Wires good, Subs good,Amp works..#2?

Question

Alright, former post I didnt put enough info, I Have a 99 Intrepid and just hooked my system up. The remote wire is connected right, the RCA's are good and the Ground is effecient. The Amp Light is on so, im guessing its working, The subs arent blown but when I hook another speaker to it, STILL NO SOUND? I have no clue what the hell is going on...i think im just totally lost? Some help?.. answers much appreciated

Answer 1

Process of elimination, dude. There is many other things it could be. From what you've said, here are my recommendations:

1) Use a test light and verify that there is actually power going to your amp. There are some brands of amp that tie the amp power light to the remote turn-on, not the main power.
2) Is the gain turned all the way down on the amp? Turn it up to 50% and re-test system. If this is the problem, be sure to tune the gain before normal use as it may cause you problems later.
3) Is the amp configured properly? Is there any crossover or EQ setting that may be wrong? I've had problems with switches on amps being not fully switched on/off. You may want to cycle all of them just in case.
4) Unplug the RCA's from the head unit and brush your finger over it. The conductivity of your skin should cause the subs to crackle/bump. If there's sound, the problem is in the head unit. If there's no sound try to run a test set of RCA's outside the car, reconnect to the amp and repeat test. If there's sound. the RCA's are bad.
5) If there is no sound from the RCA test, the amp/speakers are the problem. Reconnect your test speaker and repeat the RCA brush test. No sound means bad amp.
6) If the test speaker makes noise, you could have a grounded or shorted speaker wire between the amp and sub. The amps protection circuit shuts it down when it senses the problem. Use a test meter to check for short circuits to ground and between the speaker wires. By the way, what is the resistance of the subs? Any chance the coils are melted and the wires are shorting internally? Or maybe the amp is rated for 4 Ohms minimum and the subs are wired to 2 Ohms?
7) If the problem ends up in the head unit, check all the RCA outputs for signal. Is the Fader set all the way to the front and you plugged it into the rear outputs? I am assuming that there are RCA outputs on the head unit.
8) Are you using a low-level adapter between speaker outputs to RCA jacks? Most of these have gain adjustment screws that need to be adjusted along with the amp.

You can E-mail me directly if you want.

Good Luck dude.

Answer 2

It could be tons of things man. Check to make sure you put the fuse in the power wire that runs from your battery to the amp. Check to make sure that it isn't melted or blown. If it is then your wire is touching some metal somewhere. Make sure its hooked to the + and is making good contact. It probably is, but I'm mentioning everything! Did you hook the RCAs up correctly to the amp and your head unit (CD player) There are a lot of diff. connections on head units and make sure you hook them up to the correct spot on the amp. You say the ground is good, but just make sure it has a good metal to metal contact without any paint touching that lead. I tried my best...any more info is much appreciated.

Answer 3

what color is the light that is on on your amp? What kind of head unit do you have. some models require that you turn the sub on, or the RCA's. If the light on amp is green, the problem is that your amp is not enabled, meaning there is no signal coming through your RCA's. If you have a Kenwood radio, try holding down the stick on the right side of radio. also, try using your tuner rather than Cd, perhaps you hooked the ACC wire up to the power antenna cable. just some ideas.

Best of Luck!

Answer 4

well all i can offer is 1. make sure rca's are plugged in all the way on your head unit. 2. make sure the radio doesnt have a setting for turning on and off the rca outputs.
3. check the gains on your amp and see if they are turned up.
4. make sure the rcas are plugged into the "input rcas" of your
amp

Answer 5

if the amp is connected to other speakers, does it give sounds? If not giving sound, it may mean that the amp is maybe not the type of amp that gives audio signal directly to the speaker. Maybe it's a preamp.
anyway, i had tried before, connecting a speaker without built-in amp to a amp(i don't know what's its genre), and it just doesn't gives out sound.. this it the problem i see..

hope that it helps..

Answer 6

well it sounds like u either the fuse on the cd player is blown OR the wiring for the speakers is reversed check and make sure right on right and so on...if the ground is good and the power is sufficient it has to be either of those two
