Since Loudsystem hates all my ideas, I'll just put this out there for anyone to answer. I am looking for new subs and amp to get in the next several months. Here's what I like so far: Hifonics Gen XI Hercules (1500x1 @ 1 ohm) -This amp is extremely efficient, and only requires an 80 amp fuse. With this amp, I won't have to upgrade my alternator. Does anyone know anything about this amp. Is it a good choice? Is it underrated at all? Subs I'm still undecided on. I could do a single DD9515, which I think would own in a nice blend of SQ and SPL in a medium to large sealed box. I could do some Adire Shivas, or a single Adire Brahma. I could do a pair of IDQs perhaps. I'm open for suggestions on the subject, so give me some opinions. AND NO JL!
