lto

Hello all, Can I put LTO Yinlong batteries as second bank in the trunk to power up 3k amplifier... I had 90A alt and 80Ah batt ... But when bass hits I drop from 14v to 12.9... ive put 120Ah and had drop to 13.2v ... So few weeks ago I bought 180A alt so now my drop is to 13.3/4 ... I guess...
