So the standard hi-fi has a 4 Ohm midrange and 4 Ohm tweeter on each corners. Can you swap out the midrange with a 2 Ohm so long as you use an aftermarket amp that supports both 2 and 4 ohms?


Incidentally, anybody here upgraded to the BSW speakers for their standard Hi-fi? Have you guys made any Ohm's measurement on them? What are their specs?

Thanks!

 

i ordered the bsw upgrade i never installed it yet but I will soon as I get other mods complete I have no idea what the specs are I kinda just bought it from what Ive read how much people love it.

I was gonna combo the bsw's with the ms8 and use an aftermarket sub and amp in my trunk I gotta imagine that will sound awesome.

 

Hi, first time poster to here.

I was just looking to get this system and want to know if its good or not.

Seems to be from what I have seen.


Any users of it on here?

 

From what I've read, it's only worth it if you already have the Logic 7 system or already have upgraded the amplifiers on a basic stereo system.

Right now I'm in the process of installing a JBL MS-8.

 

The speakers are all 4 ohms but because the mid and tweeters are connected in parallel it gives a 2 ohm load on the amp/hu.

 

I was curious about this...I bought a stock center channel speaker and measured it by itself (no tweeter) at 2.1 Ohm.

 

Correct because all the outputs on the car are 2 ohms. So centre is run on its own, the doors are run in parallel, the subs are run on its own. The ones that run on their own will be 2 ohms, those in parallel are 4 ohms each.

 

Mids are 2ohms in the Logic7. The tweeter -although connected in parallel with the mid- has a cap inline so the total impedance is kept at 2ohms from the point of view of the OEM amp output.

 

Actually, according to realoem.com, all midrange speakers on the L7 are the same as the center speaker (2 Ohm).

Is it possible to mix L7 2 Ohm mids with standard 4 Ohm tweeters?
