Stereo Upgrade

[Dex202]

Hey Guys,
Be careful how much power you put in your boats Added two 12" subs in the front compartment along with two more amps. That makes a total of three amps mounted in the rod-locker, four mid-range 6 1/2" speakers, CD player mounted under the console, and the two subs. Played the stereo for about 1/2 hour and the cranking battery was dead. Had to jump off one of the trolling batts.
Plus these subs are shaking EVERYTHING. Had to install a cap from the cranking battery. Hopefully the battery won't drain as fast.

Use a big Deep Cycle as your cranking battery. Optima Yellow Top

Using a cap probably will not help your battery last much longer. All a cap does is provide a burst of energy for your sub amp when it needs the extra power, it also helps to provide a more consistent power instead of spikes and valleys of voltage going to your amp. The cap is constantly being recharged from your battery.

Cak,
Your right. The cap didn't help at all, but improved the "Snap" of the subs. I'll have to try a Opti batt. Just hate spending that much on a cranking batt. I've just purchased two Opti blue tops this winter for the trolling motor (ouch)
