Amplifiers / Head Units / Processors / Electrical

Hello SSA I am wanting to know what are the subwoofer settings on the head units supposed to be set at? I am trying to get the most possible but I'm assuming if they are turned up all the way up I'll be clipping? no really sure where to set them at. Anyone please help lol

Allright guys, I was working on the car last night, and re-doing my grounds and re-running everything neatly...and what not...and put everything together nicely. I got done, and now my amplifiers stay on constantly even when I kill the car. And my headunit will not turn on. I did pull the H/U but I checked everything behind it, and nothings loose or broken. If I un-plug the Remote wire from the amps, they turn off.....seems like they are getting power from a hot source, but the H/U will not come on. I didn't let anything touch in the trunk, or anything...no fuses have blown...no loose connections anywhere. I'm stumped .....never ran into this problem before....has any one…

so my buddys had his amp unhooked for a couple months and today i went over to his house and just reconected the power wire and fuzes because thats all that he had unhooked and when we crunk the car and turned the system on his subs just let out what sounded like a 40 hz tone and nothing else his door speakers were playing the song but his subs were just going non stop the system in question is a power acoustic 820 2ohm mono ampand two memphis tens white and black i havent seen the back of the so i dont know exactly what they are someone help me please

alright ive been searching for used 2400s and d3100s and i just gave up because i just found this deal. figured i would give them a try. i already have 10 hc2400s and 1 d3100. http://www.powerhousebattery.com/cgi/displ...em_num=UB121100 i found out it was cheaper to buy the batteries 1 at a time then buying all 5 at once so i did 5 seperate orders 205 SHIPPED EACH 205 was in my price range so ill give them a try.

Hey guys, I'm pretty new to the forum, I've been lurking for awhile trying to learn as much as I can. Anyways, I've had a 15" Memphis sub and a Memphis Power Reference P200.2 two channel amp for awhile. Lately my sub started to sound like it was fixing to go. I found someone selling two Memphis 12s in a box on Craigslist. I went and met the guy and hooked up the speakers, and they sounded good, so I paid the guy and started to get on my way. The speaker wires this guy had for the 12s were crimped and part of the metal was exposed. I went to push the box the rest of the way into my Explorer, and like an idiot, I let the exposed metal on the speaker wires make contact. Smok…

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

http://www.soundsolutionsaudio.com/store/products/Incriminator-Audio-I-Series-6.5%22-Components.html So I bought a set of these. Just wondering what peoples opinions would be on a amp thats roughly 75x2 (figured that cus it seems like it'd be more common that 85x2). Size isn't really a problem. Looking to spend 50-100$. Know thats not that much but really just want something better than running them off the head unit. So what do you guys think?

So awhile ago I had a battery isolator installed on my tahoe and I'd like to remove it...It's bolted onto the plastic fuse housing, as in inside the fuse housing there's nuts securing the bolts... Any idea how to get to those nuts so I can remove it and put a fuse holder there instead? Thanks

The following is going to be presented as Company A and Company B to prevent biased responses. I have been told a LOT of information from 2 different alt specialists about my car so if this were you... what would u do? My car is an 07 scion tC. It uses a special alt that uses a hairpin stator. At this time, there are only these 2 companies that offer alts for this car. The design of the alt itself- it uses square windings to fill more of the gap inside for increased efficiency and to get as most amperage out as possible as well. Now, here goes the specs of each company and what they say, u make the call... Company A- Offers a 300A alt, 140A @idle, $700 warrantied for…

Does anyone have any experience with these? Or the line. I used to run The old SPL's SPL160s and the Rubi 1002. Did very well with them. I know epsilon owns them now. Do they do rated, Efficient, Will they run at .67 or .5 Ohm? any and all help is appreciated. Price wise and Numbers they look good but after Carrying and running American Bass and Power bass Amplifiers it's kinda hard to deviate.

I'm looking for broken amps that anyone is parting with. I'm a newbie tech looking to fix amplifiers.

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!

My buddy gave me an idea on how to mount my amp, but it will touching the batteries...will that harm anything when the amp is on?

