Regardless I knew something was odd with it being in series. Idk why xs would tell me to wire it that way. I got a buddy whom I spoke with before the install he said I should wire it that way too. So where is the confusion coming from?
-
Lol so much for following directions.

So I haven't touched my car yet but I've been thinking.since my batteries are wired in series that would make my system a 24 volt system. My alt would see the front battery fully charged what if I added a voltage regulator so when either battery loses voltage it'll direct the charge to the respective battery. What do you guys think?

Here's the issue with self tapping screws on thin sheet metal
It pulls up the metal it's attached to, lifting up the terminal so you only get contact around the inner ring of your terminal. See below
Black = sheet metal
Gray = self tapping screw
Red = ring terminal
See what happens? Poor contact area, source of resistance and voltage drop. Ideally, you want to ground to something fairly thick, such as a strut tower or frame. But if you need to ground to sheet metal, you should put washers on top of the ring terminal, and on the opposide side of the sheet metal, that way the terminal and metal are sandwitched between the washers, ensuring(insuring? don't kill me grammar Nazis
) that there is no metal deformation and as much contact area as possibleWow awesome thanks man! Well now i got a good game plan for tomorrow. Before i pull out my meter and start shooting im gonna start off my changing my ground. If its still inop then i'll take the readings and see if i notice anything out of the ordinary.
-
OP I understand why you did not want to attempt that but if you have a way to bore out the ring terminal to have a larger sized hole then that's best.
The strut tower is one of the best places for rear grounding and I myself saw over a 1.5volt difference in voltage drop switching my ground to mine.
Its a bit more work but it's all in the pursuit of doing this hobby correctly sir.
I'll give that a shot. Will that mess with the springs or anything taking that bolt off? i have a 2012 car so im very careful when it comes to doing things. its a chrysler at that. should i leave my other ground the way i have it? amps ground to battery then battery ground to strut?
-
ok yea i saw one o those i thought about using it but i chose not to because it was too big for my terminal and i didnt want to cut it

Where are you grounded at right now? Does your car have any strut towers you can ground to?
And self tapping screws don't cut it for car audio grounds just FYI
Pull out your multimeter. Negative probe to chassis ground somewhere on the car.
With both the car on and car off, give me the voltages for:
- Front battery
- Both sides of front fuse
- Both sides of rear fuse
- Rear battery
- Amp
I also need to know: Where is the negative of your amp wired to? The battery or vehicle ground?
my amps negatives go to the second batteries negative. Trying to have them share the same ground
-
Right now the ground is in the rear on the trunk floor. has been sanded and everything. IDK what strut towers are so..... lol. Whats wrong with self taping screws btw? before i had the ground on some bolt sanded somewhere same thing idt its a ground issue. Hopefully tomorrow after work ill try to get you those readings.

It's connected to the top post

My amps won't accept later than 4awg

Dude I'm already embarrassed lol. I took my meter shot all voltage and everything checked good. That's why I'm on here. I'm not brand new to stereos been doing then for years installs and troubleshooting lol funny how I'm getting owned right now by my own system. By crimped the right way I mean with a big *** hydraulic driven crimp tool with 0awg teeth.the only thing I can think of if not a solid connection to my second battery I need to get bigger washers
-
Here is how its connected. Yellow top up front. 0awg attached to positive then after 12inches a fuse holder then it continues then 12in before the xs battery another fuse. Then the postive of the xs batt. Also attached to thepostive of the xs is the power for my two amps. I have 0awg ground I took a dremel sanded it down used a self taping screw and tightened it down. My amp grounds are connected to the neg on my xs batt which is grounded like I just described. Both power wires to my amps are fused as well those are 4awg power. As well as 4awg grounds
-
I checked the ground today. I uses a rockford 0awg power kit. Terminals are aluminum and crimped the right way. My ground is bare metal. Yes its fused right after the first battery and before the second. I'm lost guys I really am. I'm an electrican in the air force on f16s. I don't know what else it could be.

I have two batteries. Up front a new yellow top and a XP750 in the rear. 0awg power and ground connecting them. I now have two amps one is 1000rms and the other 400 rms. my 1000 turns off now at high demand. With engine running i have 14.6 volts up front while 12.5 at the rear on the XP750. The amp min power is 10 volts with the system playing the XP750 drops to 10volts and my amp turns off. Why isnt it matching the voltage at the front battery? What can i do to solve my issue?

HELP-New XS battery low battery volt

FIXED!!!!! First off thanks for yalls help. So here's the fix. The first thing I checked was my connection which was fine. I took apart everything connected to the second battery. I decided to check the washers. On the f16 non conductive washers on terminals cause issues. The washers I had was from a local car shop. I shot the washers with my meter all the washers ranges from 5ohms to 300ohms!!! Wtf!! I had 6 washers totals 3 on the positive and 3 on ground. I replaced the washers with good conductive ones. Works like a champ!14.6 volts. My battery is indeed wired in parallel. I don't know what I was thinking earlier I guess because I was so frustrated I wasn't thinking straight. So moral of the story don't use washers from local shops and always make sure its conductive!
