Is 250 enough for my set up?

[WhiteMan_FTS]

Hi everybody. I listen to rap with low bass, and my head unit is at max(before it sounds like crap) at all times. I drive probably 3-4 hours a day.

Previously I had a 94 towncar and the set up was

2 Alpine type r 12"s at 1 ohm

Hifonics 1800 at 1 ohm

0 gauge power and ground

Factory 130 amp alt and walmart battery

At night time my voltage meter would sometimes drop town to below 12.5 and I know that that is not enough.

I now have a 95 towncar.

My set up is going to be

4 Alpine type r 12"s

2 hifonics 2400 amps

0 gauge big 3 upgrade

0 Gauge power and ground wired to rear battery

250 amp alternator (Will this be enough?)

My questions are:

Is 1 250 Amp alternator enough?

What batteries would you recommend for under the hood and in the trunk? Optima yellow tops?

Please keep in mind I am trying to keep this as affordable as possible.

I would seriously consider throwing an XS Power D3100 wherever you can get it to fit, and then you should be good.

I would add two G31 batteries to the back. More alt is never a bad thing. Those amps are power hungry.
