Ok starting out I ordered a 5 channel amp they said 2 day shipping I got it 4 days later when box arrived there was about 6 inches of space inside with minimal protection for amp, factory amp box showed banged around damage, I had best buy geek squad instal amp the 8 speaker wire hook ups was bent-loose anyway as soon as they turned it on it smoked out DEAD! I called as I wanted a refund they said no credit only because was hooked up! How in the Hell are you to know it's bad if you don't hook it up? Cost me over $11.00 to return to them over there junk WRONG on every level,,,so anyway I had them send a replacement AND same issue box beet up bad, no popcorn protection inside box this amp does work BUT it was not new very obvious signs it was not new after I originally paid for a new amp also took a couple weeks to recieve the replacement,, IM DONE, WILL NEVER ORDER ANYTHING FROM SONIC ELECTRONIX AGAIN!
