Too much watts for my car??

[merritt509 10+ year member]

hey all, i have a 2004 subaru wrx. My question is simple. I want to know if my car can handle what i want to throw at it. For now, i have the big three upgrade in 4 gauge wire. im running a Kicker amp that brings 425 W RMS to my two 12" type Rs (425 a piece). also, i have a soundstream 4 channel amp running my 4 speakers at 100 W RMS/speaker. for the subs, I have a 20 Farad cap (i know, overkill), and for the speaker amp im running a 1/2 farad cap. my plan is to run another amp with 400 W RMS going to 4 more speakers (100 W RMS a piece). will this burden my electrical system too much? i dont get dimming right now as it is. my headunit is a pioneer 3200DVD. i believe my alt is an ~80 amp. any suggestions? This isnt a pressing issue, i just want to expand my highs and mids. for the new amp, i will be getting another 1/2 cap. i know caps dont help much, but just saying. thanks guys

i lost track here, but normally cars can handel 1000wrms with just the big 3

ok, essentially, what i want to do is have 2 amps running 8 speakers @ 100w rms per speaker, plus have my kicker amp running my two alpines at 425w rms per sub. right now i have one amp running 4 speakers and the kicker running the subs, im wondering if i add the second amp for the last 4 speakers if it would be too much for the electrical system.

so your running 1650 on stock alt? Thats too much. especially an 80 amp alt

anything i can do without tampering with a new h.o. alt?

i would suggest a new alt, even something like 110 alt or anything and possible a new battery under the hood and a second battery
