So I'm going to change my car audio system to the following:
Woofer/Midbass: Dayton Audio RS180-4
Tweeter: Dayton Audio ND25FN-4
Firstly, does this combination seem good? Looking at the frequencies and from what I've read about the RS180-4 drivers, they need crossing over about 3khz for best performance and the tweeters should be okay crossing over above 2.5khz.
I've had a go at designing a crossover on xSim and wondered if the more knowledgable on the forum could point out my errors.
Any help would be greatly appreciated!

Thanks. I should have said, I've never made a crossover/diy speakers before so this is all new to me.
I'll give your thread a nudge in the hope that the crossover design experts will pick it up. 🙂
Seems to me that there's a hump of around +5dB around the crossover frequency which may be worth taming.

You could go second order, unless you need a steeper curve to protect the tweeter.
Start with something like this. If you really want to tame and refine it, you'll need direct measurements of your build.
That tweeter really shouldn't be crossed lower than about 3K, but the woofer has serious breakup an octave above that. So it's tricky.

I appreciate the feedback.
I've bought the woofers but haven't got the tweeters yet so I'm open to suggestions.

What are your limitations? Since it's a car, I suppose the tweeter needs to be small.
Any budget restrictions?
Also, will the tweeters be close to the woofer or will they be placed far away such as on a door pillar of the dash?

My budget isn't infinite and it's in a car with some sound proofing but my no means is it a truly quiet listening area. The tweeters are in the front corner of the window at the top of the door card and the woofers are at the bottom. Size is fairly important as I want the tweeters to fit behind the factory grills.
That being said, I would like the best match for the woofers for a nice clean, detailed sound.

OK, I'll have a look. Might be able to sneak the tweeter crossover down some. And the woofer will be heard far off axis, so that makes a difference.
Yes it's OK and often desirable.
That said, your woofer is the one with a lot of out of band junk and break up. At least on-axis. Go at Parts Express to download the FRD files and have a look at the off axis response. That's where you'll be hearing the woofers, not so much on axis.
