JL 12W7 is crap????
i just recently bought one JL 12W7 in a sealed box. From what ive read its crazy bass for one sub. I have a alpine mrpm1000 amp wired to it and full the gain is all the way full. The amount of bass coming from it is nothing for what i expected. I just wasted a ton of money it sucks. Its on the back seat of my truck and im absolutely disappointed

w7's are nice subs. sounds like you have something sketchy going on.
....and i'd rethink running an amp at full gain. thats just asking for trouble. nothing will make a difference as much as a box will. providing there isn't anything broken or malfunctioning, get yourself a nice ported enclosure built for the sub. |
Sounds like it's time for a new enclosure. :sly:

here are the facts:
W7's are good subs by anyone's yardstick they can get loud with music but are by no means the loudest subs available they sound very good, but others may prefer other sub's sound quality they tend to be priced higher than comparable subwoofers, but do offer very good quality and craftsmanship therefore, there is something else causing the poor performance you're getting. possible problems: damaged or defective subwoofer poorly constructed or designed enclosure poor position in vehicle amplifier problems poor source material unreasonable consumer installed incorrectly or wired improperly my suggestion, seek the help of someone who knows what they're doing. |
ya it may be the enclosure i could only get the top 4 screws mounted onto it out of the 12 cause the subs screws r like inside the damn thing. I wired it correctly as 3 ohm. positive from amp to positive on sub and negative to negative

Failing that, check the settings for the Xover on the amp.....it also sounds like you could have set it to HP mode.....:smokin: HTH |
it is a doo doo sub. welcome to the real world.

well you have your answer from your buddy's install...maybe he can take a look at it for you and help you figure out what's wrong.
|
i'll trade you mine for it and give you $50....
|
why are your gains all the way up?
|
Ya, they suck. Overrated, over-priced, well built sub. The w6 is a way better sq sub.
|
mine shakes the out of my car so it sounds like an encloseure issue or a power issue, sure ur amp is running 1000 watts but if ur powering it with 14 AWG it aint gunna do lol
|
well there is a list already of things that should be noted or fixed before passing judgement on the sub.
..fix the seal/mount of the sub ..bad placement of enclosure ..improperly set gains ..note that the amp is a 1000 watt amp at 2ohm. 600 at 4. somewhere in between at 3. so decent power...but w7s are pretty thirsty beyond that, something has to be malfunctioning if the sub doesn't even sound like a little 150watt setup. regardless of the enclosure. |
Definitely a install problem, the W7's require a very precise box, make sure your box meets their requirements

its probably just a instalation problom also could be the controls on your deck sub and basss could be turned off or turned down , and you could definitly buy a better amp to run that sub to max performance but none the lessss ask anyone on this forum and theyll tell you its all in the box
|
i agree with everyone else, i have a 12w7 in a made to spec ported box and i love it, shakes the out of my car! besides ur gains shouldbt be all the way up:S my gains are at 0 right now and it still pounds. Definately amp/box/sub problem, w7 is wicked for what it does!
