what battery should i get for the sundown x series ??

So I'm about to purchase a second battery for my car. My questions are the following. Only one fuse is needed (just like in my current setup, same one I currently have)? and it still goes between the last battery and the amplifier, no more than 12" away from amp, correct? The batteries are very close to each other (trunk), do they need to have their black (ground) terminals connected to each other or can each battery have their own ground? (I know for the red (positive) they must be connected to each other or else this wouldn't work). No problems if my main battery is a D2400 and my second is a D3100? After plugging in the second battery, should I let the car ac…

Has anyone used a Duracell Platinum AGM battery before? It's the largest AGM I can fit under my hood, 94r. Sam's club has them for $169; http://www.samsclub.com/sams/auto-grp-94r-h7-agm-36-mo-free/prod9510086.ip?utm_campaign=bazaarvoice&utm_medium=SearchVoice&utm_source=AskAndAnswer&utm_content=Default Ford put the smallest battery possible in my car to save weight, I'm thinking they counterbalanced that by using a 150A alternator. There are two pieces that hold the battery in place that, once removed, accept a 94r. Should I go for this battery or does anyone have any other suggestions?

I'm starting a new build with tax returns and was wondering what kind of electrical upgrades I'll be needing. Q1-4500 and a Q4-90. Subs will be (2) HDC4 12s (if I can fit a 5cu ft box in my Cavalier and have room for the batteries) or (2) HDC3 10s. Was thinking HO alt obviously, I think 270amp is the biggest I've seen for my car. 2 runs of power and ground, big 3 obviously and 3 batteries in the back. Will that be enough?

Title says it all. It might protect when I first turn the ignition on,sometimes low volume,sometimes full tilt. Mind blown about it. Readjusted the gains,checked my connections,checked voltage at the amp,lowest I seen it was 13.4 full tilt

Has anyone experimented with these? If so, what brands? I've read some promising things, and for the prices im seeing I'm willing to scrap my sony to give it a try. http://www.amazon.com/gp/aw/d/B015IVIN9U?psc=1#immersive-view_1444557020300 Random example. Seem to be becoming more popular lately.

My sister is looking to add a sub and amp to her 07 charger. She came to me and I showed her a few things. Prices are too high. I'm trying to get her into a single 12" ia lethal injection or fi Q possibly icon. So we're looking at around 1000 watts rms. showed her the sundown 1000.. Too much ($289). What do you guys recommend in the $150 or so range for an amp? Is something of fair quality able to be had new for this price or is used the route I'm going to need to take? Just looking to toss around some ideas and see what others have had experience with. Sub choice is pretty much set. I have a friend with a single 12" fi Q and she liked how it sounded. Absolutely hates ho…

I can pick alternators for $20 at my local yard, for an extra hundred odd amps would getting a bracket fabbed be worth it? Not planning to exceed 3k rms for a year or so. Just a hifonics brx 2k and a taramps 250x4. Suppose I'm askin, how much would a bracket and a longer belt run me?

Anyone know anything about the old Sony XM7557 . And what would be a decent price to offer someone. Someone i know is selling one and asked me to make an offer

Long story short, my system has been under construction for quite some time. I decided to throw some speakers in the doors via the factory speaker wires just to have something to listen to, but there was no sound. My first thought was a short somewhere in the wires, so I wired one speaker directly to the HU's harness (literally at the back of the HU, not through harness adapter) and it still produced absolutely nothing. I played around with the settings and couldn't find anything that could cause this. Am I missing something stupid, or is this HU fried?

Need suggestions for my Evo X. Double Din suggestions. Less than $600

I mean exact wiring for this...i feel like it wasnt done correctly bc we are incorporating the crossovers into the mix. STOCK HU. Rockford Fosgate 3sixty.2 Crescendo 800.4 Crescendo 1500.1 2 sets of Mezzos. 4 tweeters and 4 6.5's Fi Q D2 Im not sure why, but my guys that helped me out with they system incorporated the crossovers into the system. I thought the 360 could be used instead of crossovers. If someone has some time and would really like to help a fellow car audio fanatic out, how would you wire this setup? I would love to see a diagram drawn out!

