any 1 know where i can fined refurb RF preferably from a dealer

i hav an install 2 weeks from tomorrow and was wonder what is a good amp for two alpine sws 12d2. i need find a recommended amp for them since i ran them on a crescendo bc2000d with gains half way. thanks to all that can recommend me one. budget for amp is 150 to 250 dollars tops 300

finally got my wires ran and amp hooked up now all i need to do is find somewhere to put the crossovers for my component set. there really isnt any room behind the door panel, would they be ok behind the kick panel (guess this is what its called)? there is just barely enough room for them but they fit. this is where im thinking Uploaded with ImageShack.us

anyone try any of the newer ppi phantom amps? im looking @ the 900.4 and seems like its inexpensive under 200 shipped for 145 x4 and active capable . wondering if they do rated and are clean sounding amps ... i know the oldschool ppi were great would like to try the newer stuff if its still decent quality . any info is appreciated

I installed 3 batteries which one in the engine compartment and another 2 in the boot. Since I owned a small car, I cramped those batteries on the side of the box and its almost impossibel to take them out without taking the whole enclosure with it. So my question is it safe to charge the battries while it is still connected to the amp and the front battery or should I unhook all cables before charging the batteries.

I have someone wanting to sell me an interfire a700.4 4 channel amp for $75. Has anyone used this amp, or something close to it thats made by interfire? Do they do rated? Are they clean? All I have found is this... http://www.interfireaudio.com/download/interfire_catalog_2009.pdf

Ok so I have a 2005 mazda 3. After putting in a saz-1000D and a JL 300/2 (just ordered my sax100.4 which will replace the JL), my electrical couldn't handle it. So I decided to do the big 3 as it is the cheapest route. Well I just finished. And I think there was an improvement but not like I thought it would be. Now when my bass hits my voltage drops from 14.4 to 13.8 sometimes 12.8. This is with the car on and idling. And my lights still dim but not that bad as it used to. My car has a 90 amp alt. Upgraded to big 3 now. So my next step is getting a kinetik or XS battery for the rear to see if this makes an improvement. After I do the battery in the rear I plan on doing…

hi im new her and from sweden, my englis is´t so good so i apoligist for that. now fot the question, is ther anybody who know what 2 saz 3000 strapped giws out in 0,5 ohm mwh from sweden

I ordered a 270 Amp alternator from Singer a little over a week ago, and he said it should be ready for shipment by the end of this week. I'm looking to upgrade my battery under the hood now, and in a few weeks throw another one in the back if needed. there's a ton of batteries to choose from...and from what I've read around on this forum you want a AGM/Deep Cycle batteries but if thats all your looking at there's a LOT of options. So my question is what specifications from batteries should you look at when related to car audio, right now I'm looking at a DieHard Platinum. What specs should I look at when comparing this battery to say, a Yellow Top Optima? Is t…

Alright well does it matter what voice coil gets wired first? I got a ssd15 and it has 3 out of 4 stickers were black... you know the stickers that say pos or neg... but i need to wire my dual 2 to 1 ohm and wanted to make sure it didnt matter what terminal was first

Hey everyone, I have two 12" Fi SSD's on their way...I ordered 1-ohm DVC so I could wire them to 1-ohm with my amp. I found a diagram of how to wire them, but I have a problem. I made my box so that each sub has its own airspace, so I'm going to need a seperate terminal cup for each sub. Would I wire it like this? (I didn't put the terminal cups in the diagram...but you get the point) This is the original diagram I found. I guess what I'm asking is, are both diagrams the same? Thanks!

does anybody no the max watts of the nightshade 12inch 2-ohm, and what is the rms of the 1-ohm?

I tried searching but couldnt find a definitive answer. If I wire three dual 4ohm subwoofers to my one ohm stable amp it will see a final ohm load of approximately 2.67ohms. Specs of my amp are as follows: 600@2 ohm and 1000@1 ohm. So at 2.67 the subs would see less than 600 watts right? I was hoping to get closer to the 1000 watts but Im not sure it will be possible. And to explain my situation a little, I got excited one night and order two 10" Black Fiday subs before I realized they were dual four ohms. Thanks for any help too.

