Hi all sifu in here, there's some problem with my jl 300/2 amp. Hope can get some help here.

The JL amp comes with 2 channel 150 RMS each and I only use it for 2 front component 55 RMS speakers. It should be more than enough to pump it. But recently the amp seems like getting easier to heat up, sometimes 5 to 6 songs in normal volume can cause the amp to be overheat (red light indicate). Strange part is: sometime I can listen music from KL till JB (3 to 4 hours) and the amp still works fine. I done the installation part in KF audio, I think it will not be their fault.

According to the manual, it will lower down the power output while over heat. But this is not what I heard in my case. I assume "lower down power output" will be something like decrease the volume or gain while listening. in my case it totally went off and come back maybe 2 or 3 sec. most of the time it sounds like signal distortion just right before it went off.

I really need some advise, please help. It will be much appreciate. Thanks.

try to check your
1. speaker wires for any chasis ground shorts...
2. your speaker still working properly? mayb the VC burnt?

cheers...

There's no ground shorts in my wire, by the way how do I check for VC burnt? thanks.

resistance test? i usually smell it... haha...

i didn't smell anything so far le.... but the speaker sounds clear as new.

By the way is there any JL audio service center in malaysia? thanks.

go back to ur installer la....

My installer is in KL, I am living in JB. install in there because of the craftsmanship. Even with those professional, a confirm solve problem will not be guarantee under this situation since my amp is not getting from the installer as well. I bought this amp from US. but didn't find any service center over here.

I suspect there's something wrong with the thermal detector or there's some connection loose inside the amp. That's why need all sifu help in here. If there's anyone in here have experience with fixing car amp please help. Thanks.

u might as well head down to 'famous audio' near southern college. thats one of the very good installer in jb.

Thanks. Went to that installer. But nothing done at last since the JL malaysia refuse to repair an US unit. Listen to the sound of their clients car, damn.... I'll do one of those when I got better.

since urs is not under any warranty, juz send to any technician to repair.

Only happened recently?

They can repair, but no spare parts available.

aikss... no spare part ga?

Because the spare parts hold in JL malaysia hand.

why not send back to your installer for warranties from JL then?

i think yours is still on warranties right?

Im using a cap ayam amp to power my mtx sub..always overheats so i extended the leg-air cond piping to under the seat..works for me! hehe i used the CAI rubber hose to extend and wrap the carpetting over it with double sided tape to conceal..

Hi, I have the exact same amp and owned it for 6 yrs. Have been running good as this while til recently it receives power supply but no sound produce to the speakers. Tried going to the installer for repair but to no result. Problem is all installer will send it somewhere to repair it but since you don't buy the amp from them, they are relunctant to repair it, hoping for you to buy a new set from them.

Where can i get this amp fix? Pls help....
