DS18 V2HL.V2 Hi/Lo Converter 2-Channel with Speaker Emulator - High-Level Speaker Signal to Low-Level - Smart line Output 2CH High-Level Input and 2CH RCA Output

The best Hi/lo converter I've ever used and I've used a few. I used this on a 2021 Camry SE (no jbl audio) I added a Red Wolf t-harness and connected this DS18 to it.perfect no amp winding, no need to find remote wire, because of speaker turn on.. worked awesome. Definitely recommend.

no complaints. sounds great. very compact and easy to hide. i snatched the signal from the rear speakers under the parcel shelf so i simply ziptied it underneath. very easy, secure, and out of sight. sound quality is excellent as well.

Perfect

We purchased a 2025 Silverado. It was lacking a little bass. So we decided to add a 10” sub and amp under the seat. This converter was exactly what we needed to be able to retain the factory radio and steering wheel controls. Sound quality is excellent. Couldn’t be more pleased. Installation was straight forward.

Let's the sound signals through, but for some reason amp won't shut off (remote wire is keeping 12v). This makes no sense to me since the only power it has should be coming from speakers but it certainly is doing it. I saw another users review with the the same problem. Will be sending back.

Used this to add a subwoofer to an RX-350. Works great! I really only am using it for a remote turn on.

It does what it says it'll do and converts the signal but unfortunately does not work for me if it doesn't have any sort of signal booster or anything it literally is just the basic

Easy to install no need to look for 12v supply, sound better than previous unit i had install.
