Do I need an electrical upgrade??

[Juulian]

I have an 02 Chevy Tahoe and have had the same system since I was 15. A 50 dollar power Acoustik PL-51b 300w 4CH head unit, old hand me down 600w 2 channel amp on the subs and old hand me down 600w 4 channel amp on the doors, Walmart coaxial door speakers, and 200 dollar pawn shop 150w rms kicker comp 12’s. I have some new deaf bonce apocalypse M61SE pro 6.5 midranges on the way for the doors and just bought a taramps smart5bass amp and 2 2500w rms sundown xv3 12’s in a tru spec box.

With the new subs, new sub amp, new door speakers, same 600w 4CH amp, and same power acoustik head unit, do I need to upgrade my alternator or get a power cell (I know nothing about extra batteries/power cells) or do a big 3 kit?? What upgrades are necessary if there are any???

You will definitely need upgrades. The big 3 and a high output alternator and/or a lithium battery.

A definite maybe. The Taramps pulls 230A at full tilt.
Any idea what your other amp draws?

What are your listening needs?
Before you spend the money on an alternator, hook it all up and listen like you normally would, and check your current draw.

If you need an alternator, doing one after a full install is no different than during.

I looked up the manual and it says the current consumption is 35.0A at continuous power, 4ohm.

My listening needs are to be as loud as possible without causing damage to any part of my setup. I’m not going to ride around with the volume up all the time, but I’m about to move back to college for my sophomore year and with the new sundowns and door speakers I want to be the loudest one on campus lol.

I’m gonna take your advice and install the new speakers, subs, and amp then see if my lights are dimming, voltage dropping, etc.

Good idea.
Plan for the big picture. Exceeding you alternator's capability once in a while is fine.
Once you got the point where your battery is no longer being charged, you know the next step.

Skip the Alt upgrade, get yourself a GloweVoltage series 1 or 2, whichever is available on your stock alt, and be done.

Glowe Voltage - Series 2

Double the power. Half the cost. The future is now.

This is my go-to on draw, for most people - daily drivers.

Absolutely need electrical upgrades. I ran a 320 amp alternator and 40ah of LTO lithium on that same amp.

Here is a 370 amp alternator and 54ah sodium lithium prebuilt battery.

I would add, OFC big-3 too, adequate cabling for all, then the GV, should be fine. Most are never going to come close to using max potential, but if you do, this will still cover it.

What size and brand power wire you're running?

Update: I took my truck to 3 different audio shops to get their opinion and a quote for the install. All 3 shops said I need to run an auxiliary AGM battery to a thicker wiring kit, big 3, and an isolator.

One shop said for the install and the extra things I need (AGM battery, wiring kit, and isolator) it’d be around $1012 said and done,

When I asked him for a break down of that price here’s what he said

Krank it up AGM cell - $250
Sky high car audio 1/0 ofc wiring kit - $229
Nemesis audio isolator - $99
Labor and taxes - remaining $450

Lithium and sodium batteries cheap enough now that running agm in a system that size doesn’t make sense.
Also, be security conscious. Having the loudest vehicle at a college is a good way to get your stuff jacked.

Telling you right now a single AGM battery with no HO alternator is NOT going to run a Taramps 5k. Takes power to make power.

Ok, so HO alternator AND AGM battery or just the alternator with the big 3 will do?

Big 3 is a must have no matter what.
At least a 300+ amp alternator and AGM in the front and back.

Again I ran mine on a 320 amp alternator and a 40ah LTO lithium battery in the back.

I have not run one of those amps.
If it pulls 230 at full boogie, why did you need 370 to stay alive?
Or did you go big since you had to replace it to eclipse the 230A anyway?
