12 volt for stereo amp

I would like to add an amp and subwoofer and was wondering where to get a good supply of 12 volts. I see there is 2 selenoids under the hood with a hot side. Anybody use these for power?

I would think the best source of 12v would be connecting to the front's batteries. That's where I hooked up to my powered sub.

If you are going to use the amp while parked I would recommend tapping off the house battery rather than the chassis battery. Running an amp can drain a battery and you sure don't want to drain your engine starting battery.

There may be a solenoid/relay on your firewall which connects to both batteries. When the engine is running it will connect the house battery to the engine's charging system. Easy place to tap for power. Just pick the side that runs to the house battery.

No, havent used them for anything custom.

My Entegra has the same 2 breakers. The driver side is used by the power steps. The passenger side is unused. I "think" the passenger side is for levelers, which I dont have.

The passenger side would be a good connection if yours is unused as mine, if its powered of course; and if the power is from your battery of choice.

Understand what actually powers that dash radio is spaghetti wiring. Its a combination of camper and cab battery power.

I pulled power off one of the solenoids on the firewall, the lug I pulled from has a cable that runs down to the battery. I went from there to a Bluesea fuse panel mounted on the drivers kick panel for any accessory power I need.

You will need to route it from two places... Power for the AMP and then you will need the signal wire from your stereo unit to switch it on/off when the unit is on. On our Seneca, I tied into the Cigar lighter circuit which is 20A instead of splicing off the Radio power which is only 6.7A.

There are automobile amps now that have current sensors and automatically turn on when milli-amp current is sensed thru the audio circuits. Ask me how I know.

will the Seneca be able to power that AMP with a 20A circuit that is already shared with other loads?

It's the Z-150.2 right? set up at 1x550w-bridged? no clipping?
