high static noise
my front speakers on the trip to the store all of a sudden went static noise, this is a four channel amp gain turned all the way down 4v inputs,
the rca's are good first thing i checked, can't understand why only 2 channels went out. if it went bad
the amp is only running a couple each of 6.5 scosche 2 way's front and 5x7/6x8 soundstream speakers rear, obviously a 4 ohm load. so i could not have over driven the amp.
it is a soundstream 480.4 xstream, lower end yes but i had no probs till today. and very reputable in my area.
anybody have ideas what to check for?

using factory wiring as the speakers dont get that much power or require that much power, and not really worried bout the sound quality.
so my wires are factory harness wires running to them, if they got cut it would be a big surprize.
checking anyway though

Troubleshooting Troubleshooting.
Swap RCA cables F/R at the amp. If the problem changes to the two 'good' channels, you know your problem is with the source or the RCA cables. If not, try these below:
Pull the amp and have it bench tested at a shop.
Put an ohm meter on all the speakers to check impedence and make sure nothing is shorted here.
With the speaker wires unhooked from the amp and from the speakers, check resistence from each lead ( + & - ) to ground. This will tell you if you have a shorted speaker wire.
Your problem should be able to be diagnosed with these measures.

see if the amp and deck, check resistence from each lead ( + & - ) to ground. This will tell you if you have to move your -neg-.
