Summary: I have a pair of these in my Subaru hatchback. I initially had them in a sealed box. They gave a decent thump, but I found them a little underwhelming considering what JL Audio is known for. I had my gain at -1 in the sealed box and it was alright, but I always found myself wanting to upgrade to something else. Instead, I recently ditched the sealed box for a ported box and it made a night and day difference.
Conclusion: I have had a few sub from other makers and this one so far has been the best. Best in quality of sound and it has a higher RMS than most. The other ones lasted only a few months and burnt out. Amp settings were correct too. I would recommend JL.
Summary: I originally had the JL 10w1v2-4 for 6 years and it was great. I ended up giving to my sister for her birthday for her car. I wanted something similar so I called in and the customer service rep suggested the v3 of same sub. It was shipped and I received it the next day. Installation was quick and easy. The sound is amazing. Sound is crisper, the bass hits lower and deeper. Overall the sound quality is better and my friends are jealous.
Pros: Crisper sound, deeper bass, sub seems to hit harder.
Summary: Have just bought two of these and have always been a JL audio fan. I received them today, and was very disappointed in how they were shipped. The box that Crutchfield shipped it in was very flemsy and had the speaker boxes falling out of the bottom almost, and half the Crutchfield tape half already torn apart on top.
Summary: Put two of these in a sealed box for my f250 from supercrew sound .5 cu ft per sub paired with a jl 600 watt mono amp Let me tell you these things hit way harder than I expected to bad they are hiding behind my back seat love to watch Em flex am very pleased with the results
Summary: Bought one of these to replace factory Bose sub in my car. It sounds nice if you listen to a lot of talk radio. I added a separate amp to drive this(300 rms) onto factory system. Put it in, with a good chunk of trimming and fab work for a box(.65 ft3) sealed in to stock location. It is about 20% louder than stock before it gets sloppy. I have an old cheap sub that sounds just about as good. Wanted to keep trunk space,but my alpine type R crushes this thing.
Summary: I have 2 of these bad subs in my f150 under the back seat in rhino lined sealed box being pushed by my MTX audio thunder 1000.1 amp! I was amazed on the amount of bass these subs put out! Also no matter how loud I crank it, the quality isn't distorted. If you want some bad subs with limited amount of space, these are them!
Pros: Compact, Loud, Quality, Reasonable Price! No reason not to get them!
