I have an Alpine headunit not sure of the model at the moment. I have all 4 ohm speakers hooked up rite now. If i were to hook up in exaple two 8 ohm speakers.. Would i mess up my headunit fom the diferent impeadences? Maybe a noobish question but i've never tried it. Thanks for the help.

How would you figure this out? Ac/dc / ac/dc? Running a mmats D300hc in a 2 cu. Sealed enclosure. Not supposed to run the mmats below 1 for daily driving, so want to know how I'm doing so, is this the cheater amp its made to be? Drawing lots of current lol, voltage drop. Don't want to dmg the amp, rewiring it to 4 and making a larger ported I guess.

i recently bought a fi bl 15 dual 1 ohm sub and in desperate need of an amp with 0 guage connectors

I have an AudioQue 1200 running my single fully loaded 10" FI Q. Wednesday omw to school, my amp cut out. I took the inline fuse out (which looked perfectly fine) and replaced it (i use 100A fuses). Thankfully my amp started working again. Thursday omw to school same thing happened. my amp cut out. This fuse was definitely blown. I immediatly ordered a circuit breaker because I was tired of replacing the fuses (the audio shop where i got the stuff installed at charges me $5 for a fuse). I went to Advanced Auto Parts store and bought a 50A fuse hoping it will hold me untill i get my circuit breaker. When i put the fuse in the fuse holder, the power light on the bass…

Long story short, I'm keeping the factory Nav/HDD/BLUETOOTH/IOD/DVD/MP3 head unit in my '11 Ram. I installed a PAC OEM-1 (OEM-CHR3) for the plug and play ease plus remote turn on from the can bus system. My question is on setting the output levels of the OEM-1. I installed the OEM-1 and just turned all four outputs on the LOC all the way up. Is this correct? Is there any reason I wouldn't want them all the way up to feed the amplifiers the highest signal level?

Does anyone have any experience with these amps? Are they reliable? I just bought the little 500.1 to try out in the sq oriented install. I bought it because its so versitile with its wiring options and I got it dirt cheap but I havent heard anything about its relliablity.

Well, it is finally time for me to get a new head unit for the Bronco. I really like the Alpine cda-7893 that is in it now but it's from 2002 and is cd only. The Alpine skips like crazy now when I try to get some decent bass going in there and I need to begin testing for next season so I'm going to purchase a new unit with usb. I'm looking for some suggestions on other units that I may have overlooked and some opinions on the few that I'm already interested in. Here's the list of requirements: 1)Single DIN 2)3 preouts 3) USB (front really preferred) 4) Ability to play cds Here's the list of units that I'm thinking about: Kenwood KDC - x895 (I like this one and will probab…

So I plug in the ground and it fine. Then I plug in the power and it starts to fry. The same thing happens in vise versa. What could becausing this? He has a 99 camry, his amp is a Hifonics Titan 750.2.

Hi im looking to buy two Fi 12" SSD's and want to hook them up to only one amp, is it possible to wire them at 1 OHM?

So this may be a noob question but i need to learn car 08 grand prix gxp with mechman 270 2 xcon 12's in 4th order bandpass I can purchase two amps vibe blackbox bass 5 that put out (each amp) 1500rms @2ohms I can get both $750 total Or I can purchase one amp sundown 3500d that puts out 1750 rms @2ohms for $800 Would I benefit from getting the two amps and having one to each woofer or would the single amp be my best thing to do?

I had the Addictive Audio 10.4 (115x4 @ 4 ohms) screwed into the box playing the 2 Selenium 6W4Ps active fine for a while. I started getting a static sound from the speakers, when I noticed that nearly all (7 out of 8) screws that hold the casing of the amplifier to the internals had stripped out and was barely hanging on for dear life. I took the amp off the box and took it inside to have a look, and didn't see anything out of the ordinary. That being said, I have no idea what I'm looking at, but there were no loose wires, no solder points that had failed, etc. I gave it another try and set it on the floor of the truck beside the AQ2200D, wired it all up, played fine for…

Looking to possibly upgrade to 2 15" zcons and was looking at the bc5500. Just wondering what kind of electrical people were running to these. And how the felt about that amp. I have a 320 amp DC alt with 2 yellow tops in the back. I think I should be fine but can add more yellow tops if needed.

