Sub tear down

[ramthis9501]

Yup you read it right, think my sub is in need of repair. It cut out again yesterday and a new fuse didn't fix it this time. Had a friend come look at it and he said the amp is going into "safety" mode. Thinking that there's a wire in there somewhere that came loose that just needs to be soldered back. So anyone ever rip apart their sub and/or amp before?

If your amp is clipping why are you wanting to tear the sub apart?

[ramthis9501]

The amp is built into the sub, it's an infinity basslink.

no offense but this is way above your head ... you can't just look into an amp and see what's wrong 9 times out of 10 ... you're having an issue finding a possible blown fuse for your headlight cluster i would say it's safe to say you shouldn't be tearing into an amplifier i have VERY extensive knowledge of car audio and electrical circuits and it's not as easy as "a wire came un-done and has to be re-soldered on" ... VERY rarely is it something so simple

Well I'm going to have Mike there to help me, I don't trust myself alone with this kind of stuff yet

[ramthis9501]

So I found some info on the sub, one case was the mosfet went out. Think that might be one reason? If so is it replaceable or repairable? Me and Mike are going to rip it apart later so I'll let you all know how it goes and post some pics

[Matt]

a mosfet is a transistor on the amp not the sub ... sometimes they look blown up sometimes they don't ... you'll have to take the old one off get some thermal grease to re-apply it to the heat sink and solder it in .... rarely do amps blow up the same so googling what's wrong with my amp will get you many answers ... that's like asking someone who has never seen your truck why the engine blew ...

Well we tried it and couldn't even get it apart. It started cracking in places. So guess I'm just gonna have to go without it. Might see if I can find something better later

no the housing was cracked all the way around the screw holes making me leery about prying it apart. if it were mine i would have continued for the sake of ripping shit apart but it isnt. plus side colton those infinity basslinks are on amazon for 184 shipped brand new. chrissy is having me order and install one in the tahoe after we get back from florida. i am going to tap into the factory bose system and make a custom panel with quick connects so we can remove it easily when we need the cargo space

[Matt]

just fyi .. you can make your own assumptions on them but i installed for 5 years and put tons in bc they were super cheap and had a TON of failures with them ...
