Will I see a big difference if i update from an aq3500d (old one 3500 watts) to a saz-4500? I am looking to get my 2 dd3512e louder. Would this get me there?

Well, my friend has recently been having issues with his electrical system. He currently has a red top and yellow top in the back. He reads around 14 volts up front but his battery in the rear (not isolated) reads at 12.5 volts?! The battery in the front and rear both read at 12.5 with car off. Any clue what could be causing this issue?

Hey I have a crappy voltmeter from an autoparts store locally that my friend hooked up a year ago to who knows where in the front of the car, I think to a fuse for power just so i have an idea of my voltage.. But I am about to purchase a new stinger voltmeter as I am about to add a new Kinetik hc1400 up front and decided I want a more accurate reading of voltage for my Sundown amp. I was just wondering how you guys wire these up to get a good readout of the voltage? (I guess at the amp?.. ) I'm assuming you would want the voltage at the amp to see how much power the amp is actually getting?.. correct me if im wrong about what voltage i want to read.. so basically I was j…

Alright, I can get this amp for 350$ maybe a little cheaper. Would this be good for an 18" btl? I don't want to push 4400 rms, becuase my box is 7cb ft, so I figure I could just put the gain down a great amount. I know these are power hungry, but aren't tehy like 450 amp draw? I would have 2 C&D tech batteries (88 amp/hr with a rating of 340 watts/cell), 2 ought wiring, 200 amp alt, and soon down the line upgraded under the hood batt. Would that be sufficient? Would these be a good match if I set the gain according to like 2500 watts?

I'm currently installing a rather large system in my car, and using an alpine ida-x001 as the main unit. Only problem is the unit does not have a CD player, and I really don't wanna deal with a seperate CD changer to hook up to it. i have another alpine deck with tilt, the CDA- 9851. Not sure if i would need some sort of switch-board for all the RCA-s or not. I would like to be able to use either deck and still have full usability of every part of the system. So having both decks would def. be ideal.

So this is what I am thinking. For my 2 zcon's I need more. They want more. Currently have a 2500d but was thinking of going with a 4500d. Or maybe even 2 2500d's strapped. Only problem is, zcon's are 1 ohm. Every where I look, for strapping u want 2 ohm. Which way should I go?

I just installed a DC Power Engineering's 250 Amp Altenator XP on my 2010 Camaro 6.2l and the belt squeals on cold startups. My car has 6600 miles on it. I have a new belt on order and will try as soon as it comes in. The alt came with a smaller pulley on it Im wondering if I may need a shorter belt, maybe the tensioner is not tight enough with smaller pulley the Alt came with. Any suggestions? What about changing out the pulley with the stock one? Though Im sure the DC Power Alt came with a smaller pully for a reason?? Scott

My first official post of audio haha . Just had a quick little question, I have a 18" Fi BL and i want a good amp for it. So i am deciding to get a 1200 AudioQue amp or a Rockford Fosgate 1500-1bd. Any idea which amp I should get. Thanks guys !

Hey guys, Sorry about the long wait but I have been VERY busy---I got out of the military,got my BSEE,moved to Virginia, and am buying a house as we speak---it is ALOT of work.If you need anything just send me a personal message---I will try to get on here more often! Peace and HAPPY NEW YEAR! Dave

Is MA Audio any good? I think they are but haven't heard any myself. Thanks a lot.

right now my battery is grounded to the front of the drivers side head (which is aluminum) i get a bit of noise every now and again through the front speakers and probably inaudibly through the woofers. the passenger side head is grounded to the chassis, above the motor. its all 4 gauge. i'll get a better ground by grounding the battery directly to the chassis right? then i just leave the head grounded above the engine the way it is? i know it needs to be bare metal, but can i just ground it anywhere thats metal on the body of my car, or does it need to be directly to the frame?

I checked my battery, nothing is touching + and - I checked the amp, the power wire and ground fit nice and snug with no loose strands The amp worked last night......all i did was unhook wires, move it to the trunk and hook the wires back up....I'm at a loss The only thing i can think of is its somehow shorted in the amp, but i didn't shake, tip, etc. since last night...i don't think the power wire is cut since i turned the car on and the fuse in the engine bay is fine. I have an AQ1200D and two SDC2.5 subs by the way.

