Due to the ongoing and evolving "LOCKDOWN" situation in place since early 2020, we are anticipating a small delay in processing of orders and subsequent shipping due to a reduced workforce, in both our warehouses, and those of our suppliers.

Whilst we are trying our best to continue in a business as usual, we must again close our retail showroom doors temporarily to support the Governments COVID19 Strategy. Throughout this temporary closure we will still be shipping items from our warehouses and those of our suppliers, but it may at times be subject to a small delay.

Product Description

Fully waterproof 5 channel marine amplifier with Shockwave Technology™.

Shockwave Technology™ brings together outstanding sound quality, high performance characteristics and unprecedented reliability into a 4/3/2 channel marine amplifier.

Waterproof marine grade – protected against water and dust with an Ingress Protection rating of IP65 means you can literally hose down our Shockwave Technology™ marine amplifiers, thanks to a number of unique features exclusive to Aquatic AV (patents pending).

The 5 channel marine amplifier features conformal coated circuit boards protect the smallest components from any humidity or atmospheric moisture, while custom molded grommets around cable extrusions and gaskets between all meeting points eliminate any chance of water or dust intrusion.

Designed to support the widest variety of applications, Shockwave Technology™ marine amplifiers operate both 4ohm and 2ohm speaker configurations from RCA input connections. Running 2ohm configurations allows more speakers to be powered and ideal for high background noise environments such as marine or boat applications.

Shockwave Technology™ incorporates Digital IC’s with specially designed low-noise circuitry to produce high-quality, true sound reproduction from any source.  The technology used also reduces unwanted EMI (Electromagnetic Interference), which can cause noise in your audio system.

Digital amplifiers are much more efficient than traditional amplifiers; producing less heat, lowering power consumption, reducing strain on batteries and charging systems, and ideal for marine and boat installations.

Shockwave Technology™ is now the only sensible marine amplifier solution for marine or boat applications.
