Hi Thomas! The surface mounted board has been damaged on your unit. They do not make this part anymore.. This is going require patience in locating another usable surface mounted board at about $75. to $100. extra plus the $119.95 already quoted. Do you want to authorize us to proceed? or at this point a $35.00 fee plus shipping is applied. (evaluation estimate fee). Please let us know your wishes on this repair. A repair time of two to four weeks is estimated after your authorization to proceed. arsehos quoted me 100$ Wrong So theres 60$ shipping $119.95 + 100 for parts. fudge i could have just bought another orion 2500D

My headunit is the alpine cde-102 and I got the alpine kce-433iv (full speed connection cable made specifically for my hu). Hooked the cable up to the rear pigtail connection, flipped through all the sources on HU and it shows nothing. If I set it to Aux, I can play music from the ipod but can't control ipod from headunit. So it's acting as a normal 3.5mm jack aux cable... I tried switching settings from Aux input ON to OFF and that only enabled/disabled the music from ipod, but still no headunit controls. My ipod is a touch 2g, I've also tried a ipod nano 2g, and no avail. Anyone have a similar problem or solution? Perhaps my cable is crap, but it seems odd for a new cab…

So... I got bored today and decided to write up equations for amplifiers, like loss, power with efficiency, how to find how efficient it is. basically, a variation of ohms law. as we all know, (V)olts * (A)mps equals (P)ower (V*A=P) but, in amplifier circuitry, this cant be used because amps have their own loss. so lets say our imaginary amplifier is 160A, running off 10.65 Vs, and has an effieciency of 77%. it'll push out around 1312.08 Watts. now to find each number, we use these numbers to find them. Basically, 1312.08W / 10.65V = 123.2a - 160a = 36.8 amps of current lost in the amplifier, 36.8 / 160 = .23, subtract that from 1 and we get .77. simple. I'm quite sure al…

DDAUDIO looks nice how bout the Price?

which do you prefer and why? Myself enjoy a good powerful 2 channel instead of a 4 channel.

Hi- I've needed a new alternator for a while and I'm finally starting to get my money up to purchase some upgrades. My 2000 Volvo S40 has a small alternator in a cramped engine compartment so most companies don't make alternators for it. DC Power and Ohio generator will make something for me, but I'm not sure which is the best scenario. I have an IA 40.1 (3600+ rms) and RF T4004 elite (~100x4). DC power quoted me ~$800-900 for a 270XP alternator. ~200 amps at idle, 270 max. This would be fine for my current system, but it's quite pricy and I could not buy new batteries this summer. Ohio generator quoted me ~$350-450 for a ~120A at idle (my stock max), and 200A max. Since …

tomorrow is quiver on the river, a TP usaci outlaw spl event..last year i took first in my class with a 145.5 using two 15" treo ss's (yeah, the ones that claimed a rear glass in a ryan built box, helped crack my windshield[rock chip]) using a memphis st1000d...in my old dodge. well, i've got the orion in my truck at .5ohm (roughly 27-2800wrms b4 impedence rise) on a s18x...would u think that's stronger then a mojo running at 2ohms? i have a borrowed st series (i believe.it's silver chrome with the non flamed logo) sitting on my dining table. would it handle .5ohm for burps? a local world champion says the mojo is stronger at 2 ohm then the orion at .5ohm...i know he know…

Hey guys... It's me again... This time wondering if I should pick this one up... Can get the JL Audio 300/2 for about $175.. I would be using it for my front stage... I would also like to get some recommendations for the front stage.... I will be removing the rear deck speakers to make subwoofer sound easier to travel into the cabin... Should I pull the trigger or are there other options out there? I have 4 amps that interest me and are within a reasonable price range... I don't think I want to be that close to the $300 mark... So help me out again guys... I just threw a reference Soundstream in there, although I know its over my apparent budget...lol

i just got word that i might be able to get one of the new jbl amps (bpx1100.1 or bpx2200.1) for cheap.....like manufacturer cost cheap....worth thinking about, i've heard very little about these amps, and if i do decide to go this route it will be replacing my hifonics 1500 to power a xxx15 :boxin:

Ok guys, I'm from the UK, but i'm over with you in the states for the next 8 months or so. Staying out in Melbourne, Florida. I'm after either a decent 3000W rms @1 ohm class a/b amp Or a class D, or pair of class D's with good dampening factors, with about 3kw @1 ohm ultimatly. I have back at home an AA Mayhem 15", which i powered with a Powerbass xa3000D. Which i liked, but i want something to control the woofer better. I've heard US amps merlins and i liked the sound of them . They were running @ 2 ohm though, but i could run one per coil. As i'm not used to prices on things out here, roughly how much money are we talking for a pair of merlins mono's, totalling ~3k? O…

I got the wiring already so would a 2nd run benefit me? I'm running a 240a alt, xs power d3400 up front, big 3 and 2 kitneik hc2400s in the back. Soundqubed 4500. I just hear many different things and not sure if it would be worth my time. Thanks guys

How are they as far as doing rated power and being musical or are they just a ground pounder amp. I am particularly looking at the VLX 1de and 2de. Any help you can give is greatly appreciated.

