Okay so im putting in a new system in my car and i need to know if there is a reason to buy a crossover and put one in. Ive been told that this crossover is pretty good http://www.sonicelectronix.com/item_8160_AudioControl+6XS+-GRAY-.html. What is the purpose of having a crossover like this? Any help will help. Thanks

1st the alarm ? is how many of u guys dont have alarms and live in not so safe neighborhoods? like i live in a not so safe area of my town w/ no alarm and my sub sittin in the back seat and the amp bolted between my front seats w/ no alarm i worry but not that much cause im usually awake all night and can hear my old doors squeak if they open but if sumone did get in it it would take 2 people to get the sb out anyone else go unprotected? 2nd is about amps in a few weeks i will be getting a new amp and h/u. if i can find a used sundown or a refurb at a decent price i for sure want that. as of now i only need 1000rms but i wanna get enough power to not have to get another …

ok so last night and all day today everythings been great. setup has been beatin pretty good. ok so i went to my ol' lady's house today and had no problems what so ever on the way. my car set for 4-5 hours. i go to leave and my car wouldnt start. thought it might be a loose batt terminal checked that didnt work. my voltage meter said 12.8 turn the key and it would go to 0.0 then to 9.0 and back to 12.8. ended up using a jump box to get it started and voltage went right up to like 15.3 with the headlights on. if i turned my volume up over 1/4 up the stereo would shut off ,lights would dim ,and voltage would drop to like 9.0 ...hit the highway and i could turn it bout 1/2 w…

Hey everyone, I've got this irritating alternator whine ever since upgrading my front stage, hopefully someone can give me some insight. Here's my setup: 02 Lexus IS300 Alpine CDA-9856 MRX-M110 RE SE 12 *SPR-17s *PDX 4.150 *KX3 crossover The items marked with asterisks are new components to this install (owned them since ~07, sat in the closet for a while) and are where the noise is coming from somehow. I've searched extensively for resources to find anything I could do to fix this issue but to no avail. The most comprehensive guide I've found is at http://www.termpro.com/asp/pubs.asp?ID=121 but I've tried everything (new to me) that they suggest, bu…

Just wondering where I can purchase this amp?

I have an older Rockford Fosgate 500.2 unit and I had some questions about setting the gain. Everything I have read shows to take the RMS wattage X the ohm then get the square root of that. My only problem is since my amp is technically a 2 channel I am wondering how I do this with it in bridged mode. That wouldn't normally be an issue aside from the fact that this amp also has a left and a right gain control. Now the amp is 500 RMS x 1 at 4 ohm bridged OR 125 x 2 @4ohm stereo. How would I go about using a DMM to set these gains as close to perfect as possible?

Alright, so I got a dual 4 skar vvx 10 and ive been looking for an amp for it. I was looking for something that put out somewhere around 700-800watts @2ohms. My price range is nothing higher than $230. I have a list of my choices, so im politely asking if you guys could give me your 2cents on which amp(s) would be my best choice.

i have an 03 b5.5 sedan, just wondering if anyone knows how on earth i should access the alt and where in gods name i can find the engine-->chassis wire.... its like a jungle in there... links/pics greatly appreciated.

anyone know a good place to put an amp in a 2004 chevy silverado. and if there is anyway to run the wires without removing the front seat. it is a ext. by the way.

Does anyone have or have experiance with this CD Deck? I have this deck in my car right now and like it alot. I just bought an iPod online today for my car being the deck has a USB connection. Anyone running an iPod in their car? How does it work? Can you control it from the deck?

do I have to have a fused distrubution block for my power wire.

I just installed my EA HO Alt and this thing is performing very well. Limiting factor with installing it is the factory limiter at 14.1 volts. I spoke with Nate and he said in order to get the most out of it 14.8 -15 volts I would have to return it so he could adjust the regulation and then run it using the external regulation. No big deal, but my question is this. How much of a difference would my system notice running at 14.8 volts than at 14.1 volts? I'm thinking it should be minimal, but I wanted to ask others and get some input. Thanks.

Hey I got an amp that says its minimum impedance bridged is 4 ohms, and will produce 1000w at 4 ohms bridged. Ive been running 2 dual 4 ohm subs to make the 4 ohms bridged mode, but due to power limitations I want to take out one of the subs so I can get more power to push a single sub. Since the amp does 1000w bridged at 4 ohms, would it be safe to assume that if I wired a single sub to run at 8 ohms, it would produce 500w rms bridged? Edit: by power limitations I mean I'm running my stock 80 amp alternator, no spare battery and no big 3. so my subs have to split somewhere around 400 watts, id rather just push one at 400 watts than 2 at 200.

