    Earmark Marine

    I just checked their site a moment ago, it is up and running, and it appears to be a brand new site design. It's actually very nice and more smart phone friendly. So perhaps there's is a temporary issue with the changes? I don't know much about internet/computers. But try refreshing the same...

    Charger Guy Retiring <He is now Island Jay!>

    Charger Guy....good success to you whatever that venture may be. And as a side note, I'm not too proud to receive and try out various free clothing samples. Just sayin'.

    Maybe not. But I still bestow upon thee full 'bull dozer' status.

    Subwoofer(s)

    That's certainly one approach....the bull dozer effect....with two 12s and 2800 watts. Let's not let little inconveniences like fiberglass walls and seating cushions get in the way. Power on through it!!!

    Subwoofer(s)

    If you are going to run no larger than a 10-inch subwoofer, and no more than 250 watts to the subwoofer, then the best route to go is with an infinite baffle JL Audio sub, exactly like the robert843 example. So load up on a Marion's pizza for energy and get to cuttin'.

    Wet Sounds or Roswell?

    Actually the Wetsounds Icon8 is a direct-radiating coaxial using a conventional 1" dome tweeter. But not an HLCD. In the same size the Wetsounds Rev8 is an HLCD.

    Wet Sounds or Roswell?

    It's hard to make sense of the dealer comments because the authorized on-line dealers list Wetsounds at M.A.P. For example, Crutchfield has never been known for their deep discounts. So the profit should be unchanged. However, if the dealer doesn't stock product they may be at a disadvantage...

    Wetsounds EQ

    The Wetsounds EQ definitely includes all the required hardware for an under-dash mount. Odin w/ Earmark Marine is a good Wetsounds source and has illustrations & instructions for a variety of non-standard mounting methods. Odin also fabricates anything (such as a custom trim plate or mounting...

    Amplifier wattage question

    The 300 watt 2-ohm rated power will be divided equally by the two identical 4-ohm woofers, so 150 watts each. Keep in mind that most amplifiers are rated with a 14.4 volt supply, which isn't realistic in your boat. With a 12.6 volt supply that 300 watt rating may be a more realistic 225 watts...

    Easy way to add extra bass

    A subwoofer, to a degree, is a tuned resonator in itself. It is very application-specific. You are targeting a final loaded/system 'Qtc' of let's say around .85. An IB subwoofer begins with an unloaded 'Qts' of about that number and maintains that number once properly installed (in this case for...

    Easy way to add extra bass

    It all depends on your SQ tolerance. I wouldn't do this. But others will because it will net them plus bass. Ever heard of a bass-reflex enclosure. Of course you have. One of the critical principles in the woofer and port working somewhat in phase when combining the front/rear output, is the...

    Easy way to add extra bass

    A 10-inch subwoofer in one form will be similar to a 10-inch subwoofer in another form. With an IB direct-radiating subwoofer you have zero loss and zero filtering of the natural response. With a concealed (mounted inside a compartment) air-suspension (sm. sealed box) subwoofer, even with an...

    Uh Oh...No power at the HU

    What? You want me to give Mel the business some more?

    Uh Oh...No power at the HU

    DARN IT!!! The solution came to me five minutes after you shipped it off.

    Scarab 215 - Powering amp from batter switch

    Paul, Do not confuse a dual circuit switch (4 posts) with a conventional dual battery switch (3 posts). With a conventional dual battery switch, which you likely have, simply wire the amplifier breaker to the switch 'common' post. Yes, the ground remains on the battery.

    what battery charger/maintainer do I need ?

    Scott, If your lawnmower battery dies in a week then it needs replacement now. If you have a single battery then you need a single bank charger. If adding a second battery/bank is in your future for any reason then buy a 2-bank charger. The amperage capacity of the charger you choose depends...

    How to calculate battery life with a big stereo?

    It's a hopelessly complex calculation and there is no accurate calculator. Music is AC in nature so the draw is only a fraction of the DC calculation. Amplifier efficiency will differ based on the Class and the impedance load channel by channel. The circumstantial fluctuations can go on and on...

    Great! I would say you are all finished except for the hard work.

    final amp advice

    Not a 'spacer' ring but a birch 'baffle' ring which is intended to give you a more rigid baffle surface. This is a valid addition and a performance improvement for a 10-inch IB subwoofer mounted in a thin fiberglass wall. How it's installed also makes a difference. So I would definitely heed...

    Some subs not speed...

    This is something that Earmark Marine has been doing for a long time and they do it a little different. Odin recommends mounting the enclosure in advance and independently of the sub driver. So when you go to mount the sub driver, the enclosure is already fully mounted and fully sealed against...
