Yellowtop 51R enough for ~1500RMS?

[nstillmatic 10+ year member]

Hi, I just ordered $200 worth of knuconceptz stuff to do the Big 3 and upgrade the wire to my amps as well as a HO 165 amp alternator. I can't afford to jump on a rear HC1800 just yet so I'm wondering if my single yellowtop 51R would be sufficient (at least for the time being) to run my system?

I'm going to be running a Sundown SAX-1200D and SAX-100.4D. Also, if a battery doesn't have enough to power them both could this cause any damage to amps or wires, etc.?

the amps could blow due to voltage drop but i believe with the upgrades you made youll be in the safe zone, if your super scared turn down the gains for now or you can monitor your voltage if it drops too low for the amps (check their operating voltages) you can kill them. If you stay good with barely any drop on big lows then turn your gain up a lil then watch the voltage again, if your still good then adjust again, do that until your at a safe gain level (dont turn it all the way to the right or 100%...) and wires will only be damaged if you draw too much through them if you didnt order 0awg then id start looking into it but youll be good on 4awg if thats what you got.

it should work

Is this here enough to watch the voltage? Since I ordered one of those with the wires.

Oh yeah, I also have a regular wet battery. Would it be safe to just put that under the hood and move my yellowtop to the rear temporarily? I heard it's bad to mix those with drycells, and I don't have an isolator.

450 CCA and 38 AH is not very much, I hope the alt puts out what it should, dont play with the vehicle off

well if you needed the dist block then thats fine but u couldve just use a DMM (digital multi-meter), and its not gona be significant if the yellow tops in the front or back as for adding the other batt im not sure, i do know that adding a bad batt will hurt not help your system.
