Yea i heard Clarion did that. I also have the head unit mac made too. When you hooked up the headunit to the amp it had a anti clipping device in it that would not allow you to blow the subs. Problem was some people hated the look of it. Down at my parents in a box i still have a 6 channel blade amp, a 4 channel butler tube amp. a couple audison products, some third octave EQ, and some speakers and amps most have never heard of. I have a monolithic (super hi-end and the only true class A ive ever seen) it draws 25 amps at idle but sound is unmatched. Ive also got a component set converted from hi-end home speakers. Its scanspeak 8 inch mids with 3.5 inch dynaaudio silk dome tweeters. I tried the image dynamic horns when everyone loved them and i wasnt a fan.
If you remeber some of the big names bitd like richard clark, i sat in his grand national..the one that supposedly the shiz and i wasnt impressed at all. Very bright. I like a high range a bit mellower thats why i ran the silks. Good luck on you search I honestly have not kept up with the modern stuff. As long as my old stuff plays and sounds good im not messing with it.
