Wire the 2nd house battery in parallel (+ to +/- to -) with the existing house battery. All loads, except the auto bilge B+, need to be wired to the C post of the switch.

Youve probably discovered the answer by now, but i'll share for those fallowing along. The "3528" and "5050" denote the size of the LED pod and does not dictate the number of LED pods per foot. A...

I think your real world stereo current draw will be about 60% of what you think it will be. This will fluctuate with volume levels and music type, but on average, I think its going to be less then...

Trayson,

What amperage alt do you currently have? 2nd, i mean no disrespect, but alts from DB are considered price-point upgrades as far as marine alternators go. They basically take a stock...

First test the static voltage of both batteries, then test the alternator output. If those readings are good, then do a voltage-drop test across the posts of the switch. If the switch is bad or...

Get a bluetooth and plug it in that AUX port, then stream your music. Not the best sound quality, but convenient.

Steven,

Yes, you would bridge a full-range speaker just the same as a sub. You will connect the speaker + to one chnl's + and the speaker - to the paired chnl's - terminal. 200W rms is a lot for...

Since a typical stereo amp only has a single gain control for the two chnls and a 4 chnl, which is basically 2 stereo amps in a single chassis, it only has a gain control for chnls 1/2 and one for...

Definitely run all 4 chnls on Hi-pass, which will be controlled via 2 switches. This will cut out those lower notes that those speakers will not want to play anyway. Yes, DVOM = digi volt/ohm meter. ...

yes, four 4 ohm speakers wired in parallel would be a 1 ohm load. Bridging that would be placing a .5 ohm load on each chnl. Not only a rare few mono amp will handle a .5 ohm load.

Regardless of...

When you bridge an amp, you are using 2 chnls to gain their combined output. Each chnl is seeing half of the bridged load. In your case, you are bridging a 4 ohm load comprised of four 4 ohm speakers...

Just an FYI, your series/parallel with 4 ohm bridged load results in each amp chnl "seeing" a 2ohm load. Same is if a pair of speakers were wired in parallel on each chnl. 4 chnls running @ 2 ohm is...

Steven,

Your 200W in-boats are probably 200W peak. I would look for a 4 chnl class-D amp that will deliver in the range of 75-100W rms x 4 @ 4 ohm.

Or, look for a 5 chnl that will deliver about...

Dave,

Since the noise goes away when the RCA cables are disconnected from the amps, this indicates that the noise is coming in on the signal line and is upstream of the amps. They are simply...

The remote turn-on from the head-unit may have gone to the bad amp first, then daisy-chained to the next. If all the speakers were functioning before the amp was removed, then its either not bad or...

As Mcdye stated, the WS-420 would not have been a factory SC option, but could have been installed by the dealer/stereo shop or by the previous owner. If it was done in a very custom manor, you would...

I can tell you without a doubt that its a night and day difference with that sub in a 1c/ft enclosure. Now, granted its not the power handling of a W3, but its a very musical sub and deserves an...

The Clarion Marine units typically have 3 RCA outputs: Front with gray leads, rear with black leads and non-fade with purple leads. The purple non-fade is adjustable, so if the sub is by chance...

Building a ported box can increase a subs output, but I need to run the specs on that one to see if its better suited one way or the other or if it falls middle of the road. Im betting is the kicker...

Randy,

First thing I would suggest, if it hasnt been already done, is investigate the amp settings. Swapping the sub could very well yield the same poor results if the amp settings are not ideal....

Those pumps have a about a 15A continuous and 20A spike. Most boats use a Carling Tech Contura rocker body. They have a 20A rating, so they will handle the current of 1 pump. They need to be a 6-pin...

If you are using it as a reversible ballast pump, you will need a dedicated 20W DPDT rocker switch for each pump. Or, a complicated relay setup is needed in order to reverse the flow of a DC motor...

So what about a machine screw through the grill of the XS-650 with a locknut threaded on securing that holding fixture in the same manor as the PG does with a through-bolt threaded into the speaker...

You will need a new amp to drive them.

The Syn-4 will drive all chnls with a single set of RCA cables connected to "Front" by moving the switch to "2-Chnl" So FRONT to one Syn-4 driving the in-boats, REAR to 2nd Syn-4 driving Rev-10's and...
