good to know... thanks!!!

 

has anyone with a non-ML system ever had a Panasonic amp go bad? I dont know who makes the ML amps, but they seem to have a very high failure rate from what I read

 

Thanks so much for your valuable information, my LX-470 suffering same thing and i will be sending to United Radio, i just learned about they company and they are BIG and highly reputable company. Quote is same as flat $325. I will not buy use from ebay with high risk nor exchange from dealer. Because United Radio still offer one year warranty. Company seems very organized. I sopke with CS lady and they are very professional. How is your unit working as of now? I can be reached at yenyunt@bcbg.com
Thanks again
Ye

 

wow, thank you for posting..i got the 100K warranty, so hopefully if mine goes out, it will do it before then, but this will make a lot of folks feel better

 

This is FANTASTIC info!!! Thanks so much for the info, OP --> oscarls460! This is great. What year is your LS? '07? ...and the amp went bad already !?!?!? Jeeez. My GS430 is an '01.. really a "MINT" car- but I'm surprised my ML amp has made it THIS far before blowing...with all the things I've read about their interals/heat sinks, etc.
WOW.

 

Maybe it only seems to me like a lot of these thing are blowing, but there appears to be a real problem with these amps. If that is truly the case, Lexus should warrant these for a longer period. If not it might be cause for a class action suit.

 

The car audio shop that did my aftermarket upgrade said they get a LOT of people coming in to replace blown ML amps.

 

thats a 19 channel amp how could they replace that for anywhere near $325..

Im workin on upgrading the whole system (minus headunit) an to do it properly and retain dolby dts u need no less than (3)4 channel amps b4 u even start w sub bass.. I know phoenix gold jus released something "plug n play" but thats a 5 channel w a built in sub.. Plz get me some more info

 

I think he has a place where he can get refurbished ML amps. But I'm sure they charge a lot more than 325. Sounds like United is your best bet unless you want to spend some jack.

Mine was non-ML so I only needed one JL amp and an oem interface unit.

 

that makes sense..

 

My amp just went it is ml on a 07 .Speakers front began to rattle at high volumes and only on hot days . I started to notice it when the trunk was full but thought it had to do with distortion of the base seing the trunk was full .Had 1 day of warranty left when I took it in .Waiting for new amp .

 

Mine was replaced under warranty at around 25,000 miles. After noticing where the ML amp is in the trunk, my thought is that perhaps they are overheating. I imagine that with the high quantity of speakers and the relatively high quality sound for a factory system, that the amp may generate a decent amount of heat. I wonder if removing the part of the trunk floor covering the amp or adding some type of cooling ventilation to the amp area would increase the life of these amps. I have certainly experienced amp failure in the past due to over heating and I wonder if that's what's happening to these amps.

 

cooling fan sounds like an excellent idea... as it drive so many speakers an has a very small footprint.. that means it has little surface area for heat to dissipation.. an trunks tend to stay warmer longer..

 

Are you talking about in an LX ? I have an '01 GS430... 8 speakers, total. My amp is not turning on, when I first turn the car on... then after about 5 mins, the music will start playing (Nav voice works fine- all the time though)
It's driving me crazy!!!

NOW, it started popping and crackling.. almost like it has a bad connection, but I'm pretty sure it's INTERNAL, in the ML amp...

I'm going to call this United Radio and see what they think it might be.

Also- I know the '02-'05 (ALL "OTHER" years of my body style GS) use a different part # Mark Levinson amp. Go figure.. '01's are the most unreliable, I'm pretty sure.
