    There are many tower speakers with the wires concealed within the collar, such as Wetsounds or HollowPoint. It won't help in this application if you mount to the flat plate. In any case, new...

    Based on past experiences I am concerned about a fully potted charger when used with a heavy load (seriously depleted battery). They tend to cook from not having adequate dissipation. So I would...

    Yes it is because a standard cranking battery has little to no tolerance for more than a repetitive surface discharge.
    However, a consumer grade deep cycle battery will only give you a long and high...

    Joey,
    Yes Class D is generally 60% more efficient than Class AB so you would naturally expect a 60% increase in play time with the same power level before you hit the low voltage threshold. Although...

    Bazooka subs....
    The smaller 8-inch tube sounds the best although the larger versions will have progressively more output.
    The advantage of these are you can get by with a very modest amount of...

    It's much better to use a single active crossover filter. If given the option, I would set the source to 'full' and exclusively use the amplifier lowpass filter. I wouldn't want the cascading phase...

    The Kicker KM10 is a decent subwoofer but stands no chance in the factory application.
    I suspect that the KM10 is a moderately high 'Q' sub that will work just okay in an infinite baffle...

    The surfaces of a round pod in particular reflect back against the cone in a very coincidental manner. So you can get a profound peak at one frequency and a profound dip at another. This can add an...

    That's unusual that you would have a pronounced whine on the subwoofer amplifier that you do not have on the fullrange or highpass channels of other amplifiers since the sub amplifier lowpass filter...

    off2fly,
    Something isn't making sense here. Wetsounds absolutely repairs speakers. Period. And many here have experienced that. The replacement midbass drivers and HLCD diaphragms are very...

    A marinized amplifier is an essential if you are in a coastal or very brackish area.
    I would prefer that any fan-cooled amplifier has a conformal coating because you are constantly pouring moist...

    Yeah, crazy to replace the speakers without hearing them on better power. Source units may be rated at 4 X 50 watts but by the standards used by external amplifiers that would be a more realistic 4 X...

    The dual 4-ohm voice coil in parallel (net 2-ohm) on a monoblock amplifier is the right choice.

    Nothing sounds better than a subwoofer where the power nor driver is over-taxed. The rest is up to...

    Yes, 600 watts total whether you wire the voice coils in series or parallel. Either route is fine in order to get the best match with a particular amplifier. The only thing you should not do is use...
