Help! Amp Problems
Hello! Well I need some help! Heres my Problem : after installing my Head unit, changing out stock speakers and still noticing it too quite I installed a multi channel amp, for speakers to get power and my subwoofer thats coming soon. Wired it all up, power is on, NO GAIN what so ever. My deck has the RCA outputs for front rear and sub, so i plugged monster cables running from them to the according on my amp, still no luck with anything, even when I move the dials for gain and freq. No change what so ever. here is my equipment.

Check RCA's.... You did run speaker wire from the 4 channel out to all of the speakers, right? Did you remember to run the remote wire from the deck to the amp? On the bottom of the deck there are switches to turn the RCA's from outputs to inputs (for Imprint) so make sure they are set correctly. Also, on the Alpines, there is a menu that you shut off the internal amp and switch to the RCA output, so make sure that is set as well

No I haven't run speaker wire to my four speakers, I will start to do that now, Also I ran the remote deck wire, so it is powering on and off, i will check the menu settings as well as the bottom of the deck for the switch's. A friend told me that if I had RCA wires that I wouldn't need to wire up the speakers but I guess he was wrong, after returning from futureshop they told me I would need to do it as well.
So if I am wiring up a speaker to each channel does that mean I will probably need another Amp if I plan to run my subwoofer ( keeping the same set up a speaker per channel? )
Thanks I will rip it all apart and reply asap

OP, this is exactly what I meant by those little switches on the bottom of the Alpine decks (head units). Also, to clarify the speaker wire situation... The signal gets processed and is outputted to the RCA outputs and the speaker wire outputs on the back of the HU. If you are using the internal amplifier in the HU, the speaker wires from the back go directly to the speakers. Most wiring harnesses you purchase will tap directly into the vehicle's factory wiring to save time. If, in your case, you decide to externally amplify (enter the 4 ch amp, stage right) the signal will need to go to the external amp first, then to the speakers. Manufacturers have been kind enough to innovate RCA connections to make that job easier. Run the RCA's from the output on the deck (head unit, HU, whatever lol) to the external amp. From the amp, the speakers are going to need a signal, because the deck's speaker wires should be capped off and not connected to anything. Run speaker wire from the amp to the speakers and you should have noise. Make sure + is connected to + and - to - for each speaker-to-amp connection, and double check that the deck's internal amp has been shut off (in the menu for the Alpine), and that the little switches on the bottom of the deck are set to output. Oh, and don't forget to crank that VOL **** all the way to the right once you're done Rock on, good luck with your install
