i just added my system to my car, now the REM wire you splice off the cd players power wire correct? If not what wire do u splice it off of. next i have a 300x4 channel amp.....where do you plug the rca cables. the front input or the rear input? i'm trying to figure out why im getting no power from my amps, the power wire has power but the amps will not turn on.......the cd player is working also.

 

you have to run a remote wire from the back of the deck to the remote terminal on the amp, this is usually orange or blue and will be marekd remote or power antenna and only gets power when the deck is turned on. and the rca should goto sub out on the back of the deck

 

i have the rca cable on the right output on the deck i need to know where to plug it in on the amp

 

on the input side of the amp

 

no **** haha. the 500x1 amp has the input. the 300x4 amp is the jl audio amp. it does not have 1 input. it has a set of input thats says front speaker input and it has a set of inputs that says rear speaker input. and i did the rem wire and im still getting no power to my amps or cap. the vol meter on the power line says theres power but it wont reach the cap

 

You don't splice any wire for the remote lead, your cd player should have a dedicated remote wire. What cd player do you have?

Being that you're trying to wire up a 4ch amp I think it would be safe to assume you're running the front and rear interior speakers, which means you'd have to provide signal via rca's to both front and rear inputs on the amp. I'm hoping your deck has 3 sets of rca's, but if it doesn't then you'll have to get two Y adapters for the rca's so you could essentially split the "front" rca's into two sets. You'd plug each adapter into the end of the rca cord that plugs into the amp so you can end up with 4 plugs instead of two. I don't necessarily like doing it this way cause you're halving the voltage of the rca's on that output which means the amp is gonna have to work harder to accurrately reproduce the sound. But sometimes you gotta do what you gotta do, I have done this before in my old car and while it didn't sound as good as it could have, it sounded better than most.

With all that being said, that has absolutely nothing to do with your power issue on the amp. The rca's are just signal leads, you could power up an amp without them being plugged in, just don't expect any sound. So if your amp isn't powering up then the first thing I'd check is your ground, make sure it's the same size as your power lead, 12" or less in length, and connected to bare metal and secured tightly. At that point I'd use a volt meter to check for voltage at the amp. Even without the remote lead connected you should still read voltage at the amp, the remote lead just tells the amp when to turn on. Make sure your remote lead is 1.) connected to the decks remote lead output, or 2.) connected to the fuse box in a circuit that only powers up once the key is turned to the "on" position. If all checks out and it still won't power up then you can do one last thing. Check the remote lead to see if the amp simply isn't getting the signal to turn on. How? Locate the power/remote/ground input on the amp and run a jumper from the power input to the remote input. Don't **** yourself when it sparks as soon as you make that connection, it's normal. But I guess if you do things by the book them you'll have the car battery disconnected while doing this so there'll be no sparks to worry about, as you can see I don't always do things by the book. The amp should power up immediately (if your battery isn't disconnected) and will stay powered up until you disconnect the jumper. If it doesn't power up and you have full voltage measured at the amp then your amp is blown. If it does power up then you know your remote lead is the cause, find another circuit in the fuse box to tap into.

Have fun!

Couple things. 1.) If you use the "power antenna" lead for your remote line then as soon as you put in a cd the amp will shut off, it will only power up when the radio is in use.
2.) Because he's wiring up a 4ch amp I'd assume he's trying to run the interior speakers, in which case you would not want to use the sub rca's. All of the decks I've seen that have sub preouts have xover and eq tuning for the sub frequencies and I don't think you'd want to tune you

 

apparently all i needed was a 200 amp and 300 amp fuse. and the splitter for the rca cables. cost 100 bucks to find that out but now that it works it was well worth the money

 

wow 04, nice writing!


glad to hear its up and working... be sure to post some pics!

 

i got to find a camera but the w7 is an amazing sub. i got the 10 inch one and it gets every tone no problem. Shot my rearview mirror right off my car on the way to work this morning.

 

LOL

Thanks, car audio is another hobby of mine so I like sharing info on it whenever I can. I've been installing since 93
