Default Disable mids and highs in 3-way 6x9 speakers

I have a basic system in my 2019 Corolla and I am keeping the factory head unit. I replaced the front speakers with a component set (transplanted from my previous car) that sounds very good to me. I am going to replace the rear factory speakers with a pair of 6x9 's (that happen to be 3-way) so that I can get a little more/better bass. I mostly listen with the fader favoring the front speakers. My questions are if I don't want to hear mids and highs from the rear, can I simply disconnect the exposed 2 conductor wire that goes to the coaxial mounted mid-and tweeter? If I do this would it change the overall impedance of the speaker to the point where it could damage the head unit?

Or, is there a better way to do this such as by putting a coil in line with the 6x9 speaker to act as a low pass filter. If so, what value coil should I use (mH) and where might I be able to get one. Thanks in advance for any help.

I don't see any problem with cutting that wire, just cut it in a place where it can be reconnected later, if the need arises.

Cut away, done it before, the impedance won’t get lower 👍🏼

Cut tinsel leads no probs, but unless you have some kind of LPF (Low Pass Filter) the 6x9 cone will still do a surprisingly good job of high and mid frequency reproduction.

An inductor in the speaker wire would be easiest, not sure if an OEM head unit would power the speakers with this in place? Passive components soak up some power and OEM head units don't have much to begin with

Many thanks. Did cutting the wires help to reduce some of the high end brightness?
Also, I am assuming that I would only have to cut or desolder one wire of the pair, say for example the positive wire, or is there some reason for why I should cut both wires of the pair?

No need to do both, one will do the job.

www.parts-express.com

will have everything you need.

www.diyaudioandvideo.com

has a good crossover calculator to help pick the value you need.

Or if your up for it a basic 4 channel amplifier will have a high pass and low pass adjustable crossover built in.

An inexpensive option would be the Dual XPR84D. Available at Walmarts around the nation at less than $100. Don't let the low price fool you, as its a pretty good little amp. Check out the test on youtube.

Did it help to reduce the the highs and mids (brihgtness) of the speaker?
Was it worth doing this? Thanks.

dont get those 6x9s and get these 6x9s instead. You can get a low pass inline crossover on parts express too.
