Question about Car Amplifiers

MA Audio HK4002

I am getting bored with seeing this amp sit in the corner of the basement collecting dust. I had it fixed once by a local repair shop (highly recommended in the area), and it blew on me when I hooked it up. Upon the re-fix of this same amp, it was installed by the shop installer, only to emit a disgrunteling pop as it died again. They wern't happy now, and I could see this. The third fix was then handed back to me months later, as I installed it in the truck, got some noise, began jumpin around like a 12 year old in a candy shop, and then.... ZERT. It truely must be the cursed amp. I have given MA lots of patience, but here it is 3 years later and my Memphis ST1000D still hits every note without a hitch. I'd be fine with it so long as I don't crave more, but I do. Do you have any info on how I would send an MA Audio product back to the manufacturer for repair? I'm already 245 bucks deep in repairs on this bad boy, but if it gets me an amp that will power my Immortal Series 15, that'd be worth looking into. Sorry this is so long. Mike

Re: MA Audio HK4002

Well if the Repair shop comes highly recommended, they should not have charged you if the repair did not last. I run a repair shop and everything I repair comes with a 90 day warranty. No way will MA take your amp back now that a repair shop has busted into it. I can feel for you about wanting it to work. I am very surprised you still are trying. I do not have a remedy that will be free. Get yourselof on track with a new amp for Christmas, keep the receipt this time and try the manufacturer first before going to a repair shop. I know I might get a bad vote on this comment. Sorry

Jl audio 1000/1 problems

Hello l_miller36,

Depending on how much you paid for the amp on eBay, and how well you like the JL product, it may very well be worth the money to get it fixed. As for the wallet damage, you'll have to ask JL or one of their dealers. But, since the Slash2's routinely sell for over $1,000, I'd estimate the cost to be pretty high.

First, I'd send an email to JL Audio tech support and see if they have a "flat-rate" repair option or if they can give you an estimate of the repair costs. My second option would be to talk to a local car audio shop that does component level repairs. In the first case, you'd get exact replacement parts and whatever warranty JL gives on repairs. Not so with the local option, but it would most likely be less expensive.

Hope this helps, good luck.

No out put

It sounds like the switching power supply has failed.

You need to find a local repair shop. If you don't know of any, contact the local car audio dealers to see who they use. If several recommend the same shop, they probably do good work.

If you want to try to repair it yourself, you'd have to do a bit of troubleshooting.

Let me know if you have any other questions.

My jl Auido 250/1 amp

You may have a bad output on the amplifier. I would recommend taking it to a local electronics repair to have fixed, or visit a local stereo shop - preferably a JL Audio dealer. Visit their website at to find a dealer near you. You can have your amplifier sent in to JL Audio for repair by an authorized dealer and you'll get a warranty on the repair work.

Where to take my amp for repair

Contact Rockford for factory service.

If you don't want to send it to Rockford, ask the local audio shops who they use for amp repairs. If several use the same repair shop, it's probably a good place to send your amp.

Low ohm light on my jl 500/1

If the low impedance light is on, the amp probably has shorted output transistors. If you don't know of a good local repair shop, call 'several' of the local audio sales/installation shops to see who they use. If more than one audio shop recommends the same repair shop, they probably do good work.

Power to amp

It sounds like the power supply has failed (burnt smell). Any local shop that repairs car audio should be able to repair it. If you don't know which shops repair car audio, call the local car audio dealers and ask them who they send their amps to for service.

Driving in first gear

Your Amp is in protect. Disconnect your subs and turn it back on. IF the led goes back to green the you have a blown Sub and it will need to be replaced. If the amp stays in protect even with the subs removed the the amp is toast.
