My boat has an Alpine MRPF320 amp with a channel for a subwoofer, the specifications for that are (100 watts RMS x 2 bridged output + 120 x 1 at 4 ohms)

my question is this, I want to hook up a Bazooka Marine Bass Tube either the 8 or 10 inch model, preferably the 10, its specifics are this:

4-ohm impedance
frequency response 39-1,000 Hz
RMS Power Handling 200 watts
Peak Power Handling 400 watts approx.

I'm thinking this should plug right in without any problems , and that the bass tube can actually handle more than the amp is able to give it, is this correct? Opinions/suggestions please.

Thanks,
M

You're on the right track, everything sounds like a good match.
As far as power goes, there is really no such thing as too much power from amp to subs. Power = driver control and unless you are a hammer-head you should be good.

Sub's are power hogs. I would not recomend running the Sub off the same amp as your mains. Even though you amp is setup from the factory to do just that. Unless you are always listening at lower volume levels you wont be happy with it. The power supplies on all but the very expensive amps can't supply enough power to drive the amplifiers.

Buy a good Class "D" amp for the sub and you will be in great shape.

Not enough juice. Buy a single channel amp that makes anywhere between 200 and 400 watts at 4 ohms. It's better to lean towards the higher side of the numbers. Class D is good for this application because they don't draw as much current or make as much heat as Class AB's will. Look for an amp that has a crossover with a slope rating of 24db/oct as well. Setting a crossover around 80 to 100 hz for a sub will have good results as well.

I have one under my rear bench (bazooka tube) just to round out the bottom.
Only needs a couple hundred watts normally... but I would not use an underpowered amp in bridge mode to make that happen.

I prefer running a larger amp unbridged.

But I do like that enclosure for my needs. Sounds good.

Bazooka also makes the same tube that comes with a 150 watt amp inside, coupled with sub channel on my amp should this be enough juice?

UNSANE

Well first of all you can't "stack" those amplifiers. Now the self powered tube's amp SHOULD be a good match for the speaker, it's still not a lot of juice but it is easy.

So if I plug the amp into the tube with the built in amp what will happen? I just won't have the "stacked power"? or....?

I am also considering the powered Bazooka. I have a decent Kicker Amp now, so wouldn't I just need to wire the Bazooka to the battery and then the wires from my existing Kicker amp?

Here's the amp:

Kicker KX1200.1

Part# KIC04KX12001

KICKER amplifiers have always ruled the winner's circle at car audio competitions because they combine remarkably advanced design features with the highest-grade electronic components and manufacturing tolerances for the ultimate combination of sound quality and brute power. The new KX series stereo amplifiers feature outrageous removable amp shrouds that scream “power.” Beneath the exciting exterior lies fan-cooled internals that have been designed from the ground up to deliver tight, clean power. Efficient Class D circuitry allows the amplifier to really pour on the power in 2- and 1-ohm operation. All this power is at your command with a continuously variable crossover, high- and low-level inputs, and defeatable subsonic filter to help protect your subs. Fast-acting protection circuitry guards against short-circuits, over-voltage, overheating, or wiring mishaps. Gold-plated RCA input and output connectors insure maximum conductivity and resistance to corrosion. High 22kOhm input impedance lets you link multiple amplifiers in a single signal chain without having to use signal-robbing splitters. Custom-tooled remote and speaker screw terminals are also gold-plated, while oversized power and ground terminals allow positive connection for up to 4-gauge wire. Dialing up just the right amount of bass is at your fingertips an included remote KickBass variable bass boost. KICKER even ships every amp with its own birth certificate – KICKER's guarantee to you that it meets their high standards for power and performance.

KX1200 is a great amp for subs...I'm surely hoping you won't hook it up to a bass tube..totally a waste...That amp can drive a pair of 12's or even a 15 like mad.
