[This review was collected as part of a promotion.] I recently bought a brand new 2024 WRX Premium, I absolutely love the car but hated the factory sound system. Within the first free weeks of ownership, I replaced the factory speakers with JBL Club speakers. It was still missing the extra power to push these speakers effectively. I started to research how I wanted to power the speakers and the requirements for what was needed for my specific car. Everyone that I talked to kept recommending AudioControl products to me, so I started to research them. All the videos and articles that I watched on Stinger’s products were stellar and when I discovered that they were made in the USA – I was sold! My radio went from having minimal bass and volume clarity to full bodied sounds and I could feel the music. It was no longer flat and had perfect pitch and this is with the factory radio’s equalizer set to 0 across bass, mid, and treble. I highly recommend their Line Out Converters and amplifiers to anyone looking to upgrade and improve their car audio listening experience.
