First thing i have to say is that i am new to car stero stuff. OK now the problem. i hooked up my subs, that are in a sealed box both a shareing the same are space. I now know it is better to have them in there own air space, but i can't afford to make a new box right now. I didn't have them bridged and i noticed they sortive would hit at 2 different times. Would bridgeing them fix this or is this normal???

 

no that is not normal, and im not sure if bridging your amp would do anything...you could always try it though.

 

bridge your ampif you can and it will be stable. What ohm are you speakers?

Then hok up the + and - normal on one speaker. On the next speaker, hook it up one way, then reverse the + and - and see which way produces more sound.

you will find that one way will definetaly sound better than the other, as they will work as a team rrather than fighting each other

 

well right after i posted i ran outside and bridged them!! They got very loud! Alot more bass, almost to much, i got to turn the bass boost down! But now they are matched all the way up!!
lykan can you explain what u were talking about i don't get it?

 

o ya i got 4 ohm speakers

 

Sorry my typing is terrible.

When you hook both speakers up in parallel meaning they both hook up to one output, they will drop in ohms. Two four ohms speakers in paralell will lower the ohms to 2. You amp has double the power at 2 ohms than it does at 4. So if you you have a 100 watt amp when you run your speakers in parallel you have a 200 watt amp.

What I was saying earlier is this.

You go from the amp and hook minus to minus and plus to plus correct?

On one of the speakers reverse the plus and the minus leads and see if it sounds better or worse. One way the will complement each other. The other way they will cancell out each others sound. When you hook up the second speaker sometimes they will get quieter.. so you swap the plus and minus to fix it.

 

So don't bridge them? Just try and make them compliment each other by trying to swap negative and positve on one speaker?

 

make sure you amp can handle 2 ohms bridged and make sure your speakers are in phase which is what lykan is explaining. And having a box with the subs that share airspace is ok to do.
