Just like to clear up the tension and muddy water between everyone here.
I recieved DDbump(Jakes) 2 15"s to test and get numbers. I put them in my brothers Eclipse on a Earthquake PH2000 at 2ohm. Amp does just under 700wrms at 2ohm. So something like 350wrms to each sub. On my TL i did a 147. I will look for the screen shot as I usually save them. Then we placed the 2 15"s in Jakes wall and wired them to .5ohms on a DD Z1a and it popped a 152. Obviously it wont do that all day on music but everyone who has used them or heard them has said they are loud and sound great doing it.
I think Mike (MLstrass) is a good example because he is unbiased. If anything I expected to hear him say the HDC3s will do better cause I know he loves the response he gets from his. The subs put up as promised.
No one has said any different. Everyone is happy with them and run them to their fullest. People are just upgrading to bigger sizes or in Terra's case he is actually down sizing to several 15s instead of his pair of 18s.
BTW sick build and sub/amp combo Andrizzle. Sorry your thread is getting shitted on.
