To bridge or run conventionally

Hi guys. Total audio nube here. So I put a amp and speakers in my Harley motorcycle.
The speakers are db drive wdx6moto witch are 300w speakers with the power handling of 150w per and 4 ohm. I have 2. My amp is a massive blx44. 4 ch 2x480 max . The manual don' give much info. But if I run bridged it would put out 480w and if I don' bridge it would be 120w per speaker. I have some say to bridge it and some say not to.
Trying to surch how to set everything up is mind boggling lol. I' very lost. I just don' want to blow something.any help or advise would be very much appreciated.

Bridging amp raises the wattage quite a bit, but that’s where the advantages end.

1: Distortion goes up,
2: Output impedance is higher (damping factor lower), which means bass is not as controlled.
3: The ability to drive below low impedance’s takes a hit.
4: The amp becomes more unstable..

If you don't bridge it, you wasting 2 channels.  However, many times bridging an amp will increase distortion levels.  You can very easily try both ways.  You should get a lot more volume bridged.  (just make sure you disconnect the power before bridging).

If you bridge, you turn 2 channels into 1. 

So, you need 4 amp channels to produce 2 speakers worth of output.

Best,
