Amplifiers / Head Units / Processors / Electrical

I just got an L.A. Sound 4 Channel amplifier, model number S835, it was given to me by my uncle, I tested it with a 6x9 and a PC power supply and all the channels seem to work, it's supposedly 800 watts (max I'm assuming), has anyone ever heard of L.A. Sound or used any of their amplifiers? Were they any good?

I was just wondering if this is possible, or even worth it? I have never seen any manufacture attempt this, but I believe that it would improve the quality of the sound as well as be cost effective in the aspect of less material/weight/mass that three sets of RCAs use. I'm not sure if anybody will be able to answer this question, but I was just wondering what is the reason for manufactures pursuing this route. Any opinions are welcomed.

i recently got an internship and in our engineering lab where i work we have many oscopes. i was wondering how i would be able to use the oscope to set the gains on my amplifier

i need fairly reasonable amp(s) to power these two drivers, also how many yellow tops would be good for this application if im using a 200 amp alt? if its not two much trouble can someone break the channel thing down for me as far as when you would use what type of amp..

Hi, All, I have a couple questions related to the internal subwoofer crossover(?) of the Alpine CDA-105. So far, Alpine Tech support and Crutchfield "advisors" have been unable to help -- they only know what's in the manual, which I am perfectly capable of reading myself! 1) Does the High Pass Filter function (60/80/100 Hz or off) affect only the front and rear line or speaker outputs, and NOT the subwoofer output? I would assume only the front and rear line or speaker outputs would be filtered, but, the manual does not clearly specify. (See page 14 of the manual.) http://support.alpine-usa.com/products/documents/OM%20CDA-105_EN.pdf 2) Assuming my abov…

Hey guys. I'm just looking at buying the Pioneer Premier DEH-P880PRS and was wondering what people's opinions were on it. Looks like a solid unit for a good price, but I just wanted some feedback/info about it before I bought it. Thanks, Mason

Hello all. Its just a distant thought (depending how achievable) what does it seriously take to run up to 16 volts on electrical? Ive never asked. And i have no clue. I hold steady at 13.7-13.9 after the batteries top off. Is it as simple as 16v batteries and a 16v charger (ho alt also of course)

has anyone used these? nothing pulls up in the search.

I am getting a lot of different noises coming out of my speakers. I have had this problem for a while. I thought it was my pioneer head unit but I guess that proved to be false. I have installed all new grounds and everything is wired correctly. I am getting not only alternator whine but ... noise from when I turn my fans on (ac/heat etc) and the noise increases as I increase the fan speed noise when I turn my signal light on or yield lights on - they noise pulses to the clicks of the signal lights noise when I turn my interior lights on and as the lights dim the noise dissipates. The wierd part is, if I turn my car onto accessory the noises are no longer there. These no…

ok so i originally planned on 2 hifinics 2608s but was advised against it.....so any recommendations. and price is a huge factor so the cheaper is nicer

I have this amp and it says 600 watts @ 4 ohms.I know it has more power than this I just dont know how much. If anyone knows the specs on this amp it would be helpful. What ohms is it stable to? What should I fuse this amp at since it has no fuse on it? Does it have an unregulated power supply? Class ? It is an oldschool amp but I would like to run it, just need some info. It was made by ZED audio . I have searched the internet but found limited info. Any help would be appreciated.

will i saw a car with a pc in it over the weekend and i want to do it but don't know it it is going to work better the a head unit so if have done this or if you know if i can do a sq build with it

First off, i got this radio from my brother for finishing his basement so i have no actual booklet. i have downloaded the 177 page owners manual from Pioneer. i just installed the radio today in my 2004 Blazer and love it so far but... i am running component speakers and a subwoofer. i hooked it up like the manual told me to but i can't turn the sub off or fade it out. i turn it to the sub setting and try to turn it off and nothing happens, i still get bass. also, does anyone know where to get the microphone so i can time align the system? i'm going to be running the tweeters and mids active soon but i don't want to try and deal with that if i don't have the right tools…

