you should take a look at your ground when i bought my amps locally they offered free installation and after a week my caps after my second battery were reading 8 volts found my ground sparking with any slight move i scraped the paint and slammed a self tapper in there and bam ground for life yes big 3 coming soon for me i already have 2 batteries but only 95 stock ford amps ive seen the meter go over 200 somehow though ima kill it haha put your amp on an oscilloscope and get your self a sweet wave no lines and you pounddddd
