amp problems!

[saints_sound]

i have a midrange amp a lanzar dont knw which model but its a two channel amp .. i am getting engine noise from the amp ...its not the ground i changed the ground and also cleaned the ground ... i changed the rca same ting ... so i took out the amp and put in a small boss i had home with the same rca and same ground and no engine noise so i came to the conclusion that the amp is the problem ? any one knw wat is causing the problem in the amp and if it could be fixed ?

try running your rca on the opposite side to your power or just buy one of those ground loop engine noise insulator or summin so and that should solve your ptblem and also check your input jack and see if they are touching d body of d amp

Ground off the RCA behind your head unit.

Try turning down the gain on the Lanzer, if the noise don't go away it could be your deck or another processor before the amp. Try it and let us know. It's a process of elimination.