So I am trying to figure out which LOC is best. I know about the 3SIXTY, CleanSweep, and new MS-8. I'm not really looking for anything that complicated. I want to retain my factory steering wheel functions, sat. radio, bluetooth func. etc. I really believe in the modo, K.I.S.S.=Keep It Simple Stupid. Because of this I was dead set on the Audio Control LC6iBUT just found out about the re-Q5. Now I'm unsure which is best, and more importantly best for me. 1st the re-Q5 is just a bit more than the LC6i but still with-in my budget. The fact that it is said to even out the bass output at all volume levels seems like it could be usefull if the factory h/u tunes the bas freq. do…

Hey Guys! Alpine has came out with a new PDX series! They look pucking sexy as ever Few Copy and Pastes from their website. Power Management Processor PDX amps incorporate Alpine’s new Power Management circuit. The Power Management Processor controls all aspects of amplifier performance, monitoring voltage, temperature and output to ensure uninterrupted power output for non-stop listening. If the amp gets too hot, the Thermal Protection circuit kicks in and gradually decreases output power until it cools down. Once cool, the power output automatically increases back to the previous level. If the circuit detects a Low Battery condition, it will gradually decrease power …

so i called to see how much everything was gonna cost plus the 3yr warranty and they said they were all sold out but the website said they werent....anyways they said they should have some more in a couple of weeks,i knew that was gonna happen with them having that price on that x889....now i dont know if i should wait to see if they get more or if i should just pay the extra $50 that the closest other store has it at.....but then again the 8445 is around that same price so i dont know now,dammitt everytime i make a decision something happends....grrrrrr LOL

i found two 75 ah sealed cells for 119 each.... so does anyone know of a cell or maybe 2 that will be the same price with just as many amp hours shiped to my door? im also gonna do another run of 0 gauge and maybe running them stright to the alt.... im also thinking about getting the mising link high setting to 15.7

Can i wire my 4 subs to a Sundown 100D and give around 250RMS to each sub? Is this safe? Would it look like OPTION 1 from this: http://www.the12volt.com/caraudio/woofer_configurations.asp?Q=4&I=22 And for this i wuld get 4 Dual 2-ohm.

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

Is it bad to lose strands of power wire overtime from lets say, disconnecting the wire from terminals and clamps, or even accidentally slicing some off when cutting away at the insulation? Do you lose conductivity and/or lessen amp load of the wire? Also, would using a coupler to add on to an existing power wire to make it longer be okay to do? Or would I have to run a new longer wire to the size I need?

Here is my problem. I know the out put values on the amp @ 2ohm(115wrms) and 4ohm(75wrms),what I don't know is the output @ 3ohm which is waht my comps are. Should I assume a midpoint? And effectivly gain down to say 85w(100wrms 3ways and 90wrms 2ways)meaning figure voltage for 85w @ 3ohms and set accordingly. Or do I just need to get an o-scope and do it on a bench?

Ok well right now i have a pair of Polk db651's in my front doors, and my stock bose speakers in the back (they barely put out any sound at all that i can hear). I have a sony gt620ip (not the best but its what i have). Now the question is... Will my front speakers get more power from the h/u if i disconnect the back two speakers?

hello i need amp wt these specs for my jbl gt 4 1000 watt 2 woofers please suggest me a good a amp 125W/2 ohms bridged mono (bridging into 4 ohms). Amp should have 4 channels each rated for 125W/2 ohms.

I have a head unit that puts out 4 volts, is a line driver neccessary? Am using the AQ2200D amp if thats neccessary. Thanks

Hey guys. once again i'm having another problem..my head unit isn't getting any power. I went to instal my voltage meter that i got today and then the no power problem started. I finished installing the voltage meter and everything was working fine. I pulled the head unit back down to put the RCA cables back in and it seemed like the music volume started to get lower and lower. I finished everything and picked the HU back up to put it back into the dash and everything just quit working. I thought that maybe some wire just came loose so i checked everything and it all looked fine. I just cant figure out what it is. Everything is wired together just like it should be, exce…
