as the title says...whenever the bass was going to hit, my headunit would jus turn off and turn on.

sony headunit if that helps. drove around fora long time today, when i came home and checked the amp, it was hotter than usuall...jl amp. ...anyone got any ideas?

Very first thing to always check is your ground!

^x2 sounds like a voltage drop is causing the amp to pull more current which then in turns causes the voltage to dip down even further.

yeah once voltage dips below 11.8 many HUs shut down to protect themselves

I don't know about 11.8, but below 10 yeah

uh ok, and how am i going to check this?

By the time mine hits 11.8 my HU shuts off and voltage jumps back to 13+ so I don't know the ACTUAL voltage it shuts off at. But anything below the high part of 11v is bad anyway. That means the battery is outputting a lot of current (since a battery is a real voltage source, not ideal, the voltage drops as more and more current is outputted [you may know this already]). So when you are dipping below 11.8, 11.7 the battery is really putting out more current than it should. That means you have way too much electrical crap running lol.

So anyway back on topic: my gauge in my car doesnt show instantaneous voltage and I am not magical so I have no way of telling exactly where it shuts off. All I know is under 12v its getting close to shutting off.

...hey i got it new for 30bux lol

anyway.....only thing i have running in my car is the SYSTEM alone...its just 12" jl sub witha jl amp....i think i kno what the problem is, it's a 7thgen civic....man everything is wrong with these damn cars. from tranny to electrical. Today it was fine tho, i was bumping it and it was perfect

well gearbox every now and then my alpine cda 9851 will shut off during a really massive bass hit.

 
Rep Power: 812

yea if thats happening, it means you are draining too much total voltage and the deck does not have enough to work properly. Its a safety thing because running a deck at low wattage will kill it. In other words, get a better alternator or turn down the bass

I wouldn't blame it on the car. try blaming it on the pos hu you have there. Sony = ghey.
BTW, my cd player did that too, fixed the problem by hooking it up directly to the battery. Just get a 12ga wire and do that.

um your saying run my headunit directly to the battery? so it doesnt even turn off till i hold the off button?.....had it set up like that before when NOONE seem to know that the fawking fuse was blown...so i ran it from my battery.

 
Rep Power: 812

well no all you are doing is connecting the yellow battery wire directly to the battery instead of to the harness. same with the black wire, attach to a ground instead of using the factory harness wire. It will work same as before. I need to do this but been lazy and I don't play music loud enough anyway.

eh im not gna do anything to this car...waste of $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$, going to save all my mula and geta custom system installed in the rsx/s.

thats the spirit lol

It will hardly cost you anything. Just get a fuse, and a 12ga wire...what's the big deal. It won't turn off on you, I'll bet on it 50 cents...hehe

a fuse for what? 12ga wire? vat the fawk?


throw some links at me lol i have no idea wtf you jus said

 
Rep Power: 812

go into radio shack they'll tell you what fuse for whatever you're doing. or your deck should have a fuse on the + battery too so reuse the same one.
