So I blew my rear speaker...

[Subst4nce 10+ year member]

So last night I was trying to set the gain on my amp with a test tone... And somehow I managed to blow my rear 6x9..... In the front I have JL VR650-csi's and the rears were boston acoustics 6x9's... I think their still warrantied so I should be able to get them fixed.. But is there any other options for a rear fill besides nothing?

I have an old 2 channel Kenwood KAC-7203 that puts out 170w @ 4 ohms per channel I believe... Would I be better off hooking my front speakers up to that amp and keeping my rears low so this does not happen again? Or just get a nice 4 channel amp?

any feedback would be appreciated.. thanks.

when using tones, unhook speakers. this prevents this type shit

You were sending bass to those rears?

On here, having rear fill is a mixed bag. I personally like it, some don't. I'd get a nice 4 channel

lesson 1. unhook the battery before anything else

lesson 2. unhook speakers/subs when using test tones to set amps

This is what I've been told to. If you don't have a DMM or o-scope, and you MUST set your gains by ear, be quick about it and don't send those tones to your speakers for very long. They tend to be particularly hard on speakers, something about how regular music has rising and falling volumes to give your speakers a breather whereas when you put these flat tones through your speakers at near clipping volumes they can fry them fast.

When I did mine it was for maybe a minute and a half-2 minutes. I could swear there was a faint burning smell after I stopped but everything is still working fine right now so I'll just have to wait and see what blows and replace it.

See the problem was.. I wasn't setting the gains on my speakers i was setting it for my sub... not noticing that the bass was actually being sent through the speakers at the time too... I assume getting an amp would prevent this from happening with a Low pass filter (or HPF I always forget which one)?

thats ignorant. why use a tone without a DMM? there's no point.

setting "by ear" just means setting it while playing music IMO. tones are only used with a DMM

are your speakers amped? if so, unhook those rcas. otherwise unhook the speakers from the hu

Actually no I don't have them amped... soon I'm hoping to have them though... depending upon if i have to buy new speakers will depend on what i'm doing with my setup. But yeah I'll have to unhook them from the HU for now on until I get an amp to prevent stuff like this from happening...

This is a little misleading as the amplifier has to have a load on it to set the gains correctly.

And using a dmm to set your gains isn't really the best option anyway.

i use my ear. and you figure the load into the equation. maybe we're on different pages..

I too use my ears, with the speakers connected, obviously. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
