yes. that's why amps have filters.. because not all head units have crossovers.
now if you use the filter on both the amp and head unit at the same time, the slopes are cummulative. 12dB =12dB would make a 24dB Q.

thats what I thought... see I am learning here!!!!

So yeah, I would check your settings on your jbl amp and see what you have the cross over set at, 80hz would be a good place to start at... If nothing else bridge youre component amp and cross that over at 80hz or so and see if that fixes it.... Also check your grounds....


Oh, and is your sub playing any bass at all? or is it playing bass and vocals?

i know grounds can do some messed up stuff.. but making my sub play vocals? and i tried a different amp, and it still did it... it does it even if my jbl 180.2 isnt even hooked up.. also it plays vocals and bass.

Whats your crossover set at on the 600.1?

I dont get it, you say its still playing the lows so all you have to do if figure out why its playing the highs. Even if for some reason the deck is sending a full signal through the sub channel you can still crossover your AMP at 80hz; it shouldnt play much higher than that (depending on you your crossover slope, which I think is 12db.)

So, while the deck might be a bit screwed you should be able to tell the amp via crossover to knock any higher freq the eff out.... :happy055:

I'm a little bold happy this morning, having problems sleeping and I have a crap load of stuff I have to do today starting in about 3 hours....

If you wanna drive down here we'll get you fixed.... :happy055:

Also, you got the jbl 180.2, huh? I hate you! lol, just kidding... or am I?

the LPF should be set @ 60-80Hz, 0 phase, bass boost off

ive taken the HU out and redone all the wires.. so if something was set on the hu, it would have reset itself. now onto the 600.1, everything is barely up, except the bass boost, it isnt up at all.. and yes the freq is around 80, it does it no matter what i set it too on the amp, it does it with a different amp hooked up to it.. it does it even if i hook the sub amps rca's up to the rear and front pre outs.. the cd player does it hooked up to another system.. it doesnt do it when a different cd player is hooked up.. once i get my CDT components this Wednesday, im just going to keep the sub off.. while it will suck bigtime.. i cant stand it.. if it isnt playing right, i wont play it at all.. or ill just keep the bass on the HU all the way down so there is some bass with the kick drums.. but other than that.. F it.. whenever i used to listen to rap.. i could put the bass on like -1, and people would be "godd@mn man" now.. if i wanted to do that.. id have to put it on like +6.. -1 now is now as loud as it was when it was on -6... but to top it off.. i cant find the damn receipt to the cd player!.. and im sure where i got it from will want one.. i do have the warranty paper that came with it.. so if i can do something with that, let me know.. but i think im just going to get the 880prs and just go from there..

And you are 100% sure you got the rcas in the right spot (i.e sub output)?

now onto the 600.1, everything is barely up, except the bass boost, it isnt up at all..

How did you set the gains? Via Dmm, by ear, oscilloscope?

and yes the freq is around 80, it does it no matter what i set it too on the amp, it does it with a different amp hooked up to it..

Thats wierd, the amp should cut any freq above that even if the headunit is sending it a full signal...

it does it even if i hook the sub amps rca's up to the rear and front pre outs..

Now the front and rear channels might be crossed over via the head unit hpf, which would not allow it to play any low notes... Which is why I asked if you were 100% sure you didnt have it plugged into the wrong rca output.

the cd player does it hooked up to another system..

Once again, the crossover on the amp sound zapp any unwanted freq from seeing the sub...

it doesnt do it when a different cd player is hooked up..

did you run his head unit and rcas to your amp, or did you use his amp to power your speaker?

once i get my CDT components

Rub it in a-hole....

weeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeelp.... she's fixed, says the guy at Custom Audio, where i got my HU...dumba$$es.. so i take off work early today to get squeezed in for an appointment at the car audio store i got my hu at.. dude tells me a guy that works there knows whats wrong.. i got a setting on the hu wrong.. after i assure him i dont, he says to come on down and they will look at it.. so i take off work, get the ol lady and drive 45minsto the place.. we get there.. dude checks it out.. messes with my xover on the amp, and says, "there you go" i listen to it.. sounds "fine", so sure whatever i leave.. sounds like it used too.... but it wasnt as loud as it used to be to me.. so i figure its because im used to it.. so everything is fine.. i drop the ol lady off at Wally World because she has orientation for a job interview deal there or whatever.. i come home.. and well what do we have? we have vocals from my sub still.. .. i guess the song i was playing wasnt as loud as the others or something, because it sounded alright at the shop, but its still there.. i love dumb people.. here i thought i was a retard because it was something that simple.. even though ive checked over that a million times.. and the dude has the gull to tell me its fine and it wasnt.. so either he is a f#ckin retard(which he is) or he just cant hear(which he probably cant).. so F it.. the shop said they will still warranty it, but will take about a week to get back, so i will call them tomorrow and have them send it in................ i guess.

oh and as im about to leave.. the owner comes out "want me to warranty that amp!?!?! haha"

i should have shot him in the knee and smashed his head through his shops glass door..

So is it playing the lows now?

its always played the lows, but it plays the vocals and everything else too.. like it would if an amp was set on hpf on a sub... i went to a guy here in town that is old school and is very knowledgeable, and i explained to him everything, and he said the amp should catch it and all, but i told him it doesnt, and he said its common for the preouts on Pioneers to mess up, but he said just to send it in and get it done with. so i guess i will.
