I have a jl 500/1 gains are supposed to be set at 31.6 v ac. I have tried two different decks at 3/4 volume with bass flat and with the gain turned all the way down Im getting 40 volts using 50hz signal at 0db. the sub 12w6 sounds loud with the test cd but barely audible with music. Is there anything obvious to look for? thanks Todd

1) Low voltage. Most car charging systems aren't equipped to handle the extra strain of amplifiers without some sort of help, if this is the case you may need to add, a capacitor or battery. 2) Blown sub. Sometimes when you blow a subwoofer, it can take your amp down with it, most amp's will go in to protect before this happens, but not always. 3) Over driving the amp. If you max the gain, and bass boost on your amplifier, you can cause all sorts of problems, including blown fuses. 4) Loose or bad connections. Check your connections to the battery, and ground, sometimes a loose connection will play, but cause your amp to over heat by working to hard to produce it's power.…

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…

So I have a friend that wants to replace her amp and sub that came with her 07 Ford Edge. The sub sucks and the amp just doesn't have enough power for her. Is there a way to install an after market amp wihout having to buy a processor like a RF 3sixty or AudioContro DSP? Sorry if this is a silly question, I would like to tell her all her options. Thanks.

So while I was deployed to the middle east I acquired my car audio equipment. But now I'd like to know what amp alternators and batteries would work best for my system. I'll be running a 15 BTL off of a Soundstream DTR2200 which should push 2200 watts to 1 ohm. I'll also have a 4 channel Soundstream amp pushing 100 watts a piece to 4 6.5s in the doors of my Tahoe. It'll be ran off of a Pioneer deck. I've heard al lot about Optima batteries but have read mixed reviews on them. As far as alternators, I'm open to any decent brand that audiophiles have had luck with. Thanks in advance for the help.

I need a new pair of rca cables. Right now i have a really cheap pair of cables on it and they finally broke can anyone tell me some good brands or something? i was looking at a pair of monster cables but im not really sure what to look for in rca cables. Thanks

Do you guys think $425 for Sundown Saz-1500D amp is a good price. It's brand new.

I have noticed on DCsoundlab the difference in RMS output power from 16V to 18V 14.4V 4 ohm 900W x 1 2 ohm 2,300W x 1 1 ohm 5,000W x 1 1 ohm 16V 6,000W x 1 1 ohm 18V 7,300W x 1 http://www.dcsoundlab.com/5k.html These are the specs for the DC 5K. Now when the bass hits hard on my current 12V setup, I dip from 14.4V to 12.3V If I ran an 18V setup, and dipped to 16.3V while playing music, does that mean the RMS output power would dip at least 1,000 watts? Thank you.

ok, for setting gains with the DMM method, do i use 0dB tones, or can i get away with using, say -6dB or -3dB tones? I've heard recommendations for using as much as -6dB tone (that seems a little much to me) so i guess what I'm asking is how loud does most music get? does it regularly hit 0dB, or more like -3, -6, etc?

What would be a good touch screen radio that is bluetooth/mp3 accessible but does not play dvds? tryin 2 save a lil $ and a dvd feature is useless to me

What should I set the phase to on my mono amp if my 4ch. has no phase adj.

I was on Knu Konceptz and was looking at an In-Line Waterproof ANL Fuse Holder w/ Fuse and KonFUSED 2 Way Digital Distribution System. I was wondering what fuses i would need? i have a 1/0AWG power that will split into a 4AWG and 8AWG for the two amps. the fuses on each of the amps is 40 and 90.

so i own a duralast battery and and i want wondering if i could hook a optima gold top to it and have it work fine.. i asked in another post but it was not about this, i just got caught off guard with the original question

I just got a quick question. I just bought a Pioneer Avic f90bt for my 2008 scion tc. Now i just dont know what to buy for a installation kit. i found two kits on crutchfield but no reviews say that they fit for a scion tc. i was wondering if anyone had any experience with installing a deck too a scion tc or if they have use the kits that i have listed below. any information will be awesome. http://www.crutchfield.com/p_142SCN2059/Scion-tC-In-dash-Receiver-Kit.html http://www.crutchfield.com/p_120958202/Toyota-Scion-In-dash-Receiver-Kit.html?tp=3121&avf=N&tab=review if anyone got anything post up Thanks.

Ok, so iv been looking at power capabilities of wire sizes and im only running 4 gauge to the back of of my trunk. Now according to 12volt, with the length of the wire it will only be able to take around 600 watts rms of power. Would running my amplifier at 1 ohm, 1500 wrms, stress/overheat the wire? If this is true, maybe ill just run my amp at 4 ohms, (375 wrms) until i can run some 0 or 2 gauge wire once i buy it.

Iv recently blown my Alpine 1000.1 amplifier so i decided to replace it with an older PG Xenon 1200.1 i had lying around. I was looking at the control knobs and noticed it only has a Bass boost option, but no gain setting. Iv looked it up and its a bass boost knob for 45hz, 0-18db. I was just curious how i would go along setting this boost without a gain setting as well. Also, how should i set my deck settings along with this? I'm running 2 Alpine Type X 10" subwoofers in a ported box if that helps. Thanks -Mike

wonder if I should install my phoenix gold bass cube? we have to play a song supplied from the judges for spl and sq categories. You guys think it would make a difference?

Hi all, need some help, planning on installing my 200amp alt today. I see the factory wiring in my 98 GMC jimmy has an 8 guage going from (i think) alternator all the way to the fuse box then back to the battery? correct? now i have a piece of 4 gauge from a previous install around 16" long. the big question is can i just run directly from the alt to the battery? and if so what do i do with the factory stuff going to the fuse box? just leave it? or will that blow the fuse in the fuse box and cause problems? or should i disconnect it and just let it dangle? my battery is a 3 year old (weak) ac delco 680 c.a or c.c.a cant remember, and i did ground the battery to the frame …

Was curious if anyone knew if this would fit or be able to install in a 2005 jimmy. On crutchfield when I fill in my year make and model it says it cant be installed. This does not make sence to me as its not a huge double din or anything. The response only meen they don't have the kit for it? Maybe a kit for this model to work with a Jimmy doesnt exhist anymore? I don't know why a reg size deck would not work. car= 2005 jimmy 2door. No bells and whistles. standard, no steering wheel controls or anything. 1st piece to go with: Hertz HSK165 6.5 components for front. Fi Q12 in ported enclosure Soundqubed Q1-1200D at 1ohm Soundqubed Q4-120 for components.

Well I recently (2 weeks ago) purchased a Brand New Volkswagen GTI and it just turned 1000miles so it's time to play (I told myself that I'd at least drive it for 1k miles before tearing it apart.) Anyhow, I'm looking into processors, line level converters, ect.. I'd like to keep the factory deck, It's a in dash 6 disc with aux in and Sirius so I'd like to keep it for now (I've never ran a stock so this will be a new adventure) What I'm looking to do is just get some better sound.. I'll probably throw a five channel amp in there with a single 10 and leave the stock mids intact for now . Currently the stock setup sounds terrible... I've never heard a factory set sound so …

hi i'm between a second battery or an alternator both will cost around the same my only problem with the 2nd alternator is that my car is a piece of sh@t and not sure how long it is going to last me and dont want to put parts into it i cant transfer to a new vehicle when i get one my audio ive got is a saz2000d, 12" fi btl with daily, cooling dual 2ohm wierd at 1 ohm big three with 1/0 gauge stock alt is 110amp and main battery is a 24 ah canadian tire thing lol oh and my buget is 250-325

Can i use a standard charger to charger an agm batt with slow charge.

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…
