How can you tell if a Fiero has a factory Sub? Where are they located?

Under the dash on the passenger side. It should be in an enclosure. And if you look at your map lights and it says "Performance Sound" with a slider switch, you have the factory performance sound system



That big black enclosure is what the sub is in.

If the radio has been changed does it kill the sub? This car does have the Switch in the map lights. Can the sub be replaced with (size)?

I'm not really strong on audio, so I'm not sure about your first question. You can always use the "Search" button at the top of the screen to do a little research.

And for sub replacements, see here and scroll down until the OP talks about the subwoofer in the first post.

5.25" sub size, but some have mdified it to except a 6.5". Yes, if they didn't "wire" it up right a aftermarket headunit will disable the factory sub. In all actuallity the factory sub isn't all that great along with the amp that pushes it not being all that great either. If I remember correctly the amp uses a integrated IC for amplification, which is just about the lowest quality you can get and not much "real" power unless you go with a really big one like is used from time to time in cheaper amplifiers like Pyramid. I think it only put out something like 20 watts, which isn't much for powering a replacement. Since you have an aftermarket unit, you'd be better off getting a littel 100 watt amp and upgrading the sub in the factory enclosure to a 6.5".

The factory sub needs some wiring modification to work with an aftermarket radio. The sub isn't going to knock your socks off but does add a dimension of bass to the stock sound system.

If I hadn't purchased Rodney's replacement sub, I think I would have refoamed the original unit. The stock material was completely rotted out, but replacing the surrounding foam is a fairly easy job. Of course, that's if there are no further problems with the stock subwoofer.

heres an article that may help---you need to cut and splice 2 wires in your wiring adapter
