oK i just got a 92 HB and I installed my system . I have a 1200watt V12 Alpine amp , 300 watt v12 amp , an HK amp not in use at this time , and 1 10" JL Audio W6 sub . Headunit is a Alpine as well . interior speakers are stock at the moment . Now what I have a problem with is at around 9-10 on the volume my lights start flashing with the bass . Im gonna go get a cap to see if that helps the problem . Please let me know what you guys think thanks !
