will I need a HO alternator?

[Giovanni15 10+ year member]

ok this is going to be my next setup. brand new Fi Q 12 in a custom ported box tuned to around 32hz. it's going to be powered by a new hifonics brx2000.1d. setting it to 15000rms with a dmm. I drive a saturn vue 2003. 125 amp alt I believe. if I do the big three and add an extra battery to the back, will that be enough or will I have to have a HO alternator? my last system was 2 12 AQs on a fosgate p1000bd and it made my lights dim pretty good but I didn't have the big three or an extra battery. any advice is much appreciated!

No big 3 good agm under the hood and a big agm in back will suffice

how much will those two batts run me? so I cant keep my stock battery up front and just buy one for the back?

do you already have an agm underhood batt?

nope it's stock

You're gonna wanna start with a upgraded agm underhood batt and big 3. Then add a 2nd batt if needed

which one would you recommend? running really low on $$ since I bought the sub amp wire and still have to buy the box.
