Alright well i have had my system out of my truck since a couple months after i bought it because of the strain my alternator is going through. I have a 4 cylinder nissan frontier 2002 and am looking for a high output alternator. My problem is i dont know what level of Amps i should be shooting for. Also if you know any great sights to buy an alternator from i have been desperatly looking and am hoping to pay less than 450.00. Thank you for any help you may have
