No Bass

[theset3]

I recently installed a new head unit in my '94. It has the premium 10 speaker sound system in it, and i noticed something annoying. With the new head unit in, im getting no bass, but the bass worked fine with the stock unit in. Anyone have this problem and know of the fix?

Did u install it or did u have a shop do it?

The factory amp for the sail panel subs is powered via the antenna power. On most aftermarket head units the antenna is only powered if the tuner is being used. Fix for this is to hook up the antenna lead to the switched 12v wire instead of the power antenna lead.

Thanks im gonna give that a try after work!

Could you go into more detail by what you mean for the antennae wire? I'm confused. I pulled out the head unit, and I'm not sure what 12v wire you're talking about, or how to hook one up to the antennae wire. Thanks!

Just my 2c. When i had my eclipse head unit installed in my 96 camaro. They actually bypased the factory bose sub and amp telling me that they could not run that set up with the aftermarket head unit.

Thats why i asked what i did above. Good luck.

Yeah I installd it myself. I was just hoping there was a way to keep the head unit and the sail panel speakers without buying new ones

Oh... well the sail panel speakers should not be an issue. When u said bass, i assumed u meant the hatch speaker/s.

They probably didn't know what they were doing then. The Bose setup has an amp on signal wire that needs to be hooked up. I had an aftermarket head unit in my old 96 Z28 that I wired up myself.

It was many years ago. They said they needed to bypass the amp because of the power out put from the eclipse...

Either way, that car is about making its own bass now. lol

For a 94 my understanding is that the sail panel speakers are run off of a built in amplifier in the stock head unit

Nope there should be an amp under the sail panel on the passenger side.

There is a power antenna wire in the factory adapter harness that you wire to the aftermarket head unit harness. Instead of connecting that to the head unit antenna lead, splice that in with the switched 12v wire (either the yellow or red, I can't remember which, been a while.....red I think). That way the amp will get constant power when the head unit is powered.

I hooked up the blue/white wire (power antennae wire on my Pioneer DEH-150mp) to the red wires, and it still wasn't putting bass through. Do I need to do anything else or is this a loss?