I'm in a quandary. I need to make a quick decision on amp. Equipment I have is 220 amp alt, big three done, two hc 2400. Subs are two fi ssd dual 2, box tuned to 45 Hz. I plan on competing in s3 and trying to decide which amp to get before pre-order ends. Would you go with the saz-2500 or the saz-3500. All info and suggestions appreciative.

So I hooked back up my amplifier today and when I turned the headunit on and played some music I realized that no bass was coming from my subwoofer and my amp was in protect mode. I also noticed that my lights would flicker and dim and why voltage dropped to like 12 volts. Any suggestions to what the problem may be?

so i've seen videos and people have a little digital volt reader on there dash, it reads how many volts the battery (or alt?) is putting out, and it has blue numbers... where can i find one online and what are they called exactly. also, i can't exactly afford 1/0 gauge power wire set from street wires, which is who i want. and i can't wait any longer to get my system put in my new car. i have a SAE 1000D amp with a 12" Fi Q going into a 2001 grand cherokee. stock alt is 100amps. anyways, i used the 4 gauge in my previous car, even though it's rated for 600w, thats what people on here told me to use. i wanna upgrade my system to a BTL or Xcon, i haven't decided yet, but i …

I'll start by listing all the equipment used in the vehicle (2008 Dodge Caliber) and say that all of this has been installed and working fine for months until tonight. Starting up front, we have a 230amp DC alt, hooked to a factory replacement Duralast battery under the hood and the big 3 in 1/0. There's a fused power wire running from said under hood Duralast to Kinetik 1400 in the back near the amplifier, then on to the amplifier which is a Hifonics bxi1606D wired to 1 ohm. This amp is powering a pair of D4 Skar VVX12s. Now on to the problem, tonight we started the car and immediately noticed a sound/noise coming from inside the amplifier on the power/ground/speaker ter…

I have stock s10 electrical and have 2 new alpine mrp-m500's. I have went through 2 alternators and wonder what is happening. Is 1000 watts too much for a stock electrical system. Thanks in advance!!!

Anyone have any experience with grounding a second battery or amplifiers in the back of a 2005+ mustang? I know that I could always run the ground from the front battery to the back, but looking to see if there is a good ground to use in the back.

anyone have any hands on experience with the Soundstream HR crypt 4 amplifier???? need some good power for my 2 sets of JBL 660gti components and want clean power with no background noise..my JBL GTO 75.4ll sux nuts for background hiss is the HR crypt 4 worth the money??

Okay guys so I got a 2008 ford escape and right Now I'm running two 12" Pioneer Premier TS-W3001D4 in a sealed enclosure. They are powered by a crunch 1500.1 mono amp. I am most like going to be selling the amp for around $150. So my budget will be around $250-$300. These subs do 1000rms a piece so I'm looking for around 1500-2000 rms. I am aware that I will have to upgrade to 1/0 gauge everything and prob get a capacitor but I'm willing to deal. I have been lookin at some hifonics amps that do around 1700 rms at 2 ohms and they are around 300 on some sites. But as always I appreciate any and all suggestions thanks, Nick

I have a Sundown Audio SAE-1200 amp running 2 SA15s. I'm having a problem getting sound out of my subwoofers. At first I had a Pioneer 4100 DVD when this first started happening. The Subs would cut in and out, then finally stayed off but the amp stayed on. So i had my local shop check the voltage and they said no power was going through my rca's. So I had a different cd player and installed it. After I installed it everything was working fine again. Then today the subs started going in and out. Right before the subs went off, it sounded like the subs were crackling but still had sound going through them. So i turned down the radio and they stopped working after i tried tu…

I traded a friend for this beefy mechman 270 amp alternator for my truck. It just looks so much better... What do yall think?

I have a 1997 Grand Am and this is what the electric consists of, stock 105a alt, deka primary batt, 1/0 for batt to chassis ground and motor to chassis...havnt yet done alt to batt. My voltage is dropping to 11.5 on some notes, the amp is a saz1500....I need help deciding what else I need to get the voltage up and stable. The XS power d1200 I can fit under the hood as primary but the d5100 is to big and I dont want to do a second battery. Should I get the d1200 or get a h.o. alt, if you guys need any more info please say. Thanks for any help
