Ok to make things plain and simple I have 2 10" Infinity Kappa Perfects. I got the MTX 942 2-Channel amp to go along with it. I have the SVC 4 ohm ones. So my question is... Do I have it wired right if i just have it in two channel mode.. since my box came with two terminals. I just have it wired one side the the other. But for some reason it doesnt sound to bassy. Not to say its not good bass.. but I read the manual and it says that it puts out 470x2 at 2ohms and these subs only take 350 rms. So.. do i just have quiet subs for the SQ part of them. Or do i have this set up wrong?.. Let me know if you have any idea. Didnt really wanna ask this and seem like a retard.. just seems like they should be pounding pretty hard.. dont you think?.. oo btw.. i have the gains full.. oo and not to mention for some reason only one gain needs to be up to make them both move?.. whats with this..?
I think the way you have them wired right now is in stereo. Meaning one channel to each speaker. Am I correct in saying this? If so you are sending a 4 ohm load to each channel. So each sub is getting 235 watts rms @ 4 ohms.
Unfortunately, your amp is not stable to 2 ohms when bridged, so that is all you can really do with those subs. If you had 4 ohm DVC subs you can bridge the amp and wire the subs like this.
(option 2)
Then that way you'd be sending about 400+ watts rms to each sub. But since you have single 4 ohm voice coil subs your only option is to wire them in Stereo(edit)
Now by having your gain all the way up, I can guarentee you you are clipping the amp and doing damage to your amp and probably the subs too from distortion.
If you want more bass, you need to either get an amp that is two ohm stable when bridged and that will send more power than what you are currently running. OR you can buy subs that will take advantage of your amps power. You can use 2 ohm SVC subs and wire them in Stereo like you have now. OR you can get 2 4 ohm DVC subs, and bridge the amp.
BTW 5,000th post right here

haha well shit.. that is gay.. but wtf?.. is your ohms the same if you arent bridging it.. cuz i know it says 2 ohm briged so i just figured it would be the same concept for a 2-channel setup?... anyways.. how would i wire it bridged if i decided to get a new amp.. not the acctual running it to the subs like those pictures depict.. but how would i wire it to my box if i have 2 terminals? Or can i just simply run two wires out of the negative and two out of the positive, or will this not be good for the amp??
anyone?.. well anyways.. i got an offer for a Diamond Audio D7401 and a PG ZPA 0.5 which one do you guys think is better or do you think i should get a different one?.. i may just be trading my subs for dual voice coil too but this is my back up in case that fails

Your amp says 2 ohms stable? Or are you refering to what the subs will do when wired together? Because everywhere that I've rear, your amp is only stable to 4 ohm when bridged. It is stable to two ohms, if you were to wire subs in stereo. But you don't have subs that will show each channel in stereo 2 ohms. They will see 4 ohms.
This TN Member is looking to upgrade to a nicer amp. Depending on what ohm configuration his subs are(or what he plans on buying) it would work out nice,

Those are both VERY nice amps, if you don't mind me asking what are the prices?
so wait let me ask.. if i get the Infinity DVC 4ohm subs to replace the single 4ohm ones.. what will my amp be running? the 4 ohm bridged setting or the 470x2 at 2ohm setting that it doesnt list?.. for some reason im having a tuff time understanding these DVC.
ok and what i meant before was... when i got my subs i figured that i would be able to run the single 4 ohms at the 2 ohm lvl because i thought that was the way it worked (amp has to have lower resistance) but apparetly i was wrong in thinking that haha so basically i was asking.. if you have a 2 channel amp.. does the ohms match the amp (ex: my 4 ohms made my amp go 4 ohm split into two channels thus making it weaker).. am i correct in saying this?
oo and one more thing... well i kinda already asked it but.. ok if i get the DVC subs, how do i wire it?... do i just wire it the same way but them change the way i have it to the subs?.. thats the way im seeing it from the picture. But im just confused as to what my amp is doing if it is placed with DVC? is it being bridged then.. or is it still going to be two seperate channels.. sry for being stupid but i really dont know how DVC works at all
From a stereo perspective, when a multi-channel amp indicate they are 2-ohm stable, that means EACH channel is stable to that impedance, meaning, it can drive two 4-ohm speakers, typically midbass or tweeters. You "can" hook up two subwoofers to it, but you'll barely hear anything.
From a monotone perspective, 2-ohm stereo is the same as 4-ohm bridged into one channel. In transistor-level talk, each of the complementary channel is used in a differential mode, thus, adding more power because each gain stage has increased.
Thus, if you get two DVC 4-ohm subwoofers, your configuration is either a 4-ohm load using a series-parallel configuration, or 1-ohm load using a parallel-parallel configuration in DC measurement. Since music is AC, the impedance will fluctuate. If you plan on keeping the 2-channel amplifier, just run it in bridge mode, thus, you can run both subwoofers at the same time through one set of speaker terminals.
Lastly, the lower the impedance, the higher the current draw. It is CURRENT that produces power, VOLTAGE is used for power regulation.
