JBL MPS1000 10-Inch 250-Watt Powered Marine Subwoofer Review

SUMMARY - Good price, easy install, clear directions, nice smooth sound, pretty substantial power.

THE WHOLE DEAL - if you are seriously thinking about buying one of these, here's some additional info:

Bought this on Amazon a few weeks ago, and installed it a week ago.

FIrst, Amazon service was fast, accurate and typical Amazing Amazon.

Second- the two reviews here do not give a very thorough idea of the speaker's worth.

INSTALL

To the guy who didn't get instructions, sorry about that pal. But, mine came with a decent instruction manual clear hook up instructions, and understandable details on how to do the setup adjustments. It also came with a nice thin cardboard template to do the cutout. This is really handy. My advice is to cut out the template both inside and outside, carefully, with a scissors. Then, tape it up where you want to mount the speaker. BE SURE that it is clear behind where you want to mount. The old rule of measure twice, cut once is truly appropriate here! Think about it and don't make a mistake. One good thing, mounting location for a sub is not very critical. Bass is pretty much non directional. Closer to the floor is better, but about anything will work OK.

Consider also that this thing is BIG! I didn't have a lot of choice where I put it. Only 2 spots big enough, and only one of those with easy access for wiring. This was on the captain's console, on the driver side under the console/dashboard facing the driver's shins. The boat is a 23' pontoon, and the captain's console is about 3/16" thick fiberglass.

I marked the inside hole with a Sharpie marker. I drilled the holes for the screws right through the template, which was taped up pretty securely. I used a cordless Milwaukee Hack-zall and a narrow, fine tooth Sawzall blade to make the circular cut from a starting hole I drilled in the marked circle. Take your time and cut carefully. The hole is better to be a little big than a little small. By little, I mean up to 1/4" oversize.

Mounting couldn't have been easier. Pop the whole unit in the big hole, line up the mounting holes with the screw pilot holes you drilled earlier and drive the screws in. A word about the screws - they are self tapping stainless steel. They are pretty long, and require some significant torque to drive home. A power driver is highly recommended. Use a #2 Phillips bit in the drill you used earlier. In my case, the fiberglass is pretty tough to get the screws through. I ended up stripping out the Phillips driver cross in one screw. If you are going into something hard, consider drilling the hole just a tiny bit bigger. When driving the screws, if it starts to get very hard do drive, stop and immediately back the screw out. Put some lube on it (probably Vaseline is best) and drive it again. Push HARD. If you let the phillips bit "cam out" of the slots, the soft stainless steel will easily become stripped.

Hook up couldn't have been easier, either! My mounting location was within about 3 feet of the back of the radio (I know, you're supposed to call it a "head" now, but I'm kinda' old.) The line inputs are short (10"or so) leads that exit the back center of the speaker. They have RCA female connections on them. For my installation, I needed a set of RCA male - RCA male cables, just like what you get with a piece of older audio gear. I had several Aux. power wire harness power points prewired in the boat, so it was a trivial matter to hook up the power. I didn't use the blue power hookup to the radio, but installed it with the positive wire. The amp turns on when I fire up the AUX 2 switch on my console. Mostly, in boats you want to actually turn *everything OFF* so there isn't some small current drain while the boat is sitting.

The wire harness had 12 gauge wire in it, a little smaller than what comes out of the speaker. It worked fine, though. My radio has RCA Subwoofer outputs on the back, so this was a snap.

PERFORMANCE

I am pleased with the performance of the unit and marvel at just how much better the audio system sounds with it. The book shows you how to adjust the input level, roll off frequency and BOOST. I left the level near max since I can easily set the subwoofer drive level from the control panel of the radio. I set the radio output to the middle of the range, then adjusted the sub for pleasing sound. I can now increase or decrease the sub presence from the head. Pretty slick.

I left the frequency roll off as high as it would go - 180 HZ. This is where it sounded best with the not real great 6 1/2" speakers that came with the boat. They have marginal bass, so the sub helping earlier down the spectrum seems to be pleasing.

