Best For budget friendly person: Pyle hydra Marine Amplifier

Buy on Amazon

Not everyone likes to purchase amp for their regular usage, but the pyle hydra marine amplifier would be an anomoly. This AMP gives some nice bass to it, although if you really want to kick in hard you should get a more reliable brand one. It is constructed with gold-plated speaker output terminal connectors as well to combat corrosion with long term use. The difference between this amp and just the radio's power output is noticeable but not overpowering. The power is clean and the sound roaring out of the Infinity 6x9s keeps the river jumping. The amp is really easy to setup and configure. It comes with dual adjustable input gain level controls between 4 to 8 ohm speaker impedance. The sound is absolutely amazing.

Why We Like This:

Great amp, little longer than the 4 channel, sounds great
Simple connection, light weight, nice clean look, adjustable power output, great value
Uses either bluetooth or auxiliary chord or usb

Best For Harley: NVX 500 Watt Marine Amp

Buy on Amazon

The Marine-v series amps are capable of being installed anywhere and everywhere in your vehicle. This means smaller heat shrinks, less power draw from your vehicle’s charging system, and smaller internal components, allowing for a smaller overall footprint. It is good for a harley or something small. This is a decent amplifier because it does sound good and it is small and can fit into places most other amplifiers just cant.

The best most efficient amplifiers can only achieve about 90% efficiency so that rating then drops to just 367 potential watts before the fuse blows. It is made for an extremely limited work space. Whether you are installing it in your motorcycle, utvs, atvs, boats, and golf carts, the marine-v series amps will take up little space.
