Amplifiers / Head Units / Processors / Electrical

I have a 3 way electronic crossover 18db slope and rta on my Head unit. I have 3 6 volt preouts front, rear, and subs, I have my tweets run off front channel and my mids ( 2 5.25's ) off the rear channel and the subs my question is. I know what freq the crossover points are, but I am not sure what Q is on the crossover, I can adjust the freq range and the q of the crossover. And I think I may be doing my high and low pass on the bandpass portion incorrectly. I have the high pass set to 3500 and the lowpass set to 100, was not sure about the Q so I left it alone. I have not done anything with RTA, I messed with it some but could not tell a real difference in positioning b…

Anybody on the forum fix amps? I hav a shok industries II. Got it in a trade amp is blown

I'm looking at an alpine class D sub amp and wondered if anyone has used them. Its the smaller 301 but might maybe be large enough for me not sure. Anyway, it looks to have a parametric eq in it even...that would be nice. Anyone used them? I guess I'm wondering if one would work ok for my sort of SQ system, instead of an older class AB that takes more power. My kicker class d seems to work ok, but assume the Alpine is better quality yet.

I have a chance to get some Kinetik 16v batteries for about 150 bucks from a local shop.. i wouldnt be running on 16v but on the 12volt side, should i get them? they have 65 AH and are apparently very good. any questions or comments?

1st off let me say that a dd1 is not currently available anywhere around me at the moment. And I just got my system installd so I wont be able to afford a dd1 for a month or 2. Also no shops around me have a scope (dont ask me how they set their gains). So I have to temp DMM set it. Question is ive read alot of people saying to set it to the HU preouts which would be 2volts. Even on volume 29 the gain is pretty much all the way down at 2 volts. Or do I set it from the watts/ohms chart that ive seen around the web? Which would put me around 38-42volts? Which of the 2 should I go by? Also what setting do I set the DMM to, I know its Vac, But is it 200, 2000, ... ? Any info …

what will i need to power these two beasts?

I just bought a couple of SA E10's with Dual 4ohm coils and they will be going in a sealed enclosure. What class D amp would you recommend for around $100? I prefer this route so there are no electrical issues with my son's older car. I also have the option of running some old school amps (Lanzar Opti 100-1ohm stable, Lanzar Plus 100-1/2 ohm stable, Lanzar 240-2 ohm stable) I don't like the idea of using my old amps because I don't want them stolen as they are not easily replaceable. Another option is a new Boston GT2200 or a GT2125. I can buy a new 2125 for under $100 but don't know if it will run these E10's well. the GT2200 is more than I want to spend for him and not…

Ok I got to thinking the other day about the way I wired my sub to my amp. I am sure this has been discussed before. But I have been unable to locate the answer. If it has I appologize now. The sub is an Alpine SWR-1222D and the amp is a MB Quart Discus 1000.1 Monoblock. The way I have it wired now is in parallel to 1Ohm with one set of wires to the amp on the outer positive and outer negative terminals. According to the manual that is for single svc sub. Is that way ok or should I physically wire each coil straight to the amp. As the amp automatically parallels both sets of terminals which would make this a 1Ohm load as well. Which way is better the way I h…

So me, the gf and the little one are going on a trip next week and I wanna get my DVD working in my truck so the little one can watch DVD's. Now, I wanna bypass the parking system feature on it so the little one can watch a movie or 2 on the highway. I know this is illegal but its only for this trip. We usually use the gf's vehicle but hers in the shop for warranty work. Whats the easiest way to bypass this?

long story short. stupid on my part. but i am in the process of getting a thing built so i can hold my box and amp down, without having to screw into the seat or false floor. so for the time being it is freely hanging out in the back of my jeep. the sub slides around alot, the amp barely moves. well saturday night i was driving around with frineds, and went to a part of town i rarely go too, and witht he fresh snow on the ground i didn't see a speed bump (no signs...) well i hit it and i looked int he reiw view mirror, i saw my sub slide, but not really go in the air. i heard my tool box fly up, and i'm assuming my amp did too, as they were by eachother. after it landed,…

A buddy of mine just got two power acoustik demon 6000d series amps. I looked them up and they said they would do 3500 @ 1 ohm and 7000 @ 2 ohm when strapped. I've never seen per heard these amps so he enter to know if anyone has any knowledge of about them. I thinly its very sketchy ratings for the price. Anyone have an idea?

