So, the 150 would be worth a rebuild?? And the salesman wasn't lying when he stated that it could push out close to 1,000 watts. I am starting to get back in to systems again. The amp would be pushing 2 Volcano CDS they are 400 watts RMs 800 watts Max. This will only be a temporary system until I upgrade. I am contemplating on going with 2 or 3 Napalms. I have been corresponding with the manufactures of my old volcanos (which they do not manufacture anymore). He told me of a few new lines they are coming out with. The Napalms he said are 1000 watts RMS. He is supposed to be sending me the specs on them. The system will be going in a 2000 Honda Civic. Thanks for the help.