The BOOST function is shipped adjusted to minimum, and that's where it should stay. Terrible. Muddy, boomy, thumpy and totally unmusical IMO. If you listen to hip-hop, this may be useful. If you listen to pretty much any kind of actual music, it is awful.

The boat came with a Sony marine head. Very unimpressive. It is replaced with a decent JVC HD radio with single CD slot and a AUX input. 50x4 watts, and a pretty good unit. The pontoon also cane with Sony 6.5" speakers (4). They also were not real impressive. Outdoors is a hard environment for any audio equipment, a boat more so, and a pontoon may be the worst of all. Almost no reflective surfaces or confined areas - just the wide open outdoors.

Anyway, the sub makes a huge difference in the perceived quality of the sound. I have it set up so your first thought isn't "wow, what a powerful sub", but so it is unobtrusive in the music but adds range and depth that should be in the music.

As for the guy who didn't feel it had enough power (!?), you can add a second one. They daisy chain using the RCA in and out just fine. I know I am taking a bit of a max power hit by having smaller power wiring than is optimum, but this thing kicks out way more volume than common courtesy would dictate that you run your music at. In other words, for anything like normal, enthusiastic listening levels, this thing is plenty powerful. (Also it is VERY nice to have an all in one unit with the amp integral in the enclosure.

The whole setup sounds so good that I decided to go the "final" fix and dump the original equipment Sony speakers and replace them with 6.5" JBLs.

I'm happy with it!

UPDATE:

FirST A CORRECTION - the 6.5" speakers that came with the boat were NOT Sony, but some off brand I hadn't heard of, kind of unlike what was stated at the time of sale. Sorry Sony.

Anyway, I ordered some new 6.5" JBL Marine speakers right after installing this sub. I got the 2 pair of them installed right away. I have had several opportunities to use the system with the all-JBL speaker complement, and it sounds decent. It isn't going to match the premium sound system in your car or home, but nothing on a boat is likely to. What it DOES do is provide pleasant listening across a range of music types, and from soft volume background music when just out floating around the lake with the engine off and the sun shining to listenable undistorted sound when pushing the pontoon flat out at 25+ mph pulling wake boarders.

The speakers I bought were

JBL MS6200 6.5-Inch 2-Way Marine Speakers

here on Amazon. Nice kit, includes long connection wires (I didn't need), screws etc. Very easy to mount to existing holes. Crisp clean highs, solid clean undistorted mid range and surprisingly more bass than what I took out. Together with the sub, this is a nicely matched system for not a ton of money.

You could get better stuff, but for under 4 bills for the sub and 2 pair of JBL speakers, and considering the limited and non optimal speaker locations on a pontoon, you'd probably have to spend a LOT more money go get anything significantly better.

Overall, a solid buy.

UPDATE Nov 1, 2011.

Well, the boat is shrink wrapped and stored for the winter. :-(

After substantial use throughout the summer and into fall, I can say that I am really pleased with the JBL sub and 4 JBL main speakers. I had a number of people comment on how nice the system sounded, and like I said earlier, it sounds good at lots of listening levels. The stuff is good enough that you can CLEARLY hear the difference between an analog FM station and when the JVC radio switches over to HD digital in a few seconds. CDs and HD sound very similar.

OVERALL, pleased with the JBL stuff, and would buy it again in a heartbeat.

SUMMER 3 UPDATE, JULY 2013
This is the third boating season I have used the JBL stuff, including this sub. Everything is still working just fine and sounds as good as ever. I am happy with this setup. As it turns out, while it is nice to "crank it up" occasionally, a far more important capability is how it sounds at moderate or low volume, low enough to still have a conversation but still have music in the background. I think this setup does really well here. Everything is crisp and clear and the sub keeps everything from sounding washed out and tinny.

STILL VERY RECOMMENDED
