I know; sorry guys.  I was getting one of those I feel like I'm the funniest guys in the world kind of buzz.  Almost like acid

Did anyone else notice there were 19 people viewing this thread about an hour ago? - we have visitors! Im so proud! my second thread!(sniff) haha anyway,

Buzzed members aside, whats the advantage of a 3" coil vs a 2.5" coil on 1000 watts?

would a ssa icon or incriminator death Row produce a noticeable amount more output than an sa-12 on the same amp in a 1.5 cubic foot (NET for sa-12) ported box tuned to 32 hz?

lmao no idea what this thread is about but that was funny

Whats the advantage of a 3" coil vs a 2.5" coil on 1000 watts?

would a SSA Icon or Incriminator Death Row (12") produce a noticeable amount more output than an sa-12 on the same amp in a 1.5 cubic foot (NET for SA-12) ported box tuned to 32 hz?

a 3" coil has more potential for more power handling because it is wider and can dissipate heat considerably compared to a 2.5" application.  Physics dictate this.  the bigger the coil, the more space it takes to run optimally, normally.  an Xcon is not even in the same ballpark as SA series;  its sound quality features and design along with its high power handling make it a suspect for a high quality product. 

Two thumbs up! that was very interesting and informative reading

A little complex, but understandable - Thanks

 

BTW i didn't know that running rcas separate from power was a myth. is it really not true? i thought power wire made "noise"  - the install shop ran my rcas separate.

Power/ground doesn't matter. Now think of where your ground runs. Get it?

I didn't want to post this earlier but since I drank a few beers I guess I will.   Every vehicle is different.  Achieving a tolerable unwanted noise is a good thing.  You can try a bunch of things to reduce the noise all you want; Blah Blah.  When it comes down to it, equipment, equipment, equipment. No I didn't copy and paste.

Nope, equipment is easy. Install, install, install.

Lol "jus one mor beer brah" I have dang near the best amp and head unit that the companies that sell them make, I'm sure i can do better,

Maybe you meant to say Install, Install, install?

I said it first! ( ) haha

The ground runs near the rca's for like a foot

By the way, does a 3" coil have more motor strength than a 2.5" coil on the same power?

umm, no. Don't forget that the. WHOLE chassis is a ground. Coils don't have motor strength.

If you switched HU's then your comparison is invalid.  One of the HU's may have been more sensitive to the poor OEM ground location than the other, for example.

 

As to the 2nd question.....this has been a long thread & I don't remember, are the speakers driven by an amplifier?

Yes, the speakers are powered by an Alpine PDX-5, a Kenwood KDC 896, and the speakers are Alpine Type R components

(i faded all music to front speakers)

I'm not sure if you need  more information than that. if you need to know something more, just ask.

the amp is under the passenger seat

 

If the gain is set high it could be noise from the amp.  It could be a poor ground on the HU or amp.  Could simply be the noise floor of the equipment.  Could have the RCA's routed by something noisy inside the vehicle.  TBH if it's only a slight, low noise when the stereo is muted I wouldn't worry about it, but I don't know what the noise actually sounds like.  I guess the severity of the problem is for you to decide.

As Sean said, the entire chassis of the vehicle is the ground. 

 

As to the 2nd question, assuming everything else was equal between the coils (density, wire gauge, etc)  the 3" coil would probably have a higher motor force since there is more "L" in the "B" field.  But if everything was equal, it would probably have a higher Re as well again since there was more wire.  But it's going to depend on the specific design, "all things equal" doesn't really work with subwoofers because most of the time things aren't equal.

Depends on what bandwidth you are referring to.  Peak output around tuning would be about the same, but above tuning the Icon would have up to 2db more output.  That doesn't include power compression however.  The Icon has twice the rated power handling of the SA-12 and a 3" coil instead of a 2.5", so it's highly likely the Icon would experience less power compression at that power level, which would increase the output differential between them.

 

I didn't model the DR, didn't feel like looking up the T/S

The best way to break in a sub woofer is to simply play music on it. If you try by other methods, open air for x amount of time, or, x amount of time on x Frequency, it only breaks in at that application. Playing music, you will break in across the sub woofers playing frequency. Which is the best way to do so.
