I had a pair of them hooked up to a pair of zr360's and they couldnt come close to handling all the amp could give em.

Rabbit...for burps only... Many Many of them have blown iwth 500-600Wrms..in daily use setups..1400Wrms between 3 of them is a plenty anyhow..

ill agree 1400 is enough for him, but as far as blowing subs, i can blow a w7 with 150 watts, dont mean very much....

three things cause sub failure:

exceeding mechanical limits

exeeding thermal limits

degredation of parts (fatigue failure)


2 of these three are caused by poor installs. i only said ive heard they can take it cause a shop owner in florida told me this information. he knows his s h i t and i trust his expertise (being an alpine dealer and all)

if they could blow their subs, while others *have* given them a kilowatt, I call into question gain settings, deck settings, box design... sounds to me like a poor design.

Locally it is an Alpine dealer who has about 90+ Trophies from many years of competing around the shop.. The subs apparently are massed produced to not so exacting tolerances. Generally failure occurs with the surrounds seperating from the cones in sealed applications. Ported they don't seem to have many problems.

my guy didnt mention sealed, he said h eputs his in 1.1 cubes ported tho. so maybe thats why he didnt mention it....

Ported the shop says no prblems as of yet. Sealed though..they go pop.

1.1 cubes tuned to 29hz they bump and sound awesome..with a long 3: aeroport.

so it wasnt too much power, it was poor choice of box type then.

So the MTX Amp.. and can you design me a box? i really want to customize it into my trunk like www.mugensi00.com did to his trunk with the JLW7's... so any box help would be great.. (Drawings are always nice) [IMG]i/expressions/face-icon-small-smile.gif[/IMG]
