little rich Posted December 28, 2007 Report Share Posted December 28, 2007 2 subs! , 1 should be good enough though should sound good enough for what you want, i recon a black carpet finish would look pretty smart, mine will hopefully be retrimed in cream leather (got to get the box made 1st lol)rich, Quote Link to comment Share on other sites More sharing options...
robgti Posted December 29, 2007 Report Share Posted December 29, 2007 Im doing mine at the mo and the box is made for sub. Then problem is i wanted sub in middle with amp either side but it wont fit, so mines going to do sub to one side and amps the other side.once ive dynomat`d the boot and sorted it out ill put pictures up and it should be all carpeted as well.

RobM Posted December 30, 2007 Report Share Posted December 30, 2007 Avoid having 6x9's and a sub sharing the same air-space. I.e. don't put them on the shelf! Reason being, the sub moves a lot of air, the speakers are trying to move in that same air, and one cancels the other out. Also, the pressure created by the sub (especially a decent setup in a tiny boot) will damage your shelf speakers over time as it will be pushing the cones with the air movement, often against the direction the 6x9's themselves are trying to move.I once (back in my ICE days) had somebody come to me with a similar setup as you propose, wondering why his nice expensive sub was sounding so poor since fitting his new shelf speakers. Simply unplugging the wires from the 6x9's made a massive difference to the bass.In a car as small as the Lupo, a good set of front speakers and a sub will be more than enough to sound superb!

EaRNi! Posted December 30, 2007 Author Report Share Posted December 30, 2007 already got 6x9s in the shelf, would you take them out? Quote Link to comment Share on other sites More sharing options...
RobM Posted December 31, 2007 Report Share Posted December 31, 2007 already got 6x9s in the shelf, would you take them out?Experiment, but ultimately, yes Get the sub and amp in and working, but disconnect the 6x9's while you're doing it. Get it working, setup and tested without the 6x9's and see how it sounds. Also, just for a laugh, watch what happens to your 6x9's when your sub is going full tilt and the speakers aren't plugged in. I'd betcha you'll see the cones moving around a lot still!Once the sub is working plug the 6x9's back in and have a listen to a few different tracks. You may decide you love it and want to keep them, you may also decide that the bass sounded better without them. ICE is very much a personal choice, but just be aware that even if you like the sound, your speakers will still be taking a battering Quote Link to comment Share on other sites More sharing options...
