Question about Bazooka BTA10100 Car Subwoofer

6 Answers

Intermittent Problem Sub plays for a while, then stops, then plays again, sometimes several times within the same song. Sometimes makes a sound as it fades in and out of play. I opened it up and sure enough, the plastic bracket retaining the heat sink to the enclosure had snapped. I felt that this could certainly be related to the problem (everytime the bass would crank the heat sink would viobrate pulling on the wires) so I pulled on the wire and found that 1 of the 4 connections was a bit loose. I fit it back on, fixed the retaining clip and remounted the heat sink to its perpendicular position - feeling that I surely had fixed the problem. Not so. The device gave me about 15" of trouble free playing, I was convince that it had been fixed. I played the 3 songs that seemed to the problem the most: Lovers in a Dangerous Time (Bare Naked Ladies), Temperature (Sean Paul) and Fly Away (Lenny Kravitz). The sub failed midway the 3rd song. I was certain that this was a mechanical problem, one related to the vibrations of the speaker causing a loose connection somewhere. However, I'm not so sure anymore, I'm starting to think that this may be a heat problem. The vibrations in the first 2 songs were much more deep that those of the 3rd. However, the bass is working overtime with Lenny, it's constantly going and this seems to be what is triggering the failure. but if its a heat problem, why does it fade in and out and why the sound? Could it be a cold solder? If so, how do I locate the failure point? Any suggestions?

Your amp may be drawing too much of a load for the sub.
I had a Jbl 12" sub rated at 140watts @4ohm and a Jbl Bp300.1 amp with 150 watts @4ohm. I blew the sub and replaced it with a 275watt Jbl and every time certain tracks were played,(heavy on the bass) the amp would soft clip.

Sub, no sub, sub,no sub. Try lowering the volume and if this fixes the issue(temporarily) and only happens when these particular tracks play, then your sub may be drawing more than your amp can deliver.

I had to get a new amp. Jbl GT601.1 putting out 424watts rms @4ohm to efficiently run the sub.

If it still repeatedly done this... easy fix ..... fix it to where its working perfectly, and simply use epoxy to glue it. i have had this problem multiple times and this always fixed it. make sure before u use the epoxy make sure it doesn't conduct a current. this is easily tested also, use a small amount of epoxy, let it dry, and use it as a conductor to a multimeter. if this doesnt work, its not the equipment, its the user.

I had A ground zero 10inch subwoofer that did that same thing,When taking it apart i found that one of the voice coils where bad,You might need to take it and get the voice coils looked at.What happens is when the woofer has played long enough the voice coils start to separate.If over or under powered that could be one of your problems.

Posted on Sep 12, 2007

If there's a lot of high excursion time on the woofer your leads that go from the terminal block and go to the cone/coil assembley have a break in them somewhere. I have done this to many woofers and I personally have no problem with this woofer.(yet) Anyway you can't look at them as they are under the spider. The way you can tell is to turn on some music, any type, then push on the cone. You wan't to push hard and even on the cone so you don't scuff the voice coil. If the woofer cuts out there's you r prob. By the way completely ignore the other comment from The Marv. Hes is way off coarse.

One thing that comes to mind is you said the heatsink had come loose. if this was the case and it was the heatsink for the output transistors. Then this seems to be the best place to look for a broken solder joint. When either the unit heats up or vibration. One of the legs to one of the transisters opens this would case a half wave cycle drop. Do not know if I would consider the sound it would make as static. But it would become very garbled. get a bright light a slowly look over the circuit for broken solder joints use a magnifier if you have one. also wiggle the wires and tap on the circuit with something non-conductive like wood or plactic see if you can make this cause the condition. This may help narrow your search. Check as well on the top of the circuit look close at the transistor leads, because flexing back and forth can case them to break if flexed in the right place.

Works sometimes sometimes not

It could be a lot of things; such as, faulty wire connection, cold solder joint, HV voltage arcing, corroded battery terminals. intermittent short in the switches. If it stop work, try gently shaking it several times, push the on/off button several times. make sure the battery makes a good connection in the battery compartment. Wrap it up and put it in your freezer for a few hours. There are electronic components that might get hot/warm and by cooling them down they will start working again. GB...stewbison

Wurlitzer omt K99 the cd will stop during play

I seem to be having the same problem and all signs point to the serial control board board Pt# 0046630 under the player. The symptoms with mine were randomly cutting off songs about 20 sec after song start and returning disc to carrier. It started mostly when juke was first turned on (cold) and then progressed to all the time and now display on cd board is dark only randomly coming to life then dead again. power on the sub transformer is good and when it comes to life player works well. I am sending the board to be repaired.

USB-IPOD play is stuck. The receiver reads the ipod and tells me what song is up, but will not play. No error message and was working perfectly with same ipod before.

I have the exact same damn problem. It tempermental, whenever it wants to. I never had a problem until a few days ago. Sometimes I turn on my car and it will play a few songs and than when a next one starts it stops, sometimes right from the get go it won't work. Same thing as you though, it displace the song name but doesn't play it. Its so frusterating.

Yes, unfortunetly that does happen a lot! Sometimes the songs do not get transferred very well. Its usually a glitch sometimes in the programming. I usually try to download the same song again.

Movies on my recorded discs freeze after a few minutes of play

Sometimes this unit gets "confused" - not sure why -- but try first using a CD cleaning disk and let it start and stop a couple times (sometimes lens gets dirty and does this) - if that doesn't help then try unplugging unit and leave unplugged (from wall socket) for about 30min then plug in, set local time and then see if the disks play okay - sometimes this "resets system"
