I'm pretty old school on the car stereo stuff although my last truck had a couple of 600w amps, crossovers, bridges, overpasses and freeways. That truck came with everything already done.
That's my question(s), what are crossovers and bridges on the amps?
My new to me truck came with an ok head unit and Infinity speakers but it's obvious someone took the amps and subwoofers out before trading it in. I'm sure they also took the original head unit out and put this one in. I'm not into a gazillion watts of thumpity thump, just don't want the distortion when I do turn it up a bit.

The bridge is an operation mode. any time you tie two channels together to form a single output it is always referred to as a bridge. not as much an actual piece of hardware just a mode of operation.
Crossovers are used to split the frequencies into a narrow group/s of frequencies
Sub = 16 ~ 150 Hz mid bass 100 ~ 250 Hz. mid 200 ~ 2k Hz High 2k 20k Hz
Or something to that effect. They all differ and some continuously variable.
Make sense ?
