well alpine has this new component kit thats like 300watts. but the speaker is 6 3/4" will it fit? i also heard that i could fit 8" subs in there to if i custom fitted them to the tower.. is this true?? thanks

I have fit 8" subs in the towers with some modifcation, however even with tuned porting there is insuffcient airspace to allow them to perform even half as good as the could. At one point I even used some $200 each@cost Scan Speaks 8" woofers designed to work in that little air space volumn, and fiberglass sealed the whole thing with little luck.

You would be much better off use a 6 1/2" - 7" midbass speaker like from Alpine, MBquart, or JL audio that would actually work in .25 sqFt than trying a sub woofer in there.

 

thanks ice, i apprieciate the advice.

That is from a bass stand point correct? Ideally you would want a coax back there, wouldn't you?

 

I personally don't care for highs coming from the rear like you would get with a coax, unless you are using a time delay/correction device.

When you sit listening to music in a concert hall or even from your TV, the sound is mostly coming from infront of you. Now there is some sound coming from the rear, that is reflected off the rear walls, and that sound is mostly low freq sound, as a majority of the high freq gets absorbed by the wall.

So from a purist sound POV, no you wouldn't want to use a coax in the rear.

But if you are just trying to get the most sound possible and you don't care about listening position, then yes, by all means put a coax or some other high freq creating device behind you.

 

I have 8" Pioneer 3-way coax in the rear, but i'm thinking about removing them and only use a system in front doors and a sub in the back... There is good with some kind of rear-fill in the back, but the big pioneers, even if they fit perfectly (actually the tower in my car is exactly MADE for 8" speaker it looks like!) but they are not to its justice there without any room for the bass to play in, so its mostly a lot of treble coming from the rear. I have more base in my front system!

BTW, I have a S5 european sold, but i dont think its so much difference.
