Okay I have a 4 channel mtx amp the road thunder 400 watts max and 40 watts rms per channel at 4ohms and 75 watts at 2 ohms or something... My 6.5" Infinity referance speakers that I Will be running say that they are 4ohm speakers.... How do I wire these so that they are 4 ohms?? I will be running 4 of them... front left, front right, back left and back right doors. Do they have to be bridged or something, or do I just wire them up like Front L, Front R, Back L and Back R and so on.... Sorry for so many questions, just getting ready to wire up my mids tommorow!!

For 4 Ohm just wire em up fr left fr right and so on and so forth as you said!

Thanks man!! [img]smile.gif[/img] So is it okay to run 4 ohm infinity referance speakers at 2 ohms?? And if so, how would you wire it so they would be 2 ohm and be running at 75w rms!! [img]smile.gif[/img] Sorry for the 20 questions! [img]tongue.gif[/img] [img]redface.gif[/img]

With a speaker on each channel of the amp (front left, front right, ect.) you will have a 4ohm load on each channel. You would need 2ohm speakers to run the amp to get all the power out of that amp.

This is a good site to learn anything you need to know about car audio;

the lowest imp. you will be able to get out of each channel with those speakers will be 4ohm [img]smile.gif[/img]
