Hey guys what up? I have recently start having problems with my HU that I cant figure out. Ive had it now for about 2 years and I notice last that am getting this static, popping noise when I turn my sterring wheel or turn the sub level up. I also tapped on the HU to see if I would get any noise and I did. It seems as though anytime the HU get a bit of a jolt it starts with the noise, whether its me just tapping on it, turning the steering wheel, or turing up the bass level in the truck. Any suggestions? If am leaving anything out just let me know and ill fill it in. Thanks

So I got one of these off ebay and unlike the stinger one it only has 2 wires. And if I was to hook it up straight to power it would be on all the time. Was thinking of either running it off the ignition wire that triggers the head unit to turn on or running it off a switch so I could turn it off. Or do you guys think another way would be better.

So I got my JL 500/1 for my sub setup Friday, didn't have time to install it til today... One issue... The amp doesn't seem to kick in until I hit about 50% of max on my Pioneer HU.. I know it is not the HU because it was beatin' in the morning with my old setup (Kenwood).. Two things happened when doing the "swap" of amplifiers... 1. Apparently one of the ring terminals on the wiring was shitty, and came out... 2. I replaced the terminal with a new one I bought at BestBuy just so I could get it done... When installing this onto the capacitor that was already in my car I accidentally touched the wire to both ends... Spark and sizzle but everything seemed ok... Now again..…

Which is a legit website to buy a BNIB Alpine 9887, not refurbished. OCS: Alpine CDA-9887 In-Dash Receivers with Bluetooth - Video/Multimedia at Onlinecarstereo.com -says brand new sealed in factory box -seems as though reviews of this site goes both ways. PowersellerNYC: PowersellerNYC - Alpine CDA-9887 CDA-9887 CD/MP3/WMA/AAC Receiver -says refurbished and for the same money OCS is advertising its making me think OCS's may be refurbished as well. -not sure on the sites credibility DCCA: Alpine CDA-9887 CD/MP3/WMA/AAC Receiver - iPhone Compatible -says BNIB factory sealed -reviews on this site go both ways as well ASW: Alpine CDA-9887 CD, MP3, WMA PLAYER -doesn't say…

Just got a Fluke 87 ture rms multimeter My link I don't know if it is accurate or what but i read the owners manual and am mind boggled. how do I tell the voltage readout on this thing? It says ac voltage=2.5 but i know thats not right. any ideas?? Thanks Matt Cusack

Hi Guys, A friend of mine needs to finish the big3 in his car. He's wondering how to put the wire between alt to batt. From stock, there is a wire coming from the + of the alternator, going to the starter(démareur in French !) And this same wire goes to the + batt after the starter. So, the question is : can we just put a wire between the alt and the batt without hooking it to the starter ? Or do we have to follow the stock wiring ? Waiting for you, all the experts, please!!!

Ok so here's the deal, I have my 18" SSD and I'm about to get a bigger amp for it (aq1200d or audiopipe or sax1200d) back to the point.. I want to make sure I have enough power to give it. I drive a 97 civic I think its like a 70amp alt. All stock electrical ( im also doing the big 3 to all 1/0 next week ) but I dont know enough and need help about batteries. Basically if I add a Battery is that going to be enough power to run my subs or do second battery's not even help on a stock alt? I see a bunch of people on here who always have batteries added and so I want to know if i can just add a battery to the back and be ok with my stock alt. I'm think along the lines of a…

So I just upgraded from a factory HU that I had connected to my Sundown 2000D with a LOC. With my factory HU, all I had to do was bring the volume to 12 (75%) and then get my bass knob and increase it 4 clicks. That was loud bass and loud mids/highs with no distortion. Today I just got a Pioneer DEH-P800PRS. Installed it, took out the LOC and connected the Rockford RCA cable to the Subwoofer output. Reseted the headunit to default (by pressing the small button on the front of face plate), started listening to FM, CDs and even my iPod and realized there is no bass. I checked the LPF and its on default 80hz. I havent touched any filter on my amp. I even thought I had to inc…

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

My new amp (Aq1200d) came in. Verryyy nice. Not a whole lot to say about it yet besides that it seems to push alot more than my old bxi and seems pretty reliable. Looks fantastic. Thumbs up to the guys at Audioque excuse my dirty carpet, it will be cleaned soon.

Okay guys.... Your assistance is needed once again... I had my equipment installed by a buddy and since I had planned at the time to run my Kenwood amp at 1 ohm with a 15" Kicker L7 my buddy dropped in a RF 1 farad capacitor while we hooked this all up... I already know this negatives here and so I would like to remove this while I do my amplifier swap hopefullly this weekend.... Here is the big $100k question: How do I discharge the capacitor? I will disconnect the power from the battery and then remove the capacitor fully as I understand it... But I don't want this light bomb sitting in my apartment with energy being stored... only found this link .... Should I ju…

So my friend just got a new Sundown amp. The recommended fuse size is 200 amp. He just told me on the phone he currently has a 60amp fuse on his fuse holder. He asked me if it was fine to use what he had, I said I was going to ask around first to see if it was ok to do so. Is it ok to use a 60 amp fuse or will there be any problem/risk or anything?

