6 speakers (4+2 tweeters) with a new 4-channel stereo?

[Sparvass]

Hello! Confused and clueless person here.
I have a Toyota Avensis T25 2005 with the original car stereo. I've been looking into installing a Bluetooth/AUX adapter, but since this seems to cost about the same or more than simply installing a new car stereo, I'm leaning toward the latter instead.

I got a bit confused because the car has 4 speakers (in the doors) and 2 tweeters in the front, while new car stereos are 4-channel, typically 4x50W. Will all 6 speakers in the car work in this setup?

Are the tweeters usually wired together with the front speakers, so that this won't be an issue?
Are there any other potential problems with installing a new stereo while keeping the old speakers?

What you have are called "component speakers." It's where the woofer is separate from the tweeter. The typical speaker you see, where the tweeter is located in the middle of the woofer, is called a "coaxial speaker."

Component speakers come with crossovers. The crossover will separate the frequencies between the woofer and the tweeter. The crossover will have one input, from the stereo, one output for the woofer, and one output for the tweeter. In you case, the factory speakers have the crossovers/capacitors mounted on the tweeter. Your woofer are not crossed over.

An aftermarket radio will say 50x4, but it's really about 17x4 watts. However, your car might have a factory amplifier in it, so you will not be using the power from the new radio, unless you bypass the factory amp.

Also, you would be a lot happier with a double din aftermarket radio over just a BT adaptor.

Thanks for the very explanatory answer, made me a little vit wiser, but also, a little bit more confused. So to sum it up a new stereo could work, but it's not completely sure? Depends a bit if the car has an factory amplifier already installed?

A double din would definitely make me happier than the adaptor.

You can still use an aftermarket radio with the factory amp. You just need a special adaptor.

Anyway you can point me in the right direction to what kind of adapter? If it's now needed. Have to figure that one out first.

I am not too familiar with that car. The biggest question is, does it have factory amp. If you Google the amp location, for your car, take a look to see if it is there. It might be in the trunk, but sometimes they put it behind the dash.
