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.

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

Ok i shoulda took pics, but hey.. So i have it hooked up @.5 ohms and well yea this system is alot louder than my PA3000db. but i have a slight problem, i'm guessing its an electrical issue, but... I can only turn the system up so far before a big bass note hits and its like the amp goes into protect and then comes right back on, say 2 secs later. SO is it wiring or electric? I'm going to hook the battery charger up to my car to check but any ideas? IT wangs dont get me wrong, but i just cant turn it up louder than a certain point..

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

hello everyone, I recently change all my system and after the installation i get a lot of engine noise and alternator noise. the install was like follows: Alternator: a 250 amp Ford alternator modified to use a voltage regulator, so it generates from 10.5 to 18 volts. Power wire: upgrade to 0 gauge from alternator to main battery, to second battery, to capacitor, to distribution block. Ground wire: upgrade to 0 gauge from alternator to engine, to chasis, to battery, to second battery, to capacitor, to distribution block. Amplifiers: 1 Memphis st-1600d to subs (2 10"Ascendant Audio) 1 Autotek 500s to mids (4 5.25" Crossfire) 1 Pioneer Gm630…

I've been thinking about buying an Oscilloscope for a while now. What should i be looking for when it comes to buying one? What makes one durastically better than the other? For know it will be used solely for setting gains to insure minimal clipping, but I would like it to be able to do whatever else one would do with an Oscilloscope. Seeing as I'm an Electrical Engineering major I know it will most likely come in handy in my future so I would like to get one that has a wide range of uses. So what should i be looking for when it comes to the specifications of an o-scope? Thanks for your time.

I was wondering if it would be a bad idea to run active x-overs at all 4 corners with one 4 channel amp. Like run both left tweeters off of one channel, both left woofers off one channel, etc

what do i need to get for two 18 inch fi btl subs im kinda new at this

i was looking around at profile's site and looking thru their refurbished amps. are these amps worth buying? not looking at buying one right now, but i had thought about getting a few two chaneel amps, bridging both, and hooking them up to my sub. thought about getting a third and powering my front speakers. that would be like $100 ish for 3 amps....can't beat that. Are there any other manufacturer's website's that sell refurbs?? anyone had any experience with them?

I'm looking for an aftermarket processor for my factory system. I've been looking at the JL Clean sweep, MTX Bass ResQ, RF 360.2, and finally the AudioControl. I need a Processor that can handle possibly active set up, 2-4 Channels for mids and highs and lastly a subwoofer output. I like the Clean sweep and 360.2 so i can get a good feel for automatically Eqing ( I know it's not the best but it's a start ). The car is a 2011 Ford mustang With factory everything and stock system. The speakers I will be using are the Bravox CF 6.5's, the amps will probably either be Stetsom or Sundown audio, my budget is at most 600. Essentially i'm looking for the best bang for the buck, E…

I drew out a little wiring diagram(yes i know it's crappy cause it's offa ms paint) for connecting RCA jacks off the HU for my planned system. In the front, the RE XXX woofer will be run off of a 2 channel amp and the tweets will be run off of two channels of the 4 channel amp. The rear midbass(Adire Koda 6.5) will be run off of the rear channel of the 4 channel amp. Crossover duty will be done by the HU(plan to get an Eclipse) and the 4 channel amp. Does that look right? or do i need something extra?

If you had a choice between the Orion 4004.4 amp and the tsunami db4440 (avionix) which would you choose? Is one going to be cleaner sounding than the other or would any difference be negligible? Say you could get both amps for the exact same cost. Its gonna power CDT classic comps (up to 90wrms??) and rear boston acoustic rally coax (40wrms) The orion>>>> http://www.cbrstereo.com/Merchant2/merchan..._Code=ORIONAMPS The Tsunami>>>> http://www.avionixxusa.com/ep/db4440.htm

Pioneer Premier P880 PRS, easily the highest end deck i've ever bought. 24bit dac's, l/r seperate eq's, 5v outputs, a ton of xvoer points. here are some pics.... http://www.sonicelectronix.com/pictures.php?id=6822

ok, I have to admit, I have an amplifer addiction, at first it was just with classic RF amps, kicker ZR's, Orion HCCA's, with a fwe ZED Audio produced US Acoustics... but then I started branching out my interest, and I sorta follow how are the amplifer people online and I pay attention to their choices and learn from their mistakes or good choices, guys like Josh Laine, zane (below reality), SQStephen, PerryB, and Tirefyr (aka ryan) are just a few that come to mind, so to get on with it, I have been an MB Quart follower, not always been able to afford their products, in many cases opting for lesser expensive pieces, so when Ryan orders the MB Quart right after he orde…

Im in need of some help... I have a problem that just started recently... at random occasions... my deck will flash off then back on... ushually several times in a row.... but if i turn down the bass... it will stop doing it... then i can change songs.. turn the bass back up... and it will play fine... switch back to the other song and it plays fine.... this cutting out crap is getting really annoying... and its like it only does it right before it should hit hard... ushually after the car has been sitting for a few hours... on the first hard hitting song i put on... the first time its supposed to hit hard.. the deck wi…

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…

My Pioneer MVH-8200 recently has been having faceplate issues where it seems like it isn't making a good connection and if I push in the faceplate sometimes it causes the unit to turn off then back on (most likely because it loses connection then regains). I live in maine so it gets pretty cold and I'm wondering if there is some moisture in there that's causing issues. If that is the case what do you think I could do to help clean off the connectors? I tried looking on ebay and amazon for a replacement faceplate and couldn't find one, and when I emailed pioneer they gave me the usual round around with warranty (which I don't have the info for since I bought it used)

I just ordered two 12" aa havoc's which are 1250 rms. What would be a good amp to run on these. I was looking at sundowns but didnt know if i shoudl wait for there new 2500 watt amp to come out or what

Basically I cannot get any pre-out voltage from the HU for the sub-out. With volume all the way up on a 50hz tone pre-out voltage is ~.69 (tested directly at the HU). Put the leads on the mid output... .69 as well. Put on a 1khz test tone.. DMM on mid outputs... 3.69... on sub with 1khz.. 3.69. So basically I'm pretty sure nothing is wrong with the actual pre-outs but I am missing an option or control on the HU completly. I have the Subwoofer set to +15 and it's set on Subwoofer system 1. The Crossover and PEQ don't have the level turned down on the sub... so I am

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

I bought a SAE-1200Dv2 and i have it hooked up... i am running two alpine type r 12s duel 4 ohm voice coils at one 1 ohm and the amp keeps shutting dow... it will play for a while and it shuts down and gos into protect.... i turn the volume down on my HU and turn it back up and t works... what could be causeing this...? any one know?

well i toke my deck out the other day and when i put it back in iv got this nasty buzz like real nasty and it will change with engine rpm and there is also a bit of "engine wine" but the buzz is much louder and the really weired thing is if i change source or change channel or if i turn the volume from 0 to1 or from 1 to 0 i get a nasty thump kinda like a turn on thump but louder. I checked my amps grounds and they seam to be fine i was thinking maybe its my deck's grounds or maybe i broke a ground strap somewhere in the car im going to try changing them tomorrow my day off. And i also tried a different deck and it does the same thing but they are both pioneers and i hear…

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…

Does anyone on here know how to install one. I need direction. Sincerely, Matthew
