Don't you guys know that Old Milwaukee was voted "America's Best Tasting Beer"? At least that is what they said on tv. That was my beer of choice until a buddy switched me to Mich Ultra.

Eric; Are you in Brunswick? I grew up in Strongsville.

John, my shops in Brunswick, I live in Aurora Shores

Boat doc, altenator?
Ryan, Randy let me know if you need a cozy place to work... I want to get in on some of that expensive beer action, seriously the offers open

Saturdays are government days even though i poked at BFN's boat, today my uncles here putting a washer/dryer in his motor home and our tow truck drivers doing his brakes on the other side,

guys.........i have ordered ..

blaupunkt tha275 amp- 4 ohms 75 watts x2
                      2 ohms 120wattsx2...this will be powering my polk audio 650'.

ma audio m1889i monoblock-rms 4 ohms400x2 channel
                          rms 2 ohms800x1 channel

1 12" audiobahn eternal subwoofer
1 sealed box.............i have two new marine batts sitting in my basement....one for the boat one as a backup that was never used last summer....my problem now is that the audiobahn subwoofer and blaupunkt amp are backordered!.......so thats what im dealing with

Ryan,

Why are you ordering a two channel amp when you have 4 speakers? are you concerned that these are not marine amps? I would definitely make sure that the subwoofer is intended for marine use.i just looked at it real quick and it doesn't look like it would be a good choice for around the water IMO (Cellulose Fiber Cone and foam surround. This stuff will end up getting wet.

Hey this is ryan's buddy that's helping him pick out the equipment. I know car audio in and out, but have zero experience with marine applications so you understand where I'm coming from.

To explain the equip choices so far: (Skip if you don't care)
-----------------------------------------------
Ryan won't be doing any 5.1 or other setups that require the extra expense of a 4+ channel amp. (His audio is only 2 channels, left and right, so loading two on each channel @ 2 ohms total will give him the same wattage per speaker as a 4 channel amp costing twice as much or more)

The subwoofer has not and has yet to be picked out... that was a temporary sub I told ryan would be in the ballpark of wattage handling he would need if he wanted to go with a dual 4ohm voice coil, single sub. (Here's another one in the ballpark)

Personally I think he'd be better off going with two single voice coil subs (or two dual 2ohm voice coils in series then paralleled together etc) that are rated around 400w rms (Like Kappa Perfect 12s VQ's) to match the MA mono amp. (Which was an insane deal, why we're picking out the subs based on the amp instead of visa versa) He could run a dual 2ohm voice coil sub in series or a single voice coil speaker solo, but this would be using half of his system's potential :)

Anyways, he's not sure if he'll have the space for two 12's and I'm pretty sure isometric mounting of subs is a marine no-no since the basket and connectors of one of them would be exposed.

Oh and the buddy telling him using a regular sub is fine and such is another buddy, not me. What Ryan's said he's been told so far is the cone and surround just needs to be non porous like polypropylene.
-----------------------------------------------

Anyways these are my questions for selecting Ryan's equipment:

1.) Surely a plain plywood box isn't suitable for marine use, so what is the cheapest option that is still safe for an enclosure? (I'm not subscribing to Ryan's "it won't get wet" theory :P)

2.) Besides non-porous cone and surround, there are other major differences I see between the performance ratings of marine and auto speakers. Are the voice-coils water shielded/air enclosed thus why on average they can handle far less wattage? Are terminals waterproof? etc (what else besides cone and surround make a speaker "marine"?)

3.) With the answers for 1 and 2 in hand, can you use a regular sub if your marine enclosure is protective enough? And if Ryan's going with a cheap enclosure is he then limited only to marine subs?


I don't want to point Ryan towards something that will take a poop if it gets wet, why originally I was only looking at marine subs. But he's hearing from a lot of people that you can run regular subs fine, but I'm not hearing what the conditions of that are. (For instance "You can drill holes in your hull all day and you won't sink" isn't the same without the part about "as long as you don't drive it on water" hehe)


Anyways sorry for the long post, but trying to catch you guys up to speed since in the end you will be hearing about it more than I will ;)

EDIT: Oh yeah and forgot to ask if getting him a capacitor would be necessary, or just another battery instead, etc cause a boat doesn't exactly run/idle like a car... I'm pretty sure he'd have a few minutes tops with his system at full blast before he'd be paddling in a dead boat, so he'd have to idle if he wants to bump for the ladies, and without a capacitor, I'm thinking even on a boat at idle rpm would cause his alternator to give him the finger and shoot itself...

In my 94 ski i had 4 alpine marine 6.5 speakers. 2 MBquart Subs and all MTX amps. The subs were shot after season one baskets were rusted. They still played but looked crappy. To awnser the question i woulds buy a 4ch amp for the highs beacuse 2ohm is really going to work that amp. On A nice hot day it will start going into thermal protection or blow a up.Where are you buying the stuff from. I still can buy at dealer cost from the shop that i used to run. They sell JL audio Kenwood Alpine MBQuart MTX Rockford Clarion . So if their is some thing that u need i can get it and send it to you . I would ad a dual battery to the system. No Cap your Alt will work double time try to charge that cap . And the battery will go dead when the boat is turned off. If i can help in any way let me know. Like said before i am an hour and 45 from you . we have huge warehouses with heated floors so working in the winter is not to bad.   

here is a pic of a sub install

you could build that box ur self . Roughly about 45 dollars in wood and 1hr of time all u need is one sheet of 3/4 mdf and carpet. Do you have a table saw ? Then when you get your sub fig out the air space and build the box. You limit is 500 for the install or for the entire job ??

I built my box out of 3/4 inch plywood. Not marine grade, just good void free wood. I didn't coat it with resin, but I did coat it with black bedliner spray. Trust me, that stuff is tough. The sub I'm using is made by Elemental designs 13OV2 with 2 - 4 ohm voice coils. I can't remember the actual volume, but it's pretty close to what ED recommends. I tune the box to 28 hz with 2 - 3" ports. With less than 400 watts, the thing sounds insane. I believe it's because of the box design and where it's installed. I have it all the way up in front of my 89 Ski Nautique. The sub fires up while the ports fire towards the back of the boat. It's very sheltered and never got wet at all.   The only hard part was building such an odd shape box and then measuring it's volume. I'll take pictures and post them later. If I did it again, the only thing that I would do different would be to go with a quad 1 ohm voice coil sub.
