Not a relay, but a line level converter. You can get one at any place that installs car radios. You tap off your speaker wires and it brings the level down to the proper level for input to an amplifier. It has no appreciable drain on your speaker output so you would not even notice any drop in volume from the radio to the speakers it drives.

Let me know if you need any more help, and a FixYa! rating would be appreciated.

Thanks,
Dave

How do i hook up a amp to my subs in a 2004 lincoln navagator


Guessing its the factory deck and it does not have rca outputs behind the deck .You get an adapter from speaker wires to rca with the gain setting on it from a car audio shop ,wire up you amplifier and connect the speaker wires to rca adapter from the closest speaker wires to the amplifier placement leaving the car speaker still connected though ( just tap into the speaker wires ) .Connect the rca from amp to adapter and set the gains on the adapter and you ready to play .

I have a clarion m 309 radio and I'm trying to hook up a fusion FM 402 amp for a sub woofer. I had all speakers playing but, I could not control the volume of the sub with the radio. I need to know...


Amps usually receive their signal through RCA wires. Your radio should have one pair of RCA outputs on the back. (red and white) You will adjust your subwoofer volume by adjusting the gains on the amplifer (little knob next to the RCA inputs of the amp), then you can turn up the bass on your radio.

You will have to pull out the head unit and see if there is a blue remote wire for am and rca audio output jacks that go to amp. I highly doubt it. Usually you have to get an aftermarket deck

I want to hook up subs and a amp in a 2008 saturn vue how do i do it


If you are planning on using the factory stereo you will need a line level converter. You basically connect two of your speaker channels to the line level converter. That in turn will give you a line level out (RCA cables) That line level out can be fed to a two channel amp which would be where your subs would hook up to. If you do this however you will lose two channels of mid range and highs ( your rear speakers ). Downfall to this approach is that some line level converters are susceptible to alternator noise.

If you have an aftermarket deck this will be much more simple. You simply run your RCA outputs from your deck to your external amplifier. Aftermarket decks typically have front rear and subwoofer outputs. That means you can drive a four channel amp for your front and rear and a two channel amp for your subwoofer. This is the recommended way to go.
For hookups I just suggest buying an amp kit that is comparable in power rating to your amp. If you buy a 500watt amp make sure your wiring kit can handle at least 500 watts.

You will need a line level converter for starters (takes speaker level signal and converts it to line level/RCA signal) you connect this to the speaker left/right wires and it has a RCA left right on other end to connect and run to your amps, (you need this box because factory radios don't have RCA outputs on them) At that point all you have to do next is run the power/gnd/rem for your amp and then speaker wires to your front/rear speaker and then sub (if using). You can use one of these converters for your front/back speakers so you will still have use of your front/back/left/right fading options. make sure you disconnect th factory plug/harness at each speaker since the amp will be powering them and you will run speaker wires to each speaker. If you only want one converter it will be on your front channel and your sub will be power by the front. (you will fade to front for more/less sub bass unless your amp has a separate volume/bass control). If you want your sub to fade with rear speakers you will need to install another converter off of the rear speakers. Found a site with some photos that may help you with your project.

I just got the Kenwood Sub KSC WA100 from my cousin with no electric wires or nothing so pretty much what all do i need and where can i find it i will be putting it in a 07 nissan sentra 2.0


Subs are subs, they come with no wiring. You need an amp and all necessary wiring to get it bumping. What type of deck do you have? Where will the sub be placed? In the trunk? Amp install is easy. Also suggest purchasing one of those amp kits for $20-$30, makes it a bit easier.

I have a kenwood head unit with 3 rca outputs,front,rear and sub.my crossover is a kicker kx3 and it only has front and rear in and front,rear and sub out.my question is how do i hook up the crossover...


No. I would recomend running front and rear to the crossover. Use the sub out on the deck so you have total control of subwoofer output at your fingertips. Your deck should have at LEAST an 80hz crossover built in. Any further fine tuning can be done at the sub amp.
