My Soarer never came with a subwoofer, just has the blanking plate with the X on it. I measured it and its 8" in diameter. Does that mean I can't fit a 10" sub?

 

I don't know anything about the plate because my car came with a 10 inch sub already installed. If you are willing to modify the deck you can obviously fit a larger diameter sub in. I think the depth is generally the issue because of the gas tank. If you can find a big sub that is shallow enough, you should be good. :thumb up:

I'm no audio installer so hopefully others will chime in.

 

A dremel, an mdf ring and a shallow mount free air sub means your possibilities are vast.

 

This is what it looks like. If the deck was flat it would be no problem to cut a bigger hole, but that area is raised

 

I think the reason I'm confused and made this thread is because of this post

How did his 10" sub fit perfectly when his stock sub was 8"?

 

The listed cutout size required for that JL sub is 9" so unless the soarer and sc are different in cut out size I don't see how it would if you measured 8" diameter cutout. If you can't modify the opening gonna be stuck with finding a sub with an 8" mount hole. I could have sworn mine was 10" but it's been years since I ripped my stock stuff out and I just covered the whole. That does make me remember there was a plastic trim rim ring of sorts that was fairly tall. I remember cutting it up to make a better seal. Might have had provisions to get a larger sub mounted in it. Maybe someone has their interior out and can snap a pic.

 

I have a 90 LS400 and it came with an 8" sub stock. It has been blown since I bought the car in 2011. I'm going to install a 10" JL audio sub in its place. I am going to try just taking a 10" MDF ring to space it up an inch and size it up to 10".
