ok i fixed the issue>>the pwr wasnt going to the amp cause of corrosion of the fuse next to the battery. anyways another problem arised. the sub now makes noise like squeeling, but it still pumps. so when i turn the volume up, its ok i cant hear the squeel but when the volume is down or 0 i can hear a squeel coming from the sub. Also when i start on the car with the volume on 0 i hear like the engine noise kinda thing pumped through my sub, what u guys think it is? mayb i try record the noise?
