I am currently running a set of Crystal 6.5" componants on my Sundown 100.4 The HU Is a Pioneer DEH-P6000UB I keep having some "popping" from the mids.........as if they are almost over excurting at times. HU High Pass is set at 125 Hz The amp is set at Full Range. I cannot seem to find a way to shut off the High Pass on the HU and i wonder if turning on the High Pass on the amp could cause some issues. Also what could be the other causes of this besides it being too low a crossover point? Gain is slightly less than 3/4 no bass boost or anything else. Ideas are VERY welsome. J

Hey, I always wondered if my amp would run at this load so today i loaded it down to see if it would go to proctect mode or get hot. To my surprise it seemed to run it well. What could be some consequences of this that may not be obvious? Clipping? Damaged VC's? Damaged amp or would the fuses blow first? It a one ohm stable D class amp. Thankss

will it be ok or go into protect or blowup? backed by strong electrical of course

i was wondering if DieHard Batteries r any good? The platinum seem to have good specs. and warranties. What do ya know?

I have a chance to buy a used Orion hcca 1000.2 amp for less than 70 bucks and the person said it works. Is this a good deal or sounds shady?

Has anybody checked this amp out yet http://www.audioque.com/aq/AQ3500D.htm I know the 2200 AQ is good and does rated power, should I expect any less from the AQ 3500 ?? Thanks

I have 2 MTX amps that both basically have the same problem. They both have little to no ouput. They are receiving sufficient voltage from the battery (14.4V) and the RCAs (4V). No matter what settings I use nothing changes. Neither seem to have bad transistors or anything. One looks perfect and the other has burnt speaker outputs, which seems to be the obvious problem. Amps: MTX TA81001D (Right) MTX TE1501D (Left) Could anyone possibly tell me whats wrong or direct me to someone that could fix them?

Well I currently have the Hifonics 1606D, but am considering getting something else all ready.

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

Ok once again don't jump on the gimp ass crippled old dude for not understanding a term or wtf-ever you consider this but I recently was seeking an active crossover with the possibility of getting an eq/line driver too since there are such beasts out there in 2018 so I scoured the web's, and the internet's too... I even looked around when I would go into someplace that sells car audio and after weighing my options I did something totally off the wall and bought a Stetsom STX2448 "Digital Audio Processor." I figured: 'Hey I get all of that, plus a parametric EQ and I can configure the xover any whichaway I feel like, PLUS I get to have my first unit that offers time alignm…

Looking for inexpensive Kinetik contenders. Sealed lead acid...

like my title says, i did some trading with a guy and hes sending me his 260amp iraggi alternator. its just over a year old and he has only been using it to power a saz1500 for a few months. is there anything i should be on the lookout for when hooking this up? like is there any electrical upgrades i MUST have done before i can hook it up? i have all 4 gauge wiring now but i am switching to 0 gauge before i try to push anything big. i only have a reg. car battery from napa right now but i plan on getting 2 deka 1800's (from Alan427 when he decides to sell) in the future to run as well. anything else??

I'm starting a new build with tax returns and was wondering what kind of electrical upgrades I'll be needing. Q1-4500 and a Q4-90. Subs will be (2) HDC4 12s (if I can fit a 5cu ft box in my Cavalier and have room for the batteries) or (2) HDC3 10s. Was thinking HO alt obviously, I think 270amp is the biggest I've seen for my car. 2 runs of power and ground, big 3 obviously and 3 batteries in the back. Will that be enough?

Alrighty, so i finally got my front stage installed. But when i first turned everything on each speaker has just about as much, if not more, static than music output. I tried messing with the Xover setting and such, but nothing seemed to change it. Amp: Sundown 100.4 HU: JVC KDs100 Mids: AA carbon fibers Tweets: Seas Prestige 27TFFNC/G (H1396) I've only tinkered with the speakers playing for ~10 minutes, for fear of damaging anything. I'm at a loss of what could make this kind of noise, to every speaker. makes me think it has to do with the amp? All of this stuff is brand new. I did plug in one mid, might have done the other i dont remember, to my factory speaker wire fro…

