I was planning on buying 4 of the C&D High Rate 100 lb batteries for my car. They do something like 140 aH. I can get them for under $200 shipped each. I was looking into the d3100 batteries along with other batteries which are almost double the price. How much of a difference is there between the C&D batteries and say the d3100? Is it worth the extra $700 total I would have to spend? I am powering 4 of the saz1500s, 1 100.4, and 1 120.2. I have a 260 amp alternator. Let me know what you think.

what's the difference between deka 8a31 & the deka 9831?

I currently have an Alpine 9843 HU in my car which is currently powering 4 Infinity 6022i's. I want to get two 12" BL subs and will be powering them with a sundown 1500d (will be getting a 2nd one when i get more money). I have about 400$ to spend on a new headunit, and would like to get a motorized DVD one, but if i can't get a decent one i'll just get a normal CD player. So, do you guys think i'll need a new HU, and if so any suggestions?

Hi everybody, I'm getting rid of my rear speakers : I can't hear them with my 15" Icon playing! I will only keep my Focal 165 KP front speakers, but I don't want to go active. What should I do? Keep my current 4 channels amp and bridge it to the Focal? (This amp puts out 2*225 watts rms) Or sell it and buy a 2 ch amp (to save some power , and maybe some space and weight) I was looking at the Sundown amps : 125*2 or the 100*2. What do you think? What would you do?

So I was removing one of my RCA cables from my SAX-1200D and the input pulled out of the amp. It was still connected to the wire but it would not screw back in to the amp. While attempting to screw the input back in to the amp the solder joint broke off the input and now I am stuck without an input. Basically I'm wondering if it's okay to run the RCA's from the bridged input and output if the amp is not bridged. I have tried running it from the bridged inputs and it works fine, but I don't know if it's healthy for my equipment. Any help is appreciated.

I'm wanting to run my sundown 3000 at .5 ohms and was wondering what I need to add to my electrical or what could help. Right now I have 2 c&d 77 ah in the back, factory batt up front, 220 amp alt, 2 runs of 1awg. Thanks in advance.

Does anybody know of any really good double din's out there that have everything u need for a sick system?

CADENCE ZRS-8000D what do yall know about this particular amp past or present history. I know their old stuff was the sh@t but how are they so far as quality now? I see them for about 600 shipped and its strappable @ 2ohm plus its not a bad looking amp. Wanted to run 2 fully loaded btl12s in my Thunderbird tuned to 32hz. Wanna totally seal off the enclosure to the cabin as well. Trying to make a nice GP.

believe me i know this is a stupid question but i had an argument with a guy from a mechanics shop and he doesnt believe me: if you have 2 DVC 1 ohm subs wired in series then together to come to a 1 ohm load and run that to a monoblock amp that is rated at 1600 watts rms @ 1 ohm, does that mean each sub gets 800 watts each or do they both get 1600 watts?

I recently had a 3sixty.3 failure and decided I no longer wanted a separate processor. Now im looking into head-units that can give me what my 3sixty did. My setup consists of a set of rockford T5 comps and an Fi Q. When I had the 3sixty I Used my T400-4 to bi amp the T5 passive giving me a the ability to eq mids and tweeters seperatly. I realize that I may not need that and decided to bridge the amp and not bi amp anymore. So with that I need is a headunit with time alignment and a decent eq. The head unit I have in mind is the alpine cde-149bt; it does t/a but only gives a 9 band parametric eq. I guess my question is do you thing 9 bands will be enough?

I have had one of these guys sitting around in my room for a while now. The only info I've ever really found was this thread from 2006. Anybody have any other info?

i have a 1999 mazda b2500 pickup. i am about to install a big three upgrade and was inquiring on a ballpark figure of how much wire to buy. I was thinking around 8 feet or so but how much wire did you guys use?? Thanks, Matt Cusack

Hi Guys , Just one quick question Is the SAZ 2000 really discontinued , if so does anyone know why ? Thank you !

