power on the HU and volts drop to 7.00 WTF I had sys running , then had to remove it to send to the truck <van> to the shop. Now, when I reinstalled it , the relay turns on , fan runs but the power to both amps drops from 14.03 to 7 volts across the power connections at back of both amps . No fault lights, no power lights, no sound, no majic smoke .... Polarity checked and rechecked. What did I miss ???

 

shitty grounding job either at the battery or where the amps are grounded to the frame. that is the only cause of this.

 

K to late tonight to do anything now . Will ckeck 'em in the morning. Thanks

 

Yep, I'm with Prolifik on this one. Check all your grounds.

 

Truck went to shop for no start prob. They said alt went south . They said they had never seen that in a truck so new. Leased and warrantied. YEH HAW. I reinstalled box and had above prob. Ground cable had enough slack to go to alt mounting bracket AND tah da TUNES AGAIN ! THANKS guys !!!:

 

glad to see it worked out for ya
