Good to know

Questions,
answered.

The things people usually ask before choosing a package.

What does azaudioworks do?

We install car audio systems in three packages: DSPM (a DSP added to your current system, with rewiring and tuning), the two-way system and the three-way system. Every install is tuned in your car. A subwoofer, a custom subwoofer box and custom pillars can be added at extra cost.

What does the DSPM package include?

DSPM is a DSP installation with rewiring of the audio cables and a full tune in your car, keeping your existing speakers. It starts from Rp 3.500.000.

What is the difference between the two-way and three-way systems?

A two-way system uses a tweeter and a midbass on each side. A three-way system adds a dedicated midrange driver, so each part of the music has its own speaker. Both include DSP, amplifier, complete cable set and tuning. The two-way system starts from Rp 7.500.000 and the three-way system from Rp 20.000.000.

Is a subwoofer included in the two-way and three-way systems?

No. Both packages cover the front speakers, DSP, amplifier, cable set and tuning. A subwoofer, a custom subwoofer box and custom pillars can be added at extra cost.

What are custom pillars?

Custom pillars are A-pillars made for your car that hold the tweeters (and the midrange on a three-way system) up high and angled toward you, trimmed to match the interior. They are available as an extra on the two-way and three-way systems.
