How do most HUs hold up under high voltage, say 16V?

I've heard a lot of people complain about the same problem, but what do I do to solve it? If, I need to reground something, which wire/s go where? I'm not too knowledgeable about this nor did I install this on my own. My truck is an 06 Silverado

I bought an 230A alternator from Nations Starter and Alternator in Cape Girardeau, MO about a year ago for $450, my warrenty is expired and now its squeaking. I spoke to the guy at the store and he says that there is no way that alternator is squeaking he said that he was 1000% (yes 1000%) sure it had to be something else but not the alternator. He is stuck on his work being perfect. All I can say is that I would never ever buy anything from them again. Ok now that thats out of the way, should i take it to an alternator shop to get it fixed, or should i just get a new one. And if so where can i get a 200-250 Amp alternator for a reasonable price? Its for a 2000 Dodge Dako…

After my friend pulled his equipment out to get to his spare tire, he replaced it, but could not get the fuses to stop blowing. The way the story has been told to me, he has hooked everything back up the way it is supposed to be, started it, blew the fuses, bought new fuses, blew those, too. What am I missing here? Or what isn't he telling me? Anyone have a solution?

I have been considering running dual alts in my silverado and was wanting to know a few things... 1. I have a Mechman 270 installed right now. Can I install my stock alt and add the mechman back on a dual alt bracket? 2. Can I use the stock alt to run stock electrical and the mechman to run everything else? Or do I have to run them together? 3. How do I wire in the second alt if its possible to run the different sizes?

what is a good number, and what does this mean?

Ok guys I'm looking for some advice towards the two topics as stated in the title. I'm running a sundown Sae-1200d and an FI bl 18". Currently stock alt , stock batt, all 1/0 ga wire and batt neg to chassis ground in 1/0. I'm initially looking to put a new battery up front or (possibly in the back) but the new batt would be running of the stock alt for while whether it be in the trunk with the stock batt up front or the new batt up front solo. I'm looking to save some $ up and get a new ho alternator in later on. Right now I'm looking at the kinetik hc1800 which does 1150 cca and fits my budget of being under $250. This battery will also fit up front under my hood as wel…

what is the pre amp voltage in deck do? what would be the difference between getting a 4 volt pre amp deck and a 5 volt pre amp?

I know to add up all my amps fuses and the total is my in-line fuse size. My question is about fusing at the db block. I've read in a previous thread on here to fuse under never over( i.e. 180A = 150A). I have an amp (US Amps USA-150) that requires fusing at 75A. It has 2 inputs for positive and 2 inputs for the ground wires. Can I use a 40A + 30A = 70A fuse in my db block or will it affect anything being different sizes and under the fuse rating? Thanks and have a Happy New Year!

waht setting do you put your dmm on to check wattage??

I have an alpine 9886 and pxa-h100 crossover. I've looked through the menus and don't see a bandpass option for an active mid range woofer. I looked around the Internet and didn't see anyone running active with this setup. Did I just not find what I was looking for? Or is it not capable? If it's not then pioneer p880prs here I come. Right now I'm using the passive crossovers with my focal 165a1's woofers in the stock location low in the doors and the tweeters mounted low on the pillars. And powering them with an alpine mrp-f250.

How do you hook up the navigational system in a 2006 Lincoln navigator to an aftermarket radio.......or do I have to buy an adapter...""......'also can u use the factory DVD player with the aftermarket radio..

I know that the 3500d is on presale, how does the presale work? Were can I order them and how long does it take before I would receive them.

So I need some more power, I did my research and decided to go with Mechman, Called him up and can start by saying his customer service was top notch, hes very friendly and easy to talk to, answered every question I had for him. Heres some photos of the install. It was very straight forward and easy to install, I give the service and product a A+ and would reccomend it to anyone. Yes I know its dirty under the hood but I had no time to clean it so on with the photos =] Stock Alt removed the plastic engine cover Pulled the OEM Alt moved a couple things and the re-install starts another shot all back together and the test Once again I couldent be happier with the eas…

when you tune ur amp, do you have the bass level on the headunit at 0, or at the lowest it could be, i have it at -6, but was going to re-tune using it at 0 what u guys think thanks -Irvin

Maybe I can get some help here. I'm looking for amplifier choices, I'll be getting 4 RL-P 15's, probably being put into a smallish ported box. I kinda want to keep amplifier cost below 800$ if possible. I'm at a bit of a loss, on what to get. There are too many choices! I've considered getting a Hifonic Titan series TX1000 per sub. But maybe two stronger amps would be better. My truck has two yellow tops, and a mean green alternator. So any recomendations would be nice.

So what would happen if I crossed the power and ground on the amp? Yes, I did this accidentally, for less than 5 minutes ! The amp does have a reverse polarity protect on it, but what damage, if any, have I done? Is it completely fried? I went ahead and put the wires back in correctly, and I still got no sound to my fronts. Thanks for your replies

i finally made a decision on a sub to go with. im going with a SSA Icon in a ported box, 4cu@33hz and would like some help tuning the amp so i dont tear up another speaker right away. I'm goin to set the gain according to the tutorial on the jl website but need help with the other settings. i already know to leave the bass boost off lol. i mainly need help with the infrasonic filter(infrasonic freq.,"Q",Center freq.) i assume the LP freq should be set at about 80hz correct me if im wrong tho. should the slope be on 12db or 24db, im guessing 24 but could be wrong there too lol. also as far as the lp and hp filters on the head unit do they even have any effect on the amp? t…

http://cgi.ebay.com/KICKER-PKD4-4-GAUGE-DU...1QQcmdZViewItem will this amp kit work for a kicker zx1000.1 and a zx350.2?

ok so last night and all day today everythings been great. setup has been beatin pretty good. ok so i went to my ol' lady's house today and had no problems what so ever on the way. my car set for 4-5 hours. i go to leave and my car wouldnt start. thought it might be a loose batt terminal checked that didnt work. my voltage meter said 12.8 turn the key and it would go to 0.0 then to 9.0 and back to 12.8. ended up using a jump box to get it started and voltage went right up to like 15.3 with the headlights on. if i turned my volume up over 1/4 up the stereo would shut off ,lights would dim ,and voltage would drop to like 9.0 ...hit the highway and i could turn it bout 1/2 w…

Hi guys, I'm transfering most of my gear from my old car to my new one. I had a 03 tdi with an Alpine HU ida-x305s with imprint module and now got an 12 tdi. I like the oem radio for all its features: hands free, sirius/xm, the iphone/ipod connection. I got myself an Audison Bit Ten D to tune in all my gear and got into an argument with a friend of mine about keeping the oem head unit. He says that the oem head unit is garbage and it doesnt matter how good a sound precessor is, if I feed it garbage in with the oem HU, it will give me garbage out to my speakers. I would like to have your opinions on this subject. Thanks.
