accounts3 Posted March 14, 2011 Share Posted March 14, 2011 To be precise you really need to measure what your system is drawing, or go for the maximum size the manufacturer recommends Quote Link to comment Share on other sites More sharing options...
FastCar Posted March 14, 2011 Share Posted March 14, 2011 A 3amp or 7 amp will do fine..these are slightly dearer , but last longer. http://www.securitywarehouse.co.uk/catalog/index.php?main_page=product_info&cPath=36_46&products_id=113 Quote Link to comment Share on other sites More sharing options...
