thanks in adv

 

You are probably overheating the amp because the sub you are running has an ohm rating is too low for it to handle. This explains why it take a little while for it to kick off. Try to get your sub up to at least 8 ohms or you really will kill your amp. The factory speaker is really high. It's between 12 and 16. Abnormal for subs and I think they do this so you will buy their parts. Same story on the 430. Just make sure your sub is at least 8 ohms and the amp should be fine.

Ebay has plenty of Lexus 6x9's for a fraction of the factory cost.

 

i checked ebay i see one guy with a 6x9 for sale i have talked to him already trying to see is that my only option.....

 

this is the stock mark lev system i havent changed anything so you saying that one of the speakers going bad right

 

Usually a shorted speaker will kill an amp.
This is what I would do first.
Confirm the speaker is bad buy testing it using a multimeter.
There are plenty of youtube videos that show you how.
Once you find the bad speaker then you will just need to replace it.

If both speakers test well then it is most probably your amp that is still bad and they did not rectify the problem. I would then send it back to the place where they fixed it .

 

If a voice coil get out of alignment (which can be cause by several things) or a cone surround tears, the amp doesn't know anything about that and will keep playing merrily on (albeit with distortion from the offending speaker). Unfortunately, people use the term "blown speaker" out of context all the time. If a short develops in the speaker, the amp will shut down. But this is only one possible cause of a distorted speaker.

Replace the speaker with one from e-Bay. Just make sure the speaker is securely fastened to the door casing (ie is not loose) first.
