Factory Speaker Impedance

Alpine System. I was messing around with my meter and decided to check the resistance value. Here is what I got.
Center speaker appears to be 2 ohm ( 2.1 )
Front 6x9's tested at 2 ohm (2.1 )
Front Tweeter tested at 6 ohm ( 6.1 )
Factory Sub tested at Dual 2 ohm ( 2.2 )

Re: Factory Speaker Impedance

Good info to know here. So if anyone wanted to simply swap out speakers, aftermarket speakers are 4 ohm. In a sense, you would be cutting the watts in half I believe.

Re: Factory Speaker Impedance

Yes, unless the amp is rated the same 2ohm or 4ohm. I'm guessing that the amp is not.

Re: Factory Speaker Impedance

I doubt it.

I have a question on the subwoofer. What does dual 2 ohm actually mean? Could you replace it with a 4 ohm sub?

Re: Factory Speaker Impedance

Dual 2ohm means it has two sets of positive and negative to the voice coil. When ran in parallel it would be at 1ohm. Yes, a single 4ohm would work as that's what I installed the first round ( JL Audio W3v.3 ). I would look for DVC 2ohm or DVC 4ohm. The factory enclosure is a joke...so if you use it, you will need to stiffen it up. I used several...several layers of bedliner spray.

Re: Factory Speaker Impedance

I actually like my factory Alpine system. I think my sub has quite a bit of bass. I actually had to turn the bass down -3 in the factory EQ settings. This is with the 430N. Now my friend has the 730N. We did a side by side comparison and his bass was non-existent. How can two factory systems be so different?

Re: Factory Speaker Impedance

Here is a really good read. Stephen is a good dude, but doesn't have much of a personality.

Probably in the settings. I've noticed that if you fade towards the front, that you will lose some bass output. I've also noticed that if you raise the Treble that it also loses some bass output. Probably something designed into the amps. My guess is that it pulls the bass region from the rear channels of the factory head unit. As you fade it towards the front you lose output to the rears which affects the sub. Just guessing though.

Re: Factory Speaker Impedance

The factory Alpine system is decent considering. If I decide to go all out, I'm keeping the head unit and using a processor ( Audison BitOne, Arc Audio PS8, Rockfords 3sixty.3 ) or something similar. You can then de-equalize the system and start from scratch. I've done it multiple times.....best way to IMHO. This way you won't lose any factory functionality from the system.

Re: Factory Speaker Impedance

I checked his settings. Everything was set to zero. Even if I turn his bass to max, it still doesn't compare to my sub. Maybe something is loose?

Re: Factory Speaker Impedance

Knowing Jeeps quality, probably one voice coil is not attached or they have it out of phase.
