Hi,

I'm very much new to installing mobile audio. Having said that, I have a boat with a Kenwood head unit powering 4 relatively competent marine speakers.

I'm thinking of installing a Marine Bazooka Bass Cannon to give the system a bit more Oomph, although I really don't want to go overboard. The one I was looking at was the MBT8014:

Thing is, I'm unsure what a "Passive" tube means, although I'm guessing I need an amp to drive it (aka: there's not one built in). The install instructions suggest 2 bass cannons for a bowrider, but I want to start with just one and see what it sounds like.

So.....what's the best way to go here? Buy the "Passive" tube and a marine amp (if necessary), or buy the more expensive "Active" tube (which seems to use less power, 100W vs. 150W) and just plug it in? If I go with the external amp, how do I size it so it properly drives the tube?

Thanks.

 

No opinions from anyone? Anyone have alternate suggestions?

 

I personally would run 2 of the passive units with a 4 or 500wrms amp. In your case, a single tube with around 200wrms would do just fine

 

Sounds like a good plan. The other thing I need to think of is whether I want to install a two battery system or just risk draining the one that I have now.

 

i'm not too sure bout marine audio, but that kind of power wont hurt ur alternator too fast, but i would still bring another fully charged battery or a battery booster with you incase it does.

 

The issue isn't so much the alternator as it's common to run marine audio for hours without the engine running. Usually, a deep cycle battery handles the task, although a second starter battery is wired to provide engine start power. Then there's a switch that routes the power for the systems from one battery or the other, or both. The thing is, do I want to run up my costs by installing this second deep cycle battery and associated switches?

 

for that power dont worry about the alternator unless u drive a firefly with a 40amp alternator lmao.. and battery wise stick with 1. if i can run 3 hours straight full volume on 1000watts rms and still able to start my vehicle i think that u should be ok..

 

I would if I was you......nothing like mooring the boat somewhere, partying with the tunes going all day in the sunshine and then having to tell your friends it's time to start rowing.....

Up to you tho.....

HTH

 

Psssst.....he's in a boat, dude....

 

Run a second batt, cuss and spit at the switches if you want, but it will save your hiney Hauger lol
