Is the engine wine coming from the speakers or the subwoofer? Is the ground on the HU fine? If so, If you have an amp on the source of the wine, I would run a drain wire from the chassis of the radio to the chassis of the amp.

You do realize that pioneer isn't the only radio with a pico-fuse?

take an ipod or cd player and hook it to the amp directly and see if it still goes it.

is a possibility something happened with your alt, get a dmm and check the a/c ripple voltage at the battery

Any HU with a pico-fuse is a shitty design itself. They all mess up the same way.

Working at a shop, you see all the brands with pico-fuse problems come in from time to time.

Ask M.S. where the c litoris is and see what happens. I'm sure you can guess that he'd instantly do a wikipedia search and come up empty handed :-)

Not exactly correct man.
Any radio that has a pico fuse, there is the same chance of it popping. The brand does not matter at all.

The reason why pioneer's pico-fuse failure rate is so high is because they sell more radios than any other company (the same rule applies to kicker subs). Often to people that have no clue what they are doing, and that is how the fuse blows. If installed correctly, the pico-fuse will never go.

I agree, it is kind of stupid to still use a pico-fuse in radios, but some companies do not seem to realize that yet.

Alpine sells as many HUs as pioneer and you don't see them hardly ever having that problem. It is a crappy pioneer design.

Do you even know what the pico-fuse is used for and why it blows? Incorrect installation.

The way to prevent any pico-fuse problems on any radio is to install it correctly. Any radio with a pico-fuse has to be cared for when installing.

I guess noob installers will have trouble out of a pioneer radio.

Most people don't disconnect power to the electrical system when doing something as simple as connecting RCAs. I don't even.

Making that fuse so sensitive is the stupid design.

All you got to do is unplug the RCAs, then unplug the radio. It is not that hard. When installing, just make sure the RCAs are plugged in last. I do it on every radio install, along with running a drain wire from the radio to the amp's chassis. That is how you install any radio right.

Oh so only your way of installing a radio is the right way haha.

None of my installs ever needed any "drain wire". Wtf is that for anyway. In fact I've never seen an install with anything like that.

You sound like the kind of person that uses the wire that is on higher quality RCAs as a remote wire.

It's a little technique me and Canaan do at the shop to prevent any pico-fuse problems in case the customer tries messing with their radio.

I use cheap RCAs they work just as well for most average installs. And always run a remote wire with a 1/2 amp fuse on the HU side.

I'd like to see pics of this extra ground wire just for kicks. Especially how you'd connect one to an amp with a plastic mounting base.

^ didn't i just say something to snow the other day about his post count would be probably double what mine is if he didnt always post useless things?

once in awhile is alright, but this guy over here....



don't get me wrong, i love some of the things he says. but really.














oh and while we're on the subj of head units and some of their many malfunctions, (i've been meaning to ask this for a while) i have an older car, so when i hooked up my pioneer, i couldn't find a memory wire that was in the car's stock wiring. so i just ran a 16AWG wire from the memory on the HU straight to my (+) post on my batt.

thats ok right? i mean it works, but is it bad?

You better have properly fused that wire at the battery or that is a disaster waiting to happen. If you did its ok.

But all cars with a stock digital tuner in the radio have a constant power wire in the radio harness. The only time it may not is on a really old radio with a manual tuning dial.

lol ok then yea you'd have to run a wire. MAKE SURE IT IS FUSED though. Also would have been easier to run it from the fuse box but w/e.
