Wiring 6x9's into an amp

I have two JL 6x9's in my car that i believe are like a 120 or 150 watt max. I want to run an amp on them. I have a kenwood 350W 2-channel and was wondering how to wire them up I know how to wire subs but i am wiring my subs on one amp and these speakers on the other amp. How do i do this? Pictures would be great even if it's just a sketch. thanks in advance

Find the left speaker, and find the left channel of the amp. Wire + to + and - to -. Repeat for the right side.

Obviously i know how to hook up wires to an amp. I was wondering how to hook it up with a second amp. Like can i just run my ground and 12+ to the other amp or do i need to run new grounds and 12+ and do i hook it up to the same terminals as i would the subs or do i hook them up to the crossover lines. where do i hook the speaker wires into the amp? I know where the out wires go.

Then that's what you should have asked.

Anyway, you need to determine what the maximum potential current draw will be for the two amps. This is easy. Find their fuse sizes and add. From that point you can determine what wire size you need.

For less than 45 amps, you can use 8 AWG wire. If you have between 45 and 60 amps, you can use 4 AWG. 60-90 I suggest 2 AWG and above 90, 0 AWG. These numbers are a bit different than what you'll see published here and there, but overall they're basically in the same ballpark. When in doubt, use a thicker wire.

Run 1 wire from the battery to the back of the car of this gauge. Make sure you fuse within 18" of the battery, but the shorter the better. Make the fuse the same rating as what you already figured out by adding the 2 amp fuses. Anyway, at the back of the car, use a fused power distribution bar, and run the next smaller wire size from that to each of the 2 amps. Run the same size fuse in each as what's on the amp.

Same prodecure with the grounds, minus the fuses. Run the same size wire from a nearby spot on the chassis to an unfused distribution center, then the next smaller size from that to the amps.

Remote wire can just be piggy-backed to the other amp, but if you introduce a third item you'll need to install a relay.

a distribution block looks like this...



its the thing in the middle of my two amps. (picture is kind of old my stereo doesnt quite look like that anymore. more has been added)

but thats the answer to your question

Basically they let you run just one power wire from the battery to the back, which splits off into multiple wires for more than one amp. It's easier & looks cleaner than running dedicated power wires from the battery to the back of the car.

what's the difference between the fused one and non fused one?

One has fuses, one doesn't.

Fused:

Unfused:

partsexpress.com is a great place to order from, and you're not likely to get them much cheaper anywhere else anyway. I buy all of my wiring and associated accessories (along with most of my speakerbuilding parts) from them. They're a first-class outfit.

Or even run one ground to the other grounded amp?

Yes, you can. You can run a string of pennies from your battery to the amplifier too, but ultimately there's a right way and a wrong way to do things.

Well, you've challenged everything I've said up to this point, so it's not like I'm going to try real hard to hold back the sarcasm.

Now that I've just had a fresh pot of coffee, I'll elaborate.

The half assed way that you want to do things poses a number of problems. For one, the terminals on the amps are usually only as large as they need to be, meaning that you're not going to be able to safely stuff 2 adequately sized cables into the power or ground terminals, which is necessary to daisy-chain them the way you're talking about.

Secondly, doing this sort of half-assed ground wiring, using all the same size wire, is going to result in both amps being grounded through one small wire, which isn't going to work well either.

If you're too cheap to cough up the $15 for a ground distribution block, run a separate ground from each amp to the same point on the chassis. This basically works just as well as using a ground distribution block, and it'll save you a couple bucks. Likewise, you could run separate lines from the battery to each amp, but between the cost of the wire, the extra fuse holder and the work necessary to run 2 wires, it's not worth the hassle.

Or just do it your way and invest in a good fire extinguisher. Make sure to get a Class C extinguisher designed for electrical fires.

Sorry if i don't fully understand electrical systems, still there is no reason for the sarcasm. You give TGO a bad name.

I suppose I could have been more polite, but it gets frustrating when you see the same questions over and over from newbies who haven't figured out how to click on the button. Usually I just ignore the newb questions, but for some reason I felt compelled to answer this one. Guess that'll learn me.
