Summary:
I have one of these in a Honda Civic, running off an Mtx amp putting out 450 watts bridged. For one woofer this sub hits hard. My friend is running two Fosgates and they only hit slighty harder. I first had it in a store bought box.I then made an mdf box to specks and it hit a lot harder. So if you git one make sure there is enough air space in the box.

Strengths:
Hits hard and plays low, takes power with ease.

Weaknesses:
The foam surrounds are kinda cheap

Summary:
The JL''s are a nice set of subs i am currently running them off of a boss 250x2 amp they hit hard and deep. They''re great subs to me for a larger SUV or jeep its not enough.WHich is why i want 2 10''s also probably im going to go with fosgates although i do like the jl''s there 10''s just don''t cut it for me. It does depend on the box you have them in but i would recomend these for everyone its a great sub. To me nothing but audiobahns can beat a good set up with the 12 inch jls.

Strengths:
Hit hard deep and pretty loud.

Weaknesses:
When cranked up with crossover set to 80 hrts they will carkle a little bit But to fix that i am going to get 2 more 10 which can hit a bit higher.

Summary:
i had 2 jl12w4 dual voice coil subs in a sealed box. They are the best speakers i have ever owned. No other speaker i''ve heard can hit the low notes like these. I had them for about 3 months bridged to a pioneer 600watt amp. For some reason, i think internal wiring, one of them overheated and blew. I would like to know if anyone here knows how much it would cost to repair the voice coil. Or maybe even buy it to repair themselves. I am currently running 2 12" PPI C1''s. They are decent speakers but nothing compared to my jls. They have a good punch to them, but no low bass at all.

Strengths:
amazing low notes, good overall speakers. If hooked up right they can take a lot of power

Weaknesses:
I guess they overheat if played at max volume for too long

Summary:
I have the subs in a dual sealed box with a Boss 1200 watt amp driveing them. These things are just unbelievable. My friend has 2 15" Boss subs and these just blow them away. My friends don't even like to sit in the back seat, they find it hard to talk. Way better than any thing i had before. The pioneers i had were pretty good but nothing caompared to these

Strengths:
Low, loud deep bass ....nuff said

Weaknesses:
Very responsive to what kind of box they're in
