Question about Alpine Car Audio & Video

Open Question

I'm having a few issues bridging my Alpine PMX F640 to drive two front speakers.

According to the manual i take one cable of the rca lead and run a y splitter to the amp http://www.alpine-eu...PMX-F640_EN.pdf I have done this but the diagram is definately wrong. It says to enter the y splitter in a vertical pattern into one set of the inputs if i do this i only get output out of one channel. if i enter them horizontally into one of each set of inputs it plays out both speakers but the volume is lower. The speaker terminals are correct on the amp one speaker on top row of connections one on bottom row as per the diagram.

Yes you can use a y to go to all four. Or you could bridge the four speakers wires onto the two outputs for 1 channel

How do i hook my car speaker and the sub and output converter together


you splice the output converter into the stock stereo speaker wires, then run rca cables from the converter into the amplifier rca inputs. the amplifier prolly has left and right speaker leads, you will have to locate a manual, or photo of the mono bridged lead position, if it isnt labeled on the side of the amp

Nady PMX-600 powered mixer problem with no sound


Intermittence is usually an issue of a loose connection - whether it's in a cable, inside a speaker, inside the mixer, or power-related. I would check them all, starting with the audio connections.

Hi i have just bought a alpine dvd headunit the 105r and it only has 1 phono sub output and not the left and right phono output how do i connect my amp to this


it has 3 pairs of rca outputs, one pair for the front, one for the rear, and another for the subwoofer. the other sub preamp output is not needed to run to your amplifier.

For better sound quality, buy an RCA Y splitter cable (single male connection to double female connections), and run your regular pair of rca cables to the amp.

Want to bridge my alpine 3555 amp to run my sub.


I'm assuming this atleast a 2 channel amplifier all you need to do is hook the negative side of the speaker wire coming from the sub to the negative channel one. and the positive to another positive on channel 2. Should indicate on your amplifier channel one and two. most amps provide a diagram right on the amplifier over top of the speaker inputs. let me know if this helps.

I have Kicker ZX 650 4 channel amplifier and 4 DB drive PT6.2 mid range speaker. I want to hookup my speaker in 2 ohms. The operation manual for the amplifier can be used in 2 ohms. I need to know how to...


As far as I am aware you need to get 2 ohm speakers. I run a 4 ohm subwear as the Alpine Type R sub is 2 ohms. I'm not 100% on this though but you may get around it by bridging your speakers by connecting both speakers to the amp as normal but swapping the speakers negatives around! That may cause the amp to run as if only at 2 ohms. Hope this helped!

Make sure your speaker wiring does not come close to the 12v power cable running for your amplifier. If your amplifier's 12v power cable runs on the drivers side of the vehicle, run your speaker cables on the passengers side and make sure your tweeters have a high pass filter to stop any pickup of engine sound (When you are driving you *WILL* notice it at high RPM. a HPF (High Pass Filter) will also stop those nasty hissing sounds on S's.

I hooked up a 4 ch alpine amp MRP-F600. The back speakers play nice but the front speakers play very low. What could be the Problem?


1)When you connected the amp to the head unit, did you run two pairs of RCA cables for front and rear reference or did you only run one set of RCA cables from the rear out to the amp?  2)If that's not the case and you did ran two sets, on your amp, swop the rear and front RCA cables. If the rears go quiet and the fronts are loud you now know the issue is either in the cables or how the head unit is set up. If the fronts are still quiet, check your Amp's gain, frequency and filter setter settings (if available). If those settings don't change anything you may have a faulty amp. 3)Check speaker connections, seems trivial, but you never know.
Message me back if nothing works and/or you get stuck.

How to wire a stereo system


Connect the 2 gage to the battery thru at least s 50 amp fuse, then connect the capacitor in line before the amps. Then run the 2 gage to a connector/splitter block and run 4 gage leads to each amp. You also will need at least 4 gage ground leads from each amp to a body grounded bolt or screw. You need to run a quality set of speaker leads from the head unit to the amps. The speakers will need separate leads from the amp to each speaker.You will need to try some different combinations to get the sound and bass you want. You want to be able to fade from front to rear and control everything thru the head unit.
Use a hole saw to cut a 2 to 3 inch diameter hole in the side of the speaker box for a port to get a better punch from the sub.
Hope this helps some....
