Is there a way that i can test voltage drop with a digital multimeter

Hey guys,I'm purchasing a few things for my 2003 GTI and I was wondering how much of a difference (quality wise) a head unit would be. I was suggested Alpine CDA 9887, but was wondering if it would really improve the sound, or should I just stick with something cheaper, since I am in school and kind of strapped for cash to get a head unit with all that stuff. What I plan to purchase: Helix HXS 136 Esprit Sundown SAX-125.2 Fi Q12 Diamond audio D3 800.1 or Sundown SAZ1500D(used) Cheers!

just like my title says, does anyone know where i can get the remote gain for my aq3500? should i contact aq or what?? Thanks!

I recently took out my big heavy soundsystem due to the weight in the back causing traction issues up front.( gonna fix that this summer i hope), but for now i took my two kinetic 1800 batteries out. I went out and bought a cheap battery maintainer thing from advanced autoparts, it says 1.5 amp maintain. My question is can i paralled the batteries together and hook both up to this one maintainer or would i need to get another. To me it seems fine, it would still be seeing 12v to maintain. Right?

I'm trying to figure out what electrical setup I need to support a 3000+ watt system. I'm thinking a DC power 270A H.O. Alternator, XS Power XP3000 battery as a secondary, as well as 1/0 through out , of course I could be off with this assumption.

So i am in a debate between the Fi BL 15 and Fi BTL 15, the deciding factor is wether or not i will have the electrical support for the amplifier. I am wondering if i would have enough electrical to keep up with the Hifonics BXi2610d to run on the BTL... Here are my specs... Electrical: Stock Alternator 105 Amps Stock Battery Up Front Big Three in 1/0 One run of 1/0 to Trunk Power Acoustik 5.0 Farad Cap. ( start criticizing, it will be gone in the new setup) I have been running 1100rms at 2-ohms with little noticable dimming while sitting still, but none while driving. I plan to add a Kinetik 1200 in the rear with the new installation. My voltage has never dipped below 1…

Picking up one from a friend as part of a great package deal in a few days and i am trying to get a little feedback from anyone who is familiar with them. It should suffice for now until i have time and $$$ to build something better. I'm picking up the amp, a Rockford T210d2 sub, a sealed box thats basically useless but still, and a 0 awg wire kit for 350 dollars. Basically i just wanna know if the amp or the sub are the weaker link and which i should replace first. and also if you guys think that it will run an icon 12 ok until i get my sundown? and then hopefully an Xcon insides look fairly beefy

Does the SPL FX1-4000D amp do rated power? Or does anyone have experience with it?

So I was just about to buy the AudioControl lc2i and I saw that it has "2 speaker-level inputs with 400 watts RMS power handling". I have 2 crescendo bc2000s and going to have 1 crescendo c1100.4. I won't be using them all at full output, but somewhere around 3.2k rms all together. Does that mean it can be hooked up to speakers that are getting up to 400 rms or does it mean that it can only support amps up to 400 rms. I looked at reviews to see if others have used with more power and they were all under 600 rms. I didn't see any other LOCs that support more power. Will the lc2i work? If it is that I can't use this one, are there any other LOCs I can? Thanks. http://www.cr…

I recently bought a kinetik hc2000 from amazon.com, price wasnt too bad at all.. now im looking and there out of stock for a while, dont know when they will have more. shipping is estimated at 1-2 months,.. i cant wait that long lol.. Is there anywhere else you guys know of to purchase these battery's at a good price?

can i run my speaker wire and rca cables in the same door jam or do i need to run them seperate. power wire is seperate from rcas but does speaker wire matter or not another questions trying to wire up my apline 6.5 coaxils how do i know which one is the postive and which one is negative or does it matter

I've been keeping an eye out for amps lately with the intent to buy a sax-100.4 but looking at crutchfield they have a p450.4 which is rated at 60x4 for a pretty good price. I looked at ampguts and it seemed to look pretty sparce inside, but I'm no engineer so what do i know? I would run this amp with the front 2 running generic 6.5 speakers on the front and the rear 2 bridged to an id10v3 D2. What do y'all think? Thanks John

Ok i have a audiopipe ap3002 and the it stoped working and now the power light is flashing. is it toast or can i fix it??????

I am looking into adding a second battery and all i need to know is whether i am missing any big deals/sales right now, or if anyone has a better option for me in the $180.00 range?! Can anyone point me into the direction of a better "deal" than the hc1400 for $165.00?! eBay Thanks!

Do not purchase these amps from the ebay seller riversidetrade they are defective. They were never supposed to be released to the public. The heat sink is to small causing them to overheat and fail. On the good ones the heat sink extends out beyond the case. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...;Category=39739

What do you guys think of pioneers new avic line coming out the F series. I think I am just gonna wait and get the F90BT I think it is, it looks freaking awesome compared to the D3.

id like to know: how vital is a crossover? and does it really make that much of a difference in sound quality? if so, is it really worth buying a good alpine one for $350...alpine vxa h701 http://cgi.ebay.com/NEW-ALPINE-PXA-H701-EQ...1QQcmdZViewItem thanks

I'm looking for adapters that are 1/0 and have a pin on the end to make it easier to plug the wire into the amps, dis. blocks, etc. I cant find theese things anywhere, can someone help me find some? Thanks

i just ordered 2 kicker L7 12s and idk wat amp wat size amp or wire to use any help would be appretiated

I just installed a hifonics Zeus zrx3000.1d. I was wondering if a 4 gauge big 3 upgrade would help with the light dimming and give the amp more consistent power? Any ideas? If so, I saw on knukon

Ok so I have a crossfire VR4KD, and this amp has 2 4awg positive inputs & 2 4awg ground inputs. My question is this.... Is it neccessary to have all 4awg as inputs (+ & -) or would it be a problem to run 2 pos 1/0 with 4awg reducers and 2 4awg as gounds? Will the grounds being 4 and the pos being 1/0 be a problem for the amp?

i have a 1999 mazda b2500 pickup. i am about to install a big three upgrade and was inquiring on a ballpark figure of how much wire to buy. I was thinking around 8 feet or so but how much wire did you guys use?? Thanks, Matt Cusack

Its time for me to install all my gear, ive installed few HU's here and there but never a full system consisting of multiple amps, subs, rear battery, and components. I was told to run a line of 1/0 from the front to the rear + batt terminal, and ground to the chassis of my car. Fuse few inches from front + batt. terminal. For the rear battery, do I fuse inches before the rear battery? How big of ANL fuses should I use, I will have 170 amp fuses in total from my amps, so maybe 200 ANL fuses will be good? Then from the rear battery, ill be running some 1/0 gauge to a dsitro block and will give me 2, 4 gauge outputs that I will connect to my amps, (AQ 1200d, and Kenwood KA…

Generally, What frequency range do my mids play if my EQ is flat? Thanks in advance.

I was going to write a giant post, but figured this will be better Vehicle - 2006 Ford F-150 XL What I plan on doing: Fi BTL 18" power by Lanzar Opti6000D 8 Pioneer 4-way 280W Max 6x8s on 50Ws each Supporting upgrades: HO Alternator, something with a high idle output Isolator splitting between stock battery for car and 3 batteries in bed of truck Big 3 with 0 Gauge 0 gauge from alt to all batteries Fuses throughout system Voltage meter in dash If you assume I know how to correctly make a ported box, and how to wire stuff, is there anything I am missing or should do in order to make the system more stable? I plan on using 0 gauge for grounds, but feel like I should ask her…
