Just wondering if anybody knows anything about the Rockford Fosgate RF-BLD. it says install it as close to the source unit as possible, why is that? Why can't it go in the trunk by the amp?

My brother just bought a ssa xcon 18 an a audioque 2200 watt amp, can anybody suggest a second battery cheap in price but will do the job? The car is a 2009 dodge charger and the stock alt is 160 amp..Thanks for any help.

could someone give me a list of amps that do 2500 watts at 2ohms.

I have a memphis 16-2000d amp and it has no fuses. If i use a 300 amp inline fuse in the power wire and hook that straight up to the amp will that be ok?

Ok, so I just received and hooked up my saz3000d and everything went smooth. It is a very powerful amp. However, I am having one issue. While the truck is NOT running and my head unit is paused, or the av source is off (it is a avic-n4 nav) so the hu itself is still on, and so is the amp. There is a low humming sound coming from my subs. Something else I notice is when I touch the amp it either goes completely away or almost does. Can anyone shed any light on this for me please. More info you may want: I have quality rca jacks no where close to any other wires. I relocated my ground with no change. I have a memphis eq.

Here's the deal - I'm working on putting my system together. I want to make sure I have my electrical taken care of. Amp will be 3000rms I was thinking about the following options: Option 1: Big 3 HO Alternator - 165amp Idle / 260amp higher rpm ---------- Option 2: Big 3 Stock Alt - new, but stock. XS Power D3100 Battery --------- Option 3: Big 3 Stock Alt 2 HC1800 Batts ------------------------------------------------------ Amp would probably be GP3000D running to 2 15" MTX 9500s. Or could I do a HO Alt - which is going to be $500 for the one i'm looking at, and maybe an optima yellow up front? Any help appreciated.

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 …

I wanted to pick up a eq soon to really fine tune my system i was thinking of like a 5 or 7 band with sub level, anyone know of any good 1/2 din eq's?

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.

I want to make sure my amp is set correct so I am going to try and pick up a digital multimeter soon. I have never used before though. Do I need an expensive one or any work fine. (http://www.sears.com/shc/s/p_10153_12605_03482141000P?prdNo=2&blockNo=2&blockType=G2). Using the equation in the topic my voltage should be about 22.3v. What would I set the dmm in the picture too?

a friend of mine keeps going on about this company so I looked into it and found a D3500.1 for a reasonable price but the guts didn't look too smashing are they really that good?

My first official post of audio haha . Just had a quick little question, I have a 18" Fi BL and i want a good amp for it. So i am deciding to get a 1200 AudioQue amp or a Rockford Fosgate 1500-1bd. Any idea which amp I should get. Thanks guys !

I'm planning on using some exotic wiring on being able to switch from 2ohm to 0.5ohm for competition via a switch so i do not have to rewire for an hour at every show. I see some copper made 80A relays. What i want to know is this, here is my scenario- Maximum burping current draw can be up to 85A AC. So i opted to use 2 80A relays per speaker in parallel for 160A of heat dissipation. Since Relays only use 10AWG quick disconnects, will quick disconnects be sufficient enough for this wiring? I plan on running modded inserts for 4awg wiring off each terminal of sub to a junction block. Then from there, 10awg to each relay pin, output to another junction box of 8…

I was planning on this amp Hifonics BXi 1606D - Hifonics 1 Ch 1600 Watt RMS Amplifier http://www.woofersetc.com/index.cfm?fuseac...Product_ID=3804 However, now it is crunch time to buy it, so I am having second thoughts. How would this amp be for two TC-7's. http://tcsounds.com/tc7.htm Should I consider something else? I am going to run it at 1ohm, so I think this will be good. But, any other amps better for under 300? I really dont want to pay more then that.

I checked my battery, nothing is touching + and - I checked the amp, the power wire and ground fit nice and snug with no loose strands The amp worked last night......all i did was unhook wires, move it to the trunk and hook the wires back up....I'm at a loss The only thing i can think of is its somehow shorted in the amp, but i didn't shake, tip, etc. since last night...i don't think the power wire is cut since i turned the car on and the fuse in the engine bay is fine. I have an AQ1200D and two SDC2.5 subs by the way.

Amp under 420 that'd be good for my ia death penalty one that'is has sub sonic filter etc thanks was looking at hifonics brutus 2100 what sub sonic filter do I need it says up to 35hz not sure what to get help Was in between the Brutus 1700.1 and Brutus 2100.1

hey guyz.. having a little problem with my 4200 avh pioneer. I pulled it out doing some little maitnence and then when i put the wire plug to the back of the deck and started it it wouldnt turn on. I drive a 06 escalade and i have to use a wire harness with a interface on it. so what i did was make sure nothing grounded and re connected the power ground and constant yellow and still nothing. then when i unplugged the interface and plugged back in it turned on for about 5 seconds and then shut off again. Could this be a bad interface? or what could it be? please help. thanks

Going to be running an alpine pdx-f6 (60amp fuses), and alpine pcx-m6 (80amp fuses). Would 0ga just be over kill? These are going in the rear of a crew cab colorado and splitting at a distribution block. So it will be ether 0ga in and 2 4ga out or 4ga in and 2 4ga out. Thanks

i've found one on ebay.de what do you guys have to say about this amp ? i also have my eye on a RF punch 400a4.

I am looking for 4/0 wire. any recommendations for this type of wire. and where to get it

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.

Hey everyone. Does anyone have a good used amp for sale? Mono block 2ohm between 500 & 1000 rms watts.

"A second battery is never a good idea as it's an added strain on the alternator to charge two batteries AND supply power for the car. The ONLY time a second battery is useful is if the audio system is to be used with the car off."
