not sure where rds come from, but it's quite famous for local spl competition....i mean sub....for amp, seldom see it...btw, the sub forgot wat model, i think double magnet model need a very huge power to make it loud.....abd i dun think it give good sq....

i dun think this sub need 1.5 ported enclosure...the biggest is 1.2/1.3 i think....the sub are mean for hard and punchy...not for soft sub bass....

it depend on sub, do u think htis sub need so big enclosure?

i was surprised to hear u say tat...:>

every sub got it's recommended enclosure size for seal and ported. the size recoommended are for the optimum performance and harmony..if u change the size a bit then it's ok, but not make a 1.5 cu'ft sub to go to 3.0cu'ft..beside the sound will be different, the freq produce and the response of the sub will also different. and there's high chance to damage the sub if heavy load the sub

a multimeter will do...but this sub is svc so it's 4ohm..as i know rds no 2 ohm sub..

y must bridge the sub at the first place? get a proper 2ch with 150rms will solve the problem...this sub is not really got such high power rating...y? i tested b4 with this brand......

btw, if u wan to make it running 2ohm, then i got a amp tat are able to perform 2ohm bridge to recommend u...confirm can handle ur toys....

the amp spec:
120rms x 2 @4ohm
200rms x 2 @ 2ohm
380rms x1 @ 4ohm
450rmsx1 @ 2ohm

it;s like this if i remember correctly...quite weird..but stable 2ohm bridge..who care?

no matter powerful or not, ur sub will be killed if the signal clipped...

a power hungry sub will not kill the amp...only cant perform well...or the sub kill himself when the owner turn the amp gain too high...
