What’s to like about ​it:

Power Acoustik products are known for their reliability and durability, and this model defines those expectations well. It’s also got one of the highest power outputs available on the market; any larger, and you’d kill your car battery very quickly.

What’s not to like about ​it:

This amplifier is heavier than many alternatives, and bigger as a result of its incredible power output. This reduces the options for where it can be installed within a vehicle. The power output also demands a lot from your car’s battery; you’ll need to have upgraded it, and potentially have a secondary as backup.

PROS

• ​Excellent durability, trustworthy brand
• ​Largest power output of those we’ve looked at on this list

CONS

• ​Larger and heavier than others
• ​Will rapidly drain your car if other components aren’t up to scratch

Despite having been around for around 15 years, this amplifier is still compatible with more modern vehicles.

What’s not to like about ​it:

Part of the problem with this model, and indeed probably partly the reason that the product is so inexpensive is because it doesn’t have sub plugins, only speakers. It also lacks the inline connector plugs required for the four channels; these must be bought separately.
