Alpine PDX-V9

Alpine is known to produce some of the greatest amplifiers in the market and the Alpine PDX-V9 is no exception.

The PDX line of amplifiers was introduced a couple of years ago and it has been really successful. This really represents the ultimate in digital amplifier technology. These amps sound great, they are  efficient and they are really small. They are stack-able because they are all of the same size.

The Alpine PDX-V9 5 channel amp is a very powerful package in a very small chassis. It has 100 watts × 4 and 500 watts × 1RMS all built-in to the same amplifier.

It also boasts of an advanced set of crossovers and gain controls that will allow you to tailor that to your system. This allows you multiple systems configurations. You can do a front-rear subwoofer system. You can even do a 3-way bi-amp system all off of one amplifier with no other connections required.

Just like all other PDXs, the Alpine PDX-V9 is extremely efficient and compact. It’s got the removable speaker and power connectors for easy installation and it will fit in just about any car.
