Summary: I have 1 10" Alpine with the fosgate m750-1d amp pushing it. My head unit is a clarion m303 and the head unit powers 4 alpine 6.5" marine speakers. I put in in a 2003 seadoo sportster. It is used in a free space and this thing sounds nice. You can feel the bass and it sounds very clean.
Summary: Just installed this sub in my Rinker 262 Captiva. It's mounted in a less than ideal location, and vents into a large open storage compartment, so it's certainly not an ideal environment for making low frequency sound waves.
Pros: Looks good, Sounds great when feed appropriate levels of clean power.
Summary: These subs absolutely rock for the money. I bought a pair of them for my boat last year and I am amazed at how much sound they put out and how hard they hit! I am pushing them with a JL 900/5 marine amp and they take all it can dish out. Definitely a solid choice over some much more pricey options.
Pros: Less expensive than JL option Hit Hard Great sound
Summary: Plugged right in. Sounds way better than the Clarion Marine junk that was in there. Cheaper too. Larger magnet than the Clarions so sits deeper in the mount. Had to modify the mount to get it into the hole. Very satisfied with the sound now.
Summary: I installed this 10" sub on my boat with a clarion head unit and a 1000 watt Pile Amp. I am driving it with a 500 watt bridged circuit and the sub rocks!! It hits the bass hard and clear with out any distortion.
