  • Using car speakers in a boat

    So I am putting my stereo in next weekend, I have a car stereo that I am mounting in the glovebox to keep it dry. I have a question about speakers though. I have a low budget, but I am looking for great sound (I know that sound ludicrous). Anyway I can either get 1 pair of kicker marine components (6.5), or MTX non marine speakers (2 pair). The mtx speakers have poly cones and rubber surrounds, which I know will hold up fine. I worry about the cloth deal below the cone (in picture below) and the rest of the components holding up. Please help me, I dont want to have to buy speakers in the next year or two again.

    (that part is called the 'spider' btw...)

    Anyway, the only requirements are poly cones/rubber surrounds, like you mentioned. It is possible SOME marine speakers might have UV inhibitors also, but even without that, you will get at least a couple years of service out of regular speakers. As far as the spider, it shouldn't be exposed directly to water anyway. if it is you need to seal up your boat a little better!


    different question, are you mounting the speakers in box? Some speakers are meant for open environments/open baffle, some are not. For 6.5"'s it doesn't make a huge amount of difference though.

      I would think they should work if kept dry, cars have speakers in the back window and that's in the sun.

        Thanks, since it sounds like you know what you are talking about could you answer another question. I am trying to decide between these items and I dont know which way to go.
        I can get 1 set of these...
        KICKER KM620.2 (marine components)

        Or

        1 set of MTX XT693 and 1 set of MTX XT 502 (car speakers)

        I like the idea of having 4 speakers, and I have heard that my kenwood head unit may have issues of pushing the components. But if I will get much better sound with the components Ill go that way.

        Thanks

          I consider cars to be a pretty harsh environment. Don't get them directly wet and I don't think you'll have a problem.

            If this is afresh water boat, go for it. I have always used "car speakers". In fact my current front pair are ford ranger take offs, paper cone and all. Been in the boat two years now and still runnin' strong. I got them for the angled surface mount grills, but they sounded SO MUCH better then the marine speakers that were in the boat, I lrft them in. They are getting upgraded this year (probably kenwood or alpine), but I am doing for better sound quality, not because they have deteriorated.

              fwiw. i'm using a auto stereo in my boat. a panasonic indash + 4 ea. panasonic 6.5's (plastic cones). so far so good. this will be my 4th year with them installed w/o problems. i know for sure one of the rear speakers has had water dripped all over it (from entering the boat on a ladder from deep water) and my indash has ingested water so bad that the display went away and it didn't work at all. after it dried out it become fully operational again.. that pretty much amazed me...

                I would suggest you look at Focal's Access line. I believe they are 165CA for the 6.5s. Awesome speakers at a reasonable price.[/tangent]

                  Without an amp your head unit should push a pair of 6x9 and a pair of 6.5 fairly well if its a newer unit. Is it going to win a comp. no but it should be acceptable for what you are trying to do. If you peg the volume it will sound crappy due to not enough power, so dont peg the volume. Most average systems aren't loud enough to rock out while under way unless you are fully enclosed somehow. If the auto units are kept mostly dry they will be fine, even a marine unit will be trashed if it takes a wave of water into it. Mount them in a place that won't see water regularly and yopu should be fine. If the sound isn't to your liking a small amp could be added and really add some snap to it.

                    The focals are way too expensive, well over 100 per pair. I know the head will power the coax speakers fine, I just was curious if it can power a component set. The components can handle MUCH higher wattage, so I didn't know if it they needed higher wattage to drive them.

                      Like I say it is rated to handle 4 speakers, its when you start going into the upper half of the volume range you could start to see or hear problems. A 100w amp would be a nice addition to the system in the future if funds allow. But for now I would have NO hesitation in hooking it up with the 4 speaks and going for it. You may be pleasently surprised at how it performs, big sound and clarity requires big money. Since the money thing is affecting us all go with what you have and see from there what else you may need.

                        You can always power a set of components with whatever power you have...but it might not sound very good. But this is entirely too broad of a question to answer. Proper installation goes a LONG way in sound reproduction, as does listening volume, power handling, output power, environment, etc. Usually, though, components shouldn't be run off a head unit's power. If you install them properly, and have a really great amp in your head unit, and have crossovers set to fade out the low end and subwoofers to take up the slack, then yeah it could work...but generally I'd go with a resounding no.

                        And my Focal recommendation was for the person I quoted who said they wanted to replace their current speakers with better sounding ones.

                          I had some automotive 6.5"s that i put in our boat. We got stuck in a bad storm and they got soaked and started shorting out. I left em in, and next trip they were kinda shorting out again so i pulled em and went with marine 6.5"s and i plan on adding some 6x9"s with maybe a small amp. head unit is automotive kenwood with a splashguard.

                            i consider what i have to be average. 200w or 4x50w, no amps or sub woofers. ft. speakers are just in ft. of the merControl, right behind the dash, aft speakers just in ft. of the aft seating on a 19' boat closed bow boat. i fade 2 or 3 to the rear and it's pretty balanced out. i do have a hardtop, but the hardtop slides to the rear and when it's slid back, still plenty loud to hear while underway. w/o cranking it too.
                            If the auto units are kept mostly dry they will be fine, even a marine unit will be trashed if it takes a wave of water into it.
                            and that's what happened when i injested water. i took a wave over the bow from a cruiser and stuffed my bow into their wave. top slid back. the waver went right up the windshield and dumped it right on top of my indash, which ejected the cd i was listening to and funneled the water right down the cd into the indash. it took a week of sitting in the sun to dry the whole boat out let alone the stereo.. while i'd tend to think what your saying is true. mine does in fact still work (which is amazing to me also). took the wave two summers ago.
                            again, i got auto stereo components all around.. maybe i'm just lucky it still works, i don't know. just my experience..

                              Smokingcrater is dead on. The only other thing I'll add is that with my Pioneer Marine speakers the spider is laminated to reduce rot. I also use marine amplifiers which have the circuits siliconed to reduce corrosion. However, if your cautious about where you mount them automotive speakers will do you just fine.
