amp and speaker problem

[N2OInferno]

Alright, everything is wired up in my car. I don't know what's wrong, but no matter what I set the crossover at (on the amp) for my front stage, the tweeters simply will not work. They and the midbass are hooked up to the crossover correctly and I just can't figure out what is wrong with them.

Problem two comes up that I can only run one amp at a time. If I have just the sub amp, the sub works fine. If I have the sub amp and the amp for my front stage both hooked up, only the front stage works.. The power light on the sub amp comes on, shuts off, comes on, shuts off... I need help. I don't know what step to take next and it's getting dark so I'd really rather get this out of the way so I can work on other things. Thanks.

hmmm, toomany questions, too little information.

Do you have a lowpass filter on your amp going to your components perhaps? thsi would block highs before they'd have a chance to reach the speakers. Also what h/u do you have and what are the settings there? is it perhaps plugged into the aux or sub-out RCA's instead of the other ones?

Are you changing anything when you "hook up" both amps? perhasp it's simply an issue of your remote wire not supplying enough juice to switch both on. strange that it would do that, but it could happen.
be tourough and spellout as much info as you believe to be relavent, and lotsa stuff that you'd think to be extraneous, gives us alot mroe to go off of...

the amp is on high pass..

i'm running a pioneer DEH-8400MP. Nothing has been changed, so it's basically as it came out of a box, since I just reinstalled it. Now that I think of it, hell, maybe I do have the RCAs switched.. never thought of that..

i haven't changed anything when I hook both the amps up.. I can hear the sub amp clicking, like it wants to turn on, but it won't.. Sometimes the power light comes on, and it lights up, turns off, lights up, turns off, each time with a click..

I'm going to swap RCAs now and see what that does..

 

[N2OInferno]

RCAs were switched... I had them labelled wrong when I ran them.. haha.. stupid error.. components work fine now.. Now.. Still no sub amp..

Go buy a relay. Hook 85 to your remote lead, then hook 86 to ground. Wire 30 to a constant 12v source, and wire 87 to your amps turn on connections.
Some head units just can't handle many amps on their turn on lead, and different amps require more amperage to turn on.
Hope this will solve your problem.

Without any other information I would say its the turn-on lead...get a relay as stated above.

Also check your power and ground wires. how are you splitting the power wire? how are you grounding the amps? Are they grounded to the same place?

 

[N2OInferno]

i'll try the relay tomorrow. damn, i had a relay sitting around somewhere too and it disappeared. guess I'll have to go to radio shack or something tomorrow.. hmm..

ground is in the trunk near the spare.. I have a grounding block that has 8ga running from the amps, and the actual ground is 4ga.
power is 4ga from the battery back to a distribution block, then 8ga to the amps.

I'd really take a better look at youre remote wire before going the relay route. REally shouldnt' be bogging down with only 2 amps being switched from it, perhaps it's pinched or grounding out somewhere??? try just running a single wire straight form the back of your deck over the top of everyhting to one amp, then another from that to the other. and see if it still does the same, Throwing more power at it might only cause another problem if you've got something grounding out somewhere...

 

[N2OInferno]

I haven't had a chance to mess with it really since I've been having computer troubles while reconfiguring my hardware and reinstalling my OS, but I did go to Radio Shack today and pick up a 30 amp 12 volt relay. I tried running the single wire and then splitting it.. It seems to work a bit better, but the amp still won't turn on. When I mean it seems to work better, I mean that the LED is lit up until there is a bass hit, then the amp turns off again. It used to be that the LED would come on and turn off right away, over and over. So I'll try this relay thing in the morning..

 

[N2OInferno]

Alright, I ran the relay... still have the same problem.. But it's gotten worse now. I hooked up the amp for the sub by itself, and now the sub amp will turn on but every time it calls for bass, it switches off again. It's doing the same thing it did with both of them, but now all by itself.

 

[N2OInferno]

ok.. dunno what i did.. but this is what i did.. and it all works now..

first I moved the ground from the trunk to the rear seat mount. It was kinda wobbly, I thought maybe that was it. But nope, same thing. unplugged EVERYTHING from the sub amp and hooked up everything but the RCAs to it.. it powered on. good. then I hooked up the RCA's and the sub was working! Yay! So next, I went ahead and wired the remote wire FROM the sub amp to the front stage amp.. I had been doing it the other way, maybe that was it, or maybe something was loose.. either way, I don't understand what I did, which kind of irritates me, but at least it works now!

How did you have them run from one to the other?

 

[N2OInferno]

Before I was splicing it and running one spliced wire to each. Now I wired the remote wire in series.

Now I wired the remote wire in series.

I take it you connected the remote wire form the deck to one amps remote terminal then used another wire from that amps remote terminal to the other amps remote terminal? Either way should have worked.

Just a bit of electrical 101.
Thats not actualy possible. To series a connection you must have 2 poles, a positive and a negative. The remote terminal, being only a single pole, can not be seriesed. Its actualy a parallel connection.