Hey does anyone know anything or have an opinion about this amp

I currently have a Kenwood KDC-248u head unit and I think I want to upgrade it to something a lot better. Not exactly sure what hu I want so I am looking for some suggestions. Budget is $400 but I definitely would like to get something cheaper if I can. Thanks -JP

hi guys have a question. i went threw some car audio stuff my brother owned back in 98 before he pass away and never knew about this stuff tell now. and i see he had this rockford fosgate 4040 dsm 4 channel amp that still work's and was told that this amp is a beast. but my question is what is the true rms rating per channel on this amp.

http://www.parts-express.com/pe/showdetl.cfm?Partnumber=265-081 Could that amplifier reliably produce at least 30w rms per channel run as a sub amp? rated for a 4ohm minimum, but with plenty of reserve i'll be running it at 2ohms.

So while doing research on the 800/880's I came across the 9800bt. Now from what I can tell they are pretty close in head units with the main differences being. 9800 - color display, bt 800/880 - active capable, left and right equalization, im sure some more tuning options im forgetting. Are there any more major differences in these 3 units? I do know they both have burr brown 24 bit converters and 5 volt outs and lots of tuning options. Now at the moment I'm not going to be running active. Eventually I want to learn how to properly go active and all the tuning that goes into making a good sounding system. Any opinions? Are there any more major differences in these 3 uni…

I'll be running a Fully Active front stage and am intrigued by what options Sony's 2011 headunits have to offer. Does anyone have any experience with it any of them that can comment on Sound Quality and Build Quality. The one i'm interested in is: DSX-S310BTX http://www.crutchfield.com/p_158DSX310B/Sony-DSX-S310BTX.html?tp=5684#details-tab http://store.sony.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10551&storeId=10151&langId=-1&productId=8198552921666372151#specifications 7 Band EQ Time alignment/LowPass/HighPass 4 Volt Preouts (front, rear, subwoofer) Bluetooth Pandora Radio Capabilities Front USB 17x4 rms (wish it was more but that's what i get …

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'm looking at maybe picking up the N4 which is Massive's new Nano line. Was wondering if anyone has experience with the Nano line. I've had older lines of Massive amps and I think they are fine, but never tried the Nanos. Wondering how hot they get.

hi everyone have a problem and need your help i have a lanzar opti drive amp and i hook it up all right. the amp shows power but puts out no bass to my subs. now when i turn off my car the amp still stays on even when i pull out 1 of my fuses in the amp,

Just as the topic states. For example, what would be the 4 ohm rating for a AB 1100.1 be? I know on their Website it says or shows what it does at 1 Ohm, but what would it do at 4 Ohms? Is there a Formula to this Madness or do you simply divide the RMS of the Amp by 4 to get the 4 Ohm Rating? I know I am going to get some Stupid answers, BUT I would really like to hear Educated and Smart Answers. Thank you in Advance my Fellow Bass Heads. Also if you know the 4 Ohm Ratings for your Amps for you Sub Stage, would you kindly list your info in this Format. Make: Model: 1 Ohm or whatever Ohm Load your Amp's RMS is rated at: The Amp's 4 Ohm RMS Rating: Again Thank you in Advanc…

Hi everyone im going to be running a kicker component set for my front stage and in my back seat i will have selenium super tweeters the component set is 4 ohms, but the super tweeters are 8 ohms, the component set is 100rms per pair (driver and tweeter) and the super tweeters are 100rms each. i plan to buy a sundown 100.4 now for the speaker system. is it ok to run everything per channel? what ohm load would everything be? i assume 4ohm and is that ok for the supertweeters? this all sounded good in my head but now physically its lookin a mess lol... please dont judge my decision to get supertweeters, i know i will enjoy them.. this would be my first build with supert…

I was wondering if somebody with personal experience could tell me what they thought about the sd8k and 12k amps. Thanks