So I've wondered this and never seen any tested answers. If i had a 750 watt amp at 1ohms and another 2000watt amp at 1 ohm and 750 at 4 ohms and I want 750 for my subs given same model and same efficiency at same ohm which would draw more current? A bigger amp wired to 4 ohm or a small amp wired to 1 ohm. Example would be a crescendo bc2000 at 4 ohm vs a aq750 at 1 ohm. Anybody tested this and have any thoughts, experiences etc. Hope this is easy to understand as I tried to word it best I could

Do you guys think $425 for Sundown Saz-1500D amp is a good price. It's brand new.

Had my 4 channel amp sand blasted with sugar sand today, know i just need to decide on a new color. I'm leaning towards a blue to match the the gauge color of my 06 civic ex, but could could do it white and have LED tubes to high light it. Just not sure.

Does anyone have any experience with these amps? Are they reliable? I just bought the little 500.1 to try out in the sq oriented install. I bought it because its so versitile with its wiring options and I got it dirt cheap but I havent heard anything about its relliablity.

Guess what new toy is replacing my Eclipse 8443...................................................... an Eclipse 8454!!! And it only cost me 214$ after tax!!!!! Its was such a steal. From the dealer and everything! I took advantage of a chain getting rid of Eclipse and asked if they had any more HU's available. He was like yeah I got a 8454 that is open box used in a window display(not an actual one where people touched it) and was like i can sell it for 200$. I was like, here's my card!

i have a orion 2500d and it has an intelli W with HPF on it what is it and is it important

This will be going into my scion xb 08. Its going into the hatch area in the back. Question is would any of these batteries work for me. I have no experiance with batteries besides getting stock ones for replacement. I've read up on deka, xs, optima and all those. The only reason I would go with one of the batteries from this site is because I have an account there and they are local. Like I said this is going into a scion xb, will be the second battery. Going to help power a sundown saz1000d pushing a fi 15 Q. http://www.lesschwab.com/batteries.asp I'm assuming one of the deep cycle ones would work for me since they seem to resemble the optimas, but I am lost. And …

Can someone recommend me a good pioneer headunit? I'm trying to keep it on the cheap side, around 100-130 bucks. It will be used in a '95 suburban and i was also going to be running 2 12" L7s (not sure if that matters). I just want it to sound good and go well with my subs.

I'm in the process of doing the big 3 in my '99 Grand Am; problem is, I only have 2 ring terminals to work with right now. Question: If I do the run from my alt to the battery with 1/0 and leave the grounds with the OEM cables until the rest of my terminals come in, will that cause any issues? The current flow to my battery will be improved, but the grounds from the battery to chassis, and engine to chassis will be the same as before. Will this be ok, or should I just wait til I get all my terminals in to do the entire upgrade at once? Thanks in advance

Hey I have a crappy voltmeter from an autoparts store locally that my friend hooked up a year ago to who knows where in the front of the car, I think to a fuse for power just so i have an idea of my voltage.. But I am about to purchase a new stinger voltmeter as I am about to add a new Kinetik hc1400 up front and decided I want a more accurate reading of voltage for my Sundown amp. I was just wondering how you guys wire these up to get a good readout of the voltage? (I guess at the amp?.. ) I'm assuming you would want the voltage at the amp to see how much power the amp is actually getting?.. correct me if im wrong about what voltage i want to read.. so basically I was j…

someone is offering his hifonics brutus bxi 1606d for my Alpine MRD-M1000 should I do it? I know the amp is smaller and will be easier when I redo my box in the nest week, but is it better then my Alpine amp?

Ok so im anticipating the arrival of my SP4 18" and i figured i get everything sorted out for when it arrives... My car is currently running the big 3 with 0gauge wire, 2 1000ca batteries, and factory 120amp alt. The amp im using is a hifonics zeus 3216 (3200@1ohm) and will be temporary until i can get a better amp. Will my electrical be good enough? Do i need to upgrade alt for 3k watts? Or can i just upgrade to 2 xs d3100s? Also what amps would u suggest that could give the sp4 the power it needs to do its job? Ive looked into the crescendo 3.5, dc audio 3.5,and soundqubed 4.5, any other suggestions and recommendations? ?
