[QUOTE="SFCMcCarty, post: 8680471, member: 677652"] I have a 2009 Subaru Impreza Outback Sport; I upgraded to a 100 amp alternator, did the big 3 upgrade(4 gauge), added a second battery 2x OEM replacement (fused 4 gauge battery to battery), 1/0 gauge from second battery fused to 50 farad cap distributed to 2x 4 gauge one to Skar RP1500.1 at 1 ohm to 2x 12" SDR Subs and a Kicker 4 channel (Max output 600 watts) to JBL Front components and rear 2-way JBLs. Sounds awesome but I know I can get more from my subs but, my cap shows an immediate voltage drop when the subs hit (Turned up about 1/2 way.) Result: Kicker amp goes to protect and then eventually turns back on. Is this a ground problem (Multimeter appears to to read voltage but, dont know if anything is grounded properly(new to the multimeter game))? Or could this be an Alternator problem? [/QUOTE]
