Cs25 amp location
Posted: Sat Jan 22, 2022 7:47 am
Can anyone help me locate the amp location on a 2017 cs25? FIL’s boat and we’re trying to dissect the stereo package.
That’s my assumption too. Perhaps his does run off the HU amp.Lifelongbtr wrote: Sat Jan 22, 2022 5:29 pm R3-7 is located right in front of helm, accessed under the seat in the bow. If I were to guess it’d be in the same spot.
I’m not sure if the base audio package has an external amp or not. How many speakers, and it sounds like no sub? What is the brand of the head unit?fischelr01 wrote: Sun Jan 23, 2022 7:04 amThat’s my assumption too.

Time to start chasing wire.
He just bought a sub and amp. Was cobalt still running 8 gauge to the amp location in 2017? I found the factory wiring in my 2008, not sure if they were doing the same 9 years later

My boat everything runs off external amps, and I think that’s the case with premium or platinum sound.
They make 6ch HU’s now, assuming they did a few years ago as well. Another way to check would be on the HU itself, in settings check for preamp settings and they may be off or try to adjust and see if there’s any difference. If you can get to the back, probably the easiest way would be to look for the amp out wiring vs speaker wiring. I doubt they’d pre-wire amps if it wasn’t chosen as an option.fischelr01 wrote: Sun Jan 23, 2022 6:33 pmLifelongbtr wrote: Sun Jan 23, 2022 4:19 pmI’m not sure if the base audio package has an external amp or not.

I believe it’s the kicker HU. 6 JL coaxials. I know there’s no amp forward the helm.
I also didn’t see a “stereo” fuse with the bildge and helm main fuses. Makes me think the original owner didn’t buy an upgraded package.
I agree. Once I have a chance to get in there and dig around for a few minutes, I'll be able to tell.Lifelongbtr wrote: Sun Jan 23, 2022 8:22 pmThey make 6ch HU’s now, assuming they did a few years ago as well.

In any case I’d think you buy new amp(s) and set it up right. My boat is two 5 ch amps, 4+sub. Total 8 speakers, 2 subs with the two amps, few separates mixed in.
If Roswell was the supplier for platinum audio at the time, contact them, you may be able buy the amps, speakers, etc. They “tune” the amps for the boat, which sounds cool, not sure how much difference it makes other than being able to crank it and not worry about too much/little power for the setup.
A 300w amp with a 15-16' run would produce minimal resistance with 8 gauge wire. At this point, we're only adding a single sub amp.

On the SC series, we dropped it in adjacent to the head door on the port side. The port side “wall” just above the floor. I’ll get you a picture when I’m with them today.stifflkd wrote: Tue Apr 12, 2022 4:23 pm I have an R5 and the HU is in the same general area. Installing the amp on the forward panel in that compartment makes the instal simple and your power run fairly short to the back end of the breaker panel. Question; where are you installing the subs. That is next on the agenda but don't want to have a oh shit moment after cutting the holes.
