Long time no see fellas I have a taramps smart 3k, 270 amp alternator, 2-4 ohm sundown sa 12's 1500w 0 gauge throughout, the big 3, and a xs power d3400 under the hood. The clip indicator that came with the amp literally fell apart in my hand and even then it was extremely sensitive. I should be louder than what I'm hearing my installer keeps telling me I'm at my max and properly tuned. He tells me that my car which was considered a semi luxury vehicle during its time on the market has a lot of insulation blah blah blah. I drive a 1999 oldsmobile eighty-eight and though there is some extras its not like a Cadillac. Its a lot of clipping and 3k should sound louder than this
