replacing blown sub, with what?

[marvelusmarvcus 10+ year member]

ok, so i have had a ridiculous experience with my latest car audio install. bought everything new except the amps and had it all professionally installed. system sounded soo good for about the first hour.

alpine 9886 head unit-defective rca outs causing static

jl audio 13tw5-blown after 4 hours use, damaged voice coil

6 pr focals-sounding great thankfully

fosgate 800.2-working good

fosgate 600.4-working good

bought the stuff brand new off amazon. sending back the alpine for a replacement, and still dealing with the seller on the jl tw5. it looks like i may get a refund on the sub. if so, im not so sure i want to buy another jl tw5. if i dont i will have to get the car audio shop to make me a new box for the different sub.

i am looking for recommendations. i have a 99 porsche carrera with the sub behind the back seat in a sealed box. i want to stay with this design and it does seem to require a shallow mount sub? the guy at the audio shop recommended using the fosgate p3 shallow sub. i know there are probably some better options. i would say i am more about sound quality than extreme bass but i do like some low end.

any recommendations would be appreciated. thanks.

Voice coils only blow for one reason.... too much power. Set your gain properly and this will no longer happen. There is nothing wrong with those JL shallow subs.

i do appreciate the help.......

so, voicecoils cannot be affected by other factors like the enclosure size, leaks, crossover settings, too little power, manufacturer defects, damage by an installer, damage by a shipping company, tornadoes, lightning, and asteroid impacts?

interesting, lol

well, based on the specs of the speaker and the amp, i dont know how i could damage the voicecoil in less than an hour? the speaker was not even all that loud. i am thinking a manufacturer defect or something the installers did.

speaker specs

•power range: 150-600 watts RMS

•peak power handling: 1,200 watts

amp specs

•400 watts x 2 at 2 ohms

•800 watts x 1 in bridged mode

Not true...I could feed a sub it's recommended power but if it's a clipped signal, it won't last long...

//content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif It is impossible to blow a sub with too little power.

The TW5s are notorious for being really fragile. And you had a bigger amp than it could handle.

User error.

if any of those are the cause just throwing in a new sub won't fix the problem, other then a defective sub.

Confused by the 1 hour and then 4 hour statements you made. Did you smell the sub getting stinky, hear it bottom out, anything???

Nope they sure can't. How would enclosure size affect the voice coil? It can cause the speaker to damange its suspension, but not hurt the voice coil. It was user error. WHen you blow a voice coil, you applied too much power to the sub.

So what are you saying? Do you know what a clipped signal is? Are you saying that if you apply RMS but DC instead of AC that it will blow? If so, I concur, but that is not the discussion.

so, 500-600 watts is too much power for the jl 13tw5?

are you sure? the sub was not really working that hard, if i used less power it might not move

the first thing i noticed was the speaker bottoming out, popping sound. thought it was a poorly recorded mp3, so i went to the next song and all was good. bottomed out again on another song, seemed to not like certain frequencies. it worked great on the low bass, seemed to not like the high bass. i believe all crossover settings to be fine on the amp and hu. 3rd or 4th time it bottomed, it was done and had a tinny rattle at all volumes or even no volume.

installer says box is fine, crossover settings are fine, amp not driving too hard. they thinking a manufacturer defect. dont know what to believe. just scared to get another one.

so it bottomed out multiple times...and you changed nothing?

 

[snoopdan 5,000+ posts]

id get the replacement from them and then sell it... then buy a Pioneer TSSW3041D shallow mount 12, at least its claimed max thermal rating is 1400 watts //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif plus they're like 110 bucks....cheap.

was hoping for something comparable to the jl in sound quality. the jl sounded unbelieveable........when it wasnt bottoming.

All of the subs in the slim line catagory pretty much have the same SQ IMO...it's alot more to do with how your box was built anyway.

no, it really really sounded good
