jeep keeps popping radios

So my 87 wrangler has had 3 radios go through it. Its getting very expensive and aggravating, So here's what happens. I get a radio use it for awhile and one day it just stops working. I have a full blown sound system with subs and a kenwood 450 amp. Just trying to see what everyone thinks. Thanks

Did you wire it yourself or did a shop wire it up for you? If you've gone threw that many stereo's you have a wiring issue or bad ground somewhere. Seeing that your system remote isnt hooked up I'm going to assume you installed it yourself. What I would like to know is how in the hell is a 450watt amp powering Subs and 20 speakers ? Your sound quality must be **** ! . Do yourself a favor next time you get a new head unit goto a good car audio shop not Best Buy an actual car audio shop! Have them go threw your "system" and install the headunit for you. Be prepaired to pay a few hundred dollars and be laughed at but they will know what they are doing and install it properly making sure you wont have a Car-B-Que

I never had any issues with any of the systems I've installed quite a few and never had 1 single issue. All I use are Pioneer head units . I would always use the constant power, switched power and ground from the factory harness and I wouldn't use the other wires . I would use system remote and RCA's to the amps then the amp power kits to a capacitor then the amps I used an mono amp for the sub, and a 4ch for front/rear speakers. I would always run the Positive and negative/ground cables on opposite sides of the vehicle.

^what he said, also run your positive and RCA cables opposite each other

The easiest way I can think of to destroy a good stereo or any electronic in the car is load dumping it. Basically taking a car thats running and disconnecting and connecting the battery while a bunch of different things are running like lights, blower, radio etc.
The alternator is putting out a lot of current and the battery disconnects the current is going to go somewhere. Make sure you have the battery terminals connected solid and the ground cable is tightly connected to the chasis.

And... since it is a Jeep, that means that water will drip on the radio every time it rains, plus, small pieces of rust will drop into it every time it hits a bump since it leaked every time it rained!

A plastic shield over the radio does wonders for those problems.

^^^^^Maybe a bad cowl seal letting water pour right into the radio? A plastic shield is a good idea EABiker!

I chased all the wires, no bare spots, good grounds, the remote wasn't hooked up because the subs were out and the tape fell off...oops... and the amp only powers the 2 subs. I tested the volts at the head and when the rpms hit the shift points the volts spike to 16 so I'm gonna say its a bad voltage regulator. who knows where it is on an 87?

16 volts is a little high you should see 14.5 Vdc when running. I would double check the meter though before I did the next step. The voltage regulator for the pre OBDI(pre1991) is internally regulated(Inside the alternator). If you feel that the voltage readings are correct there is a very very cheap popular mod to upgrade the alternator to a GM CS-144. It has about 40% more capacity and you can get one from the scrap yard for $30 or $40 dollars.
