I had my four channel running (don't laugh) a pair of motorola horns , 4 pioneer 3 way 6.5's on the front and on the rear was 4 mid 90's infinity ref 6.5's , a pair of MTX mids and tweets out of the full range truck boxes. The 2 channel was running 2 crossfire db 15's and 4 8ohm mtx terminator 10's. And this **** wanged hard as hell considering it was only about 1100 watts total. I was the loudest mofo in my neighborhood. All that in a '83 regal , on a blaupunkt deck with one set of 1volt pre-outs. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif had the matching profile 2 way x-over too.
