Air saws work great in boats, they are easy to get in to tight spots and as long as you have a few different tooth count blades for various materials you can make quick work out of allmost anything.

He doesn't need a capacitor to run 2 PDX amps. Both my PDX's run off 1 battery and never have an issue with power delivery.

EXACTLY......Class D amps.

I suggested adding caps to my system when talking to the Kinetik Tech support. They advised that I did not need caps for my application.

As far as distortion, I have none. I play full volume all the time, if you are in the boat while it is sitting still, it is ear piercing.

I ran 4 separate sets (+ and -) of 4ga., 20' long to the 4 PDX amps. I have had no problems.

Caps may help light dimming issues and other CAR related power issues but in a boat most playing gets done with the engines off and tied up or on the sand. And not having a cap is not going to destroy any equipment. Stick to making the fundamentals rock solid, same size ground as power, upgraded charging wire, good batteries, and not playing after a battery cuts out the system. I find that grouping batteries together lessens the play time and drops the summed voltage. I use 200amp or bigger relays instead of "switchers" to isolate each battery. When one goes low, I flip a switch on the dash and turn to a fresh battery then turn off the low battery. I have been doing car/marine audio for 12+ years and have always had the longest playing boats around. I do not sell caps to people, I sell better wire/altenators/and factory wire upgrades and that makes a HUGE difference. If people want to throw money at a cap thats fine but I feel they are old technology and are not effective enough for the money they cost.

How many batteries do you run? Do you have a inboard charger? What do you mean by using 200 amp relays and not switches?

Curious how you like the alpine marine speakers??? How do they sound???

I dont have the system in my boat yet. That'll be a fall project. A friend has the same exact system in the same boat and it sounds better than anything I have ever heard IMO. I know there are better. But I know I will be happy.

I have 2 SRM-29 Interstate batteries for the stereo only, and 1 SRM-24 for cranking and boat acc. The 200amp relays are basically similar to a starter relay, it allows you to use a rocker switch on the dash instead of opening the hatch or seat cushion to manually flip a switcher, much more convenient then the switcher and I think they flow more current (never tested that theory). I can email you a photo of a setup like that in a customers MasterCraft.

Yes if you could send a picture that would be great.

I currently have 2 batteries and planned on adding 2 SRM-29 Interstate batteries.

Do you have a on board charger or do you rely on the alternator to charge them?

On board 3-bank 40amp charger, but I will be getting my altenator re-spun for some more juice in the off season.

If you want to see that relay setup I forgot there is a photo on my website in the gallery under the Master Craft XSTAR.
