SQ Ideas in new car Cadillac STS

[RetroAudioinc 5,000+ posts]

I got a new car it's a 1999 Cadillac STS I wanting to do a system in it. Something that sounds good..

It don't sound bad right now but it's stock. LoL

This is what the car has...

Dash 3.5 ( I think 2 )

Front Doors 6.5

Rear Doors 6.5

Sub 12.5 ( I have no idea where this is maybe in the rear deck.. LoL )

Wanting to replace all of them, remove the sub and put a small 10" or 12" sub in the trunk in a seal box.

So just looking for some ideas on speakers and a good sub for sealed and maybe some amp ideas.

Is it easy to swap head unit out or is it one of the pita cadi's?

Also for the dash run tweeters in there. I know reflecting off the glass isn't ideal for tweeters but its not going to be an sq car I assume so just tame the upper end and that should be fine. Also I would run ID xs comps however I'm obviously a little biased if you look at my Sig.

How loud are you wanting the sub to be? If you just want some detailed low end maybe run ib in the rear deck like factory?

how much trunk are you willing to give up?

My 98 Deville is one of those PITA caddies, not sure if the 99 STS is or not, unhook your factory radio from the harness and see if your car starts to do weird things in the following few days.

PITA caddies are not fun.

It came with with a pioneer h/u so that's not an issue I pulled it out yesterday. All looks normal, it did blow a fuse on the h/u but I think the gf was just turning it up to much. LoL
