Will the electrical system be able to support this?

[crreed55 10+ year member]

I have a 2001 Honda Odyssey.

Planned Electrical Mods:

- Aftermarket HO Alternator (200 Amp, stock is 130 amp)

- Replace stock battery with Optima 8040-218 D35 YellowTop Starting & Deep Cycle Battery

- Big Three Upgrade with 0/2 gauge wire

What the electrical system will be supporting:

- Boss CX600 Amp (75RMSx4 channels, fuse rating: 20A x 2)

- two Kenwood eXcelons (80RMS each)

- two Boston Acoustics S45's (35RMS each)

- RE Audio XTX-3000.1 Mono Amp (1400 watts RMS, Fuse Rating: 35A x 4)

Will the upgraded electrical system be able to support a system like that?

If it will, will it be able to support a second RE 18" inch sub and a second mono amp (or one amp about double the power)?

Better look into unplugging/disabling the ELD if that model has it or none of that will matter.

You will need more battery power than just one Optima to properly support your needs.

Some of the Honda CS130D (yes, Honda used CS130D's for a couple years in the V-6) builders only swap the stator, they do nothing for the rectifier or the rotor to improve your power curve. This leaves you with the same or less output at low speeds and will cause your voltage to drop without the engine speed up.

Provided that the HO alternator is a quality unit I would recommend replacing your underhood battery with the largest AGM that will fit. I prefer XS Power, but there are other brands.
