Hi, I would like to here opinions on Subwoofer designs, Setups, And enclosures for a Convertible to produce traveling low hertz bass with the top up and down.

I have built many design in my 98 Mustang Convertible for Soundoff Contest and have hit as high as 154.3 DB's in a Usaci competition.

This my car i have brough to the competitions

Now i am looking to build a system using the back seat or trunk or both to produce that sound quailty traveling bass, not that loud rattling bass tat you can't enjoy in the car.

has anyone done this in a convertible

If so what speakers, enclosure and postions was used.

I have thought of using a 3 high end 10" subs in the back seat in seal box facing front but don't think it will sound good with the top down

Thanks for any opinions you can provide

Well, using the back seat as an application will render you with virtually no bass reinforcement (cabin gain) when the top goes down. Even with the trunk install, the top down is a limiting factor.

I'd stick to the trunk with a driver on either side as far back as possible.

Good luck!
