Ever consider that maybe I had a different amp on the 15w3's than I do on my 4 10's??? Every consider on clicking on my link to answer your own question before you start saying my system is weak??? 146 in a s10 blazer off a 81000D is pretty dam good if you ask me,...without any mods done to the electrical system. No caps, and so on. You seem to like 1000's of watts on subs to your liking....but to mine it's totally different....yet to call someone elses system barely doing 1000 watts is weak. Perhaps your one of those hardcore SPL fans who can afford a 2000 watt amp every week and throw a type r sub on it and hit 150 all day long. But to have you sit there and call my system weak when I poured my hard earned money into it is just plain weak.....and an idiot for doing so. So what if the type r is better....I think I have my say as far as the se10 is concerned, don't I????
