[QUOTE="dafobbishon3, post: 8335449, member: 605002"] Oh okay I get it, I see why they put those two extra terminals in my amp. Well I instead of daisy chaining, I just put the wires in each of their own terminal respectively just because it's neater and less of a hassle. And I try to set my gains and to see if my subwoofers work, and they don't! I know what to set my gains to. Voltage goes from 9V-0.2V And my preout voltage on my Head Unit is 4V so I wanted to put it around there, or even higher at 7V just so I can break my subwoofers in. Subsonic is around 25hz. LPF is around 80hz. Bass Boost is at 0. [IMG]//content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif[/IMG] I don't know what's wrong. I tried to turn on the gain a little bit, then a lot a bit, and nothing was coming out of my subwoofers. The amplifier is clearly on, it doesn't go into protect, the green power light is on. Everything is connected. I try to mess with the Bass EQ even just to hear any thump, and still nothing! I even try to mess with the EQ on my Head Unit and nothing! There is no output whatsoever on my subwoofers! This is extremely frustrating, it already took me three to four hours to install everything, mount it on the back of the backseats and everything and to have the subwoofers not work... I honestly don't know what went wrong. I built my old setup from scratch, and built it and put it together all by myself no problems. My old 15' was a DVC@2ohms.

I tuned it perfectly, I've had that setup for at least 3-4 years no problem ever arose. I know what I'm doing. I tried to take some pictures, it's really late and my phone doesn't take good pictures in low light. Any ideas as to why it's not receiving any output? [IMG]http://i59.tinypic.com/21nqdyo.jpg[/IMG] This is the side where all the knobs are, and there are two sets of RCA outputs, I put it on the left set because on the Hifonics manual that is where the "designated mono line input" is. [IMG]http://i59.tinypic.com/20gij5k.jpg[/IMG] This is the back of my enclosure. At the back I wired them just straight to 4 ohms. I even checked with my DMM. It sits at exactly 3.8 more or less from the back of that terminal. [IMG]http://i58.tinypic.com/29mlgk9.jpg[/IMG] This is how I wired it to the amplifier. Since the terminals look like this - - + + I wired the subwoofers accordingly like this (first sub wires will be P1 and second sub will be P2) P2- P1- P2+ P1+ Should I try to daisy chain it into one set of terminals instead? I mean even if I do that, I don't think it should solve problem because right now how I have it, whether it is at 4 ohms or 2 ohms, I should still be getting output of my amplifier to my subwoofers, but I hear nothing and I feel nothing coming out. :\ I tested the amplifier with my DMM and I tested the power terminals (not the speaker terminals) and I got a 14V with the car on so that's good. Amplifier is working. There's just gotta be one small thing missing. But I don't know what! Please anyone help! I'd rather try and fix it myself before I turn it in to an audio shop and ask them to diagnose it. If it helps, here's the setup HU: Pioneer Premier DEH-600UB Subwoofers: 2 12" Kenwood KFC-W3013PS Amplifier: Hifonics Brutus BRX1100.1D Rear Battery: Kinetic HC600 [/QUOTE]
