Amplifiers / Head Units / Processors / Electrical

Since a week or two, my Pioneer head unit has some problems. Sometimes the "face" doesn't respond, as if there is no power to it. It can happen with the music playing or with the h u off. If I unplug and the plug in the car fuse for the h u, eveything starts working again. If I press the reset button on the h u it starts working again, but I loose some settings. Do you know (or understand) what is happening ? Can it be a simple fix, or will I need to buy another h u ? Please help !!!

I have an alpine 9887 with 4v preouts. I'm running 4 mono amps for my subs. I have been using a maxxling with 9v line driver. I have heard the maxxlink presents much distortion. I decided not to use it on the rebuild. My question is will I have enough rca voltage to run 4 huge amps in one set of rcas.

does anybody no the max watts of the nightshade 12inch 2-ohm, and what is the rms of the 1-ohm?

I'm looking for an amp that will push (2) DD3512E's to either close to the max, or max them out. Any suggestions that will give me that amount of power at 1ohm? I'm running two D4's jumped down to a 1 ohm load. System is stock right now, I plan on getting the big 3 done...and another battery. I cant upgrade the alt by much, only up to 120 amps

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 many in-line fuse holders do I need? 1/0 from front to a Stinger T splitter (http://www.woofersetc.com/p8033/SPD512--Stinger-1-0-Gauge-Tee-Distribution-Block.htm) and 1/0 going to SAZ-1500, and 4ga going to a Alpine PDX 4.150. I am going to order a Stinger 150 to go between the SAZ amp and the T and a 60amp to go between the Alpine amp and the T Do I also need a 250 amp inline up front under hood or is that overkill? Thanks

Howdy, I've ordered 1 fully loaded BTL12, Dual 1 ohm for daily use. I was eyeballing a Soundstream XXX 4000D to power the thing. In talking to an installer, they have suggested that the amp wouldn't work efficiently with the BTL Sub. They are currently trying to sell me on securing two 2000D's from soundstream and running one sub per voice coil. Looking around, this doesn't seem to be the best course of action eitehr. Any thoughts? This install will be in a 2009 Dodge Challenger RT. I'll be going with an Eclipse Navigation head unit. Stock stereo is the six speaker Boston Acoustics setup with a 270 watt amp for mids and highs.

I'm about at the point where I need some electrical upgrades, my car is an 04 Mustang, electrical is stock no big 3, has a Optima Yellowtop My amps Bass amp has 160 amps worth of Fuses, Treble amp has 60 amps worth of fuses. If i play songs with real long bass notes my treble cuts out, maybe its just my sh!!TY wal- mart sony amp, i have a brand new soundstream amp that I'm going to have put in here shortly. Anyway can I put a 2nd battery on the stock alt. or should i go with a 160 amp alt or a 200 amp alt or what?

I was looking around for an amp to run my single 12 inch Crossfire BMF. I was looking for an amp that would put out around 500 watts at 2 ohms. I found the Kenwood kac-9103d for only $200 and its rated to put out 900 watts at 2ohms and its 1 ohm stable. Its CEA rated so I assume it puts out the power suggested. Has anyone ever ran one, or better yet tested one? Almost 1000 watts for only $200 from a well known car audio company just seems to good to be true. I have never personally ran Kenwood amps before, but at that price I am willing to give it a shot. All opinions are welcome. Peace, Lee

So when trying to calculate your voltage, do you use ur ideal ohm load or the actual ohm load measured with a dmm? also say your amp does 1500 watts @ 1ohm, will it still be putting out that much or close to after impedance rises (say to 1.4ohm)?

im probly going with the audiopipe 3000 what do you guys think? and does anybody know where i can buy a stesom 5k2d

ok so i have a 76 caprice i need to know what i need to do to properly power 1 of the saz-1500's im gettn stock alt 63amps brand new 4ga big 3 but upgrading to 1/0 when i get the amp $50 battery from autozone im looking for a decently priced big battery so what will i need to power this thing right

I drive a small car with a 70amp alt and a regular battery up front and with a kicker zx750 and a old sony 50x4 my lights dimmed. I currently am running like 100x2 for my subs so its not dimming but I am looking at 1200-1500rms for bl 15 most likely. I am wondering if putting a kinetik in the trunk is enough or if my alt won't even be able to keep up.

