I have an 08 sierra with dual batts under hood. With new amp (sundown scv2000) im getting voltage drop especially turned up at idle, sitting still at stop light. Both batts under hood are Duracell 65ah each wirred in parrel. With a mechman ho 270.
Im not sure if i should replace those with xs power d3400s or add a xp3000 to the rear. Which do yo reccomend and why? Thanks guys!
