i just bought a audiobahn A8000T, its a 1 channel mono and it is 400x1 at 4 ohms and 800x1 at 2 ohms, i have 3 pioneer 12" TS-W306DVC's, i was wondering if this amp is a one ohm stable if anyone knows? and these subs are rated at 400w rms and 1000 peak..is this amp enough and what should i drop the subs down to (ohms wise), sum1 help im new to thisss! :)

Answer to question 1 is right there in the amp ratings.  What does it say the output is at 1 ohm?  If it says something, it's stable at 1 ohm.  If it doesn't mention 1 ohm, it's not stable at 1 ohm.  And post a link for those subs so everybody who wants to give you a hand doesn't have to search all over the web to find out something about them.  Or just tell us...DVC what? DVC 2 or DVC 4?  Reply back after you've done those things.

    I can't tell much about that amp but that it's got some goofy Audiobahn-type ratings.  Woofer Wiring.  It looks like your subs are DVC 4 ohm.

    yeah from what it looks like from me it says that the subs are 2 ohm or 4 ohm, and the amp dosent say anything about a 1 ohm it only says the specs at 2 ohm, so im thinking it isnt 1 ohm stable...wut would you recommend be the best wiriing for the 3,  series or paralell or what?

    Whatever is more than 2 ohms.  Did you even look at the link I bothered to post for you?

    yes i did, but im not sure what im suposed to put in for the drop down boxes, i dont know what would sound best and what not

    You put in what you have.  Three woofers, DVC 4 ohm if that's what you have.  The results you get are the choices, and you pick one that is 2 ohms or higher.

    well it says that single voice coil theyre 4 and dual voice coil theyre 2 or 8, so you think that amp can handle a 1.34 ohm load?

    Okay...now is the time you should sloowww down, read over what was already told to you, digest it.  Or do what I do when I start getting frantic;  go take a shhh and think about it.

    I don't know why you're determined to get a 1ohm load, but those subs and amp isn't a good match. First, you can't get 1ohm out of 3 4ohm dvc subs. Second, the amp doesn't say it's 1ohm stable. Only 2ohm and 4ohm. The only way to do the sub and amp combo is use 2 of the Pioneer subs, wire them to the amp in a 4ohm load. It'd be 400watts to the subs. You can't get a 2ohm load out of 2 4ohm dvc subs, so 4ohm is your only choice.

    I'd say get a bigger and better amp. Audiobahn is a bad choice.

    Wire the subs like this https://www.lightningaudio.com/latech/wiringwizard/2_4ohmDVC_4ohm.gif

    Here are your wiring options for the 3 subs

    Option 1 (series/parallel) = 2.67 ohm load
    Voice coils wired in series, speakers wired in parallel
    Recommended Amplifier: Stable at 2 or 1 ohm mono

    Option 2 (parallel/series) = 6 ohm load
    Voice coils wired in parallel, speakers wired in series
    Recommended Amplifier: Stable at 4, 2, or 1 ohm mono

    You should run them at the 2.67 ohm, 6 ohm would give you alot less power.  I doubt that audiobarn amp could handle 1ohm.  BTW i think wen pioneer give the DVC specs at 2 or 8 ohm they mean that each voice coil is 4ohm so the independancew load can be either 2 or 8ohm for each speaker

    i have an audiobahn a8000t, its a one channel 800x1 at 2 ohms, i have 3 pioneer ts-w306dvc's wired at 2 ohms, they are 400w rms and 1000w max dual voice coil, so im guessing the amp is at 2.6 ohms because i dont think the subs will drop down to 2 ohms, anyways i cant seem to get it to sound real good, can any1 tell me what i should do wit it, where i should have the lpf crossover turned at and should i have subsonic on/off, help please i need it to hit hard

    If those are dual 4's and you've got them series-paralleled, it's at 2.66 like you said.  Is the enclosure you're using designed for those subs?  If not, you'll want to remedy that first.  Start with around an 80 Hz low pass crossover point.  If you're using a sealed enclosure, then you don't necessarily need a subsonic filter, but it may not be a bad idea.  If it's adjustable, set it around 20 Hz.  Now do a search in this forum on gain setting and make sure that's good.

    yeah unfortunetly it is in a pre-fab sealed box, which dosent help me much and not to mention i did the dumb thing of buying 3 instead of a simple 2 or 4, but i think i need to get a bigger n better amp like ive been told
