amp trouble
f150 with stock head unit . Insalled 4 polk audio GSX57s in it now installing a profile cl440 amp . Speakers and amp are rated for 50 watts rms 4ohms , through the 4 channels . Has high level inputs , crossovers . Installed today put in amp kit ,everthing good . Can't get speakers to turn up to 3/4 to tune . I bought metra harness 70-1771 (into stereo) wired it with 18 gauge wire ran it to amp under seat . Soldered the 18 gauge to the high level input leads included with the amp. Now it seems sound is bleeding everywhere . Fade and balance to one speaker still bleeds through . Now I have cut all my beautiful connections down to the left front door speaker and can get little to no volume out of the speaker . I'm beggining to think that my solder joint at the amp leads are no good . Please help before I screw something else up !! Any ideas I will take !! Thanks , Mattyb327
it sounds like all your speakers wires are right at the amp
so just connect them as normal to run off the head unit
if it works fine- then check your power wires for the amp
if thats fine your amp is likely toast
