Ok, right now I have some MB Quart 10's in my g/f's car, but come Tuesday I got her two 15's that I'm gonna replace the 10's with.

Ok, here's the amp she's using:

Here's the subs that are going in it:

First, I know the amp is a 4 channel amp, but that's beside the point, it's what I'm using for this. So, since the subs are 4 ohms, and the amp is stable at 2 ohms in 2 channel, so from what I understand, I should wire the subs up in parallel mode? Cause what I've read is that if they're parallel, the resistance will be halfed, so they'll in reality be 2 ohms when wired up that way instead of series mode? (remember I know SQUAT about car audio)

Also, how should I wire up the amp? This stuff is already wired up w/ the two 10's, but I got that installed at Circuit City and I don't know what the guy did. I was planning on just cloning the way he wired it with the new subs, do you think that'd be ok?

If anyone might be able to do a quick wiring diagram w/ that amp and the subs that I should use I'd GREATLY appreciate it, or if you could tell me some stuff to do, etc. Or if I should just clone the current wiring.

Oh, and I don't even know exactly what "bridging" an amplifier means, lol. (as you can tell I've never messed w/ audio stuff) so if you say I should bridge this and that please make a quick diagram for me in paint or somethin Or provide a good explanation.

 

i thin your right on wirein them parell i know jack bout oms but as for wireing the amp its realy easy just take the wires from the old amp and put them in the new one + to + - to - and rem to rem

 

Ok. That amp is 2 ohm stable, but only in stereo mode. As soon as you bridge two channels together, you are in mono mode and the amp is only 4 ohm stable. So the amp is 4 ohm stable in 2 channels. Follow me?

Since your woofers have a 4 ohm impedence, I suggest bridging two channels together for each woofer. Using all 4 channels total. Follow me? Bridging an amp is easy. Just use the negative from 1 channel and the positve from the second channel. Then run a little jumper wire from the remaining positive and negative terminals. Got it? If not, just lemme know.

 

Simply put.

1 sub bridged on front
1 sub bridged on rear

That's about it.

 

But he said that he didn't know what "bridging" meant. So I kinda had to break it down. And I have NO idea what the hell blackz is trying to say......

 

I'm with you on that. But most amps have bridging instructions with them or even on the actual amp.

 

yea i donno what i wuz tryin to say eather dont post late at nite
