Hello, I’m double checking some advice Crutchfield gave me. I want to improve the sound in my non B&O system to get better quality and depth. I am planning on a Kicker Key 180.4 and replace the door speakers. If needed I was thinking of a 8” powered Kicker sub behind the seat.

Crutchfield recommended Polk DB 652’s https://www.crutchfield.com/I-rETNc108/p_107DB652/item.html front and rear with the stock tweeters left in place.

I’m not an audio guy but I do enjoy good quality sound...or Better than what I have now. With that amp and speakers, how important are the tweeters in the scenario? Any alternate choices that the audio guys on here who think might be better?

Thanks. I’ve got some time on my hands now so I might as well do something.

Just remember highs are directional so a more vivid separation. And the bass goes everywhere.
I think tweeters are needed. Especially on some audio stations.
I've noticed XM & FM radio sounds mostly flat with stock speakers on my non B&O, but when I plug in my phone or use my jump drive, it really wakes up the stock system.
My future plans are go with your choice which is a good one.

Thank you. I do not listen to radio stations much but do listen to SiriusXM and my iPhone. The satellite radio really is pretty flat sounding. Thank you

I would never recommend installing coaxials in the doors and then leaving tweeters in the pillars. If that's what Crutchfield told you to do, that's just plain bad advice.

What happens is you have two drivers producing short wavelength sound at the same time which interferes with each other as they get to be different distances from your ears. And it gets worse at higher frequencies.

The effect is called comb filtering. And your effective frequency response in the range where both tweeters operate will look something like this:

Move your ears a couple inches and the peaks ad valleys move to different frequencies.

So in summary, if you want new speakers up front get separates and work out a way to replace the tweeter in the pillar with the new one. One tweeter per side is the only way to do it.

Thanks @Zaph You understand this a lot better than I do. Would unplugging the tweeter and going with the recommended speakers be a decent option or better to go with something like this . The reason for wanting to avoid a tweeter was because it looks like they cannot be plug and play or done without damaging the factory harness. To be honest, I have not pulled the little cover over the tweeter to see what I am dealing with yet though.

Well it would be a more workable option than leaving the tweeter plugged in, but consider that having the tweeter in the pillars does wonders for soundstaging and imaging. I'd highly recommend proper separates over coaxials with a disconnected pillar tweeter.

There are some folks around here who found unflanged tweeters that will fit inside the original tweeter's mount, without cutting. Have a search around the forum and see if you can find them.
