Replacing an old sub

[tejcurrent 13]

Well, my brother purchased a kicker L7 12 about a year ago, and was powering it with a 1kw kenwood amp that really put out more like 3-400, and after selling him my bxi2006d he noticed that he kept hearing a slapping type sound. He pulled it out of the box and you could just smell the coil, and the sub was very hot to the touch. It wasn't the tinsels slapping or anything, it was something inside. He probably messed it up with that crappy old amp, so now he wants a new sub. With the hifonics amp I suggested a dual 2ohm BL with cooling, flatwind, and p chamfer options. This is going in the center console of his chevy 2500, which we'd really be making the box into a center consol, with about 2cubes tuned to 33-35hz. Does this sound like a good combo, or would another sub be better suited? thanks.

I vote SSD 12 copper coil.

agreed

Well, 2006d is supposed to put out 2kwatts at 1ohm, but I think it's more like 17-1800, so that is what he's going to be working with. He wants to take advantage of the power at 1ohm, would a single 12" ssd still be the best option? I know the ssd is the closest to the L7, but he wants to upgrade. Would the SSD handle the extra power? Or do you recomend the ssd because of the small enclosure size? Whatever he uses I know him and he will crank that amp on it. Thanks.

i wish i was that lucky. I have been powering 2 Diamond D1's off of a DD m1 amplifier, and yesterday on the way to work the amp shut off and wont turn back on. I checked all of the wiring and my other amp still works. The guts look the same they did as the day i got the amp, nothing burnt or exploded. I have yet to take the box back out of my car to check the subs as I am guessing that I melted a voice coil so the amp doesn't see a proper impedance load. If that is the case than new Fi sub it will be, if it isn't than i quit car audio.... lol.

My subs were slapping whenever i turned the volume up and i wasn't trying to preserve them at all, just wondering how long they would take the abuse. So i am really frustrated that the amp gave out, and not the subs. Oh well, once the temperature gets back above a negative 20 degrees with wind chill I'll work on diagnosing the problem.

That really sucks! and the fact that its -20 degrees! it hasn't dropped below +20 all winter here in Myrtle Beach SC. Good luck, but yeah, he mistreated that kicker-I wasn't too surprised. So pretty much your whole system is dead?

Nothing says you have to use all of that power either

It'd be much easier on their electrical system as well.

My bro wants to use all the power, he wants a sub to match that amp. Would the SSD really be better? I'm just trying to find out why. Thanks.

If he wants all the power then get two SSD's and parrallel them to the bxi2006d... Maybe 2 10's if space is an issue. (I hear scott loves his ten SSD and that says a lot when the guy has the pick of ANY sub he wants to machine up)

Audio neon can you just switch the speaker wires to the other amp and if the speakers play then your amp is BYE BYE and if they don't play ORDER UP 2 Fi with everything on it

MY other amp is still running, its powering my front components. I just don't get how my DD m1 failed, it wasn't being stressed, it wasn't even warm. It was just clicking off test tones at 36 out of 60 volume of my eclipse cd8455, with the non-fader set at +3. I am going to hook it back up in my car and see if it at least turns back on right now, ill let you know shortly.

The m1 is at audio obsessions getting bench-tested right now. If it is in fact dead, i will be ordering a DD m1a today. And in two weeks be buying my Q.

I'm just trying to understand why the ssd? He doesn't want 2 subs, and really only wants one so he can say 'look how loud my one sub is'. I'll be making a box to fit on his seat in his single cab truck, He only has about 6-8" at the bottom to put a box behind the seat, so I will be splitting his bench seat with a box, but his shift lever is on the floor so it'll have to have some weird shapes to it to even get the 2 feet, but that is what he wants.