System consists of the following: • 2010 and up Camaro drivers side large stealth enclosure from Subthump • Knukonceptz 4AWG wiring and interconnects and speaker wire • MTX RE-Q • Subthump T-Harness (used so that we DO NOT splice into the factory wiring) • 12" Fi Q (dual 2 ohm wired to 4 ohms w/ all options and high qts) • ZED Audio Kronos bridged @ 4 ohm (1000rms) There are a couple things that seem to be off. For one, we are using the factory headunit and thought that the RE-Q would be perfect because of the bass restoration, and the fact that the Kronos needs unbalanced grounded preouts (as said by Steve from ZED). Now, due to the fact we havent installed any bass blo…

I am looking to rebuild/convert my CS130 alternator to a high amperage unit. This is for the car and system listed in my sig. What are the limits this case can handle. I came across a 200 amp stator. The biggest rotor I've come across is 140 amp. Will these work together. To go along with this I was thinking about using a heavy duty Delco voltage regulator set at 14.7v, and a Delco rectifier with six 70 amp avalanche diodes. Any thoughts of what the output of this combo would be? Should I get a smaller pulley as well? Thanks.

Does anyone that is familiar with the Audiopipe 3000D (The one that is two 1500's strapped) familiar with what kind of current it pulls? I plan on getting one in the future, and I am trying to plan out my electrical system. I need to know what it takes to be able to back one of these suckers up. I currently have a 220amp h.o alternator, 1/0 Big 3, an Optima yellow top under the hood, and a run of 200amp fused 1/0 cable to the back.

What is this thing worth in good shape used? Guy locally offered to trade me my Soundstream XXX4000d for one. Im just gonna turn around and sell it if its worth much.

So if you put the power, ignition and ground from the head-unit on the battery directly and there is no power, is the head-unit faulty? Because i only get a tiny tiny spark on the positive post... other then that, no reaction. http://www.alpine-usa.com/product/view/ida-x305s/

hello i have two JBL GT4-12 sub woofers which mono amp would be best to power them up. Subwoofer Specifications Subwoofer Size 12" Voice Coil(s) Single Impedance (per voice coil) 4 ohms Peak Power Handling 1000 watts RMS Power Handling 250 watts Woofer Composition Polypropylene Woofer Surround Rubber Sensitivity 93 dB Frequency Response 23 - 450 Hz Xmax (millimeters) N/A Top Mount Depth 6.25" Cutout Diameter 11.14" my budget is 300$ please kindly reply regards simmer

Please someone correct me if i am wrong, i am going to strap my Sundown Audio 3500Ds and this will be my first time strapping amps, so i need to see if i am thinking correctly. The Master amp gets the input from the head-unit and a mono RCA from "BR Out" connected. The Slave amp ONLY gets "BR In" connected from the Master amp, leave the Gain and other Filters on the Slave amp set to 0. Each amp gets its own remote wire coming from the head-unit. Each amp gets its own Power and Ground. Connect NEG terminals of both amps together using 8AWG wires Wire my subs like so; Then take the POS wire from my sub and put it in the Master amps (far left) positive terminal, then take t…

Looking for some help with what to put my settings at, I understand most of them, but not all of them. Was hoping you could give your educated opinions on what to set my equipment to. The equipment I am working with is a JL 250/1 (powering two American Bass 12's), an American Pro VS1407 (powering two pairs of Planet Audio 6.5's) and a Blitz 2-way crossover (has a remote bass knob with sub gain and frequency sweep). These are all the settings available to mess with. JL 250/1 Full/Low/High LP Filter Mode/Slope - Off/12dB/24dB - 40Hz - 200Hz Bass Control Infrasonic Filter - Off/30Hz - 0dB - +15dB Amp Input Input Voltage - Low/High Signal Sensing …

I was thinking about purchasing a SAE-1200dv2 from dB-r and I noticed that the refurbs they are selling don't come with a bass remote. If I were to buy one where could I get a remote? Straight from Sundown/Jacob? Thanks

Hey all.The UPS guy just dropped of my new aq2200 amp.Can't wait to get it hooked up!!!

I have a power acoustik vu560-4x. Back in high school was being dumb when hooking it up and crossed a wire or two and basically it went up in smoke. Basically determined the problem to be 3 of these mosfets. Just wondering how hard it would be to replace these. Would it be just some simple soldering? I figure the 5 bucks it would cost would be worth the try for a highs amp.

I am looking to install a Sundown SAX1200D in my truck after I get the money up. My question is to run it at 1 ohm what all will I need to upgrade on my electrical besides the Big 3? If I need a larger or more batteries what size should I run and what should I run for the alternator?

Waiting for Maxxsonics to return my call with regards to this so while i wait, let's see if any of you know this- OK, we all know the Maxxlink is a processor that can take up to 10 amps and strap them externally as 5 set pairs. This is where i want to make sure i can do this... Instead of strapping mono channel amps together, can u strap amps that have been internally strapped? IE - one board is sold as a 1500w amp @1ohm and another amp has 2 of these boards in it rated at 3000w @2ohm.. Would you know if u set these amps up in bridge mode to form a mono channel if one can safely use a maxxlink and strap a pair of amps like this to 6,000w@4ohm? Also, from what i gather.. i…
