bought a 1200d from a CA.com forum member in december 2009. hooked it up to verify that it was working in my buddy's car, but it whined pretty badly. all the cables were properly run. about a month ago i built a box and bought a sub and installed them in my truck. the amp has the same whine it did when i bought it and i also noticed has an "power surge", like there's faulty wiring. and yes, the amp is what is whining. i thought it was just the songs we played to test it but apparently not. i relocated then replaced the power cable replaced the ground and relocated the ground with no change. when playing, it's almost like the bass knob was turned down and at random times t…

I have been playing around with my kenwood deck lately and want to make use of its USB direct control thing. I like the idea of getting the numerous CD cases out of my car and being able to control it all off of my deck. the only problem is, whenever I play music off of the USB, it looses sound quality... (volume drops and the bottom end sounds weak). Why would the same song sound great from a CD but sound bad from a USB? Is it suppose to be this way? Also, would the 3.5mm aux imput sound just as bad? I really want to figure out how to get rid of all of the CDs in my car so any advise would be appreciated. By the way, the deck is a kenwood KDC-MP538U Thanks Alex

Hi Im trying to replace my factory battery with an XS Power one. The one and only battery (according to the XS website) I can upgrade to is the D4800. However, I contacted them to verify this and they told me it would be recommended to make some measurements just to verify this. I went ahead and made some approximate measurements (since I did not want to deal with removing all this wires at 11pm) The measurements I got were the following: Height: ~8" Length: ~12" Width: ~71/2 These seem to match the dimensions from the D4800. However, as you can see in the following picture, right next to the bolt there seems to be another hole (RED arrow), it appears to be…

Toyota tundra with stock alt, hid lights, 100rms x 2 channel on the doors and 1300rms on the sub. I'm looking into buying a new battery for under the hood because there is no place to install a second battery in my truck with still a fully functional bed and max seating. I was looking at the kinetic 1800 or 2200. Not sure how big I need to go but I'm pretty sure I can squeeze just about as large of a battery as I could find in the stock location.

Has anyone used or heard about this amp. http://www.sonicelectronix.com/item_23550_Hifonics-Brutus-BRZ2400.1D.html I'm pretty sure I'm buying it but want to see if any of you guys know anything about it. I have the big 3 and a yellow top under the hood and a fairly large stock alt so I should be good volt wise. Any help??

I have a mechman 240a alternator with a xs power d5100 upfront everything wired up and running smooth. Now when installing my rear battery (another d5100) should I run both power and ground wires to the back battery or just the charge wire and ground in the trunk? Thank you in advance.

Hi, i'm in the market for a HO alt for my Hyundai Excel Australian spec, which has proved difficult, to say the least. I was opting for around 220-250A, running to a stock calcium battery, which doesn't do too bad actually, and 2 Stinger SPV70's, which'll be used to push a saz-3500D, (unsure of the sub/s atm) and a sax 100.4 (hopefully), for a daily driver, @ 1 ohm (the 3500D ), with the possibility of taking it to some comps. I'm pretty sure my stock 70 amp alternator wont keep pace with those loads. My wanderings through this sub-forum led me to two brands in particular, after investigating most of them. These two were DC Power and Mechman. At this point you may be aski…

I was wondering how good his amp would be http://www.sonicelectronix.com/item_13492_...SC+1000.1.html# Ive never really used the MB quart amps, I see it is made by MaxxSonics though

I've never bought all the wires and stuff separately, I've only used those amp install kits. Im trying to figure out how much it will cost to wire up my amp and stuff. Orion 2500D. I'm going to need an alternator, I was thinkin a universal alternator... I can make brackets for it, we have welders and stuff and I can weld. Reason why is I have an engine coming sooner or later for the truck, and its a different engine than what is in it. So I'll just make a new bracket for the other engine. I want to run the secondary alt seperate than the existing charging system, and have it dedicated to 1-2 batteries and the amp will run off those batteries.. Not sure what batteries eit…

