All right, i have a question about grounding. I have an 1 F capacitor, got it for free and just using it untill i have enough to buy all new equipment for my truck. I was wondering if it would be alright if i grounded my amplifier to my capacitor, and then my capacitor to my floor? would there be any problems in that? thanks, scott Edit: This is gonna be for my sub amp

so i own a duralast battery and and i want wondering if i could hook a optima gold top to it and have it work fine.. i asked in another post but it was not about this, i just got caught off guard with the original question

I came across Powersurge batteries on the net and after reading over the page and talking to the owner they seem to be pretty legit batts. Im posting this because I want to hear from people who have used them, knows someone who has used them and so on. What do you think of these batts? Legit? Pros? Cons?

Is the RCA out on the slave amp still live or is it defeated along with the other functions IE: gain, LPF, subsonic, etc.? Reason I am asking is with the RCA lengths and the way my amps are installed is it would give me a cleaner look if I could use the RCA out on one my slave amp to the RCA in of the other strapped pair's master. Here is a pic, I want the top 2 amps to be the master and slaves on bottom. I want to run RCA under and between amps rather than on top. I have nothing working right now so I cant check it for myself and dont want to get that far and find out it wont work. Cliffs: does the RCA output of the slave amp still work when strapped? Thanks!

Ok, say I want to use a simple toggle switch to control a relay for whatever reason. Do I grab +12 from any source (battery, ign switched, etc), run it through the switch, to the relay coil, to ground, and hook up whatever I wanted to power using the switched terminals? Thanks, ~Trevor

I am looking to rebuild/convert my CS130 alternator to a high amperage unit. This is for the car and system listed in my sig. What are the limits this case can handle. I came across a 200 amp stator. The biggest rotor I've come across is 140 amp. Will these work together. To go along with this I was thinking about using a heavy duty Delco voltage regulator set at 14.7v, and a Delco rectifier with six 70 amp avalanche diodes. Any thoughts of what the output of this combo would be? Should I get a smaller pulley as well? Thanks.

I'm trying to figure out what electrical setup I need to support a 3000+ watt system. I'm thinking a DC power 270A H.O. Alternator, XS Power XP3000 battery as a secondary, as well as 1/0 through out , of course I could be off with this assumption.

Was curious if anyone knew if this would fit or be able to install in a 2005 jimmy. On crutchfield when I fill in my year make and model it says it cant be installed. This does not make sence to me as its not a huge double din or anything. The response only meen they don't have the kit for it? Maybe a kit for this model to work with a Jimmy doesnt exhist anymore? I don't know why a reg size deck would not work. car= 2005 jimmy 2door. No bells and whistles. standard, no steering wheel controls or anything. 1st piece to go with: Hertz HSK165 6.5 components for front. Fi Q12 in ported enclosure Soundqubed Q1-1200D at 1ohm Soundqubed Q4-120 for components.

okay so heres the deal. i have 2 ssa icons, thinking (going to buy) adding 2... more so here: 4 SSA icons 12's i need amps to power them. i'm looking at spending $750 (about) for amps (would love to only run 2) was thinking about hifonics brutus but after reading some posts they seem like garbage. what amps? another question would be nice to be answer is: how would you go upon hooking up 2 subs to a single monoblock? is it as simple as twisting wires togeather or is it no advised to do such thing.

Hello I need a new complete 4ga. amp kit,and I come across the KnuKonceptz. The Amp kit will be used on a AudioQue AQ1200D.(1200x1) Whats the difference between these three complete 4ga. amp kits? Is it worth the extra cash,or is it a waste? $26.99+shipping http://knukonceptz.com/productDetail.cfm?prodID=KLM-K4 $39.99+shipping http://knukonceptz.com/productDetail.cfm?prodID=KOL-AK4 $51.99+shipping http://knukonceptz.com/productDetail.cfm?prodID=KFX-AK4 Thanks

I am putting in 3 external batteries in the back of my suv. The batteries are obviously going to be grounded to the chasis. I have been confused on whether it would be better to ground the amps to the chasis as well or if it would be better to run the ground to the batteries. The batteries are each going to have 2 runs of 1/0 to the chasis. Which is a better idea?

i'm looking for a amp to power 2 fi bl 18s. well right now im looking at the audioque 2200 for 389 shipped and the audiopipe 3000d for 386 shipped. what other amps should i look at for bout $400? also i'm looking for a amp that has a warranty.

i just ordered 2 kicker L7 12s and idk wat amp wat size amp or wire to use any help would be appretiated

Is it me but I just bought an hd radio and it sounds terrible. I thought it was suppose to be cd quality. I will agree than the sound stage widens and more clarity with the highs and lows. But it's also accompanied with an electronic (synthesized) sound. Kind of like a subtle robot voice in the background. Which I don't experience with analog signals.

