Amplifiers / Head Units / Processors / Electrical

I have a pioneer avh 165dvd head unit which shows amp error. I'm not using speaker connection from head unit.

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…

Ok so with a sundown saz1200d its 12 volt ratting is 1200+ watts an something like 1400+ at 14 volt .. so when setting the gain to be some where safe would it be better to set it with the car running? I have the big 3 done an a hc1400 up front an a hc800 in the back...

If you do not know what these are, i'll explain it then go into great detail about the design application and see if it's what you want... Fluxcaps are not fake, this isn't a movie joke, it is an actual device name given to a special capacitor that does many things- It is a Battery isolator, Voltage Booster!, and capacitor all in one. Standard versions put out a constant 14.7v(some restrictions may apply...) but this topic isn't for 14.7v... this topic is for 18v electrical system. This device can be used on a stock or aftermarket 12v electrical system to bump up the voltage all the way to be able to charge or run an 18v electrical system to get the most power out of your…

You guys are gonna hate me for the next couple hrs but i want to go ahead and make this thread while i get all the info ready and post it at once... Unlike other competitors, i like to share what products are out there and where to get them for what price so we can all have some fun I've been talkin on another forum about this one particular battery brand and is sparking some big interest in the car audio world so after talking with the company over the phone about specific questions.. i think it's time to share some information! So.. give me a couple hrs or less, hopefully a LOT less time and i'll have this thread the new hot topic for a while... Direct link- http://ww…

Just thought I'd make a little thread for my new arrival! By the way, does anyone know when these guys were produced? There she is! Picked her up for around $57.00 including shipping off ebay. The seller claimed that it was in working shape and claimed that he/she had tested it before shipping out. After opening it up i'm a little skeptical, but then again I dont know a whole lot about boards. it just doesn't look as the brand new boards that im familiar with (go figure right?). Hopefully i can test it this weekend, but time is tight in my schedule. I plan on using it to power my alpine type r's i got from Swagger_Wagon! Time for more pics! Some are displaying some spots…

I'm in the market for a new amp and will be running it @ 2ohms on X2 SA-12s is either one of these any bit significantly better than the other (SQ, Doing rated etc)

Dave Navone says that you should use a -10dB tone to set your amps gains for a 3:1 ratio overlap. Should I do that? I've been using the 0dB tones. Switch?

so I knew it was happening, and was in process of saving up for a custom valeo Ohio Generator alternator. current alty decided to crap on my today, so I need to order a new one this weekend. I don't have the 450 to dish out for the Ohio right now, and saw what seems to be a reputable company selling a 200 amp for 210 plus shipping on ebay. BNR alternators and starters? I would rather spend the money on a 160 amp higher quality alty than a 200 amp piece of junk. My experience in past with alternators is iraggi, ohio, green monster, and that's about it. Any input would be greatly appreciated thanks! right now battery bank consists of a single hc1400 and hc2000, and p…

I was reading some of the threads here and I noticed a lot of you really don't like Hifonics. I just bought the BXI1206D and ZXI6406. I know exactly why most of you hate them, looking at your set ups (very expensive) i can totally understand why. Noticed a lot of Sundown Audio fans here. All i have to say is that they are beautiful amps, I would love to have one but with 2 kids and the budget i'm on i just couldn't afford it yet. I do hope my Hifonics can serve me well for the time being until i can afford better stuff. Just wondering, what do you all think of Elemental Designs amps (nine.1, nine.4 and nine.5)?

www.usamps.com for more info and dealer location Hey all, I got back from the USAMPS factory today and met the owner, Mr. Daniel Kim (my uncle), the Sales director, Mr. Jeff Coleman (some of you probably know of him), and the head engineer (CO-started USAMPS and designs all of the boards.) Mr. Dirk Ecker. But umm okay first off I wanted to say that these amps are AMAZING. I ain

As the title states, I've got one of these HU's coming. It's BNIB, never used, never opened. It wasn't really a planned purchase, the seller posted it up on EBAY and when I threw in my max bid it was at $32. After a few other bids went on it It came to $104.50 and that's what I won it at! Pretty damn decent deal IMHO. That brings me to the point of my thread. Anyone have any experience with the EQ settings on this unit? It has a plethora of crossover, DTA, and EQ settings, but it's only a 5 band parametric EQ. The question I'm trying to answer is, what frequencies can you select for each of the bands? The book only says 20hz - 20khz. Most list the frequencies suc…

Is the 800prs just a newer model and black? Are there any real differences?

