I installed 4 new 90rms in the front and rear doors and just bought a 4ch Lanzar 412 amp to power them, heres the issue, can i hook these speakers up the normal way so the amp sees 4ohms which will send 125w to each speaker?

Most any amp will be stable into 2 ohm loads for each channel, just don't try to bridge the two pairs, it would only be stable at 4ohms... technically... but it would most likely be able to run at a 3ohm load even if you bridge the channels, so a 3ohm speaker running from each of the 4 channels won't do anything to the amp, other than "theoretically" putting a lower load on the amp, creating more power available to each speaker.

But, as Dylan asked, did you run new wires from the amp to the speakers? The stock wiring will only handle maybe 40 watts MAX, if you try to run 125 watts through them, they'll most likely melt.... and short out.... and possibly start a fire....

Yes, I did sun new wire from each speaker, not sure what size the wire is that came with the new speakers but its thicker that's for sure...jus wanna wire them safely since they're rated at 90w rms per speaker, and at 4 ohms the amp puts out 125w per channel, so I'm sure I'll have to leave the gain lower.
