DC Audio has excellent customer support. I asked Thorshammer 3 questions in a PM. The first question was answered about 5 hours later, second response from him came about an hour after I posted my response, and the third response came about 20 minutes later..talk about FAST!!
I asked him, "would you put an XL or Level 5 on 2000 clean watts rms?" He surprisingly said, xl the lvl 5 really doesnt wake up till 4k or so ." This just shows that he is honest and doesnt JUST want your money.
I havent made a purchase with them yet, but im willing to when the time is right!
