Audio question for techs out there

[teevexj]

So I recently (yesterday) installed brand new speakers because my old ones up front were crackling. Well my problem still exists, but only at slightly higher volume. I didn't install the best quality speakers because I'm poor, but they still crackle with the volume just to cover road noise. I have a really old JVC deck and have a brand new Sony I bought for another vehicle but never used. What would the problem possibly be? Cracked wires, not enough power from the HU? I will eventually be adding a amp and 10" sub, but until then would like my sound to have decent quality. Anyone?

I'm going to say a loose connection.

Could just be distortion or you have the radio up too loud. Try playing with the EQ settings on the radio to see if that will help.

The usual suspects are stock speaker wires where they enter the doors through the rubber boot. They eventually break within the insulation.

I played with the EQ and right now I'm running it with my bass down as low as possible and its still doing it. I will check the stock wiring for cracks and replace where necessary. Once I get my sub and amp all together I will be replacing all the wiring.
But another question...what would be best, adding 6.5" to the back or keeping the 5.25 in the back and putting 6.5 up front? Since I am putting in a 10" sub I figured the 6.5 in the front would be the best.

EDIT; Just checked the wiring and it all seems in very good condition. So not sure, I'm going to install the new head unit another day and see how that goes.

My wiring looked fine, but had broken inside the insulation- resulting in intermittent function and poor sound. You will not always be able to tell just by looking whether a wire is good or not.

What speakers fit in what location depends on the year of your Jeep. The 97+ can run 6 or 6.5" speakers with little to no modification in all locations.

I guess I forgot to mention that is is an 89. So how do I fully test the wiring? Voltmeter? If so what kind of numbers should I expect if the wire is still good.

 

[RoadHog_ZA]

Go old school - pop the speaker out, connect a legnth of speaker cable from your deck/amp speaker output direct to the speaker terminals.
If you want to use a meter, disconnect the cables both ends, join them at one end and put the meter across them at the other end. You should have close to no resistance across them. You will need to wiggle them around where they pass through the rubber boot to see if there is any fluctuation in resistance as you do so - dead give away for the core having broken inside the insulation.

I'd pull the head unit and speakers and test the wires for continuity individually, while fiddling with the wiring in the boot, opening closing the doors, etc, but that works too.

What kind of head unit are you running?

 

[teevexj]

Right now a crappy old JVC that might be about 4? years old...but I have a brand new sony xlode I bought last year I'm going to switch it to.
