Amplifiers / Head Units / Processors / Electrical

Currently have 1 run each 1/0 gauge wire on a 180 amp alt with 3 kinetik batteries on the back (running 1 audioque 3500d.1 in the back). My voltage at ilde is dropping to around 12 volts and at 2000 rpm it is dropping to around 12.3 to 12.5 volts when i'm cranking it up for demos. My question is would adding another run or two of 1/0 help keep my voltage up or do i need a bigger alt?

If an amplifier is receiving a bandpassed input from the head unit of say 60hz - 2000hz and I used the RCA out from the amp to another amp will the second amp receive the same frequencies as the first? I would think so as I dont see how it could be full range as it's not receiving full range input from the source. Just thinking and wanted to double check with some of you guys to confirm. ?

Does anyone have a 2000-2004 Impala with this HU (AVH-3200DVD) in it....If so could u post pics I would like to see how this would look in my Impala before I bought i....Thx!!!

So I dont know if I will need an alternator, at least I hope not. However, if I did I dont think it is possible to find an aftermarket one for the 4.2L as it is not a very common engine in the f150...anyone have any ideas (I would not be able to afford an alternator for a long time anyways, might have a new truck by then anyways...)

I have and Audiopipe APSM-1300 that went into protect mode while riding down the road. I had it wired to a 1ohm which is 1000 watts. The amp is grounded beneath the drivers seat at a spot were I sanded the paint away and secured the ring terminal with three screws to the floor. I have an 8 gauge kit with an 80 amp fuse. My question is it possible the amp was struggling too hard with the small wire to generate the power or the amp hit the drivers seat frame and maybe shorted out. The amp is damaged now and Audiopipe wants $20 to fix it and whatever it cost to ship it. I only paid $100 for the amp and I think I will go with something else instead of fixing it. Any thou…

I've been trying to trouble shoot my hissing noise for a while now and don't know where else to look. When the sub amp is hooked up, the subs have a slight crackle, and the tweeters hiss. But when I unhook the remote to the sub amp the highs are fine. I've moved all of the grounds in the back around to a few different places. I've also tried grounding the head unit, and checked the rcas and tried a different set of rcas.Also added a relay. Grounding the hu kinda lessened the hissing in the highs, but not too much. I don't really know where else to check. I was thinking about just getting a new hu to see if mine is taking a shit...Any advice?

I have a feeling this is a pretty common problem that some of you have dealt with. So hopefully you can help me. I have a Fi BL 12 running off a sundown sae1200d. And when I play it at full tilt at idle, I get voltage drop into the 13.0 range (and sometimes even a bit less D:) Although when driving or holding the revs at about 2k, the voltage has no problem sitting at 14. I'm pretty sure this is an alternator issue. But ive heard that even HO alternator have poor output at idle. So what do I do? FYI- big three is done. And all wiring is in 1/0 Also, I currently have a quote from Excessive Amperage for a 200 amp alt for $385. Thanks in advance.

I have 2 Kinetik HC 2000's in my tahoe which is broken down for the time being. Fuel pump took a dump and its in-tank. not to mention i was just layed off from work.. its going to be sitting for a little while. Do i have anything to worry about, will the battery's be fine? ... im only asking this because im pretty sure ive read about this somewhere else but have nothing solid to go on.. i mean if they go dead i charge em.. right? lol. Just unsure and could use some clarification.

Ok so almost 6 months ago I loaned my car to a friend and when I got it back my subwoofer was not playing. I started a thread on here asking about how to fix it and what not and I never really came to a conclusive answer. I just got a Sundown SAZ-1000D and plugged it in and went to check the output voltage of the amp and even at high volume with the gain pretty high the highest I get is 3.x AC volts. I am getting power to the amp and it turns on without the protect light or anything I checked the DC voltage at the amp, its in order. Now the one place that does not seem to be right are the RCAs. No matter what I do I can't get them to register ANY voltage no matter how lou…

Could someone recommend a good amp for two SSA ICON 12's....please?

