amp cuts off voltage drop

[slvrado28z 10+ year member]

well I just got a new amp and it shuts off and comes back on in a second only when have volume up...the amp is a t2500bdcp @1ohm on 2 ia death rows 15s. I have a red top under the hood and 0gauge power and ground. I have a yellow top laying around, if I do the big 3 and add the yellow top would my amp stop doing this? THANKS

Maybe, what's the stock alt rating?

What are the numbers on your voltage drop???

Goes down to 11 but guess my amp needs at least 12

You're going to cook that amp. You need a bigger alt. More batteries will help protect your amp but will kill your stock alt faster.

how big of alt?

2500w @ 1 ohm I'd say at least 200A, more like 220A-230A would be ideal

still gonna need some reserve even with a ho alt and that amp does way over 2500 at 1 ohm too. probably closer to 3200. i say a xs d3400. and a ho alt.

With the vehicle running all power is drawn from the alternator. If it's large enough to prevent voltage drop his reserve won't matter.
