Amplifiers / Head Units / Processors / Electrical

well I think I have desided to keep my factory HU (so I can use the steering wheel controls) any thoughts on either piece? http://mobileaudiocontrol.com/product.asp?...249&l1=5249&l2= http://jlaudio.com/press/CleanSweep05.html I am kinda stumped on what to use----

i was riding in my car on the highway the other day when my subs went completely off and i smelled something burnt. I stopped and the only thing i found was that the wire connecting sub to the amp came out of the amp and i think it touched the amp it self. The amp went into protection when it went off. my Highs gave me a whistling noise when it went off and would get low in volume. After i connected the wire back and shut the car back on. The subs came back on but doesnt sound as loud. And when i turn the volume up, i hear engine noise in my highs. Can somebody please help me figure out what happened and how to fix it. Thank U!

hi, a week ago i decided try to make my Polk MM6501 active. all was going well until i went for a drive around the block and i noticed alternator whine. i am using my alpine 9887 for the processing and my sax100.4 for the amp. and then i have Monster 402 series RCA connecting the two. Now i am having trouble finding out the Cause. i re grounded the head unit to a better spot. I tightened my ground for the amp as tight as i could. i replaced the RCA's with some 8 dollar ones from walmart. and i still have it. and it is only my rear/Highs that have the whine. and i don't really want to have to add a filter because i heard that it affects the quality of the signal…

Does anyone know if the Symbilink cables from Zapco will work in the balanced input of the Hifonics Brutus and Zues amp?

so ive been looking for headunits lately since i sold my audiovox flip out. ive been looking for something with a nice high voltage preout and the best i can find around here is the clarion DXZ785USB with a 6 volt pre out. overall i like the look of the unit jsut wondering what peopel thought of this unit as far as features, sound quality, durability ect go? thanks

Are these amps underrated? Anybody have a birth sheet or a estimate of what the 750.1 will really do @2ohms?

So after asking many questions and buying everything that I need according to people on this forum I have an issue. I have 1 15"bl in my truck with a fosgate 1000bd. Everyone on here has told me I need another cell 0 guage wire, and to do the big 3. Every stereo shop that I went to here says that 0 guage is over doing it. They also say I will be fine with 1 yellowtop and that running 0 guage from the battery is pointless cause the current wire on it is way better than 0 guage is. They say 4 guage is plenty and all I need to do is run the 0 guage from the battery to the amp. Nothing else. They actually said that my 4 guage is fine. So what do I do??? Is it really …

Hello, I have a 2000 Crown Vic Police Interceptor. It has a heavy duty battery and a HO 130 amp alternator. At the moment I have 2 Kenwood 12's (Yes, I know they're not that great, but they get the job done at a cheap price ) with an alpine 500 watt amp. I was happy with this setup until it quit working a couple weeks ago The amp just cut off, and I haven't been able to get it back on (I checked the amp fuses and the in-line fuse). I think the amp is fried, but I'm taking it to get checked out in a couple days. If it is fried, then I'm going to use this as an opportunity to upgrade. I'm thinking about getting an 18" Fi BL sub and possibly an AQ1200D (unless you think I s…

I have a complete budget system that I will be starting as a little project for me. Im a senior in High school with not much money to spend so I'm looking for opinions on a nice budget Amp that will give out about 1-1.5k rms power at 2 ohms (it'll be running to (4) 4 ohm subs). My budget would probably have to be around 150-250$ give or take a little. I'm open to all opinions and come here to ask you guys since no other reviews and forums don't have as much knowledge as you guys . Thanks

Ok. I will give as much info as I can. I have $600 for a new amp. I have 2 FI Q 15s dual 2s in an 8 cube box at 33hz walled. It's a daily setup. Right now I have 2 older hifonics Amps and I'm running them at 4 ohms. So right now I have about a 500 watt system. What amp will be the best bang for my buck thats around 3000 watts? And how much of a difference will a new good amp make compared to the 2 hifonics Amps I have now?

