Subwoofer preamp vs rear/sub preamp.


Recommended Posts

I'm looking at headunits and I'm wondering what the difference is between having a dedicated subwoofer preamp output vs having one with a low-pass filter and sub level control? Is there more flexibility with the subwoofer preamp?

what stereo are you looking at?

That's why they don't deliver.

Yer ass better go sit along the side of the road and wait.

You can't expect them to travel up some dirt road in a hick / back woods town. Thats how horror movies start :D

I explain things very simply and use analogies in terms of Pickles, and grape drink, pool noodles and jackhammers...if you can't put 2 and 2 together there man, There simply is not much more I can do.

The Subwoofer Output doesnt fade front to back, the Rear/Sub Output will...

Some radios do not have a dedicated sub output but the rear can be switched to a sub out. My Sony does this. I can go into the menu and either choose to have it as a rear channel or a sub channel, which has the option of a low-pass filter and a level control, and is non-faded.

Too many projects, too little time...

ive got the kdc-mp338 and its the same, has a front set and rear/subwoofer.. all you gotta do is in the HU change the settings to sub-w and it gives you a seperate eq, -15-+15 for bass.. check my vids in sig.. its that HU

works fine IMO and i like how it has the seperate subwoofer controls/
