Midwest Car Audio

ok i just picked up a pair of alphasonik pw815j dvc 15" subs and i was told they were blown ok fine im planning a recone with psi soft parts but upon further inspection i find that one sub was wired out of phase and they seem to work fine but only i put the dmm on them and it reads 19 ohms per coil wtf????? are they bad but wow from dual 4s to dual 19 no way







lol sorry im used to the othersites where you have to post a pic of my user name and yes the date is wrong on the camera

Sounds like the power applied to the coils when they were out of phase was enough to force the ionic properties of the coils, and changed the dcr. Impedance doesn't change when the woofer is at rest. doesn't mean they are blown, but good luck getting anything out of the amp you are using

lol naw im going to have psi recone them to d .7 and roughly look like this

right on

when all else fails.......upgrade...

been taking more measurements of the trunk and im leaning more toward a single sub setup , i figure it will be easier to tune really low

what a coincidince the 300$ car i bought 1993 mazda mx3 and the box for my 15s fits in but ill have to trim the stock rear panels to get them back in i hope it gets decent numbers has anyone seen these cars compete ? have they done well? i was hoping crx style numbers but without having to run a crx class lol

I will bet you a shiny nickel that turning that box to fire back will DRAMATICALLY increase the deebeezzzz!

it was just a test fit i just picked the car up the subs still need rebuilt. i may just build a single sub box and have a spare sub not really 100% sure which direction yet. but i dont think it would be louder but i know to the ear it will sound like it

That looks like a fun ass car to build

I would do both, subs up, port up as close to the back of the hatch as possible. Use all the space back there and make a beauty board to make sure there is no back wave
