Hey there,
So all of my speakers appear to work, but I have no base. This sucks esp in a convertible. I'm not much with electronics. I am wondering if this is my amps?
Thanks

 

Is this a premium GT which system does it have?

 

It's a Mach 460 system

 

Do you have N aftermarket head unite. If so it could be wired without the adaptor. That is what is wrong with mine.

 

No it's a bone stock unit.

 

You're probably getting most of the sound you are hearing from the tweeters. They play most of the sound you hear, but the lower frequencies come from the 6x8 in the doors and side panels it could be that the stock woofers are blown, or it could be that the amps quit working for the woofers. I'd check the woofers first, but being that it is a convertible it could be moisture got to the amps.
