Question about JBL GTO 301.1 Car Audio Amplifier
An active crossover is needed if you plan to do a 2.1 or 4.1 or 5.1 setup.
Check if you have a subwoofer output from your head unit (most later models have). If there is, you might not need an active crossover anymore, but it depends on how you like the sound quality of the separations (low, mid, high). Please note the speaker polarities too.

Passive crossovers are easy to install. By definition, the only type of connections they require are to your speaker line. They typically get installed between the end of the speaker wire and the speaker. Connection should be fairly simple, just like hooking up the speaker itself.
Now F-Mod crossovers modify the audio signal before it is amplified. They accept the patch cord from your receiver on one end, and then plug directly into the preamp inputs on your amplifier. They are also easy to install, and don't require additional wiring.
An active crossover requires a little more work. You have
to connect 12-volt power, ground, and a turn-on lead. The active
crossover gets installed between your receiver and your amplifier. A lot of
active crossovers have both speaker-level and preamp inputs, so they
can usually work with either type of connection. The outputs will be
preamp connections to your amplifier. Hope that helps.
