Question.

Does DIY really work?

 Answer.

If you can put IKEA furniture together, or believe you are capable of doing so, you will be fine.

TICKEN PACKAGE has been designed for easy installation;

it does not require any wiring or modification, included tools can lead you through the beginning to the end of the installation.
You could unplug the OEM speaker, place the TICKEN PACKAGE,

and plug the TICKEN product at on the connector; like you would with LEGOs.
All TICKEN PACKAGES will come with detailed manuals that you could easily follow.
(Detailed videos will be made available soon.)