I was trying to decide on an amp. I was looking at the Lanzar Opti 6000D. Can anybody let me know if they have had an experience or know about it. I will be using it for 8 15's in a ported enclosure from 16-20 cubes tuned at 25 to 28hz. I also plan on using lanzar's line driver.

ok, so i just upgraded my stock head unit to a double din non touch screen thing, JVC something. its alright. i kinda miss my other.... i miss my steering wheel controls, and i hate how my antenna goes up when the thing is on, not just when the radios on. and it sucks that my ipod would be one of the 2 it supports that you cant control from the ipod. only the head unit... but besides all that so, a few problems i might get professionally fixed tomorrow unless its a simple fix. before, i had my suboofer amp hooked up to the back speakers. i splaced into that. i know stupid, i got bitched out on another forum,which is why i have the new deck. so now, ts almost all hooked u…

A few days back I got in my car to head to a friends house. Started the car and as my head unit turned on I heard a sort of pop/thud noise coming from my trunk. It wasn't too loud, but I then noticed my sub wasn't playing. Looked back there and the amp wasn't on. It had worked fine the day before. I checked fuses, grounds, and the remote wire to make sure it was fine. Amp still wouldn't turn on. I opened up the amp and I didn't see any burn marks or any apparent damage, but I took some photos to see if any of you guys happened to know anything... There is one 30A fuse, and the rest are 40A; hoping that had nothing to do with the amp not turning on, its been that wa…

so... i was at BestBuy the other day. just looking. and came across the cda-117. ive always liked the look of the unit and the fact that it has 4v pre-outs... well, i looked at the price and it said $177 clearance. (this means once they are out... they're out) so get it while you can! i was like WHAT!?! so i bought it on an impulse buy. lol. its about #50 from Crutchfield. and lowest i can find is about @285 from an UN-authorized dealer. http://www.crutchfield.com/s_500CDA117/Alpine-CDA-117.html?search=cda-117&skipvs=T SO... if you guys are looking for a nice HU on the cheap, go snatch this up! i was honestly gonna buy the other 2 they had when i got my paycheck and r…

Looking for an amp that is at least 750watts rms for a kicker L7. What brand is better Hifonics or Soundstream? The amps that i am looking at from the 2 company's SOUNDSTREAM PCA2.760 2 CHANNEL 760 WATT AMPLIFIER NEW AND HIFONICS TXi7506 750W MONO AMPLIFIER AMP TITAN TXi 7506

If you had the choice of the 2 headunits what would you choose. This is the first thing im having installed in my car later on i plan on getting a sundown sax 100.4 and running my front stage active. Later on i plan on getting a cadence txa-1000 and an FI BL. Just wondering what headunit you guys like better and why.

Ok so I got a new to me truck. It has a stereo in it already which is good. A JL 12w1v2 in a sealed truck box, hertz components, a rockford punch 300.1, and a kenwood excelon x797 I don't like the x797 so I put my kenwood excelon x998 in it. I can't see the display at all on sunny days with this headunit. I want a new single din with 4v+. I don't care about active, or a CD player. If it has a CD ok no big deal. I love all the features of my x998 but its just no doing it for me anymore. I'm more about features. I will not spend more than $250 so that leaves out the 80prs it seems. I have been looking at alpine. kenwood, pioneer. I think I'm liking the al…

I have an Alpine CDA-9886. The way have mine set is I have the sub out on 15 and the gain on my amp set at a moderate level. I notice a when play it at 20 it'll be hitting good, but when I turn it up past 20, that bass stays at the same level and doesn't get louder. My friend said it's my deck and he has had simular problems with Alpine's and has me interested in a nice Pioneer deck if my deck is the problem. I'd like a 2nd opinion from you guys.

This is the video I took in order to help show what my exact problem is I'm dealing w/ currently....if ANYONE has seen this type of behavior in any Amps OR ESPECIALLY if anyone's had an Orion that acted up like this I'd be very great full for any help or suggestions.. thank you! Much appreciated! YouCut_20181013_000700427.mp4

See the smoked plexi in the middle? What does everyone think? Leave it? Replace it with a clear red? Replace it with clear and have JBL and Crown etched on either side and backlit red?

why was i told that the 4 gauge wire that i am using for my sub is not only overkill but bad for it due to too much resistance? I have not heard of this theory before, is there something that would support this train of thought? thanks chop

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…

HU = Alpine 9885 Amp1 (top) = Soundstream 2 Ch 550 Watt Amplifier TRX 2.550 Amp2 (bottom) = Soundstream 1500 Watt Monoblock Class D Amplifier TRX1500D Speakers (front) = CDT Components 6.5 Speakers (rear) = CDT coaxial 6x9 This is weird, last year I had the same problem but I didn't have the extra battery in the trunk and grounded directly to the sheetmetal. I figured the amp was to blame after some troubleshooting, I RMA'd it. This year I added the battery, using the replacement amp which is the same one and the speakers STILL pop during shutdown. Top amp. Picture of setup. http://b34tbox.googlepages.com/IMG_2964.jpg Here's a video of the problem. The speakers pop when t…
