Amplifiers / Head Units / Processors / Electrical

Hi guys So i recently installed 2 SAZ 2500D v2 in my car with a 2 ohm subwoofer. The master amp went and stayed in protection. Now what I want to know is how do I go protecting any new amp that I might purchase. Runing a D3100, Mechman 270A Thanks

I'm wanting a kenwood or pioneer head unit for my truck (currently all stock), its a 2004 chevy ext. cab. I want bluetooth, am/fm, hd is a bonus, cd player, and other nice creature comforts. I really like the double din units, but I don't like the price, and I'm not opposed to singles. I'm willing to spend up to $350 (not if its a single), but I just don't know what is best option at that price...and yes I know it is personal preference. I would prefer to buy new so their is a warranty, but not totally against refurbished/used. Has anyone used refurbished HU's, what brand, where did you get it, how did it function? Also, can anyone direct me to a good site that does…

anybody have 1 or heard one in person??? just saw a very intersting bench test on youtube....

can i power car amplifiers in home using a lab dc power supply?

Hey guys im not sure how many hyundai santa fe's are out there but im looking at getting wire. Is there a easy place in the fire wall the i can run my wire through? Im going to be doing 4 full runs(2 power & 2 ground front batt to back bank). thanks

got a sa8v2d2 in my 94 grand prix and its running on a friends kicker dx250.1 at 4ohms. so maybe seeing around 150rms. way to little for this little beast. so which one of these 2 amps would be a better deal, or recommend me something. wanting to stay in the price range of thee 2 becauce I plan on upgrading to diff subs in a few months. and im trying to save for a x10 in my 99 grand price. kinda hard when no one wants to buy a lethal injection 12..... reason to go to a 10 is I want to save more trunk space, and I love the lows.

I have a nendo BC2K that got a small amount of water in it,popped 2 transistors/mosfets.I'm having a hard time cross referencing the fets.I dont know if I have the P channel or the N channel fets,digikey pulls all sorts up.part number is IRF 3205.I'm grateful for any help.

Budget is 200 my eye is aimed on the crescendo 600.1 symphony between 600-750 rms is the power im looking for at 1ohm. Other amp was a ppi p1000.1 then my old faithful amp of choice mb quart(One of the series really haven't looked deeply into them.) Any other options I should look at for amps? Only thing im looking for is a efficient amp and the crescendos states 97% at 2ohms gets hot in the trunk in SC my father needs something that can pack a punch for a hour in the temps. Other information amp will be powering sa-8's V1. Electrical is strong for this power draw.

Looking to upgrade my entry-level pioneer DEH-14UB Head Unit IF it will make a worthwhile difference in output or sound level mainly on my sub-stage going with a 4-6v pre-out upper-class pioneer, kenwood or alpine deck. Tell me what do you guys think? I already have the entry-level pioneer wired to a clarion MCD-360 crossover with 5v max output voltage so am I really going to notice a difference in the bass production from the subs or no?? All comments and opinions are appreciated thanks:)

Hello forum folks. I have a 2004 Buick park avenue that I am wanting to install a system into. I have run into one problem...I was about to buy a standard wiring harness when I was told that I would need a "data harness" due to my car having onStar even though I dont use it. If anybody has had any experience in installing a head unit into 2000 and up GM with onstar your assistance would be greatly appreciated. If anybody could link me to the proper harness it would be appreciated as well...as I am trying to avoid paying a shop $700 to install my system. Thanks

I just wanted to give anyone in the market for this HU the info I just found. I just bought this new from onlinecarstereo.com for $279, but if you enter this code, OCSAVE13 it will drop the total down to $262.26. Happy shopping! I can't wait to get mine

Well the last couple days my "check charging system" light has been coming on so I went out today and my car is only charging at around 11 volts.. its driving and staring fine so I dont understand. I haven't had any audio in my car for months now which makes it even more weird. . Right now I have a 220 amp alt and just 2 of my batts in the car. Could this only be the alt messing up? Is there anything I can check before I swap alts?

ordered a 250A alternator Friday the 2nd. just got a email saying its on its way here. Mike Singer not only has killer customer service but the man doesnt mess around.

I just installed a 10" xcon that can either be wired at .5 or 2 ohms. It is currently running on a jl audio jx 1000.1 so 1000w at 2 ohms but I really want to get a 2000w 2ohm amp. Having trouble finding a reliable amp that puts that power out at 2 ohms without breaking the bank!! Not sure if my electrical could handle .5 or id give that a shot.. I drive a mazda tribute stock 110 amp alt and stock battery... Don't really think I can do over 1000 @ 0.5ohm

recently pruchased 3 sets up soundqubed pq mids looking for an amp that can power them much like everyone I am on a budget but i do not wish to sacrifice quality for price . Just having a hard time finding an amp that can fit these prequisites. any help is appreciated

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…

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...

So I have some free time coming up so I figured I would look into running a big 3 just to see if it makes any difference. Few questions... Is welding wire better for the big 3? Does the big three make any difference performance wise? I understand it helps with the dimming of the lights which will be good. If the big 3 works out I am thinking about getting maybe an optima yellow top for under the hood. Slowly trying to build up electrical.

After attending my first bass off in VA last weekend the bug has bitten. Car will be paid off this summer so it's time to start thinking about uprades. I'm not looking to dominate competitions, but I do wanna get way louder. Right now I'm thinking 2-3k would be good for me. Being that I'm running a 5 channel now I know I'll be adding a second amp for the highs. At this point, will an extra battery in back be enough, or do I need to start looking at HO alts? My stock Scion is only 80 amps. Just got a little tax money and would like to put it on something of value towards this. I found a few amps on Craigslist that sparked my attention, although after reading the Stetsom f…

Hi everyone, I have a 1993 lexus gs300. I'm relocating the battery to the trunk, purchasing a 200amp alternator, and doing a big 3 upgrade. I'm running two amplifiers (jl 1000/1 and a 300/4). So I figured at the least I'm going to need zero gauge coming back to the battery. Can someone here please advise me the correct way to run the positive wires? I was planning on running a positive 1/0 from battery to alternator and split it from there to the fuse box and starter. I'm trying to do this right while my engine is outside of the car so I do not encounter any electrical issues down the road.

So I sent in my alternator for repair and the message he sent me was, The rectifier was overheated and the rotor was open (this alternator design is very compact) I have everything broken down for a full rebuild other then the stator now. The stator is in perfect shape still and was never overworked. Just waiting on the parts to install them. So I don't know much on the process it takes to rebuild my alternator sui could someone she some light on this message he sent me.

Ok. I plan on putting 2 15" orion hcca subs in my car and would like to know a few things. I have 2 orion 25001d class amps for each and want to put only 2000 watts into each. So how many amps does my alternator needs to be and do i need more than one? And whats the best type of audio battery to use for under the hood and in the trunk? Thanks.

Does anyone know the diameter of the crankshaft pulley in a 1997 stock 5.7l 1500 chevy suburban? My suburban is in the shop right now getting the fuel pump replaced but i just wanted to know so i could go ahead and order a new alternator from mechman tomorrow. Thanks in advance!

Can it be done folks?