I'm building a new box soon for my rl-p 18, and was just thinking of a better way to wire my sub(not wiring it to a different load, just wiring it to one ohm differently. Its a d2 and my amp is a saz1000d. the way its wired now, its just like the image on the 12 volt, wired parallel. the problem is that where the pos and neg go into the sub from the amp, the terminal isnt large enough to cram two 10 gauge wires in. In order to get it in i had to shave a bunch off of it to fit them in. Is it possible to just run one pos from the amp to one on the sub, then run the other pos on the amp to the other pos on the sub since it is a mono amp? thanks

My brother has a 2002 Chevy Trailblazer (4.2L) and he was having problem with his factory head unit. He took it out thinking it was like other units where you can just make a simple swap and have a new head unit. It was a Delco/Bose unit and his Trailblazer has on star. I was told that you would need a different adapter (GMAH24B adapter) if you had onstar. Am needing to know which adapter does he need to buy to get his stereo working again? Or is there a way to bypass that stuff to get the stereo back on like you can do with the pioneer DVD head unit.

Focal FP 1.800 what do you think about it? have any of you used it? and what do you think of Focal amps?

Basically i can tarde my Crunch GP3000D PLUS $400 cash for a Stetsom 7KD in almost perfect condition. Only problem is a slightly bend mounting tab. Right now I have a DVC 2 ohm 12" BTL to the GP3000D and want a nice, clean efficient amp. Next summer I plan to do a wall in my accord with 2 1ohm 18" BTLs to maybe this 7kd if the trade goes well. So for the time being, I will run the BTL off of the 7kd at 4ohms and still be running around 2500 rms. What do you all think about this trade one my end?

i finally installed my system and im looking to get another hu. I currently own a JVC KD-AVX2. I've been looking at other radios and i want a lil more out of my hu. I kinda want a screen, too. I've looked at these models and i cant decide what might be best... Clarion: VRX785BT, VRX585USB JVC: NX-5000, KD-AVX44J

I recently took out my big heavy soundsystem due to the weight in the back causing traction issues up front.( gonna fix that this summer i hope), but for now i took my two kinetic 1800 batteries out. I went out and bought a cheap battery maintainer thing from advanced autoparts, it says 1.5 amp maintain. My question is can i paralled the batteries together and hook both up to this one maintainer or would i need to get another. To me it seems fine, it would still be seeing 12v to maintain. Right?

wonder if I should install my phoenix gold bass cube? we have to play a song supplied from the judges for spl and sq categories. You guys think it would make a difference?

I'm looking for adapters that are 1/0 and have a pin on the end to make it easier to plug the wire into the amps, dis. blocks, etc. I cant find theese things anywhere, can someone help me find some? Thanks

im gonna be doing a install in my girlfriends ride shortly. up front im giving her 5.25 alpine type x comps that have been sitting around. this will be powered with a audiobahn a6004v(don't ask)..anywho i need to know should i turn the amps hp xover to flat or should i just run the amps xover...what do u guys suggest?

So I need help, I have a 2008 ford escape and currently I have my system(2 12"s) hooked up to the stock radio through a line output convertor. I believe that my system would sound twice as good if I was to install an aftermarket head unit. MY Budget is around $100 - $150 and In case you don't know what the escape's retarded radio looks like here is a link... http://fc00.deviantart.com/fs30/f/2008/104/b/9/Tribute_08_pic6_by_Fourthmeal.jpg I am not a car audio professional by any means and I most likely will have to get my radio installed by somewhere most likely abc warehouse. I know I'm going to need a wiring harness and a dash kit. So any advice as to what head unit …
