I recently purchased a crescendo symphony mono block amp along with a 10" audiopipe sub. It worked great at first. Then I noticed it would cut out in the morning when its cold. After 10-20 mins of running it at low volume it would go away. Now it isn't doing anything. Checked the fuses. Remote wire, and leads and found nothing. Is there a chance it could be blown? Its almost brand new and hasn't been abused at all
