Stereo Subs question
 

So have you guys run free air subs mounted down below the rear seat? How did they sound? How much power did you put to them? I've always done sealed boxes in cars, never done a fre air application and am worried about not have a good thumping bass with free air.

I put 4 - 10" subs in my back seat. I fiberglassed a board down the middle/inside to take some space out to meet sub specs. They are not totally sealed due to my seat can still come off and back side is still a storage area.
I have a Memphis 1100 class d running them. I think it would sounda little better in a car but they still thump.

I have 2 free air 10 subs mounted along the sides. No hard hitting thumping there. More of a rumble.

It depends on the sub. If they are designed as free air they will work fine. (Our free air subs are mounted in car decks)

It is like anything if it is designed for it it works well, I have been doing some studies with boxless subs.

Do you have the Teil/small specs on the subs?

I was looking at the Alpine SWR-M100 10" subs... designed for free air apps. I have a 900w amp that I want to run two subs and these will take 300w rms. I can turn the gain down on the amp, so power will not be an issue.

I just bought a pair of them, but have not installed them yet. They are rated for more watts than any other free air, so hopefully they sound good.

I just bought the same Alpine sub. I installed one & it's all I need. I also installed an Alpine amp but forget the specs. The amp was around $400 alone. Check out a shop on ebay called "yougotadeal". The sub was $100 less than anywhere on the internet & I received it in two days. Let me know if you need more info on them.

Thats good to hear. I'm gonna put about 250 watts a piece to them through a pdx amp. I got mine off ebay as well for about $250 for the pair.

Thanks guys, I didnt even think about ebay. Well then I am gonna give them a shot. I'll update the board once I get them installed.

If you get the calculations correct on a free air sub, they will be just as affective as a port or sealed box
