Bit of Background Noise, but Nice Little Amp
Installed with Soundstream VRCP65. Nice little amplifier. There is a bit of background hiss probably because of the ~70 Signal/Noise rating, but it does what it says and was an easy install and fit easily in a hideaway location in the dash where the factory amplifier was removed ( LX450).
