Yes....hook one up to the left channel and one up to the right.....once everything is wired up.....keep gain down on amp and turn stereo on.....turn up stereo with amp gain down to right before high end speakers start to distort......then while its playing, turn amp gain up about 1/2 way. close your trunk and hop in drivers seat....sound gd????? You might have to adjust level on amp and bass on head unit to taste.....Be careful though....pioneer subs are only rated around 300 watts continuous.....dont want to blow them...gd luck....
Hello.... I am sorry to hear you are having problems. The reason for this is that since you have a stock stereo, the shop (or person) whom installed the amp and subs used a line out converter. What this part does is allows the connection of RCA cables to the factory head unit. Almost all bass signals are always in stereo, so since you were only hooking an amplifier for just subs, you can actually just connect to just one of the rear speakers instead of connecting to the right and left. Just makes the install a little quicker. There is nothing wrong with this as I usually do the same thing in our shop. However, if you are going to be using the balance control, then you will need to go back to the shop and have them hook the converter up in stereo (to both rear speakers). Hope this helps!
You will need to connect the low level input leads from the head unit to the amplifier (they are RCA cables). If there are no low level leads from the head unit, you will need to connect the wires from the speakers directly into the high level inputs using a wiring harness which should have been included with the amp. It should include a wiring diagram. You will need to use that diagram in conjunction with the truck's wiring diagram in order to know which wires to connect. They are color coded and once you have the vehicle wiring diagram (which can be downloaded by searching for it on google.com), it should be easy to determine which wires to connect.
there is probably a switch that says lpf-full-hpf those are your low pass filter(only low tones) full which is all ranges of sound and high pass filter which when you want to hook up a set of mids or highs I hope that this helps u out
Run one set of RCA lines from
head unit to amps if you only have one set of pre-outs on the head
unit, then at the amps, use an electronic crossover to split between
the two amps, and this will also allow you to control what frequencies
go to which amps/speakers. You should use one amp for the speakers and the higher power amp for the subwoofer. You should not try to connect both to the subwoofer. Use 4gauge cables if possible. If you have more questions, just ask.
