Stereo Upgrade

8 posts in this topic

Putting together all my supplies for upgrading the stereo in my new to me used Chaparral Sunesta 234.

 I've got 4- 6.5" kicker = 190 watt max; 65RMS @ 4 ohm, 1 - 10" kicker subwoofer = 300 watt; 150 RMS @ 4ohm, Kenwood 5 channel class D 600 watt amplifier = 50 watt x 4 at 4ohm and 300 watt x 1 @ 4 ohm. Kenwood head unit with bluetooth  and replacing remotes at bow, stern and helm with kenwood remotes. 

Speakers and sub have led grill with controller.

Just want to confirm I got the wire size and fuse correct.... I plan on using 4 AWG power and ground directly to the battery from the amp (will be placed near the head unit. 80 amp ANL type fuse - Amplifier draws total of 58 amps based on literature.... Ok to go with 80 or should I find something closer to 60? 

I've seen 16 gauge speaker wire that comes with LED power wires in the same jacket and was thinking of using that. Good idea or better to just use separate wire? 

Is 16 gauge ok to use for the speakers? All no more than 10' from the amp.

Thanks in advance!

Does this boat have a main battery switch?

Where will this be placed? In the bilge/engine bay area?

No advantage to over protect what the amp's potential is, but more importantly, you dont want to over protect the cable's capacity.

Just an FYI, you need 4 conductors just for the RGB LEDs.

Where will this be placed? In the bilge/engine bay area?  Yes, as close as i can get it to the house battery where the positive lead will be connected.  I'll likely mount it on the same backing plate the isolator is mounted on - see pic.

So should I find a 60 amp fuse?

Just an FYI, you need 4 conductors just for the RGB LEDs.  I'm leaning towards running separate 16/2 for the speakers and 20/4 for the LED.

Do you recommend installing an on/off switch to the head unit so it doesn't drain on the battery or is switching the main battery switch to off when I'm done enough?

No need for another switch. Your 1/2/BOTH switch is all thats needed, when all the audio is wired correctly. No need to bypass the switch with the amps or head unit MEM. 

Id suggest a marine breaker over a car audio fuse holder

16ga is fine for speakers. Id suggest 14 min or 12 ga is better for the woofer @ 300W rms. 

60A circuit protection is likely fine. Those 4ga runs would have to be real long. 

You can run as small as 28/4 for the LEDs.

Awesome thanks. Any recommendations on where to buy this stuff?  Was looking at the amp wiring kits but many don’t have exactly what I need so probably better to buy everything separate.

Just my thoughts, I would rather use a breaker than a fuse. I breaker can be reset, but a fuse you would need to replace it. 

Where to buy, many options Defender.com and  tinnedmarinewire.com just for starters.

Do not waist money on an automotive amp install kit. You need to purchase a-la-carte specific to your install. Custom cut to length power cables, terminal ends, solder and heat shrink, RCAs that are long enough but not too long that you have to coil up a ton of slack, etc. There are places you can get everything you need, as well as installation and setup tips. Look for a local marine audio shop first. Even if they dont carry all the brands you are looking at, they may have a comparable model that they are confident in.
