2005 Acura TL Audio Amplifier. Sold as is need capacitors replaced. It's a cheap easy fix. It did work. Just had random low volume issue, I replaced with a 2008 unit. My TL is long gone, sold it in 2020. Figured if someone had the same issue and wanted to repair the unit you can with this and easily swap it out. The capacitors are only 15 dollars. There is a link on the repair on Acurzine or one of the acura forums.
