Depending on the smartphone (Android), the unit may not be operated with an AOA connection. In this case, use an OTG connection. The OTG connection requires a third-party USB cable (both USB Type-A Male to Type-A Male Cable and USB OTG Host Cable).

Powered car subwoofers are one of the best types of car woofers on the market.

They already have a pre-amplifier inside and can output a decent bass that can sometimes rival much more expensive dedicated bass systems.

Best, you do not have to worry about additional purchases like a dedicated amplifier. Moreover, a powered subwoofer is an ideal choice for owners of small cars that have a small boot.

Additionally, beginners who have never installed their own car audio system before will love setting up a powered woofer. ( We always reccomend having the unit professionally fitted and tuned )

It has a number of audio outputs that is very easy to connect and fun to play with.
