Adding a 10" Subwoofer

[tjwieseler]

I was wondering if anyone has added a 10" subwoofer to a 2400 SCR. I have recently purchased a 1997 2400 SCR and I am thinking about adding one on the starboard side just behind the mid cabin window. Just wondering if anyone had any experiences with that.

Mines a 95 SR2100 and I have 2 10's that I ran last year in the port side engine bay in a 3/4 inch high density box and it held up great! But, that compartment is Soooo sealed to keep out engine noise that it also severely dampened the acoustics. Open up the lid though and D#MN! I had the rock'enest sh#t out there. (there is a ton of room in there). I have recently purchased the Corsa side exit exhaust that is going to prevent me from having the box in there.... My plan is to place the box in the ski locker under the back seat and port it through the front. I will have pictures when I'm done of both the exhaust and the stereo system.

I can tell you from experience that fiberglass does make a nice acoustic environment 'IF' done correctly. This is the catcher... IF DONE correctly..... to do it right you are going to need to find the optimal amount of air space for the woofer you are using and block off the bow and stern sides with treated wood. I would use expanding foam sealant to keep the blocks in place and make a nice sealed enclosure. It could be awesome, but like anything else.. it's about the forethought and what you put into it.

Good luck!! and please keep us posted on your progress!! - DB

A Friend of mine added one to his Baja, and it does sound great... However, he found out after the fact... that he needed an additional battery to supply enough power for the amp and sub. Unless you run your boat non stop I'd think about that... Good luck!

I was planning on just cutting the hole for the sub and having it face directly out of the side. The bow side is already blocked off, but not the engine compartment. Are you saying I should still build a box around it on the inside of the compartment. If I did build a compartment around it I would think you would have to have an vent hole to allow the sub to move effeciently.

I do plan on adding an additional battery, maybe two. The amp that I added is just a 500 watt and has a maximum draw of about 40 amps, so if I did crank the tunes it could eat a battery right up.

You are exactly right, some subs are meant to be ported others are designed to be in a sealed enclosure.

Porting a sub is a technical job also. The diameter and depth of the port both play an important role in the frequencies the sub is able to produce. I’m not trying to scare you away from doing this, just want to help you make the right choices.

Can you provide any specifications on the sub you have?

Suggest you download this. You will need adobe to look at a PDF. It has manufacture suggestions for both air space and port length.
Why 3 channel? Are you also adding some 6.5's or something? If you are just powering the sub you probably want mono bridged.

[tjwieseler]

I see that I do need an enclosure, and looks like I can do a vented or non-vented. I am planning on building the box and putting it behind the inner wall. It looks like there is enough room for the small enclosure.

Yes, I have a pair of Sony 6.5 component speakers hooked to the other channels.

I have an additional pair of the Sony's inside the cabin that are hooked right to the receiver, with a switch for the remote wire going to the amp so I can turn the sub off when we are inside the cabin watching a movie or listening to music.

[oneradride]

Sounds like you have a good plan!! Please post some pictures when you get her all buttoned up..

[tjwieseler]

Here are the pictures of the final installation. I think everything turned out well. It will really crank the tunes out and have the flexability to watch a movie in the cabin.

[oneradride]

Either its warm there or you have a big garage… I wish I had somewhere to work on mind right now!!!
You are making me jealous! Install looks great, nice job

[tjwieseler]

Thanks,

I have a really large 100 x 120' shop at my work that I have taken over a stall.

Just been working on adding two 12inch Subwoofers to my Maxum 1800sr. Still not finished but getting there!

I took a subwoofer box and cut it to fit. Working on enclosing and porting.
The plan is to add extra tweeters and next summer speaker cans on the wake tower.
Total 600watts RMS NOT Peak!
These are MTX Thunder 5500 12inch but are not marine grade. I had these from a car.

[tjwieseler]

WOW, you won't even have to start the engine to have a wake around the boat! Looks like it will really rock!

TJ,

Does that lcd swivel mount provide enough stability to keep the lcd from bouncing around like crazy while under way, or in rough water? Or do you secure it additionally? One last question, how the hell does the microwave come out? Mine seems to be secured somehow with no visible points that I can access to remove it.
Looks great!

The swivel mount has the thumb screws to tighten up each joint, so before getting under way I tighten each one so it won't move. I haven't had any problems as of yet.

My microwave has a single phillips head screw that holds it from underneath. It goes right where the ruber foot is on the right rear corner of the microwave.

Well Done TJ! Go ahead and write yourself out a check for $500.00 for the great install!!

Thanks Bella, I will see if that check will buy me any fuel this summer. For some reason, I doubt it!
