more audio trouble !!!!

ramhunter9 · Jul 20, 2010

just got in the new kicker 400.1 amp , hooked it to the rockford P3 i got from JJ and the sub went poo on me i guess . It pops when it hits .....so back to the drawing board .

amp is a 1 channel kicker 400.1 class D

what sub in a 12 should i get ?? can i run a 4 ohm sub again ? or with this amp do i only run 2ohm ??

I have all polk DB audio in the doors and love them thinking of the polk MM in a 12 . but its 4 ohm DVC ? will that work ??

here is the sub ....

sent you a PM bud, somethings not right here. Obviously the stupid thing shouldn't be popping - but I can't figure why it would either.

Check the things I shot over in PM - lets go from there.

all is wired up correctly .... called crutchfield they said its a 2 ohm speaker and that amp needs a 4 ohm dvc converted to 2 ohm ? im so lost

do you have a multimeter? I really wonder what load the amp is seeing from the sub.

Its a dual 4ohm sub, meaning it can be wired to "show" a final ohm load of 2 or 8.

no big JJ .. it was only 50 bucks pal .

before it popped it was kicking the protection on and off, on the amp.

i wired it up like the diagram ... i dunno live and learn .

i them put in a single voice coil sub on it and it was fine amp ran good on the ****** speaker i had layin around .

will that polk sub at 4 ohm work on my amp ? do i wire it for 2 ohm again ??

it kicked the protection on and off on the amp? Now you REALLY have me wondering........

The polk will work, wire it up like this (same as the one today):

ramhunter9 · Jul 20, 2010

yup ..thats correct .... any one want a fancy paper weight ??

im putting 120v threw her as she sounds like pop corn ...i will see how far the coil will fly

What are the specs for your box (mounting depth and volume), and how much do you want to spend on a sub.

With these, we can give you some suggestions that will work well with the amp you have.

oh man that sucks. Where did you have the crossover, bass boost, and gain set?

ramhunter9 · Jul 20, 2010

all set half way ....no way that came into play ..

box is .88 cu ft

.88 cu ft sealed?
Do you know what your max mounting depth is for the box?

ramhunter9 · Jul 20, 2010

box Mounting Depth is 6.375"

ramhunter9 · Jul 20, 2010

that polk is 4. 5 /8 mount depth should fit my box

**** that sucks. I've never had to turn the bass boost up that far though...LOL

to get the most out of this amp you are still going to want either a 2ohm single voice coil sub or a 4ohm dual voice coil sub so that the amp is in 2ohm load.

stay away from shallows. find a good sub that has normal depth of 6"

ramhunter9 · Jul 20, 2010

butch , will the 4ohm polk i have listed work out ? it calls for .88 ft of air space same as my box and will fit

The polk looks like a good option. Your box having only 6.375 mounting depth is now your limiting factor on what subs you can go with. You basically need low power (small magnet) or shallow mount 12" subs. I would recommend RF, but since hat is what you just had an issue with, get the polk they make good ****.
