XXX in a house

Don't waste your time breaking it in. It'll do that with regular play.

The amp shouldn't be clipping just because it has a massive subwoofer connected to it. And you certainly shouldn't be driving the amp into clipping if this is only to break it in.

probly wired the amp too low...

run the coils in series.

Do you even have to break these woofers in? I'll be getting an XXX soon so I want to be clear on break in. Is it necessary? Should I just install it in my car and play it low for the first day? or what?

Just play it like you normally would. Think about it; If you keep it low, how is it going to loosen up? //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif Just play it like you normally would.

Unless you normally get in and crank it to full tilt. Breaking in a sub usually isn't 'necessary', but its usually a good idea too. Most drivers Ive used from new had a break in period, and believe me it was noticeable. You do not want to drop in your new sub, sit in the seat and crank it. Play it reasonable the first few days, use your ears to listen for distortion, use your ears to listen for that distortion to lessen, and the output to rise as the suspension loosens. You can loosen the suspension without needing to drive the suspension to its limits, or even anywhere close.

well ive been driving around since tuesday

with my new SE's getting less than 300watts

Don't

 

[g30ffr3y 10+ year member]

Don't

i absolutely trust your opinions and advice... but

any reason in particular??? it seems reasonable

that the subs would need some time to loosen

up a bit... it also seems reasonable that the subs

wouldve been tested sometime during my 25 day

waiting period...

and sqeak... since ive got you on the line... any

advice on dampening the trunk??? what to use?

if to bother? where to put it?

Like I said above, use your ears. When the subs start to distort, turn it down. You will find this threshhold will rise as the suspension loosens. Break-in just means use your head, your ears and your common sense.

edit: if you doubt the need for a break-in period, go read a few professional reviews of subs in some magazines. Pratically all of them list how and for how long they did a break-in period before actually starting the tests. Must be something to it...

Well; First off, if you don't use the sub (i.e. play it at a reasonably loud level), then you are absolutely wasting your time. Barely using the sub (keeping the volume down) isn't going to do anything to help "loosen" it. Second, the sub will loosen up just fine during normal operation. Just use it like you planned on using it. Unless you are pushing the sub to it's absolute extreme (which, sorry, but you won't do that with music at typical listening levels), then you have nothing to worry about. Just play the sub now how you would play the sub a year from now.

Use layer upon layer of sound deadening //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif 2-3 layers on every surface is what I'd aim for if I were you.

what to use?

Raammat - http://www.raamaudio.com/products.htm (what I use)

Secondskin - http://www.secondskinaudio.com/secondskin.html

Brown Bread

Seem to be the most used

if to bother? where to put it?

Absolutely. You will do nothing but benefit from sound deadening. Put it everywhere; trunk (every wall/floor/trunk lid/rear deck if it's rattling), floor of the car, doors, as much of the cabin's side of the firewall as possible, A-pillars (help kill wind noise), roof. Don't have to do it all at one time mind you //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif But as your stereo progresses, that should be your ultimate goal. Doors and floors will also benefit from a layer or two of acoustical foam.

LOL.......not cheap? 36sqft of Dynamat Extreme (Dynamat's comparable product) costs $250. Which means 62sqft of Dynamat Extreme would cost $500......which means the Raammat costs 80% less than the "mainstream" brand //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif And if you e-mail Rick (the owner of Raammat), you'd likely be able to get him to sell it to you for $79 + shipping.

I was able to do 1 layer on my entire trunk (walls, floor, rear by taillights and trunk lid) and 3 layers on my drivers door with one roll.

Take some rough measurements of your car's interior where you want to place the material, you'll get a decent idea how much you need. 62ft isn't enough to do an entire car, but it'd do several key places, depending on the vehicle of course.

And, normally I agree with squeak, but I disagree using a sub at relatively low levels wont loosen the suspension. Again, check the pro's that test these things, they don't push these things hard to break them in. A spider for example will still loosen up even with less than full range of motion.

This isn't rocket science, its mostly common sense. The subs will tell you when they are unhappy, you just have to listen for it. As I said above, if you do listen for it, you will hear the distortion threshhold change as the suspension loosens.

I just push and pull them to full x-max/mus by hand one time.
