Well I am wanting to do one and need to figure out what the jeep can handle. I am wanting to do 2 Fi btls with 4000-5000 watt amps to each subs and want to kow if the back window will support that. Thanks

 

Good question? If I where a betting man, I would bet on not!

 

the hatches are a rather weak point on xj's ( i broke 2 before the chop) id bet the hatch seals blow befor the window breaks any way just my 2 Cents

 

Yeah but they are super easy to replace too.

 

They will handle it just fine. There is a guy on here who thru a 128db??? i think it was a box that took up the whole back seat. custom wood box was formed to fit from floor to ceiling.

here is a video of what will happen to your hatch:

Man...some people really love bass.

I like it, but to me, anything that is disturbing residences 500ft away is just overkill. I am running a single 12" at 500W, and it can hurt my pretty resilient ears, but is still pretty unnoticeable from the outside. What the heck are you guys doing to your ears?

Please turn it down is residential areas.

 

Sure it will... with the subs turned off or way down... and even with it up to power for a few seconds... Man I am happy with a single 12 like Floyd runs... I am actually looking at getting an Infinity BassLink II for my setup... maybe add another one down the line somewhere if one isn't enough, but from the ones I have heard before I should be good with just that...

 

Because most subs will over power the other speakers. (thumper) That is why I have 250 Watts each, going to the four corner speakers. And only 400 watts going to my sub. I like the full range sound of music , not just the thumping. In other words, I like the hear music exactly how it was recorded. From the rich deep lows of the bass, to the super highs of fingers squeaking on the guitar strings. And everything in between!
