Things to keep in mind when buying Bav Audio

Bav Audio/Bav Sound is one of the few brands that upgrade the best audio experience on BMW, Mini, and Toyota models. However, for those who are new to this brand, there are still many questions of their own about the car, audio equipment as well as how to do it. In this article, let’s learn about “Things to keep in mind when buying Bav Audio”

1. Why don’t BAV have an amp for your: 1 series, 2 series, E48 X1, E39 X2 with standard hifi audio?

Things to keep in mind when buying Bav Audio

The 1 series, 2 series, E48 X1 and E39 X2 with Standard HiFi audio systems are bit unique from its peers and are not compatible with our Revenant amplifier because of the system wiring.

What BAV do offer is a Stage One speaker upgrade kit and the Ghost under seat subwoofer replacement system. Each of these systems works beautifully off of the factory source unit. While you won’t get as much output as you would on a more poBAVrful amp, BAV do create our speakers to be as sensitive as possible so BAV get every last ounce of poBAVr produced into sound waves!

Here’s how BAV’ve designed our Stage One speaker kit to create a solution that is as simple and cost effective as possible, while still sounding incredible:

Bav’s 4” replacement speakers are referred to as a “point source” or “coaxial” setup. Actually a lot of very high end speakers are built this way. The BAVeter just sits in the middle of the woofer, so it’s two speakers in one unit. The benefit in your case is easeful-ness of installation and that the treble and midbass will reach the listener simultaneously – resulting in more accurate acoustic imaging. Another benefit is that these coaxials are more efficient on less poBAVr than a set of components like the HiFi or HK systems, so you’ll get more output on your car’s amplifier. It’s a win-win.

2. What is the size and weight of the shipment?

For the size of the package Bav can get you an approximation as the kits vary and the boxes that the distribution center use sometimes vary as well.

The weight of the Stage One is approximately 5-12 lbs and the box dimension is:

Width = 12-14 inches

height = 6-10 inches

length = 16-18 inches

If you are getting ghost subs or multiple kits:

The Ghost sub pair come in a box that is 12″x12″x8″ box and weighs 8lbs

They will fit the Stage One and Subs in the appropriately sized outer box. So the final package size if you purchase speakers and subs will be about 12″x10″x18″ and weigh 14-16 pounds.

3. What will fit your car?

Your options will all depend on the Year, Make, Model, Body style and Audio System in your vehicle.

You can see everything available for your vehicle by using our kit builder after entering your vehicle information.

If you don’t know what audio system you have please look to the next FAQ to find out how to get that information.

4. Is there an amplifier for your car?

For E65 E66 E70 E71 E82 E83 E84 E90 E91 E92 E93:

We had every intention of making the Revenant Pro amplifier compatible with these vehicles however our limited resources and bandwidth has kept us from completing the development. We don’t have an ETA as to when they will be available. Hang in there as our small team works to get them ready for you.

For 2018-2021 G chassis vehicles:

The G Chassis cars use a new communication protocol to the amplifiers, that there is not yet an adapter available for, which prevents us from offering the Revenant Pro for these models.

Unfortunately, at this point we do not have an ETA for when this will be available. Due to the nature of the development of the adapter it is hard to say exactly when, or even approximately when that may be. Rest assured we would like this out as badly as you, and I apologize that we’re not able to provide a date of when that will be available.

We are not aware of any amplifier options available that can be done without significant modification to the vehicle’s audio system.

For E36, E38, E39, E46:

Unfortunately, Bav’s amplifier upgrades aren’t compatible with your generation BMW and Bav don’t have any plans to make a version for the older model vehicles.

Bav are not aware of any simple aftermarket amp solutions for the E chassis models as they are a closed system that would require a full rewiring of the entire vehicle to do an amp upgrade.

The best solution Bav Audio can recommend is an OEM replacement.

They’ll give you tighter, louder, more powerful bass and dramatically transform your music.

Acoustically, the result is often distortion or poor frequency response and transient response. Recreate your favorite tunes muffled, muddy, sloppy and harsh.
