so i have a 2000 base model prelude, i was taking out the back seats to make room for a seat belt harness bar, i had to relocate a sub amplifier under the drivers seat, and when doing so the positive got loose and arced with the ground to the amp, (i know i should have disconnected the anl fuse but i forgot) also i don't know the relevance but the shop that connected the system got power from the fuse box under the hood, it was connected to 100A battery connection, my problem now is that when i turn my car on the gauge cluster runs fine but when i turn the a/c on the cluster quits working, the interior lights dim and the radio cuts on and off, also i dont know if this is a coincidence but the car is over heating now, the upper radiator hose gets super hot and the lower hose stays cool, please help!

 

somebody helllppppp

 

when you say "was connected" to 100A battery, that means it's not hooked up anymore?

i would check to make sure all hot wires going to your sub are insulated properly. that is an odd thing to make the car overheat, though. even with the extra pull from the a/c. i know you're in tx, but i'd go without that a/c as much as possible. sweat now instead of sweating over the money you're going to have to drop to fix something else.

 

i d/c the wire so it would stop any current running to the amp to see if that would fix the problem, Texas summers are brutal bro, the car was running awesome before this little mix up, is the upper hose supposed to be running hotter than the lower?

 

yes. that hose is always going to be hotter at operating temp. don't worry about it.

i definitely think you have a short somewhere. trace all your wires(for the sub), twice, and then have someone else check. i'd pull your radio and check your leads there, too.

 

ok so was researching other 5th gen electrical problems and one person said it was their ECM fuse so i changed mine and just to see what would happen i left it out and started my car, correct me if im wrong but a car shouldnt start without the ECU fuse, or should it? i also D/c the radio well i pulled the power from it and the fuse and still having the same problem, i also d/c all the power coming from the sub amp and the mid and high amp, and still having the same problem

 

anyone?

 

I would check all the fuses. Then ask this in the audio forum, I'm sure some of the installers there deal with this.

 

thanks integra, ill re post in audio

 

would it be plausible that i fried my ecu? someone said that might be a possibility?

 

so i went with the ecu theory, and i borrowed one from a friend of mine and i installed it in the place of mine so i reset the ecu and the car wouldn't turn over so i plugged the one that i thought was fried and what do you know? running like a champ again, does anyone know why this would happen? was there a loose ground on the ecu? thanks for your help

 

that is odd. i'm glad you got it worked out. i've had odd problems that somehow got worked out when working on computers. i'll commit your fix to memory

 

that's highly possible.. may have the same problem with my ef..

 

thanks to everyone who helped out, after having my car down for two weeks and searching every wire from all the fuse boxes and relays i finally found the problem, turned out to be a loose ground wire, on the negative connection to the frame of the car was loose, thanks again for the help
