oh...and the speakers hiss. it happens when the amp is both plugged into and unplugged from the avr.

ok guys. here's where i'm at... i tested the setup by wiring the speakers up to the amp directly in case my terminals were somehow jacked up. no difference. i double-checked the speakon connections and changed one of them to +2/-2. no difference. i tested different rca cables, including the one i currently use on my existing sub. no difference. i tried various settings other than stereo. no difference. i plugged my old hsu 12" sub in and turned it up and tested the same song through the receiver vs the 2 18"s at full volume and the 12" was massively louder. the only time i really got them pounding was when the avr volume was really high. even then, it was less than overwhelming. could it be the amp? kinda pissed. the only thing loud about the amp is the fan...which is ridiculously loud. are there other options in the $300 range? should i send this one back and get a different one?

Thanks. Starting to panic a little since I don't really have the time or knowledge to figure all of this out. I appreciate the help you guys have provided. I guess I'll try a couple different configurations after class tonight and then tomorrow. Not sure how I'll be able to tell if the amp is bad or not. BTW, someone above mentioned that it could be sending all the signal to the sub and that I couldn't tell. I really don't think that's it because with the sub volume on the AVR all the way up and both channels on the amp all the way up it was still barely audible.

Also, what is the correct ohm load to set? I've got 2 dual 4 ohm drivers. What does that add up to?

A couple of things. First, I thought you only use +2, -2 if you are running a 4 pole connections from a single amp output to two different speakers. I was under the impression that if you ran 2 lines from separate amp outputs they would both use +1, -1. At any rate, I'm happy to try running it with +2, -2 but I'm a bit skeptical since both channels are currently very quiet. Second, if I run bridge mode, that means another set of holes in the wall going from one sub to the other. If rather avoid that if I can.

from everything i've read, the speakon connection is just red into +1 and black into -1. i have the 4 pole version. don't think even i can screw that up. http://www.amazon.com/gp/product/B005EKMGO4/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

FWIW, I can try any combination of settings and wiring right now as the subs are next to each other and the amp so that might help with seeing what the issue is.

this is frustrating. i'm mainly choosing stereo because i don't want to have to run a speaker wire between the two subs. doesn't bridge mode require that? i'm not worried about the configuration that will give me the very most power since i won't be running them super high. i'm just trying to get my two output from the avr to make sound. i thought stereo was the best option since i have a 2 channel amp.

did you do like I said and try witching the subwoofer mode to LFE+mains? i'm at work so i can't do it now. but IIRC, i had it like that for a while last night before switching it.

so....dual mono or bridge? and any idea on why both channels are super quiet?

this is how i have the drivers wired

Denon settings

behringer inuke options

got it all hooked up. not in the right spots and i'm waiting for longer screws to mount the drivers but good enough to hook them up.... .....and i can't get the volume any higher than to where i can barely hear them with the gain turned all the way up on both channels. i have it set to stereo. my connections rca out via xlr adapter to the amp speakon connectors with the12g speaker wires hooked to +1 and -1. speaker wire to the speaker connector. red from speaker connector to the + on one of the coils. red jumper to the other + on the other coil. same with the black. am i missing something? does my denon x4000 have some sort of limiter or what? i can't find anything on the behringer app that's limiting it. the subwoofer volume is set at 0 like the rest of the speakers. aaarrrgghhhh!

that's great! i'll have to remember that.

Hey...quick question. What kind of treatment should I put inside? Do I need to get some accoustic egg foam? If so, where can I buy it? Should have thought of this before tonight!