This wouldnt be really recommended for those who do not compete so I'll tell you now that this isn't necessary or needed for normal use of an amplifier. But for those who want the most out of their amps on the meter, read on... I am going to be getting into some projects soon for the car audio comp world and start making my own everything... I have several plans laid out for the competition world and for starters, i plan on making some multi insert wire blocks. Basically what it is is this- (for amps that accept 1/0 inserts only at this time) It would be a block of copper that inserts into the amp's power\ground terminal then outputs in a manner that can accept 2 ring ter…

I have an AudioQue 1200 running my single fully loaded 10" FI Q. Wednesday omw to school, my amp cut out. I took the inline fuse out (which looked perfectly fine) and replaced it (i use 100A fuses). Thankfully my amp started working again. Thursday omw to school same thing happened. my amp cut out. This fuse was definitely blown. I immediatly ordered a circuit breaker because I was tired of replacing the fuses (the audio shop where i got the stuff installed at charges me $5 for a fuse). I went to Advanced Auto Parts store and bought a 50A fuse hoping it will hold me untill i get my circuit breaker. When i put the fuse in the fuse holder, the power light on the bass…

I talked with my uncles (the owner of USamps) wifey last night, the operation is a husband and wife thing, and I found out my uncle REALLY DOES own USAMPS, 100% sure of it. And the cool thing is, the guy wants to meet me! I told him that i had some ideas about how to get his company's name out into the public, and he wants to talk to me about them! I am soo happy!!! I

About 2 years ago I removed a system that was "blown" for a guy and put his headunit in his new car--loose wires the only problem. For payment he gave me his blown amp and two kicker subs. I sold the subs cheap to a buddy and kept the amp. Since my car is mostly done I thought I would put something in the truck. I was wondering if any of you had heard anything about the amp. All I found is a random post saying it is 40x4 + 80wx1 or 80wx3 (@4ohm). I would like to use it to power my fronts and my sub. I have not selected a sub to use yet. The appealing part of it is that it looks like it is truly class A. I didn't notice this until today when I started to look onlin…

Here's a few pics of my MB QUART ONX1.1000D amp. I got it at sonic electronix for 150 shipped. It puts out 1000 watts rms at 1 ohm. I put in a pic of the amp guts since there aren't many of this amp online

aight so i will be getting two 12 DSS Ethos in oct.. they are 1,800 watts RMS.. there is two so could i get a 3,000 watt amp for them or will i need to get a 3,500 watt amp?? also i only have about 650$ to spend on a amp which sucks.. any thoughts on what i should do? i kno i will be needing to get a second battery and a better battery for under the hood.. i never really had much of a system.. i only have two 10's now and a Hifonics BE1700.1 for the 10's and a alpine 4 channel for my door spearkers.. this will be my first time upgrading my electrical.. will i need to get a better alternator or can i just rock the 2 better batterys.. my new build will be the two 12 Ethos.…

this is what i want to do. if someone could draw up a nice detailed wiring diagram to help me better understand it, id really appreciate it ok first off, please dont hate, you guys know how i do with the mids/highs, im just looking for someone to help, if you dont want to help me, please dont post and get my thread locked or start arguments. ok, so, in the mini cooper, ill have a total of 3 amps. they're on order so theyll be here soon i have the 18" mt, 16 6.5s in the front cabin, and 16 tweets in the front cabin. in the back (behind the wall in the cargo area) i will have 2 sets of components (or 4 coax, whatever i decide on) for shows or whatever. the front 16 mids w…

So i am still confused on head units.... So I called the local shop where i want to get my car audio equipment installed at, due to their reviews and prices for installation. But the dude on the phone just told me some concerning things... makes me rethink even going there to get the installation done. Or maybe he is right? He says he has been doing this stuff for many years. I told the guy i wanted to get 2 front component speakers installed, a new head unit, and an amplifier for the speakers. The amp will be 4 channels, to allow for upgrade of 2 more rear coaxial speakers later. And the head unit will be one with 3 outputs, front, rear, and subwoofer. The guy …

I was going to by the RF 3sixty.3 today, then noticed a JL clean sweep. From what I can gather the JL simply converts the signal, from a OEM head unit, to a flat signal then outputs to an amplifier. The RF360.3 will convert the signal, from a OEM head unit, to a user defined signal via the EQ functionality then outputs to an amplifier. If I purchase a RF360.3 how likely am I to give my amp, SAX100.4, a flat response? If I purchase a JL clean how likely am I to make that signal something other then flat? In other words for me, a person who doesn't compete but enjoys good quality, would I be better off with a JL or an RF? Also from what I have read, if I change the EQ…

Im trying to put together a new system for my car. Im aiming for about 7k watts what electrical needed for that? i already have a high output alt,i bought it from mechman last year so i cant remember if its a 260 or 270 amp

I know that the older amps they made were amazing but I was wondering if any has tried their new amps and if they are high quality or not. Input would be much appreciated since I looking to purchase a new amp. Thanks in advance Sincerely, Matthew

ok so i need a good 4channel for my cdt-ef61fg comps and my pioneer 6x9s in the back so i need a decent amount of power.i was looking at the pg xenon 200.4 or maybe the jbl gto 75.4 but im not sure,do you guys have any other suggestions about some good amps for under $250???? right now i have a crappy alpine mrp-240...(40x4) and the comps kinda sound flat so i need something to bump them up to par....