I was happily enjoying my new (old) amp, when it turned off. I assumed the remote wire came loose again, end of story. The terminals are screws but with no plate so it slides out easily. (Before you ask, no short, it was in line of sight the whole time). I re-connected the remote wire, and nothing. Simply will not turn back on. No blown fuse, no smell, heck, not even warm. I have no idea where to begin looking for the culprit. I'd post pictures of the damage but there is none that is visible... Any ideas on how to fix this situation? I love this amp, and would hate to retire it to paperweight status.

I am buying a yellow top from my friend. It is taller than my original battery and the wires won't reach.

What do you guys prefer... Rockford or sundown

I have a 2008 yukon with the stock alt and a optima yellow top and the big 3...my electrical has always been enough for my setup,im only running around 1300w but a week ago i left my light on and the next day my battery was drained...i jump started it...but now my voltage at driving and iddle drops down to 13v...before it ran around 13.9-14.7v...i used my multimeter and 13v is whats the alt is putting out...my battery with the truck off is 12.6v.:.here is the funny part...if i turn on all the lights and the front and rear AC the voltage jumps up to 14.9...is my alt dying on me or is it the batt?

Quick Question, I'm looking for a new front stage amp since the 3522 isn't really cutting it anymore. I'm searching ebay for used 2 channel amps and I came onto this "Cadence Ultra Drive Z1200" as well as many others. Before i start considering the Cadence I tried to look it up for RMS wattage and other specifications. Upon research, I've found different information from different reliable resources. However, i found nothing specifically on "Cadence Ultra Drive Z1200". I found stuff on a Cadence Z1200 being a mono bock, and stuff on a Cadence Z1200c being a 2 channel. I don't suppose anyone out there has any useful information for me on the Cadence Ultra Drive Z1200? Th…

So I picked up a pair of Hertz Hsk165's and need some help with choosing an amp. Amp will be ran off of a kenwood 8120. I have about 400 to spend... but I wouldn't mind spending less. Im thinking about the following: sundown sax-125.2 $240 (even a 50.4 bridged thoughts???) audio systems twister 300 $300 jl 300/2 $350 steg K2|02 $450 arc ks300.2 $399 what are your thoughts on the ones posted? any recommendations?

I own a 2003 sunfire which currently has a 105amp alternator. I was looking to run about 1300rms off it, but I know the alternator isn't big enough. The problem I'm having is that I can't find anyone who builds a high output alternator for my car, and I looked into getting it rebuilt, but I can't do that either. I don't know what to do. Are there any specialists for problems like this, or am I screwed?

Sorry for asking such a basic question but I used the search feature and I can't find anything on it. I am planning a build for a BL 15 in about 4 cubes and I need to know how many RMS I can safely put out on a sundown amp with a 130amp alternator without dipping below 12v too severely.

My Christmas gift from my family is going to be a new HU. I'm replacing a Dual unit with either a Pioneer or Kenwood as I've heard more good things from those 2. The new Pioneers have android app control through Bluetooth. The BT in my Dual has pretty crappy volume compared to plugging it through the aux jack. Are all units like that? Or is it just the fact I've been running a lower quality HU?

Ok so I installed my Stinger voltmeter last week and tuned it or whatever with my multimeter and it works perfect,.. but now that I can watch my voltage.. it is weird. Sometimes when I am driving it goes below 12v.. this is even if my head-unit is off, no windsheild wipers, no headlights no ac.. nothing on just driving and it randomly went to like 11.6 even.. I have figured out my "normal" voltage when driving is usually 12.5-12.7v... like that's what it stays at most of the time.. but when im driving I notice it is randomly at like 11.9 then later its like 11.6 and its for like 5-10 mins sometimes and then sometimes it goes back to like 12.2 or 12.5 and just fluctuates a…