I currently have a 12" fi ssd (800 rms) with an alpine pdx 1.600 (600-700 rms), and I'm thinking of upgrading to 2 fi ssd 12"s with the new saz-1200d. I'm willing to upgrade from 4 to 1/0 wire, and I already have a yellow top, but will the stock alt in an 03 passat be able to keep up without terrible voltage drop?

I currently have a P550MP (see sig) its a premier line, wma/mp3 capable, i believe 2.2V outputs (3 total) etc. etc. and was wondering if it would be worth it in SQ and features and just overall to spend the money to upgrade HU's? i would be buying the 860 used so i would be paying 200 ish...thanx for all the help...

My audiobahn 18001DT amp isnt getting enough power out of my car a 2000 Mazda Millenia S. The stock alternator is putting out 110 amps the amp is drawing 150 amps to put out 1800 watts to 2 12" audiobahn ultra excursion subs. I have upgraded the battery to a optima red top and have installed 2 1 farad caps. When i have the car running the amp recieves 13.5-14 volts when i have the bass turned all the way down. When i turn the bass up half way the voltage drops within 5 minutes to 11.5. I currently have 4 ga wire planning on upgrading to 0 ga to stop some of the voltage loss cause im running the wire 20 feet. should i upgrade the alternator or put more caps or a battery? a…

Hi my step brother has two phoenix gold octane 10s and a phoenix gold 2 channel amp, and when he has both subs hooked up the amp goes into protect mode but when only one is wired to it it plays fine but when u hook two up again it goes back into protect mode... occasionally it will play with both wired up but only for about 1 min. then it goes back into protect mode until 1 is unwired. is it the subs or amp (oh yea one of the subs sounds like its blown but still plays just distorted)

I am trying to pick a headunit out. I thought I had it figured out and then decided I was definatley going active. My problem is that I need a HU that will allow me to go active but still play MP3 discs as well as have somewhat decent ipod control. So ive got four picked out price really isnt the factor although $450 is my budget and I am not against buying used. Alpine CDA-9835 (hard to find and are somewhat expensive when found) Alpine CDA-9855 (I can deal with glide touch if need be. its not THAT bad) Pioneer 880-PRS (Easy to find and moderatly priced, some complaints of "snakes in the unit") Eclipse CD7000 (Easy to find but on the higher end of my budget) There are a …

what is everyones opinion on the kenwood kdc-x790?

Just wondering if anybody knows anything about the Rockford Fosgate RF-BLD. it says install it as close to the source unit as possible, why is that? Why can't it go in the trunk by the amp?

Going to be running an alpine pdx-f6 (60amp fuses), and alpine pcx-m6 (80amp fuses). Would 0ga just be over kill? These are going in the rear of a crew cab colorado and splitting at a distribution block. So it will be ether 0ga in and 2 4ga out or 4ga in and 2 4ga out. Thanks

ok well i have a build come up on monday and i was wondering where to run the 1/0 i mena i have only ran 4awg and that was in the kick panel so i dont know where to run that big ass wire

is there a kit for this, or do i just get some 0 or 2 gauge wire off a spool, Sorry, but i know nothing about this

so i am wanting to buy a new amp for my Focal KRX2's ...they are 2 ohm... i will post specs below for the speakers... right now i have them ran off a candence TRX 3004 bridged.. they seem to like power.. i bought the Boss audio zed built amp and was going to try it.. but after getting it and seeing how they want the power wire to hook thru the little spade connectrion it kind of turned me off .. going to be hard to find a way to hook my real 4 gauge power wire to it... so anyway.. now i am going to buy another amp... i want something that sounds good.. i was thinking of the Zed audio Kronos.. wanting to spend around $400.00 .. so would this be a good choice ?…

I'm in the process of doing the big 3 in my '99 Grand Am; problem is, I only have 2 ring terminals to work with right now. Question: If I do the run from my alt to the battery with 1/0 and leave the grounds with the OEM cables until the rest of my terminals come in, will that cause any issues? The current flow to my battery will be improved, but the grounds from the battery to chassis, and engine to chassis will be the same as before. Will this be ok, or should I just wait til I get all my terminals in to do the entire upgrade at once? Thanks in advance

could someone give me a list of amps that do 2500 watts at 2ohms.
