  • Spend your money wisely don't just read what it says and go off of that this is BS
Model: A-SIAV23500
It says it's a 3500 watt RMS amp amp but this is not a 3500 watt RMS amp. This does not pull out the pressure like it's supposed to 3500 Watts it's supposed to sound way better than this this sounds like a 1500 watt amp very poor. I didn't like it the bill quality was not all there the durability was very heavy so I guess it was strong enough the heat the amp never really got hot because it wasn't doing anything not worth the value of your money ... show more
