distort) pretty early in the game as the volume increases.
