they are 250w rms.....so you will need to use an amp to run them properly, my advice would be run them at a high pass x-over point 90hz, ish....they work well at this point...
sorry boss thats gone way over my head
just looking for a replacement set speakers at the mo that will work off the head unit alone, in the future will be looking for some top notch replacements.
anything a bit cheaper on the market i could use as a direct replacement for the standard items??????
