[QUOTE="Doxquzme, post: 8875527, member: 689267"] For the noise, check the source and signal transfer, amp grounds etc, could be the head unit is picking up noise. Could be that you have RCA's or speaker wires running parallel with power and ground. As for a second battery for a 3000 watt system you have lots of options. If your battery is in the engine compartment up front and your amp is in the rear, I would wire the 2nd batter using 1/0 gauge OFC welding/power and ground cables from the front to rear and I would also run a parallel ground in the rear to chassis/frame. Here is some info on parallel grounding. It is essentially +/- cables from battery to battery then grounding again at the second battery. [URL]https://www.bestcaraudio.com/car-audio-myths-you-cant-ground-a-car-audio-amplifier-to-the-battery/[/URL] If your battery is in the rear near the amp, simply upgrading the battery to a larger AGM battery might be enough. If you decide to run a 2nd battery, you are not running a lot of power for the alternator that you have upgraded to and that leaves open a lot of options. The simplest and most cost effective being that you;re in Bulgaria would be a LifePo4 lithium battery with at least a 100A BMS.

Another option is a super cap type item or a small AGM: AGM [URL unfurl="true"]https://www.amazon.com/dp/B0089NRB70/?tag=caraudiocom-20[/URL] Very good option: [URL unfurl="true"]https://www.amazon.com/dp/B0BLCZL8LK/?tag=caraudiocom-20[/URL] [/QUOTE]