Realistically, how big of amps can I run (D class) in total wattage on a 136 amp alternator? I checked the specs for a dodge diesel and this is what it said of the output. After looking at the number, I'm thinking I'll only be able to run one sub and to incorporate two of the channels for the sub.

I am new to car audio so please pardon any ignorance found in my questions: I recently added a self Powered sub (memphis) to my aftermarket radio (kenwood) The sub is an enclosed unit I have power at the box. when I plug in both RCA cables I dont get any sound, however I can unplug one of the cables at the box and the sub sounds fine (to my untrained ear). I was just curious as to what might be causing this. Any answers would be appreciated Thanks

Can someone post some pictures of there big three setup and maybe explain to me on how to do it that would be great thank you!

Reviews, thoughts, experiences? I'm thinking of getting two. 4000+ watts strapped @ 2 ohm.

Hey everyone, I was just pulling the OEM radio out of my 03 civic, and I was matching up the wires in accordance to my female harness. Everything matches perfectly, EXCEPT within the male harness, there is an extra wire that is red. Here is what the male harness diagram looks like: Radio 12v: white/red Radio ground: black Radio Ignition: yellow/red Radio Illumination: red/black I'm going to skip labeling the speaker wires, because that's all correct. All of that is correct, and this red wire is located directly under the red/black wire which is the illumination wire for the radio. Could this red wires function possibly be the illumination ground? If that's the case, …

I have an xs d3400 and plan on getting another, my problem lies that my altenator has a run of 1/0 to the vehicle fuse/power distribution then charges the batter only after passing through a 140 amp fuse that bridges the battery connection to the altenator charging wire. I plan on running a SS Da Vinci for a 2 way 6.5 system up front and some 5 inch rear fill, and an old school SS tarantula. I will be using BLT4's, will the 140 amp fuse be enough to charge the batteries without blowing, also thinking about taking advantage of a MS-8 processor. please help thank you, also i will have two runs of 1/0 from batt to batt and batt to amp.

now i have been running mono amps for a while, and some have 1 speaker output and some have 2.... why??? like my T10001BD had 2, but my swiss audio SDX2000D had one... i dont understand ????

I recently bought a motorcycle battery, to power a small kenwood 4ch amp. It is rated for 12v/160ca/12aH What is a decent budget charger? I was looking at the Kinetic Three-stage, but i don't have $109 Could i use a regular car charger on the 2amp charge setting?

Still doing a little research, saw some you tube videos on this amplifier and is wondering does anyone own 1, and if so how good is it?

I own a pioneer DEH-11E, and because I've got a new sub on the way, I want to set everything up right this time. Basically, right now I have most of the settings maxed out and/or close to it. I heard that I should never use the "loud" setting, as it will be detrimental to SQ, so I'm curious, what does the "loud" setting do? Is it like bass boost, where it only boosts one frequency? Also, on my HU I am able to set BASS, TREBLE, MID, and "SLA." What is this "SLA" and what does it do? When I add to it, it seems to do the same thing as the "loud" setting, but that is just what I hear with these ears of mine: what does it actually do? Finally, I'm going to start running m…

Currently my setup is as follows: Acura RSX HU: Alpine IVA-W200 Front: Focal Utopia 6.5" and tweets Rear: Focal Polyglass 6.5" Highs Amp: JL 450/4 Subs: 2 Fi Q12" Sub Amp: RF T20001BD I've never tried hooking up 3 sets of components in a vehicle before as I normally have enough with two sets. I was thinking of putting some kick panels in and using the Focal K2 5.25" components I have sitting in my closet. Is there any way I could hook this up without another amp? If not possible, think I would be ok just removing my rear fill and using that channel on the amp for the K2's? Or would that be like too much just coming from the front and only bass in the back...I don't kn…

So earlyer this summer my kicker 650.4 got a little hot and burnt up. I was a Electrical Engineering student for 2 years so I know a little about the specific components in an amp. I took it apart and saw that it was a piece I haven't worked with before and about 10 of the same one fried. This is a picture from ROE(the amp guts section). I had my friend take close ups that I'll try to post tomorrow but he is having problems with his camera so not sure. Hopefully one of you guys can tell me what these are and if i'd be able to replace them. They are the first 4 black pieces under the metal on top and bottom and maybe 3 on the next sets of 3. Thanks, Austin
