Default ML Speaker Swap Ohm Problem

Okay I'm trying to swap out the OEM ML 6.5 in the front doors...the ML 6.5 is 8 ohms. The new 6.5 is 4 ohms. Is this going to over load the factory amp? Has anyone had problems yet? Thanks

It is hard to say for sure but in general, yes it has a good chance of overloading the amp. Typically, the amp would become too hot during use and go into a protection mode by turning off the speaker outputs.

I have not tried it so I can say for sure but I just doubt that the amp would be stable at 4 Ohms if it was designed for an 8 Ohms speaker in the doors.

Hopfully somebody else had tried it and can confirm (or not) my words.

Yeah thats my thinking on it as well....But I'm sure some people have swapped to 4ohm speakers and had no clue that the oem's are 8ohm

This still leaves the question, is the amp going to handle the new load?