I was thinking... Deep cycles (ie. Yellow Top) are meant to discharge quite a bit over a long period of time, but starting batteries (ie. Red Top) are meant to discharge large amounts of current over a short period of time, like the starter. Now for our application, car audio, unless playing with the engine off for extended periods of time, wouldn't starting batteries be better? Music is quite dynamic, and as such, starting batteries would be better able to provide the bursts of current. Now I understand that purpose built batteries such as Kinetiks and Powermasters probably have high current in mind, but when using other batteries like Optimas, would a Red Top work bet…

Have an opportunity to purchase a 250A Ohio Gen alt to temporarily bandage my voltage. Has anyone ever used their alts? I heard they put out straight poop @ idle so that is why I am worried. My car idles at a very low RPM: 2004 Pontiac Grand Prix

So last night on my way home from work I was listening to my stereo and all of a sudden the H.U. shuts off and then restarts(Alpine 9884). I installed the H.U. last year in November and never had a problem with it then about a month ago I put in a Sundown SAZ-1000D and a Fi 12" Q. Never had a problem with my H.U. turning off before last night. I dont know if the cold had anything to do with it. It was around 30 out and snowing. Today comming home from school it was listening to it seeing if it would shut off and it never did then comming to work a few hours later it started doing it again. I have yet to do the big 3 and my voltage drops pretty good. Im driving a 97 bla…

Just got the new four channel in! Im confused as to how to set four gains when ill be bridging the amp to run my H.a.t. Clarus's into two channels. The gains are all the way down now so they are all equal. Amp sounds great as is but just a tad lite on gain. The amp btw is a Arc audio ks 125.4 mini.

I was wondering how good his amp would be http://www.sonicelectronix.com/item_13492_...SC+1000.1.html# Ive never really used the MB quart amps, I see it is made by MaxxSonics though

i read a topic with a guy saying he's running an amp at .5ohms for spl and @ 1 for daily. He was running a sundown 3000 amp.Im trying to decide between 2 dual 2ohms or 2 dual 1ohm speakers. I have a hifonics colossus that's 1600 X 2 rms at 1ohm or 3200 rms bridged @ 2ohms. Will my amp run @ .5 for a short spl burst or go into protection mode. or should i just gt the dual 2s? would it be better to run it at 1ohm each channel daily or bridged @ 2ohms? Thank you

So i want to upgrade. But not immediately. like. May not upgrade for a whiiile. But have chance to get a bigger amp. so total hypothetical. I currently have an AQ1200 in my truck with full 4 gauge wires off stock alt and batt. could I, run an 2k amp off of this set up. Never goin over like, probably quarter gain to half. (prollly long time before that amp would clip) 2k amp being a db drive okur 2k. I know anything above 1.5k comes with 1/0 inputs. But could i run it off of the 4 gauge til i can upgrade the rest of the set up is my basic question. Any of your guys' vast knowledge would be great!! thanks in advance!

I have installed a second battery in the trunk and I am going to be running the grounds from amps to the negative on the battery. Whats the longest run of ground you guys have used?

When I installed my alt. it metered out at 14.9 at idle at 260amps. Driving home today I noticed the battery light came on... As soon as I pulled in the driveway I slapped a DMM to everything! Now on all my points I read 26.5 to 27.3 volts....WTF!!!!! I haven't touched a thing since I installed it. What in the hell would make this alt decide it now want to spit out almost twice the voltage? I'm yanking it out for now and putting in the stock alt...(I know it's good) I've had issues with this thing since day one with the annoying whine it puts out of the housing..... Besides the noise it worked excellent...UNTIL NOW!! Any advise would be nice if anyone has any input.. Than…

what can this amp really do with (2) fi bl 18"s? overated or underated?

So, I just but in the new BL, (see sig for more info), and I am very displeased with the amp I'm powering it with, so I think it's time for a new one. Current amp is putting out 600 at 1 ohm, (so it claims, not so sure it is), and I am looking to change that; on a $300ish or less budget I was thinking an audioque 1200d or an SAZ-1000d, (the pre-order for the sundown 1200 will be long over by the time I have the money for a new amp, so it is probably out of my price range). Are there other good choices out there? This is going to be a budget-concious set-up so if there are two solid amps putting out decent power, then I'd go for the cheaper one, unless of course it is o…
