Need advice on upgrading electrical system

[maxmil982]

I'm running a 4-channel precision power 900.1 amp... gonna push front components (kicker kss65 125 rms each), and and some decent coax in the rear doors amped probably around 75 rms each as well...also gonna run an orion hcca 1500 and use it on a sundown sa 750rms 12" gonna push about 1000rms clean to it...so total about 1400rms

I have a 2003 Acura tl with stock amp and battery. What upgrades do I ...NEED...to do to have this running smooth. Just want to have it done right without spending more money that is necessary, but also don't want to skimp out and strain the system

Thanks in advance

Oh lol p.s. to any noobs like, pls me find out what your electrical system can handle before installing things. I started with JUST the pp900 amp JUST running the front components 125 rms apiece and my electrical system went haywire....I think my alternator or battery was either messed up prior or was operating just enough to operate the basic car functions. Cuz soon after I installed the front components only all kinds of fuses blew...lights, blinkers, cooling fan had to be replaced shortly after, ac blower failed (connection melted), cig lighter wouldnt charge phone if stereo was on...you name it...electrical ended up being the most important overlooked first step...

- invest in a volt meter that will run directly from your sub amp to the front dash.

- put in all your gear first and get it going/set properly/push it. Then you can see how your voltages drop. If they are dipping into 11s, you'll need the big 3 upgrade first of all. If its still dipping low, best course of action would be an alternator upgrade, a new one costs 450+, an alternator rebuild/beef up would be around 150 give or take.

- Other option (after big 3 upgrade) if your voltages are low and you are tight on cash, Get a secondary battery. This should help your voltage keep above 12.6/12.8. Its a band aid solution but it'll hold up for a few years just fine.

- If you have everything playing and you are keeping above 12.6/12.8 stock then you have no need to upgrade to be honest.

Thank for the advice

This ppi900.4 is rated 145rms x 4 but at 14.4v

And 100 rms x 4 at 12v is it safe to say I need about 13.5 volts to get that 125rms....I know this might be splitting hairs just wanna know will that extra volt give me louder sound to the comps...just want to get the most out of them since they're not super loud to begin with

Not gonna feel it at all. Wont matter unless you are dipping to low 12s high 11s.
