I have a 1500 skv2 Skar audio amp pushing two 1200 watt RMS 12s on a 130 amp factory alternator with 3 month old die hard platinum battery. I'm not experiencing and dimming or high voltage loss but wanted to add a second battery just for mental comfort. Lol... Also to be sure my power supply is covered. Have the big 3 done also. I don't wanna wait a month for secondary battery to be delivered. I want to go to my local auto parts store n pick one up. Not sure what to get. Am I good as long as it's another AGM battery? Was thinking die hard gold. Using 1awg for power wire btw. Hope to hear from someone quick. Wanna do this today. Thanks to whoever is reading all this!

 

Yep. Another AGM would be great.

 

Thanks for replying. I'm going to go with Die hard gold.
