[QUOTE="Franky, post: 8112644, member: 648067"] FML, I'm a *******... Not only is this my first big setup, but it's also my first ever multi-sub setup as well... I wired it parallel, so .5 ohms then; I guess it's a good thing that I have a good amp. And as far as the electrical goes, I have 2 XS Power D5100s in the back, a D1200 under the hood, Cadence 0 (power) and 8 (speaker) gauge wire, 2 positive runs to the back (currently only 1 hooked up because I'm waiting for some hobo on amazon to ship some more fuse holders), and I just got my Excessive Amperage 225 amp alternator in the mail this morning so hopefully I'll have that hooked up before the end of the week, along with the other 2 thirds of the big three. Currently with the 3 batteries, a stock alternator, and one run of 0 gauge to the back, it will drop to the 11's with the volume at 20 (which I've only done once). For normal listening it stays above 13 (or 12 if my friend is controlling the bass remote lol) Now that you guys have cleared up my stupidity... Should I leave it wired to .5 ohms? I bought the amp used, but I opened up the back just to take a peak, and it looks totally pristine and shiny. Also, my gain issue still has the same problem... yes I maxed out all of the head unit's bass / sub settings already, and lets just say that at .5 ohms the amp produces 4000 watts (just an example, please don't argue over sundown potential or box rise), that means that I'm still underneath the full voltage (which is about 50v) with the gain maxed out. So what should I do about that? [/QUOTE]
