I have just finished receiving my impedance curve measurements for my setup design between 20hz-80hz. Here shortly, the graph will be posted here and in a few hrs, me and a buddy are gonna take a trip to an isolated area where we will be measuring output and efficiency and comparing those numbers with the SAZ1500D as i've always wanted to know if the AQ outperforms the Sundown since it's rated to do more power but only at a higher voltage. As of right now, - Impedance curve ranges from 1.76 ohms to 21.6 ohms. DCR is 0.7 ohms So... i will NOT have any measurements below 1.76 ohms and depending on heat buildup, i'm still hoping to pull some numbers out of the AQ below 2.0 o…

will i need to run a relay between my starting battery and a kinetik 600 in the trunk? if so, what size would be needed?

im upgrading my sub to an xcon probably 12..maybe 15 (id like to get atleast some hair movement for an extra $10 why not) gunna be running it of a rockford fostgate 1500w amp: http://www.sonicelectronix.com/item_26139_Rockford-Fosgate-T1500-1bdCP-2010-Model.html a few people said that their birth sheet said 1900W battery to amp is 4G wire im driving a 98 honda crv so its a small suv question is... for running that amount of power do i: need to do the big 3? need to upgrade the stock battery (51R there pritty small) OR add another one? What would be the ideal set up to make sure everything is working full potential? and do i NEED to do it? Reason im asking is im probably…

Currently I'm only running 2 amps and just run the remote wire from my HU to both amps, but I'm going active and will be adding a Kicker Front Row and possibly an Audio Control EQL. I don't think the single remote turn on from the HU will power all 4 components and I'm looking into relays. I hit BCAE1 and I think I need a 12V 40amp relay, but the wiring diagram shows a distribution block for the remote wires in 16 gauge. Where would I find one? What do you guys do? I looked at autoparts stores (I will not pay $6 shipping for a $5 part) and found relays but I'm clueless as to where to find distribution blocks that small.

just got my amp. in the box it came with a paper that says "Total Maximum Power Output: 930 watts." can anyone explain what exactly this means? like is it at 2 ohms at a certain voltage or is it the 2 ohm and 4 ohm ratings total added? or what? thanks!

Just upgraded my headunit now have the Pioneer DEH-P610BT it looks great, and I've always loved pioneer headunit. Anyone have this headunit? Opinions on the microphone and bluetooth? http://www.pioneerelectronics.com/PUSA/Car/CD-Receivers/DEH-P610BT Can someone tell me which frequency I should have for my subs on the radio??? I was always told 80hz is good.

What's a good low pass cross over for my MIDs so they don't play to high. Crescendo mp6's are what I will be using. And a mbquart onx 4.125

Been off pursuing other hobbies and raising a little girl... My DNX8120 is dying a rapidly accelerating death. First the XM receiver takes an intermittant dump over the last year. Then the disc transport died last month. Then some low life stole my in-car iPod. Long and the short I need to replace the HU because I'm basically down to listening to the local radio station. In a small town in the middle of nowhere, that is absolute torture. Requirements: Double DIN Nav DVD XM capable (NOT Sirius so the new Kenwoods are out) Parking brake lockout is easily bypassed Good Bluetooth (the 8120 has been spotty both with the phone and with A2DP streaming audio) Sound processin…

What upgrades are needed to run a Sundown 2k? Some people say HO alt and some don't. What do you all think? Going in a 2005 Cavalier. Not trying to buy a HO alt if I don't need to. Thanks

digital audio DA6606C whats your thoughts on it? my thoughts is it is a well made amp and can take some beating.... but i have had problems with it clipping out...

Alpine Vpower M-650 I have seen this amp at bestbuy and on crutchfield for $250+ It is only 650 watts supposedly and not 1ohm stable So i am wondering is it over priced? am i missing something here? a hifonics amp is half that price and double the boom I am asking because my friend has one and we're trying to find a good 12" to put it on http://www.crutchfield.com/S-S36Z13yjYlN/p_500MRPM650/Alpine-MRP-M650.html

I have been thinking about making some quality Big 3 kits, and just want to kind of take the forum's temperature about the idea. Ordering will be easy, simply give me the three lengths you need from mounting hole to mounting hole(for me, this will = terminal hole to terminal hole). Here's a rundown of the parts/process. 1) Wire being used will be the new black Audio Technix 1/0 CCA wire. 2) Terminals will be tinned copper to resist corrosion. 3) All wire/terminal connections will be crimped via a hydraulic crimper for a connection that will never wiggle loose or back out. 4) All connections will be finished with some black heat shrink tubing for a clean look. Do you guy…

http://forum.elitecaraudio.com/showthread....18&pagenumber=1 (for those too lazy to click the link) Boys, Zed just informed me that he needs 50 buyers for each amps and the production will take place. Price for Kronos: $700 Price for Leviathan: $1200 Deposit: $350 and $600 respectively. Who's in? http://zedaudio.com/Products/New-Amplifiers.htm KRONOS: This is a 175w x 4 at 4 ohms or 350w x 4 at 2 ohms four channel amplifier. It has identical front panel features as Draconia. There are pairs of switches added to the rear panel which allow the pairs of channels to be switched into a high current mode. This will change the above specifications to 2 and 1 ohm respectively…