Have you guys ever used or heard anyone using this amp , I got a good deal on one on ebay . but I cant find many reviews, I heard lightning audio is owned by rockford fosgate. its rated at 600 x 1 @ 4Ω 1000 x 1 @ 2Ω 1500 x 1 @ 1Ω and the fuse are 2x70a here is some internal pics (not mine)

It's been a while since I've used my o-scope and I've read alot on how to set the amp gains but while i've been trying to see the clipping I've had some problems being able see where clipping begins on the h/u. From what i seen it was at 53 on an alpine deh-4000ub as i was setting the gain i barely touched the gain knob and it was in clipping and i dont want to have my h/u at 53 just to get bass. im using a bk precision 2120. i'm running a re -sx 12 in a 35hz box connected to an AQ1200d. can i get some suggestions on the way to set these properly fellas?

Should i use a Kinetik 600 Power Cell in my install for my front stage? -- Will it help with my voltage? OR! Will it strain my Alt? I know its only 400wrms.. but i have the Power Cell already. (2) Alpine Type R 6.5 component sets (1) Alpine PDX 4.100 KnuKoncpetz 4 gauge amp kit Yellow top as starter batt. 1/3 Big 3 done. (Batt to frame) Stock Alt -- 80-100 amp (not too sure)

i am looking to get 1 icon 12 but i am not sure where to start looking for an amp. Any suggestions?

So far in my 2001 Ford Windstar I have: 2 Alpine Type Rs Hifonics Brutus 1200 mono at 1 ohm Kinetik HC1800 under the hood Big three upgrade 0/1 gauge wire I just had a new 250 amp alternator installed. After hooking up the radio my lights STILL dim and looks as though the amp is dipping. Why am I still having this problem? I thought I had gone through all necessary steps but I guess I'm missing something? What is next a second battery? Any help or input greatly appreciated. -CHRIS

I current have a 250a DB Electrical alt installed with a Deka 9a78DT as my front battery running 1500 watts. At idle I drop to around 13.9 and when cruising I stay right at 14.5 volts. Now I want to run 4300 in the near future and need to know how many batteries and what batteries would be best. I'm kinda thinking three Deka 9a31's but am open to other things and am willing to buy used. I want to try and stay around 600 for all of them so gimme an idea for how many and what I should get.

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…

When you run active does that mean the driver of the car gets the best sound? Not the passengers?

Video explains all, running on .7 ohms drop from 13.6 to 12.3 is what i was seeing http://www.youtube.com/watch?v=e-k1pUb3HzA

Ok I hope I set this up correctly. Got another question for everyone. Decided to make it a poll. Years ago in the area I grew up in everyone used bass blockers to remove lower frequencies from the smaller speakers 4x6, 5x7, 6.5 and 6x9's. Keeping all the lower bass to the larger speakers. The smaller the speaker the higher the bass blocker frequency. The larger the speaker the lower the blocker frequency. Till you got to the subs. Then they were controlled by the amp so none were used. I have never used them myself. But I am now finding myself looking into purchacing some for my non amped, non component speakers ( the ones listed in the poll ). What are your op…

I have two FI Q 15 inch subs that are each a dual 1 ohm coil. I had them running on two Rockford T10001bd amps and then switched to a Sundown Audio SAZ-3500D amp. It seems now that for some reason I may have lost some sound quality when going from the rockford amp to the sundown amp. It just seems like the subs may not be hitting all notes or sounding as good as before which is when I ran them on rockford amps. Does anyone know if this is possible or even who makes a better amp whether if its Rockford or Sundown Audio? These subs are fully loaded with each being in its own 2.5 cubit foot sealed box. I guess I am just looking for the best amp here which could match th…

Ive already got a yellow top and a kinetik 2400. wondering what kinetik would compare to either a yellow top or red top

I would like to know about all the different RCA cables like 2 channel, 4 channel, and 6 channel What goes best with a Sundown Audio Monoblock Amp and one sub? I plan on buying a 2 gauge Tsunami Wiring kit and it only has the power, ground, and remote so I have to buy a RCA seperate and I want to make sure I don't buy the wrong one. Thanks!

Hey guys, The system in my 2011 Ram is driving me crazy... Here is what is going on. At high volumes the draw from the amplifiers is kicking my trucks ass. The dash lights are dimming, the voltage drop is causing my HID lights to kick on and off, and I'm pretty sure that the PCM is trying to compensate by increasing the voltage regulation from the alternator. The voltage regulator is controlled by the PCM. It is not built into the alternator. When it is playing loud, it seems like the PCM is kicking the voltage up to about 15.5v according the my Bel radar detector voltage display and the HI VOLT warning it keeps flashing and beeping at me. The truck has a 180amp alternato…
