Default Help with the factory subs???

Does anyone know what the size of those subs is?

I could take the panels off but don't feel like going outside at this time (it’s probably close to 100 degrees out there......man I love AZ).

Anyone know of some good replacements?

I have the 5th channel of my Alpine amp running them and it puts out 300 WATTS at 4 ohms (somewhere I was told that those speakers are 2 ohms…..so it should equal more power than that). The factory ones are distorting.

Its an oversized 6.5" dual voice coil. You only have to pop the grill off to get to them...not the whole panel. JL makes some nice 6.5" subs but I havent tried them in a fbody yet.

Most of the popular car audio companies make a 6.5" midrange speaker. Checkout www.mmxpress.com

It is an oversized 6.5 or really a 6.75, but you can mkae a regular 6.5 fit. I measured my Focals to actually be 6 5/8.

damn.....firebirds get all the cool stuff <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> (jk) what is the advantage of a duel voice coil over a single?

Yea my bad. I was thinking of firebird for some reason. Regardless of what model they are junk. Guess I should have checked my own web page first lol.

But a DVC will allow you do run the speaker in different enviroments. It allows you to match the rest of your systems easier (Front and rear speakers at say 4 ohm, 8 ohm, 2 ohm).. A single DVC speaker that has both coils rated at 4 ohm can be run at 2ohm, 4 ohm or 8 ohm. Now if you have 2 DVC speakers with the coils rated at 4 ohm you can run them in 1 ohm, 2.66ohm, 4 ohm or 16 ohm..

Lets say your system is going to run at 4 ohm. You can do a few different things.

4 4ohm SVC wired in series/parallel to keep it in 4 ohm..
2 4ohm DVC wired in series/parallel to keep it in 4 ohm..
2 8ohm SVC wired in series to keep in 4 ohm
2 2ohm SVC wired in parallel to keep in 4 ohm
1 8ohm DVC wired in series
1 2ohm DVC wired in parallel

It comes down to how many speakers you want to run, how much power you plan to run to them, and the sound your looking for.

I hope that helped a little..

Parallel lowers impedance and series raises impedance. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

but will a DVC be louder than a SVC?

The only purpose for DVCs is to allow more wiring options. Indirectly, this may lead to being louder because you can send more power to the speaker by lowering the impedance. Let me try to explain.

Let's say you've got a pair of subwoofers. One is a 4 ohm SVC and the other is a 4 ohm DVC (each coil is 4 ohms). By wiring the voice coils in parallel, you can effectively make the speaker a 2 ohm speaker (or in series, an 8 ohm speaker). By presenting a 2 ohm load to, for example, a mono subwoofer amplifier, you will be able to send more power to the DVC subwoofer (coils wired in parallel) than you will be able to with a 4 ohm SVC speaker. With many high-end amplifiers, their 2 ohm output is twice or nearly twice that of their 4 ohm output. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Think of it this way, a 1 inch pipe can only flow so much water right, a 2 inch pipe will flow a lot more right? This is becuase there is less resistance and more volume of space in the 2 inch pipe.

Power to a speaker is sort of the same, when you have less resistance in ohm's it reacts as though your pipe is bigger. How ever, this doesn't mean you will have more volume. A 12 inch speaker with 1 inch of movement can only move so much air regardless of how many voice coils it has. Moving the air is what makes volume and feeling.

With that, what Blistering Z said above should make more sense. A 100 watt amp is going to be able to push a 4ohm DVC in parallel (2ohm) better than a 4 ohm SVC as there is less resistance.

I hope that made sense..
