Audio Upgrade for BMW X5 E53

If you buy a component set, it will come with passive crossovers. Just hook them up per the instructions. Pioneer diagram below.

Yes, I meant those crossovers. I wonder how they connect, the left side of the speaker connects to one crossover and the right to the other or does it all connect separately (front left to one rear left to another, front right to one and rear right to another)? How many crossovers do I need

Sounds like you should do some reading on audio forums as an intro before purchasing. This can get be complicated, or very simple.

A simple way is to buy component speaker pairs. They will come with 2 woofers, 2 tweeters, and 2 crossovers. Left front woofer and tweeter will connect to one crossover, which then has an amplifier output. The other side will have its own crossover. So, generally speaking... each door will have a crossover for its pair of speakers. Generally.

I was thinking of these crossovers with 6 inputs and 2 outputs but I found on the internet how they connect. Did you install the speakers under the seat like the new BMW models have, will that contribute to the sound system?

The short answer is that BMW's modern 3-way system is quite nice.

Why? Because you can install a robust midbass woofer and take a lot of stress off of the midrange driver. A 4-5" driver is generally going to do a lot better for the vocal ranges and is more able to meet the tweeter at the crossover frequencies that it will want. It also lets you take some of the upper range off of the subwoofer.

My crossover points in my E90 M3 are roughly 4500-200-60. With a 2-way setup, you generally end up at crossing the mid to tweeter at 3500, and the subwoofer comes up to 80 (or higher if your mid just can't get there).

That said, getting a driver under the seat requires space that may not really exist in the E53.

to which connector in the crossover the speaker under the seat connects if I were to install it

The crossovers are clearly labeled.
