okay this is my first real setup for my speakers. out of everything audio i know less about speakers then anything. i believe the pbxs sound very nice. i dont know what to compare them with because i havent heard very good sets. ive heard the boston Zs, but they are out of my pricerange. i got the 6x9s and the 4s. i havent got them hooked up yet but they will be running off a orion 225 hcca. they are 4ohms around so that will give me a 1 ohm load at the amp if i am correct. i know i will be underpowering them, but do you guys think it is underpowering too much? im not sure if you guys have even heard of these speakers. just let me know what you think and some advice please
