2010 f250 diesel electrical system question

[joep1231026 10+ year member]

2010 f250 6.4L powerstroke 4x4 stock:

dual batts : 750-CCA/78-amp

one alternator: 135 amp

2/0 cable from each battery to chassis

1/0 kolossus fleks from batt to amp, and 1/0 ground cable from amp to chassis

8 gauge kolossus fleks speaker wires

not sure what size cable from chassis ground to engine block (cant find it)

looks like 4g from alt. to batt., could be 2 gauge?

voltage drops are high (havent measured yet) and lights dim on a beat.

12" solo X on a sundown SAZ-3000D

could any of this have contributed to a burnt coil?

is is necessary to do the big 3? (2/0 seems large enough to me?)

what will big 3 + new alternator provide (performance-wise)

i'm worried im only getting about 1000W or so to the sub... (once again, havent measured yet)

please give any and all advice... thanks!!!!//content.invisioncic.com/y282845/emoticons/verymad.gif.3f39c5c2fd57527b671fad3efdfac756.gif//content.invisioncic.com/y282845/emoticons/furious.gif.fc81ca146dbff91fede3ed290dbc4f4c.gif//content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif//content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif

What ohm is the amp wired to?

why would you only want to get 1000 watts to a solo x? also why did you buy a 3000+ watt amp if you only wanted 1000 watts?

He is worried that is ALL that he is getting and wondering how drastic the change will be if he upgrades his electrical.

Do the big 3 to what is not already done. And if you want you can add more to the 2/0 as well. Overkill ftw

Get a bigger alternator and see how she performs then

thanks, its a d2 wired to 1 ohm

and also, what will be the total current coming out of the 2nd batt if the engine is running (ideally)? and is this governed by the capability of the alternator (135A)?

sorry but i have a million questions. thanks to everybody.

That amp is too much for your alt and regular batteries at 1 ohm. Do the Big 3 and upgrade the alt first. You may still need to add a battery or upgrade the existing ones.

The current coming out will only be equal to what is being drawn by the accessories that are being used. When your load overcomes the amount of current available, your voltage will begin to drop drastically. A 135A alt and two regular batteries are not enough to maintain voltage for an amp capable of drawing ~300A.

750CCA is normal lulz

Yep, it is for a vehicle WITHOUT a 3000w amplifier. Good job noob.

so on a voltage drop, the current increases like crazy, but the total power absorbed by the sub stays the same (no?). So a spike in current would not necessarily burn a voice coil, correct? seems like that would do more damage to the amp rather than sub... i guess i will have to do big 3 and then see how it goes...

thats some sucky electrical. my 97 jeep cherokee never dimmed on stock electrical.

The total power will decrease as the voltage decreases because you have insufficient current also, Ohms Law: Power = voltage x current. True, the voltage drop is worse on the amp. But it does cause the amp to distort, which will lead to speaker damage.