Alrighty, so i finally got my front stage installed. But when i first turned everything on each speaker has just about as much, if not more, static than music output. I tried messing with the Xover setting and such, but nothing seemed to change it. Amp: Sundown 100.4 HU: JVC KDs100 Mids: AA carbon fibers Tweets: Seas Prestige 27TFFNC/G (H1396) I've only tinkered with the speakers playing for ~10 minutes, for fear of damaging anything. I'm at a loss of what could make this kind of noise, to every speaker. makes me think it has to do with the amp? All of this stuff is brand new. I did plug in one mid, might have done the other i dont remember, to my factory speaker wire fro…

Has anybody checked this amp out yet http://www.audioque.com/aq/AQ3500D.htm I know the 2200 AQ is good and does rated power, should I expect any less from the AQ 3500 ?? Thanks

I got this from the12volt.com---hope it helps.

Hey Guys, I need help from anyone who has experience or knowledge on the AudioControl DQS Processor. I have the DQS (which is an amazing piece) w/ the DDC. I understand the freq (eq) adjustments just fine. My question is on the octave slopes. This is more in depth than I've ever had to deal with or most anyone I know has to deal with. I just plain dont understand what the 1/3, 1/2, 3/4 & 1 octave width selection adjustment for each freq is for, or the purpose of the boost (level) of whichever octave width you choose. Is there a general rule of thumb or a general selection in these settings? I have a big setup w/ lots of power & I feel like I have this great compon…

Hey, I always wondered if my amp would run at this load so today i loaded it down to see if it would go to proctect mode or get hot. To my surprise it seemed to run it well. What could be some consequences of this that may not be obvious? Clipping? Damaged VC's? Damaged amp or would the fuses blow first? It a one ohm stable D class amp. Thankss

Well I ask this question on another forum and I guess to must be too tough or too stupid to answer. I can not find any info relating to this. I am about to include a AudioControl DQXS into my system. I will be running my front stage (MB Quarts QSD 216) active off a Sundown Audio 100.4 amp. I'm new to running "Active" so here's what I don't completely understand... Gain Settings. I have read and understand the input/output level setting procedures for the DQXS. What about the gain settings on the amp? Quote from the manual.... "Now adjust the output level control until the "2 volt" or "5 volt" light starts to flicker. You will want the output voltage to match up to your…

Looking for inexpensive Kinetik contenders. Sealed lead acid...

i read a topic with a guy saying he's running an amp at .5ohms for spl and @ 1 for daily. He was running a sundown 3000 amp.Im trying to decide between 2 dual 2ohms or 2 dual 1ohm speakers. I have a hifonics colossus that's 1600 X 2 rms at 1ohm or 3200 rms bridged @ 2ohms. Will my amp run @ .5 for a short spl burst or go into protection mode. or should i just gt the dual 2s? would it be better to run it at 1ohm each channel daily or bridged @ 2ohms? Thank you

When I installed my alt. it metered out at 14.9 at idle at 260amps. Driving home today I noticed the battery light came on... As soon as I pulled in the driveway I slapped a DMM to everything! Now on all my points I read 26.5 to 27.3 volts....WTF!!!!! I haven't touched a thing since I installed it. What in the hell would make this alt decide it now want to spit out almost twice the voltage? I'm yanking it out for now and putting in the stock alt...(I know it's good) I've had issues with this thing since day one with the annoying whine it puts out of the housing..... Besides the noise it worked excellent...UNTIL NOW!! Any advise would be nice if anyone has any input.. Than…

ok so i dont know what the settings should be on this amp so i was wanting to know what suggestions you guys had that i should set them on cause i will be installing this in the morning. here is a pic of the side,if you click on it you can make it bigger and get alot better view if the settings. http://www.limelighthosting.com/~dave/MK800.4/IMG_0986.JPG

How do I connect these two together ?????

Have an opportunity to purchase a 250A Ohio Gen alt to temporarily bandage my voltage. Has anyone ever used their alts? I heard they put out straight poop @ idle so that is why I am worried. My car idles at a very low RPM: 2004 Pontiac Grand Prix