Alright guys so this is my first "big" system. I have 2 soundqubed hdc3 15 d2's in a 10 ish cu ft box tuned to 32 hz. I have 2 soundqubed q1-2200 amps. I plan on strapping them. My mids and highs I got on lock so they're not important. I have a 180 amp ho alt by singer alternators. This is the absolute biggest he could make it. 1 xs d5100r under the hood and 2 xs xp3000's in the back. Nothing is installed yet I'm waiting for all my install accessories. Do you think I have enough batteries and is my alternator sufficient enough to handle 500 amps of max current? I'm waiting on my xs charger to come in to install everything because I need to fully charge my batteries. Also…

So I've been looking around for a while and am looking for a new head unit. I was looking for one with: - USB connection to charge and control I Pod through head unit. - Play's CD's well. - AM/FM radio with presets. - 4v RCA pre-outs My price limit is $300. And what I've been looking at are: - Pioneer DEH-P7200HD - Alpine CDA-9886 - Eclipse CD7200 mkII Have you used any of these head units, & which one do you think I should get? Thank you, And I'm up for any other suggestions.

Which is a better amp? Apsm 2500 Apcl- 18001d Both have good power ratings for my sub but what's the difference? Which is more efficient? Just trying to decide which to buy.

I currently have 2 batteries in my car. I've been using my ctek 3300 to charge both at the same time... Shizz mentioned something about not charging batteries at the same time because of possible issues with rest voltage differences between batteries. If I want to charge mine separately, could I just disconnect the positive(charge) wire and leave the ground connected when charging the batteries so they are charged separate??? Does this make sense?

Would going from ~130w to 300w each amongst 4 infinity 1252w's be worth the strain on my car's electrical system? It would only be a difference of 3, maybe 4 decibels. Would a high output alternator be necessary for 1200w, as well as a deep cycle battery? Or should I stick with the setup I have, and not have to dump around $500 into the electrical system of a car I don't plan on keeping? I could always take my battery, so I might get that if it would make a difference on it's own. My lights dim really bad, but even when I step on the brake or roll up a window w/ out the stereo on. My grounds are good, but perhaps my headlight ground is bad? Sorry, I know this ended…

Who can I talk to about having a Treo 750.1 fixed, I've been told THE fets are fried.. I'm not 100% sure if anything else is fudgeed or what, but I'd like to see how much it'd be to get fixed, rather than buying another amp.

I ordered a hifonics zeus 1800w amp. The spec sheet online says it uses 4ga inputs. I feel like 4ga is rather small for an 1800w amp. I know I can get wire reducers, but could I just run 2 fuse holders, and on the rear at the amp go down from 0ga to 4ga? Or should I just run 1 fuse, and solid 1/0 run to a reducer?

looking at replacing my two MA Audio HK802sx Amps for two hcca 2500's possibly...... http://www.hifisoundconnection.com/Shop/Co...sid/0/SFV/30046 I know this company has been taken over by directed elelctronics...and all the orion products arent what they used to be but....ive installed several of there new Cobalt series amps and speakers in customers vehicles and they all seem to perform very very well for the price.....so i was hoping someone had some insight on there new hcca 2500 model...... The amps i have now work great, but i only had one amp at first......then i upgraded from 8 memphis 12's to 4 Fi SSD 15's w/ bp power option and copper coils Dual 1 ohm and added …

Noticed one of my 40 amp fuses on my 1500d is fuzzy looking on the left inside part of it. I'm not trying to damage anything, so I'm wondering what's the proper way to remove a fuse without causing anything else to break? Thanks, Nick

I have scoured the internet last week and found nothing that can do this for real... I only found one amp, can't remember the amp but definitely could not do 200w x 4 @4ohm with a 60A fuse... I am trying to find an amp that can do 200w x 4 @4ohm so i do not have to get 2 amps that can do 200wx2 @ 4ohm. It's a space issue. Anybody know of such? And i do not plan on getting the 15K rockford amp.

i just got my head unit installed and i was wondering can i install a portable hard drive into the usb port to play my music

What does clamping an amp mean? "my amp clamped at 2800watts at 2ohm 13.8 volts" does that mean he stuck it in one of these, and it put out better?