I am wondering how to go about wiring 2 older fin style rf bd 1000.1 amps to a single 18" old 3 stack Fi btl. The sub needs a recone so I could get dual 2 or 1 ohm coils.both the amps have the spot for the sync cord.the real question I have is one amp to each coil @ 2 ohm? or get the dual 1 ohm coils and run both amps in parallel to both coils in parallel? I never used the bd sync cord, don't know if I should trust it? I don't want one workin harder than the other.as u guys know I'm looking for a 2 ohm load on these amps. Thanks a ton for any input!!!

Where can I find a Soundigital micro amp for sale? I feel handicapped, all the pages are in a different language, and I can't seen to find a vendor. I'm looking for a two or a four channel small enough to mount in my dash. Wanted a zed micro, but it's a little more than I want to spend at the moment. Been looking at one of these and running it bridged http://www.amazon.com/Alpine-KTP-445U-4-channel-Power-Amplifier/dp/B003VVYL46

Is it ok to use only two channels of a four channel amp?

I was just wondering if this is bad for my car. I have two sa 12s and a hifonics BE2500.240a mechman alternator, big 3, zapper d2400 and a xp750. When I was playing Elie Gouldings "High for this" decaf after the bass drop my voltage shot up to 16.4 Is there something I should do to.regulate it? Or will it be.fine if it happens again?

Sorry, the topic may be a little vague. I've recently found myself researching amplifiers as I may be replacing my zapco c2k 9.0xd amp shortly. I have 2 12" dvc subs with 1ohm per coil, and they handle 1800wRMS/ea. they're situated in a 4.2cu/ft box tuned to 30hz. The zapco puts out around 2200wRMS and I was looking for something a little closer to the subs rated input or over. So I've been working on a spreadsheet to compare different amps to try and discern a value. This task has been pretty difficult, most of the amps I'm looking at seem to be extremely similar or clones of one another? My understanding is that an "OEM" would reach out with a chinese or korean manufac…

So I've been researching ground connections, always trying to learn more about a subject, since I was upgrading some things its always a good time to refresh my memory. I've basically come across several ways suggested to make a good ground, and there are a few that stand out to me. 1) Using dielectric grease to seal moisture out of the connection area, with the idea that when you crank down on the nut to secure a ground lug to the chassis it will push this grease out of the way so the metal connects properly together and helps seal out moisture. 2) White lithium grease. I've seen this mentioned several times, but I truly feel it may be an outdated recommendation. …

Amps that have a clip light ie sundown is that light accurate? What's safe a small flash a little fast fashing solid red? Gain was check with a oscope and a dd1 in the past.. Still clip light comes on

Okay so maybe this is a stupid question just because the amount of power should be fairly close to one another. But I have 2, 15in zcon d2. And im going to buy a new amp,next week. I was thinking of cresendo 5500 and running it at .5 ohms like i am now. But somebody local to me is selling 2 svc 3000. If i strap them ill be doing 6k at 2 ohms. Or my origin plan of crezenxo amp which is rated for 5850 @1ohm. Since im running that at .5ohms not,sure how much ill actually be getting theres no spec on .5 ohm. So my question is which way would be better or does it not matter since theyll be pretty,close? Is this just going to be what brand i choose to run or is there more pro…

Should I still bother with a frame ground if all my amps have direct positive and negative from the battery? My sub amp current has direct runs to the battery of 1/0, which are both less than ten feet.

I can pick these suckers up for 195 each locally, 12v and something like 1200cca ea, anyone every used these before? https://m.interstatebatteries.com/product/26-4163958589-4163958502-2147384763-4294492278-4251616327-4163992330-4163958586-4163958484-2147384903/8D-MHD Considering two for my truck because the price is DUMB considering they're 130lb deep cycles.

Hi Im trying to replace my factory battery with an XS Power one. The one and only battery (according to the XS website) I can upgrade to is the D4800. However, I contacted them to verify this and they told me it would be recommended to make some measurements just to verify this. I went ahead and made some approximate measurements (since I did not want to deal with removing all this wires at 11pm) The measurements I got were the following: Height: ~8" Length: ~12" Width: ~71/2 These seem to match the dimensions from the D4800. However, as you can see in the following picture, right next to the bolt there seems to be another hole (RED arrow), it appears to be…

I am going to be running a Pioneer 80prs with front and rear RCA output for my front stage. I am going to have two amplifiers for my front stage. How do I go about my lack of RCA signal ? I know I can use a processor but is there another way to go about it and not be poor quality? Thanks for any help
