I HAVE A JVC KW-AVX830. The usb port is a cord that comes from the back of the HU and it it hard wired to it. I have not had the thing a year yet. It was working fine everyday. Until yesterday. I plugged my phone.in and nothing. Tried my thumb drive too. Same thing. I'm pretty sure nothing has changed.as far as the set up goes. Pulled out the HU today and wiggled the wire around a bit and still, nothing. Kinda P.O. about.it. I just got hold of a bunch of supposedly high bass song for.my thumb drive. Any thoughts ?

well i got my sub in today for my little mini build im doing and now i need to decide what amp i should go with to power it. the sub is a Fi SSD 12 D1 with BP cooling. I was thinking of running around 900-1000 rms to it at 2 ohms. So the question is what amp would you guys think would be good for this? The budget on this isn't much. probably around 200-225. thanks

Hey guys i have a question about using a second battery. i have a 95 Caddi stock alt. iterstate battery up front. i have done the BIG 3 using 4ga. The amps im running are the R/F P-400.4 at 4ohm each chanel and the R/F T500.1bdcp at 2ohm on two 4ohm svc 12" Dcons. i have been looking at the XS battery's. And would like to know if i would benifit from running one, and if so wich would be seggested. thanks for the feed back

Does it really matter what RCA cables you use from your headunit to your amp?

So I just bought my 10" BL and im not sure what amp to get? What do you guys suggest? Budget is around $200

From those who have experience with these batteries- I need a total of about 4000 worth of their model numbers... For instance 2 hc2000s or 3 hc1400s, get me? Ok, i got a small area to put batts in, i had emailed them asking if i'd be all right if i ran 6-7 HC600s in the back... They told me no, it wouldnt last that long before they were completely discharged. They said the HC600\800 are like large caps, not long-term batteries due to their short reserve time(too bad they dont post reserve time on their site!!!) So, i called them up just now and got ahold of someone on the phone who sounds like he has less experience with them than i do... so i come here. For daily driv…

I'm looking at possibly running three 4 ohm subs, which would give me a 1.34 ohm load (of course, you all know this already ). How much power would I lose if using an amp that does its power at 1 ohm?

i need to wire my sub at 2 ohms. the blue line on the right that goes from 1 of the positive's, to 1 of the negative's, is that 1 piece of speaker wire or is it both that i twist together and put in the terminal? like speaker wire has a positive and negative, do i separate it and only use one side, or do i twist together and just use both? hopefully my questions makes sense. thanks guys.

i know the older soundstream stuff was good, but I know nothing about the edge series or picasso series class D amps. i figure they put out rated power, but are they still considered quality? I need a 1ohm stable amp, and soundstream has some good prices on ebay...

I have spent an hour on google searching trying to find a neon light controller that will flash to the music using a rca cable so the neon flashes to the music and not people talking. I have seen them before but i cannot seem to locate one now that I wan't to get one.

the alpine 9887 vs the pioneer p880prs... which would be the better choice? or is there other worthwhile h/u to look into... budget is 300-550 as of now leaning towards pioneer since ive never had a problem w/ my current one

I have had one of these guys sitting around in my room for a while now. The only info I've ever really found was this thread from 2006. Anybody have any other info?

Just got this fold down face HU today for a tank of gas and 5 bucks. It needs the code for it and my local Kenwood shop wants 85 bones to send it to them for the code. Can someone help me??? I could use a code or someone who can help me here. J

i was wondering if i will be able to hook my batteries up like this or is the only way is to daisy chain them? - - i know this is the rite way, but just want to know if its possible to do it the other way reason for askin is limited on wire at the moment

I bought a Sundown 100.4 refurb from DB-r a while back while it was on sale. When i got around to installing it, it was blowing fuses on the distro as soon as you hooked it up. So I sent it out to DB-r Tuesday before thanksgiving and I recieved the amp back TODAY (1 week and 1 day later). I am completely amazed with it being the week of Thanksgiving I received the amp back so quickly. That includes shipping time BOTH ways. The whole time it was out DB-r kept me updated with emails. I just wanted to give credit to DB-r for the excellent work they did. :bigclap:

I have a new SSL amp that has power coming from the ground on the amp any help would be appreciated

I have an Eclipse CD-8053 CD player which I love. It have a built in Crossover, However it can not do everything I need. I need a outboard Crossover that will work in conjunction with the Eclipse r all by itself to control a 3 way or 4 way system I have a SI Sub CDT EF8 Midbass CDT ES520 Components. Now either I need to break the audio line in 3 spots and use 3 amps and let the Components Crossovers do the work between the 5.25 driver and the tweeters, Or I can buy a 4th small amp to run the Tweeters off the new crossover. My Main concern is that its adjustable, and will not introduce any new noise, in other words a SQ piece! Let me know if you have any suggestions. I …

ok i know there is a topic here somewhere on this but i have searched using keywords and didnt find what i was lookin for. i would like to know what are suggestions to correctly power a sundown 3500. it is not s competition vehicle jus a daily driver. the speakers will be 4 fi ssd's ( i already own them) run @1ohm. most likely this will go in my ford escape which already has 0ga upgrade, kinetic 2400, batcap800 for electrical. i know i need an alt so i will get probably one runnin at 14-15v 300-400a. i might only compete once or twice but this is just for me to blurr my vision when i'm feelin it. how many batts should i add after i get the alt?

Just wondering some of your thoughts on the Powerbass series of amplifiers. Good quality? Underrated, Overrated? I am thinking of this being it is cheaper.... or Sundown 1500d. It is about cost, but reliability It will be put on a Fi BL 15" in a 4.0cuft box tuned to 32hz. Powerbass 1500d.

I bought 2 IDMAX 10" D4's CHEAP, was putting one in the wifes car and selling other but she wants to wait on her stereo. So I am putting both in my expedition. I have never had any ID subs and these are only ones I have heard. I listen to mostly Rock, metal, some country. I have read to do sealed mostly and some say ported. I was either going to run a sundown 1000 or alpine pdx 1000. Any suggestions on these? thanks

Hey, Recently my MB Quart DSC4125 bit the dust and waiting to see if it can be fixed under warranty. Anyways, I have an 8" orphan from Sound Splinter and was wondering what Amp would be good to run it? Either Mono(for sub) and a 2channel to run a pair of Infinity Kappa 682.9cf's or a 4 channel amp again so i can run the sub along with the speakers. Having a hard time finding an amp for a 6ohm woofer that's sweet spot is at 500W. As for budget, not looking to get crazy expensive, say if possible around $300. Just need to be pointed in the right direction. Thanks.

I'm going to hook up the rubicon 702 to an FI SSD12 with copper coils in a sealed enclosure 1.6 cubic feet. This amp has 700RMS watts. Now what should I set the low pass crossover frequency to? Should I set the subsonic filter? If so to what frequency and should I also set the boost?

I just recieved a used nine.1 Is there anyway to test it here at home to see if it works? Thanks

So I am attempting to install my upgraded alternator and big 3 this is a first time for me with both situations. Everyone from here has been super helpful so I was hoping you can bail me out since my car is in pieces. I have currently removed the original alt and put the singer alt in that I purchased. I have not connected any wires yet this is where my confusion has started. I have located my grounding wire from engine to battery and will upgrade it which is one of the big three. Now the other two is where I am getting confused. 1.The alt I purchased from singer has an upgrade to increase my voltage and the device he put on has will not allow me to re attach the two c…
