Amplifiers / Head Units / Processors / Electrical

Im planning on having a 2,000 watt rms amp (hifonics) hooked up in my 95 lexus es300. Im also thinking of a new battery. is optima a better battery than kinetik? or are they two different types of batts? sorry if this is a newbie question...lol.

I am going to Gain match the Amps using a Dmm & an O-scope, anyone done this ? have any input on how to get the most outta the amps without Overdriving them ??? just want to do it different than Strapped any constructive suggestions or input is welcome

I am looking to buy a head unit with a built in gps. I want a high end head unit and I am willing to spend around 500-1000. So any suggestions will be appreciated. It will be for a pontiac g6 gxp.

Hello, I have a '12 mustang with the factory head unit and I want to power the door speakers and a sub. Is there a way to do this without replacing the head unit? My air controls are integrated into the same panel and there are no aftermarket options for me that look nice, and did I mention the faceplates are $300 and up? not including the double din I think a line output converter would be the normal solution but how do you get 3 sigals out of one?

hey guys, i'm here to get some help with deciding whether or not to get a dash kit for an 08 accord for a new HU, but i'm having trouble seeing if the top screen and the steering wheel controls will still be active after putting in a new HU. here's what the inside of the car looks like. And here's the scosche kit Looks like it will fit in nicely, but i'm more concerned about whether or top screen where the radio station, tracks etc. are shown, will stay active or will be all shown through the new HU. Thanks for the help guys.

i have a hifonics bxi1600, and i know no one likes them very much but im hoping you can answer some of my questions. my friend just got a 15" BL daul 2 ohm and after awhile i amp will turn off for about a minute but it is still lit up just very dim. i am runninh 4 gauge wire and i want to know if maybe it is because my amp isnt getting enough power and i should go for 2 gauge wire thanks

i bought this a while ago i did my big 3 with it but the rest of my system is going to be all knu could this be a weak link ? http://www.amazon.com/Monster-1s-125-Powerflex-Magnetic-Quality/dp/B004BXTMOC is this like true 1/0 i cant find anywhere of what load it can handle like on the knu site it tells you how many amps their wire can handle

I've had my KD-ADV6160 for about 2 years now, and havn't had any problems with it, it's a dvd player and in my last truck I did heavy offroading and could hardly skip it, and I mean getting all 4 tires 2 feet in the air and not having it skip when I landed... my buddy and I swear by these decks and I recommend them to anyone wanting a GOOD decent priced dvd player. their cd/mp3 players are equally good imo, my buddy had one in his F150 that he totaled for about a year, and never had a problem with it. when he ran over a ford focus with his truck, it skipped a little but went right back on and both cars were totaled, he went up over it lol. these are a good lasting deck im…

I've been considering getting a new sub amp, mainly looking to switch to class D for the increased efficiency. I'm currently running a Rubicon 702 on my sub and a 100w amp on my highs, and my lights dim at night when driven hard. My final system will consist of about double that much power, so I'm looking to switch my sub amp to something more efficient since I don't want to do any electrical upgrades other than upgrade the battery. I'm looking for something that'll do ~700-800w into 4ohm, 1200w+ into 2ohm, and being 1ohm stable would be nice just to keep my sub options open in the future. Had my eye on a RF T10001bd since I've seen some pretty insanely high efficiency…

I'm wondering why when I changed from 300w @ 4 ohms on my amp, to 600w @ 2 ohms I havn't noticed an increase in current draw. I just picked up a couple Z15s off a seller on here that listed them as DVC4 ohm, and I'm only running one of them due to lack of power/trunk space. I have it wired up to my sae1000d in parallel to get a 2 ohm load. I just pulled a 2 12s out that were wired @ a 4 ohm load on the amp, so I'm going from the 300w @ 4ohm to 600w @ 2ohm. I didn't adjust the gain because the voltage is the same at about 35 volts. But since I'm doubling the amount of wattage being used, shouldnt it be pulling 2 times as much current? The output is about the same as the 2 …

Anyone have this yet? I like the pandora idea wondering hows the sound qaulity of it.

I am getting 15's very soon. Two aq hdc3's off of a 2200d. My electrical now is a 200amp alt, 1/0 big three, and yellow top under the hood. All this is on a diesel engine, that of course runs at lower rpms than a traditional gas engine. I have the smallest pulley I can put on the alternator already installed, and am scared the voltage may not be enough to back this system. Would another battery be needed? If so which one, and for the best price? By the way, this is a daily setup.

So anyway, my brother owns a towing business/ Car parts yard (aka junk yard) ... And he acquires many things. So he acquired one of those industrial sized Optima Yellow tops and a Regular Optima yellow top. I am building my system and a battery was my next step. He gave them both to me, and I was wondering if I should keep them or sell them and put in a large Powermaster or something??? Both are brand new, still in the plastic rappers

ive had my new radio in for a few days and its great. i was going to sushi with my gf and we entered the plaza and as i hit the dip the stereo stopped playing and said protect. i did some research and i saw that there is probably a short somewhere in the speaker wire. im currently on the factory wiring for my front door speakers til i hook up my 2 ch. i have infinity kappas so they have that big external box for the speaker wire so i assumed the skinny factory wiring came loose or something. i saw that some people just reset the radio and it never went into protect again. i tired it and it worked for another hour then it went into protect again. but when it was working i …

What's the benefits of eq's? how do you put it in your system? I'm wanting to learn as much as i can about them....... any advice will be helpful thanks in advance

Hey guys, I have a dxz925 clarion deck and wanted to know about the filter on the deck and my amp. Is it all by ear? I currently have the deck lp filter off and the amp around 60-70hz? Hard to tell with the generic dial on the amp. Is it better to have both on? I have a choice of 50, 80, and 120hz on the deck, and 50hz on up on the amp. I notice the subs sound weird when I turn the amp xo up to much, don't know how to describe the sound, but I'm sure you guys know what I'm talking about. So would you recommend me trying? thanks. btw the gains are about 1/2 way up. sealed box, so ssf is off.

Hello I am an amateur stereo guy in need of advise on setting my amp. I have the gain set to 21 volts on the front and rear of 4 channel with a 1khz test tone I have the gain set to 41 volts on the 1500d amp with a 50hz test tone Those settings were given to me by a friend My question is where to set the crossovers? the low pass/high pass filters the subsonic knob and the 2 push in buttons I currently have the front channel run on the crossover on the head unit set to 100khz with a 24 slope Rear channel is off on deck, and set on low pass on amp but not sure what the settings should be on the amp, the deck does not give me a low pass option on rear channel The sub is cur…

So I have a Sundown Audio SAX-1200d, and I get a lot of dimming. what battery should I get to STOP ALL dimming?? thanks

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…
