I have a AI Design footwell sub box....it came with the JL Audio 8w3V2 D2 driver....the sub seems to be defective as the wires to one of the voice coils have began to fray....so I can replace it with the same driver, under warranty....or replace it with a better driver....The Boston Acoustic/Momo competition driver will work, and I can put more power to it...there is also the Infinity Reference, and the Rockford Fosgate....I am not sure but I think the Fosgate is too deep for the box...any ideas? The Amp is an Audison LRX 6.9, with Focal seperates in the car....The JL Audio did sound VERY good....but I did have the amp turned down to about 7 because the driver was not rated for that much power....so maybe better driver and I can turn it up more? Even though its LOUD enough...lol....

 

maybe better driver and I can turn it up more? Even though its LOUD enough...lol....

Sounds like more disturbing the peace tickets... if the original wasnt cutting it (or defective?) time to upgrade, maybe this time it will last longer, but then again you'll be cranking it... vicious cycle

 

Yes...I know...as I was writing that...I was thinking...why am I trying to get MORE power???? lol....

Yee the original was defective....so maybe a better sub will last longer....or maybe I wont get a bad one the 2nd time around....

 

The sub may not have sounded good b/c the sub box maybe too big or too small. JL are good subs. Find out the volume of your sub box and pick a sub that recommends that air volume. You can have a bad *** speaker in the wrong box and it will sound like ****.. just my .02

 

The subs I am looking at work with a similar amount of volume.....the original sub sounded AMAZING...not complaining about the sound of it....

 

exactly what he said....

just be careful sticking any old sub in there. Hope to meet you one day I want to hear that bad boy.

 

I'd take a look at some RE subs, or if you can find some IDQ 8's. I've had boston pro subs before very nice in a small sealed just couldn't stand up to the power i was giving them.

I personally love the JL subs. I've been running a 10W3 for a long time with 250 watts to it and it sounds great. It just sounds like you got a defective one. It you are happy with it, I would just get a warranty replacement. Or maybe upgrade to a 8W7? (probably won't fit in the box)

 

Yeah....8w7 will NOT fit....only have about 4 1/2 inches of depth in the box....
