Car Stereos: after market radio malfunctiom, 2007 nissan altima, nissan altima

Question
Hi I have a 2007 Nissan altima and I was changing all my interior speakers, and halfway through everything was fine, but when I finished and my Kenwood ddx419 wouldn't turn on, and I never touched it! Check the audio fuses on the radio, inside the car and under the hood ans they are all good, what could be my issue?

Answer
Hi Martell,

The speakers you replaced -- are they connected to the amplifier that's not turning on?

If so, disconnect the speakers one at a time, you may find that one of them is either broken, or shorting out.

The amplifier may be turning itself off to protect itself from damage because of too low of an impedance.
