Crossover or not?

New Pyle PLMRA400 400 Watt 4 Channel Marine Boat Amplifier Amp Waterproof White 689076539593 | eBay

So I got this amplifier and it looks to not have a built in crossover and I was wondering if I really need a separate crossover to bridge a Chanel to run a subwoofer and a 2 speakers. The amp will be connected to a sony cdx-m30 marine head unit. I'm not sure if the head unit itself can designate the low frequencies from the sub input or not?

Thank you in advance

no, the head unit does not have crossovers and neither does the amp. you can buy an external crossover between the head unit and amps.

you need crossovers somewhere or it will sound poor and you will lose available volume due to distortion. you bought one of the cheapest amps you can find, hence your issue. you should have spent that money on a used amp and been better off. marine amps aren't necessary since they shouldn't ever get wet anyway and a boat is not more hot or humid than a car trunk.
