Send me a e-mail if you would I have a question for you, I can't get a e-mail to you from your profile.

 

You got IM.

 

Ok, hotmail is broke too!!!
Greg,

How are you? Just put in a new system....Pioneer deck,Precision power amp(5 channel) jl stealthbox, dynaudio 240's in front no rear's. Now for my question...

The dyn's are rated at 130 continueous and I bridged the amp and put the 4 channels to the fronts so it is getting 200 continuous, do you see this as a problem???


By the way I can't use the i for some reason.

 

I realize this question was directed to 92TB so I hope he won’t mind my stepping in here to help out. :D

It sounds like you are saying you're bridging the amp to your components? Is that what you are saying? That means you're running them mono and that is not what you want for a component set, not to mention the possible Ohm conflict with the amp. Components play stereo not mono. In order to get more power to your components, which you are correct in wanting to do this, you would need to Bi-amp them, that way you will retain your stereo signal. To do this for your 2-way 240 MKII’s you would simply run two channels of your amp to the tweets and two channels to the mids. You increase the power to the comps like you want and they play in stereo like they should.

Btw, bridging an amp is what you do for a sub. Bass is non-directional so it doesn't matter if it's stereo or mono, therefore you can bridge an amp to a sub to get that extra power to it in mono and not sacrifice the sound.

However, if you are saying that you bridged the 5th-channel of the amp to your sub and ran the other four channels stereo to the front comps (Bi-amped them) then yes, you did the right thing and should have no problems from it. That is of course if your amp is pushing the sub at the correct impedance.

Congrats on the new system. :cheers:

 

No, I don't mind at all,in fact I appreciate it. If you could drop me a e-mail I need to talk to ya.

 

Hey guys. No problemo Nomad. When he says he is bridging, you can bridge amps different ways. If you are combining the power of two channels into one, and doing this twice, in effect creating a 3 channel amp that is more powerful, then this is fine. It depends on how you input the signal. If your amp asks for one input when bridged instead of two, then you will have a stereo output. I'll explain this in more simple terms. I have two 4 channel amps. They have 4 inputs. If I switch them to a bridged configuration, channel a and b combine. The RCA goes into the channel a input. The speaker wire hooks up to channel a + and b -. It has become one channel instead of two and has one signal. I do the same for channels c and d. Now I have two channels, more powerful, and in stereo. If you do this on your 5 channel amp, and put the 5th channel to the sub, you'll be fine. You need to watch your ohms though. When you bridge, does the amp go down to 2 ohm or stay at 4? If everything is at 4, and you have more power than you should rating wise for the speakers, then just be careful of distortion. As long as things don't distort, you won't have a problem. However, if the music starts to get muddie at high levels, this is a danger sign, turn it down.

 

Yeah I realized after I wrote the post he was using the RCA's to combine the front and rear channels. That is different and should be ok he just won't be able to fade which isn't necessary since he has no rear speakers. The impedance thing is what was worrying me when he said he was bridging for more power. That's why I prefer Bi-amping; you don't mess with the original impedance using that method. Anyway, I think he understands now.

:cheers:

 

Here's the web page for the manual. I can't open it. Maybe one of you could check it to see how to wire and what power he'll make.

I agree with you on the impedance, but biamping would also mean circumventing the stock crossovers. Usually I try to avoid this when I can. :flag

 

where the link? :confused: :D

I use both active and passive xovers, besides, if it's unorthodox, I'll pretty much do it. I'm kooky that way...:lol:
