greggtr Posted August 30, 2013 Report Posted August 30, 2013 Hi Guys, I finally finished and tuned my car... Car 2003 Miata Head Parrot Asteroid Smart 3v pre-out Doors 2 x DD AT28 4 x DDAW3 2 x DD W6.5 Amp DD S4b Boot 2 x DD 9510 Amp DD M4 I LOVE the front stage, was extremely surprised how clean, clear and wholesome the front stage is.... The Subs are a let down, they are in a 2.5 cubic foot box, facing the back of the car, 2 x 4" ports 8"long , tuned to 46-47hz directly ported into the cabin. With the boot open I hit 136.2db at the dash, with the boot closed 133.4db My issue is, I feel I should be getting MUCH higher db, I am pumping around 5000w of power into 2 SPL subs in an less than optimum (but still acceptable) enclosure. before you reply.... I know convertibles are bad at db, but I like and car, so don't say "change the car" Please advise....
LT.Smoke Posted August 30, 2013 Report Posted August 30, 2013 My question is why the heck are tuned so high??

White Lightning Posted August 30, 2013 Report Posted August 30, 2013 Why are you automatically blaming your sub drivers for your problem ??? First off ... the Miatas are normally VERY small cars and mostly convertables ... not a good recommendation for a SPL vehicle ... Second ... What is your vehicle's resonance frequency ???

LT.Smoke Posted August 30, 2013 Report Posted August 30, 2013 My question is why the heck are tuned so high?? DD is optimal as higher tunes OP 133db in a convertable sounds good to me you have a cotton roof..... how much energy do you think is escaping from that? these guys deaden their roofs for a reason Right on... Well in that case OP your score isnt bad for a convertible Team MaxRetribution Si Vis Pacem Parabellum Id rather be judged by 12 than carried by 6 Bowhunting- Life Begins and Ends at Full Draw Bowhunting Team Fatal Trajectory Hunt Team http://www.stevemeadedesigns.com/board/topic/49335-sick96vtecaccords-t-line-build/?hl=sick96vtecaccord << Accord Build http://www.stevemeadedesigns.com/board/topic/68498-smokedout08impalas-tline-build/?hl=+sick96vtecaccord << Impala T-line build Rebassed.com for all your music needs 👌

The tune could be a problem as well. I'd drop the power and give them 4.5-5 cubes with plenty of port to operate efficiently. Flared ports, on both ends. Im not the one you want to try to troll. Just a fyi for you.
newschoolsoundz Posted August 30, 2013 Report Posted August 30, 2013 small cars ive always ported to the front for better scores