My buddy has a charger its a "smart charger" so he says will charge a 2v something charge its like the slowest charge he says. It has every abbreviation on it but agm. Will it work for my 3100?

I have a really small 2-door car. I need a ballpark on how many ft of 1/0 to buy to do the big 3.

I need an Alpine head unit that'll work with 3 amps ( 2 sub and 1 mid/highs ) I'm thinking about, IVA-D106 http://www.alpine-usa.com/product/view/iva-d106 Opinions?

ok im runnin low on resources to complete my install..so i was thinking of ways to save some money... Im going to be runnin 2 amps...a BX1000D and an older PG QX4150 fuses are 60 and 40 the Brutus takes 4 gauge while the PG takes 8 Now heres my question...i was gonna run 1/0 from the batt to the distroblock then split it into 4gauge and 8 gauge Now instead im thinking of runnin 4gauge from the batt then split it at the distro block into another 4 and 8 gauge Anyone against doin that?

Dave maybe you should sell the PG for this beast but any way here is the link to the page on their site: http://www.soundstream.com/sub/products_amps_xxx.html

so i got an iraggi alt about a month ago and the battery indicator light(on the dash) was on the whole time, it died on me after 5 days, so i sent it back to iraggi. i installed a stock alt, everything was perfect, the batt light wasn't on. then i got the replacement alt from iraggi, got it installed and now the batt light is on again. the voltage is about 14.2. upgraded big 3 is this normal? its for a 2000 ford explorer sport 4.0L SOHC 240/165amp Amputator series Iraggi Alternator Optima Yellowtop(under the hood) Kinetik hc2400

Would i need a new battery and alternator to run 1500 watts...i have a rockfor fosgate 250.2 and have it bridged to 2 ohms i'm aware that i'm not suppose to do that but not too concerned about the amp i just need something to push the 10's behind my seat...but i am wanting to run a 1000 watt 1 channel amp to power a 15" Fi Q...please help

right now i have a cheap 20 dollar line out converter. As you turn up the volume it doesent get any louder, and i know im not getting the full 1200watts. All my electrical is good, my voltage stays at 13v. Are you guys familiar with the jl audio clean sweep? I dont want to get a headunit. All i want is when i turn up my volume it gets louder and louder, right now if i turn it up it stops getting loud, it stops after a certain point. my volune is 30max and when i put it to 16 it doesent get louder??? my current equipment. 12bl fully loaded and sundown sae 1200d. all 0 gauge I have a 15btl and a sundown sax 2500d on order.

I just had the 5030 installed in my girlfriends car and I need advice from someone that has experience with this deck on the settings. I have 6 1/2s in the front and back running off the deck and a 750 watt Kicker amp powering a sealed Icon 15.

i took my equipment out of my car to diagnose a problem. while it was out it was stolen. so now i am stuck with factory power. the problem now though is, the factory system had some issues when i bought it. at a little over half volume the sound from the tweeters cuts out when there is a louder sound.. like a yell or.. scream. or just louder singing. head unit? or amp. 03 z4 by the way

Tracy, I saw some info in here the other day about the newer amp lines. I was hoping for a refresher and also wondering along the lines of AB power... 750X2 @ 1 or 4 Ohms or so, maybe 1500 @ 2Ohms. Basically I mant alot of controll, like one of the new lines seemed to offer. I am going to be powering 2 Brahmas (I needed a little more umph ). I am hoping to keep them in a foot each so power needs to be about 750-1100 or so per driver. I like the Cadence Z1500, or a pair of Z9000s. I am even kicking DEI around (2400D) but it is a D amp. I really want an AB. Also I was wondering if you might hit me some rough prices up. Thanks Bud, Seth

A quick question I am planing to buy this wire from knuconcepts when it asks me to choose fuse size what do i pick right now i am running a dc l4 12 with an aq1200d. i want to upgrade in the near future with 2-3k watts:) the question is it fine if i get the 300 amp fuse? http://www.knukonceptz.com/productDetail.cfm?prodID=KFX-PK0

Just out of curiousity, for those that are running batteries in the trunk, how many are running them without some kind of isolator? Are you seeing any issues? For those that are running an isolator, what are you running and where can you find them? What kind would you recommend, if any? I am thinking of running a Yellow Top in the trunk, or possibly a Kinetik. If I went with Kinetik, which battery do you recommend (besides the 2400 which I think would be a little extreme for a daily driver, but maybe not)? Thanks in advance.
