Local research for a company to do vehicle soundsystem installation

There is a kind of obscure type of car speakers that are called "bass shakers". These speakers don't generate sound waves that are sent into the air, but instead should be hard-mounted to the hull and send vibrational waves through the body of a car (or other object). If you are not familiar with this kind of speaker, or with any general car soundsystem issues, you are expected to include some generic research time to familiarize yourself with these products, as part of this project. The installation of such speakers is not a standard task, and so requires additional research to find appropriate firm/mechanic that would take upon themselves this task. The research is to be done on the internet first, as far as it would be possible, and then, upon generating leads, through personal contact with the firms through telephone or e-mail or similar. This is the nature of this project. Additionally, proposals from firms are to be collected and compared. If no big firms will be found, proposals from smaller companies or even individual technicians might be accepted. It might be possible that you'll have to negotiate some kind of manual deal with them, if they happen to not have such an installation service as a part of their regular repertoire, but could still be persuaded to perform the installation as a custom job. You are expected to get creative on finding a solution. More details will be provided.
