SC400 Stock Subwoofer Stopped Working
My 1993 SC400 subwoofer stopped working. I looked through the threads and the only explanation I could come up with is that the subwoofer has it's own amp? Is this correct? All other speakers work fine and sound great..

The info is incorrect. The subwoofer and all the speakers work off of one amplifier. Its in the trunk, under the mat, and I believe has 3 prongs goin into it. Its on the right hand side just below the cd changer, or just slightly left of it. It may have blown up, or dry rotted throught the years, or that amp is going bad. That amp plays a vital role in that Nakamachi/ Pioneer sound system. Those amps normally go bad after some time. I believe they get to hot under the liner and mat. I have replaced all of my stereo components, so if you need more info, pm me. Heres a link for the 1993 wiring for the car stereo, changer, and amp. Maybe this will help you understand more about the sound system, if you decide to rewire it.

Thanks for the information. I guess the amp has had better days. I know where I can get another amp, would it be easier to just replace it? i don't want to bass down the block, I loved the stock sound.

Do a search on the classifieds section here, Ebay, or Craigslist. Just be careful when you by used amps, there is really no way in testing them. Its just plug and play. Dont spend more than 75 bucks on one. In my opinion. I think if you rewired everything with a new head unit and speakers you will be much more pleased. Also, try removing the back seat, the top and bottom, and pulling the subwoofer out and testing with another unit or home stereo. Its a 2 ohm speaker. This way you have narrowed down wether its the sub or the amp going bad.

You couldn't be more wrong. Good job being so adamant about your incorrectness!!!
The Nakamichi system ONLY uses one single amp. A 5-channel located under the CD Changer. The Pioneer system uses 2 amps. A 4 channel located under the CD Changer used for the interior speakers AND a subwoofer amp which is located under the rear deck by the sub itself.

Why does everybody have to be such an As#$%^& on here if someones says something wrong or not exactly right?
If you read the whole thread, he didnt say which system he had. I mentioned both of them, due to him not knowing. Just trying to help someone out, instead of critizing him.

The reason some of us here get annoyed at the incorrect info is because CL has such a large database of info that there is very little new info to be found on the older models. A simple search will answer pretty much any question that can be asked. A lot of new users fail to search for answers and wrong answers only cloud the database of info.

I couldnt agree with you more about people not doing a search. When someones ask a question, I try my best to help a fellow Lexus SC member out as much as possible. Sometimes even my brain doesnt work 100% sometimes and I forget to mention things. Also, I dont know everything about the SC, thats what the forums are for. The last thing that I want is people not to respond when I need a little help. Lets focus on helping people, even if they ask a STUPID or repitive question.

I did do a search, but like mentioned before, there is so much information because the database is loaded. I've spent hours searching and I ended up finding my problem on my own (thank god). I need a new amp for the sub because I do indeed have the stock pioneer system. So hopefully this thread will help newer members. The amp is above the fuel tank inbetween the sub and rear-passenger speaker, it's about a 5X5 inch box and is painted your stock factory color. There is a pioneer label with the part number too, I believe
