is this enough electrical?

[bassman619]

So for some reason I had problems with my electrical and now I am thinking there was not sufficient electrical. Wondering if this is enough...

1 mechman 270A alt under hood with SHCA 1/0 OFC Big3 upgrade.

I XS Power D3400r under hood. 1 run of SHCA 1/0 OFC. 

All connections soldered to shca ring terminals

Equipment running is 

2 Memphis 1.1100 amps strapped rated 1100wrms = 2200wrms total 

1 memphis 4.75 amp on highs rated 75wrms x 4 ch=350wrms 

 running 2 v.1 sundown x 12s

All grounds were connected to solid stripped metal surfaces.

 

Battery kept dying. purchased new battery and that one died too.

all remote leads connected to a relay with a 20A fuse

When you say the batteries kept dying do you mean they went below like 12v? That might just be a parasitic drain

or do you mean when you are playing music your batteries can't stay above 12v? In that case check your alternator

 

I've got a very similar situation but a D3400 rear and a D5100R up front with a mechman 240. My voltage is never below 13.7/8 most of daily listening it stays at 14.1/2 

DC 2k and RF P600x4

That mech 270 is more than enough for what you have, explain your situation in detail and there are plenty here that could help.

 

Start with how your battery died and type of batteries? Type of cables and how you crimped them? Grounding point?