I was looking at a aq2200d. I have a 2009 Tahoe with a 4.8L?. So I was thinking if I had a upgraded battery in the front and a bank of kinetic 1800s or similar from XS power(which one would be better) also open to other suggestions? Would that be enough to run a aq2200d at .5 daily? It will only be played at full tilt for demos. Also I will probably put a battery charger on the bank at night.

So I bought my Head Unit, Pioneer DEH-P4200ub. Bought all the installation gear I needed. I connected the wires correctly and when I plug everything in the unit turns on but the speakers aren't working. With the factory radio they work fine. I called best buy and the dude said that because I have onstar I need a special harness that's 100 bucks, and if I don't use it that the door chime won't work and the check engine light will come on. So my question is do I really need this special harness to make the speakers work as well? Is there any way I can bypass this? Or am I just not hooking it up right?

thinking of buying one...anyone have an opinion of these batts

Hi sorry if this Is In the wrong area.Ok, I bought a c90 on ebay,it suppose to work, BUT when i got it does not face wont go all the way down to allow a cd to be inserted, And the seems to be a cd jamed In It.The dang thing looks new even the cooper body is almost flawless.My question is can It be fixed? and are parts even avil. It came with org. box both remotes and instruction manuel. It Is a very nice piece. thanks.

a lot of people i have talked to on forums say to stay away from optima yellow tops, why?

im running 2 saz 4500's to 2 fi btl's and i was wondering should i strap them or dont? what is the purpose of strapping?

I'm looking at getting this head unit. Anyone with experience with it? I have owned a eXcelon X889. Loved it. Wish I never sold it. Would this be a nice choice or is there better for around the price of this one?

Right now I have an saz-2500d and I am getting the electrical to power it sufficeintly. As for batteries, the one I have now is a perfectly fine battery, I do not know what kind of amperage its putting out but it is a stock carquest battery and rests at 12.5. Car on, I rest at 14.0-.1. I plan on doing... Excessive Amperage 200 amp Alternator Big 3 And a bettery for the rear (Possibly Deka intimidator 9A31) My question is on batteries... I don't want to spend a load of money on batteries so I'm wondering if a stock battery and 1 rear would be okay. Another thing is.. If my stock battery rests differently then my extra battery would that be okay, or what part would I need t…

Ok, I have never owned an amp w/o on-board fuses. I understand that fuses are necessary, but I am a bit confused about just how they are installed and WHY they are necessary. I'll probably purchase an amp kit that comes with an in-line fuse. I understand that this is to protect the battery in the event of...hell idk, I just know it's to keep shit from catching on fire. Now further down the line, the two amps I have have on-board fuses to protect themselves in the event that they should draw more current than they need/can handle. (Not quite sure about that either. I know that fuses usually pop when too much juice passes through them.) Now...I've been avoiding this by limi…

first off im a 16 year old kid with little experience. ive done a few installs before but not very many. i have a single bl 15 on a sundown sae-1200d. but anyways my friend has a 1998 dodoge dakota and i was attempting to put a brand new kenwood head unit in it. and when i was wiring the after market harness to the head unit harness there were some weird wires. theres two harnesses to wire, one has 3 of 4 speakers and the remote wire on it and the other has power, ignition, illumination, dimmer, right front negative, amplifier ground, and mute. there is no wire from after market harness for left front negative but the one that says amp ground is the same color (white and…

The new SAX 200.4 makes me feel like everything I ever bought has been wasted money! I hope this isnt going to be considered spam. But I just had to SCREAM IT AT THE TOP OF MY LUNGS! Come to me SAX 200.4 . Unbelieveable. Just had to tell someone.

My sister just got an 04 Land Rover Freelander and I'm wondering what size head unit fits into this car. The stock radio is a cd changer that takes up far more room than a single din head unit would but I'm not exactly sure on what size would fit. Any body Know what would fit?

Well I was planning on getting the Sundown 2500 until it went to 815 dollars, there is no way I have the money for that, I can dish out maybe 600 tops...was looking at the HiFonics Brutus 2400, but I dont know if they are good or not, everywhere I have looked they have positive feedback...any suggestions??

Looking at the audiopipe AQX-3500.1 they are priced great for the power just want to get some feedback on this amp any info experience would be great thanks.
