This is straight off the website I have hooked up quite a bit of their ML series which is a step down from these and those really have some punch to them with only 370x2 RMS do you have any recomendations on how much power you would put to them they are dual 1 ohm voice coils so I can wire the voice coils in series and the speakers in parallel to put a 1 ohm load on a class D amp.  But I am sure you are alot more experienced than I and am looking for any insite on my project.  thanks again for all the help..

Has anyone used or heard the SPLW series? If so give me a little input..
