  • If sound changes check filters
Size: 1000 Watt Class A/B 4-Channel
It worked great until one morning the sound was massively distorted and there was a huge amount of bass coming over the speakers. Finally figured out the hi pass filters had failed. Turned filters off and sound was great again. Unfortunately without the filters active the sound is wrong for door speakers. ... show more

  • Skar is fudging their SNR numbers
Size: 1000 Watt Class A/B 4-Channel
There is a absolutely no way this has a 105 db signal to noise ratio. Any time it gets a signal, you hear a hiss over the speakers. If you're listening at a lower volume level, you can hear the hiss and it makes the music distort. It sounds alright if you're listening at a higher volume level. After I had it installed for a few weeks, the fan started rattling, and I wound up exchanging it and putting in a JL Audio RD400/4 which has had much better sound quality. ... show more
