car amp wiring

I got a JL Audio 300/4 with four speakers 75W rms. Should I get a name brand wiring kit or are the cheap ones on eBay just as good?

I bought my wiring on ebay and have no problems
the brand of power wire isn't critical as long as you are using a sufficient gauge. I use Voodoo and I am happy with it.
Use a fused 8 gauge cable for the one amp or a 4 gauge if you plan to add a sub in the future
RCAs are important, you should get a reputable brand (I chose Monster) and run the wires on the opposite side of the car that the power wires run to minimize interference. Twisted pair helps reduce noise but costs more.
Speaker wire should be at least 16 gauge for 75 watts RMS

In order to install a car amplifier, the required materials are a power wire, a ground wire, a remote wire and an RCA signal. Locate the factory ...

i wanna put my old system into my new car but these installation people said it'd probably be better just to get a new amp wiring kit cause the wires are copper and they oxodize and stuff. but my stuff is only like 6-10 months old. should i listen to them and just buy new wiring or no?

if you want to take the time to re-use the old stuff, go for it as long as it is long enough to fit in your new vehicle. sounds like they just want to make a few extra bucks.

I have a single JL Audio 300W RMS sub and a Kenwood 300W RMS monoblock amp (KAC-8104D).
The manual of the amp says I can wire the car 2 different ways:
- Standard way of RCA and trigger cables from headunit to boot.
- It has input points that would come from your rear speakers, which hijack the signal and turn the amp on - much easier to do.

What do people recommend and why? Pros and cons of each??

Here is the pros and cons.

The "trigger" and RCA cables would get the best sound but are a little harder to install and can only be done with an aftermarket stereo and will require pulling out stereo which isnt too bad with the right tools.

"Hijacking" would be easier and you can use with factory stereo...(which if you have a vehicle with a warranty you might think about keeping.)But if you use this method it will not turn the amp on when the radio comes on so you would have to run a wire from an ignition running wire somewhere maybe the wire to the cigarette lighter. I have seen but don't recommend wire ran from fuse box.

Hi all. I have a 300 Watt amp connected to my sub in my trunk. I am now going to upgrade my car speakers. Is it worth re-routing the speaker wires back to the trunk, through the amp, and back up front? How much work would it require?

If you buy a nice 4 channel amp, and hook it to your factory speakers it will sound great. If you hook it up to aftermarket speakers, it will sound way better.
Its really simple to hook it up. All you need to do is run wires from the trunk to behind the deck as you did your RCA cables. Then you make the connection behind the dash as you did from the deck to the speakers originally. Obviously you would cut the wires from the deck to the factory wires and cap them off to prevent a short.

ok, im trying to run a small car amp off an old 12v pc power supply. the only part im having trouble with is how to acivate the remote trigger to turn on the amp.

can someone help me please??

thanks
i tried that already

its a pretty tiny amp. like 150 ish rms or so i think

Normally The wire that turns on the amp comes from the Deck.

If you do not have one, Run a small wire to it from the battery with a fuse (prolly a 5 or a 10), and install a switch in the wire to turn the amp on and off.
