Upgrading exile stereo in 2008 ski supreme v212

Hey everyone,

Recently purchased a 2008 Ski Supreme V212 last summer and was hoping to upgrade the stereo system before spring/summer.

Boat: 2008 SKi Supreme V212 SKY Package
5.7L Mercruiser Black Scorpion (75hrs logged so far)

The current system is as follows:

H/U = Sony Marine CDX-H9051P
Cabin Speakers= 6 Sony XS-GT1625A (40W RMS)
Subwoofer= 10" JL 10W0v2-4 (300W RMS) (Under port locker in ported box)
Tower Speakers= 1 pair SXT65Q surf speakers (125W RMS+)

Amp= Sony Marine XM-604M 4 channel (Currently being used to run tower speakers on front 2 channels and Bridged off the back to the JL Sub)

Unit came with a 2 Starting batteries group(24)
Using a Noco 90A isolator (no perko switch being used just isolator)


The new equipment I got is as follows:

1 Exile SM-400.4 amp to run tower speakers in a bridged configuration
1 Exile SM-250.1 to run the JL 10" Subwoofer
1 Exile ZLD
Tsunami Distro block
RCA Cables from ZLD to amps
Relay for sending power to amps on remote trigger
Autosound 2000 cd 104 (for tuning)


The current Sony Marine amp will now be used to power the 6 Sony cabin speakers giving them much more power than the head unit was outputting

Most of the time is spent surfing, wakeboarding. On the move, boat running!
Boat comes home every night for battery top ups on trickle charger and garage protection


The important things to consider here is what battery configuration should I be looking to setup to power the system?

*** Looking for input on battery upgrades (DEEP CYCLE OBVIOUSLY)
*** Battery bank hooked to alternator? not hooked to alternator?
*** How to Not cook my stock alternator without upgrading alternator
*** Installation recommendations do's and donts
*** Amp rack mounting ideas
*** Input on the equipment being used


Really look forward to hearing some comments or concerns

Please ask more questions if I have not provided important info

Cheers Everyone
