sub to amp wiring? (after market)

I have a 4 ohm KIcker L5 and my amp is 2 channel and capable of 2 ohm load, but all the wiring diagrams show i can only wire the sub to a 4 ohm load (bridged) but if the amp were mono block then it can be 2 ohm load. dont make sence to me. whats the difference "mono or bridged"? the same isnt it (out put wise)? get wat im saying?? If you bridge an amp it is more less considered mono"ed" or what ever right. omg my head hurts now plz help!

if you wanted to run your amps at a 2-ohm load to draw more power from it.... you would need a 2-ohm speaker or multiple speakers that you could wire into 2-ohms. if you have a single 4-ohm speaker, you're pretty much limited to running it @ 4-ohms.

is it a single or dual voice-coil speaker?

It is a dvc kicker l5 1200 watt max 600rms. I hav found many wiring diagrams and it show if I had a mono amp the 4 ohm dvc sub can be wired at 2 ohm but it shows that on a two channel amp it can't be done by even bridging it. That's what don't make since to me. What is the difference between a bridged amp and a mono block amp?

Basically when you "bridge" an amp your wiring both or multiple channels together to help each other produce more power. So most amps are only capable down to 2 ohms per channel. If you were to bridge an amp down to 2 ohms, each channel would be running at 1 ohm and would probably burn it up. Your best bet I think would be to wire each 4 ohm voice coil to each channel. If you want more power I would suggest either buying a mono amp or getting a dual 2 ohm sub.

thanks

i think i may have misunderstood what you meant when i first read your post....
if you want to take your amp and bridge it into a 2-ohm load on a 4-ohm DVC sub, it's pretty simple, all you have to do is run the 2 voice coils in parallel, like this:
*see attachment*

See iv looked at a few wiring wizards/diagrams and you can wire a 2ohm sub with mono amp to a 4 or 1 ohm load and the 4 ohm subs can be wired to a 2 ohm load or 8 ohm (I think) but that's what I can't figure out. With my amp bridged it puts out a 2 ohm load but the wiring diagram ses with a two channel amp you only get 4 ohm (pushed to the sub)bridged.
Another question is how much difference is there in spl and sq between 2 ohm load and 4 ohm load. I know that when you have a lower ohm"age" or how ever you say that" you get more sound pressure level but how much more you get from a 2 ohm difference(I'm a spl guy)? Can't be too much can it? Jinxie I just blew a kicker l7 10 by wiring it that way that's why I'm asking about this. But that's the way it shows to get 2 ohm load with mono. So maby my amp does puxh one ohm but not stable enuff to keep from blowing the sub??? Hmm that's a thought.

mono or 2-channel bridged is irrelevant. if your amp is stable @2-ohms bridged, then you should be fine wiring it that way... as far as SPL increase, there's no way i could tell you that. the true spl that you'd get would be determined by a lot of different factors (box design, interior of your vehicle, amount of power your amp is really putting out, amount of current your amp is drawing,etc.)
if you really want to know, i would suggest seeing if a local shop near you has an spl meter that you can use to test it with.
