Those LTO lithium don't like high voltage and they are meant for discharge bursts, not reserve capacity. Get a good AGM starter battery, they are meant to hold more reserve capacity than the lithium you have. Get one of these.


Our stock batteries suck for car audio. That battery will help with the voltage drop. Your not running much power, you don't need to bypass your voltage regulator. You need to keep your voltage steady. When you turn the lights on it will jump to 14.4.

An other thing to consider is the type of wire you used. If you used CCA that will be your problem. It's best to always use OFC wire.
okay thank you i’ll get that battery and see if it improves my voltage. Also i have a run of cca but plan on upgrading it to OFC. thanks i’ll let you know how it goes after.

Just installed d4800 yesterday. Now i have the lto battery from d4s. 290 amp alternator with big 3 OFC 0 gauge. and a D4800 i am experiencing low voltage still but it shoots back up form 10.5 to 12.5 on bass drops. but it’s prob because i have only
one run of 0 gauge to the back but its SKAR 0 gauge CCA lol i am gonna replace that next with sky high audio 0 gauge OFC 2 runs and hope it fixs it. I only own the skar 0 gauge CCA because i didn’t know much about car audio at the time of purchase lol

Yea it's that wire. Those thing will eventually deteriorate and fall apart. change that and you'll be good

Do you have to run ofc wire for the ground

Im new here to this page i have a 18 honda accord w/ 3p airlift system im upgrading my sound system to 2 12s L7 Q class total of 1800 RMS w/ a XCA1800.1 kicker amp and a 250 RMS RockfordF.. I recently got a XS4800 battery that is going on the trunk that is going to be powering The amps.. So this is how im setting it up bcuz im barely getting started and not to mention its my first time installing a system. Front stock battery is getting the BIG 3 but does the ground have to be OFC wire?? From Front battery i have 1/0 OFC Skar audio wire w/ a 300A going to the Rear Battery with another 300A b4 the Positive terminals and then from there i have a fuse dual block being fed w/ 1/0 OFC kicker wire then i have a 200A fuse going to the xca1800.1 w/ 1/0 OFC kicker wire. That how far i got. My Q is do i have to Run OFC wire for ground?? ALso should i run another 1/0 wire from the front battery ground to the rear battery ground?? IM sure its better ti do that but do i have to also if i do have to can i run 2 gauge wire instead of 1/0 wire. Plz help!! im on hold due to this rain soo i got some time to get supplies if i have to??

Yes... always use OFC. CCA is junk and is not worth wasting your time on. You do not have to run the ground from the front to the rear. Find a good ground spot in the back and you should be good. I'd also suggest you don't pair your stock front battery with an AGM in the rear. Don't mix battery chemistry it won't end well. Put the XS-POWER in the front. The stock Honda batteries suck, really bad.

You not running much power so you may be able to get away with just replacing the front battery. If not I'd suggest a lithum bank in the back. Much smaller, less weight, more power. I run 2 XS-POWER titan8 S5's in my trunk and I comfortably run over 6k with the stock alternator.
