install problem

[wcarson8911 10+ year member]

okay i'm trying to hook up my hifonics 1206 and my FI Q 15 D2. I hooked the amp up properly. Installed the sub and wired it in parallel. The amp lights up when i start the car so the amp is working. But i get no signal at all to the sub. What could be the problem?

First check the rca's...I don't know if your hu has a sub volume...if it does make sure it's up . Let us know after you check those out

X2, if the H/U has a sub option, make sure it's on. Double check the RCA's. Check the remote wire and make sure it's hooked up correctly.

idk what you mean by check the RCAs? they were connected to the sub output a while back and haven't been touched since, can an RCA just disconnect on their own? and the sub control is turned on the HU. The remote lead wire works because the amp lights up when i turn the car on.

maybe rca's went bad try a new pair

ill try. how likely is it for a pair of RCAs to just go bad?

had the same problem, (no mean to steal thread, or even attempt) i bought new rca's and still no fix. So I thought it might be the connection on rca (internal) so i looked and everything seems fine.

My advice, if you redo the wiring, check it all, and no fix, go to a local shop that does amp repair, or buy a new amp.//content.invisioncic.com/y282845/emoticons/blackeye.gif.66a1670f5aaf7f406e783a63e3387dc5.gif

could it be the sub?

 

[LowEndTheory 10+ year member]

any luck? The sub was good when i shipped it. Working until the day I took it out to send it to you. Do you have a multimeter to measure if it reading anything at the terminals?

 

[wcarson8911 10+ year member]

how would i use the multi meter on the terminals?

 

[LowEndTheory 10+ year member]

Measure the voltage at at the speaker terminals of the amplifier to make sure it is getting a signal.

 

[wcarson8911 10+ year member]

what should the voltage read?

 

[Worlddre 5,000+ posts]

put your meter on the terminals and read what it says...then turn the radio up and down (using a test tone if available but not required) the voltage should go up and down with the radio

you should put your rcas into your input instead of output on the amp lmao

jk, what kind of rca's are they? Stinger has a had loads of problems w/ their rca's lately. Try buying a very cheap set of rca's if they are stinger and run those instead. If the cheap ones work, you know your problem. if not then the only possible sitiuation is that the rca connect on ur amp is bAd. That's if you've ran those rca's on a system before. Have you?