Hi i have a Trailblazer SS with Bose and Nave. I used to use the Pac Aoem gm-24 but i did not really like the output with it. I am interested in going with a different one. I know people probably are going to say just get a new HU but i would prefer to keep the stock one. I have been looking at MTX re-q 3 or 5 but i am open to anything you think would work the best. thanks

Amplifier: Rockford Fosgate T-1000bd Recently whenever I turn on my amplifier, regardless of the vehicle running or any input signal from he head unit, just subwoofer on solely, my subwoofer proceeds to violently shit itself. The noise is absolutely terrible. It's just a one pitch note (pitch varies) and is always extremely loud. This has actually been going on for a while. The noise will happen very sporadically and for different lengths of time. I can go a week without the amplifier doing this or I can go one solid month with the noise every time I turn on the amp, no break. It will also go away for months at a time and then come back with a vengeance. I've figured out…

I just got a daihatsu rocky, and the wife is going to take over my accord, so Im ripping out my stereo equipment. 2 problems though, no room in there for 3 subs and tools, and also, not enough alternator for 1150 watts. I am going to sell my hifonics amp, and put her fosgate amp and RE sub in my accord for her. I am going to get a cheap used 2ch for the comps and take my infinity amp back as well. I was thinking about running this in the rocky and either running the front channels to the coax's, and bridge the rears to one of my 10's. OR I will just run the coax's off my deck and bridge the fronts to one 10, and the rears to another 10. but I am just wondering if a 50A al…

I was going through some boxes of my old belongings and stumbled upon my old school Autotek stash. A 7050 BTS, 7100 BTS and a 7003X electronic crossover. I do not have any other information on these gems (I do know they were made by Zed Audio), and there is very little on the internet about these. I contacted MaxxSonics and was emailed a owner's manual, however it was missing a few pages. I'd appreciate any information anyone has to share about these. Other then having to purchase some new Molex connectors for the speaker wires, I'm looking to put these back in service. Now if I could only find a box with a stash of 9050's or 9100's....

I just picked one up for $150 to run a pair of 10" IDQ D4's and a pair of CDT Cl-5x coaxes in my friends car. Just wondering if it was worth the 150 or not. 4 ohm stereo @ 75 WRMS x 4 2 ohm stereo @ 150 WRMS x 4 4 ohm bridged @ 300 WRMS x 2 all rated at 13.5 vdc

How do I hook up the o-scope to tune my 1. Sub amp, and 2. component amp. I need to know the settings, and what to set the dials on, thanks.

None on the lights inside truck work now and cd player wont turn on.. Should i run a wire from bat the the yellow wire as to get the cd player to work and.bb i think lights i just need new fuses correct?

Today is not a good day. i got my remote gain yesterday i installed it today.. also The plan was to finally have my subs back. i got my DC's back from rusty. and was happy to slap once again... i opened the box and one was broken:( i called rusty and he is so nice... but that's another story. i was hooking up one of the dcs to see if it works and i heard a hum it then everything turn off.. not the car but my amps and the music.... so i check the fuse in the front and its blown. i replace it and then my rf250.2 turns on. but not the merlin?? i took out the merlin and seen the fuses are blown.. so i replace them.... and then when i hooked it up again.. i heard the hum again…

Hello, I just purchased a Diamond Audio D7152 two channel amp. I plan to use it for my front stage which would be the Hex S600s components. The rear fills will be raw midbase drivers from DA's D661 series and they'll be hooked up via Diamond's RAF feature. I'm not sure I want to keep this amp because after getting myself more acquainted with it, it's way too high end for me. It' got more tweaking features than my home theater. I really should have gotten something simpler especially since I only listening to music to and from work. Anyway, lets say I do keep this amp, am I going to need a capacitor or anything else to keep this beauty powered. Am I going to experienc…

So I think I have decided on getting a Q for the new system - either a sealed 15 or a ported 12. I am looking for something to power it now. Really what I wanted to do was a Sundown SAZ-1500D for the sub and a 100.2 for the front stage. However, now were talking around 220 amps to run off my 130 amp alternator. This is just a daily driver so if I can get away with it, I don't really want to get an HO alt. So I am open to suggestions on amps to get? You think I could get away with those two amps without an HO alt? Or should I be realistic and tone it down a bit?

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

Well I really like my current head unit which is a Pioneer 880PRS but I kinda would like to add navigation and DVD capabilities. So I started to think on how I could do it suggestions would be appreciated. I would like to keep the 880 as the primary unit and the nav as the secondary. My current idea is to add a Avic n3 and hook up the audio through an auxiliary adapter something like this http://www.pioneerelectronics.com/pna/v3/p...0_35681,00.html Help is appreciated.
