When the stock system is not doing great, all you need is an extra ‘kick’. And this is what exactly the BOSS amplifier does, years after years. People who love extra bass have highly recommended this if you have a tight budget. 

It won’t rattle your neighbors, but to give your music a new depth, it’s second to none when you do not want to spend a fortune. Yes, you can get it as low as under $100 just like so many cheap car amplifiers out there. But, the quality is simply unmatched for a budget car amplifier!

It will give you more than enough bass and depth to the music consuming the only ⅓ of power.

Apart from extra wires, the monoblock amp comes with all you need to install it successfully. You should ensure enough cooling space for it though to serve you for a long time un-interrupted. 

Install it anywhere in your car and keep it visible and make sure you cover it too. You need to let it breathe properly to avoid overheating, to amplify the music, and to ensure it’s durability.

People with vast experience of dealing with amps for their whole life have confirmed that this is the best budget mono car amplifier they have ever dealt with. It’s sturdy and the housing is made from metal that sounds amazing. 

There are not many car amplifiers that can hold 0 gauge wire. But this one can hold 0 gauge and it’s amazing. FYI: If you have a Skar subwoofer, it will hit so hard that it will bring the true power of your sub. 

It has some negative reviews mainly for 2 reasons. One, they got the wrong specs and two, they simply don’t know how to hook it up. Watch some YouTube videos on its dyno test, then decide.
