Help Choosing a New Stereo

[Engin]

Hi everyone,

I’m looking to replace the factory Bose stereo in my 350Z, and I’m currently considering two options:

1. Kenwood DPX505BT
2. Kenwood Excelon DPX795BH

The main difference seems to be the preamp voltage: the DPX505BT has a 2.5V preamp output, while the Excelon DPX795BH has a 5V output. Unfortunately, I have no experience with sound systems and don’t know how this difference might affect sound quality or compatibility with the factory Bose amp.

I also vaguely recall something about the ohm values of head units when replacing the Bose system, but I’m unsure how it applies here or what I should watch out for.

I’d really appreciate any advice on which of these units would work best, or if there are other better options. My main priority is to keep the car as close to original as possible, so I’m not interested in anything with large screens or modern-looking interfaces.

Thanks in advance for your help!
