I would like to know about all the different RCA cables like 2 channel, 4 channel, and 6 channel What goes best with a Sundown Audio Monoblock Amp and one sub? I plan on buying a 2 gauge Tsunami Wiring kit and it only has the power, ground, and remote so I have to buy a RCA seperate and I want to make sure I don't buy the wrong one. Thanks!

I have a Hifonics XX-Colossus II, would the new Hifonics Colossus be better or worse? Mine: http://www.sonicelectronix.com/item_5382_Hifonics-XX-Colossus-II.html The new one: http://www.sonicelectronix.com/item_32990_Hifonics-Colossus.html I noticed the new one's CEA-2006 compliant.

I'm installing a Kicker tc104 sub in my trans am and have a choice from 2 amps, either a old school Autotek 7100bts or a Kicker ZX400.1 I just picked up. Which one would you prefer to use? I'm not trying to blow the windows out or anything, just trying to get some better sounds over the stock setup. Thanks for any input you may have.

This company gets crazy good reviews and can charge a multitude of battery types.. Not only that but a 5yr warranty on their product.. Insane in the membrane!! Well I picked up a CTEK Multi US 3300 since I was told at Pepboys my aux battery was "dead" and "failled" their test... Problem I have with it is Kinetik batteries are not rated in CCA so I cannot really go by their testing. Emailed Kinetik and got a response in about an hour to get a battery charger and let it sit for 2-5 days depending on how low the battery was since it's last charge. They also told me if I wanted to ensure most batteries "coming back to life" I should go for the 7000 but I don't think I need to…

Gotta love em batteries.. but its time for something else any suggestions on a good under the hood battery. I've been looking at xs and optima not to impress with yellow tops.

so i have 2 18" fully loaded BTLs waiting to be put in with 2 2400 watt rms hifonics amps....1 amp for each sub... but i need to know how many batteries do i need ?? also what brand / model ?? i know XS Power Batteries but which model ..im thinking the HC2400 for each amp ??. i wanna get 1 battery for each amp ... and then 1 battery for my cars electrical... also how many amps does the alternator need to be ... i know i need to upgrade the alternator.... im pretty sure i wanna go with DC Power alternator ive heard nothing but good things about them... what brand ?? where can i get the alternator ?? also what gauge does the speaker wire need to be ?? 12 gauge fine ?? im no…

Alright, well I finally had time to run the wires and hook up the AQ2200D i bought and hooked up the Volt meter also. When i First started my truck it was at 14.1V(If i remember correctly). that was with no sub hooked up just the amp, along with a boss rev-665. after having the truck run for about 5 minutes it dropped down to 13.8. I still need to do the big 3(i know i should have this done already ), and Im saving up for a XS D2400 for my main battery. What else would i need to keep a stable voltage around 14.4 or higher. I know I should get a HO alt but I just dont have the money to drop on one at the moment. What would yall suggest for me? Thanks! Alex

Okay, so my problem is that my brothers HU only has one RCA output that is currently running to the amp he had on his subs, well now we are hooking up another 4-channel amp for his 4 6.5's he has in his car now. So i need another 2 RCA outputs somewhere to go to the 4-channel amp. *Can I just get 2 RCA line output converter's and tap one into one of the 6.5's in the rear and one of the 6.5's in the front?? He doesnt want to upgrade his HU right now. Any input is always appreciated. Thanks

i got my hands on one.. it should be here in the morning.. i got it from a friend.. his dad has it in one of his old broken down trucks, (rednecks with lots of money) anyhow, his dads, brother did SPL back in the 90's and this is one of the amps he used... he knows im into spl so he asked what i would give for it... i know its a surf borad cheater amp fom years past, i knew them to be a pinkish purple but he says this one is silver, and about 4 feet long, he said the number on it is HC100 .... anyway. its in working cond, what kinda resale am i looking at on this?

Got my temporary ap1500d in the mail and installed. Set the gains via voltmeter, which I know is not the best method but thats what I have currently. Also tried confirming with my ear. Have 0 to 4 gauge reducers both put in, and included a picture of everything. Wired at 2ohms, voltage doesn't drop at ALL before protection light kicks in. The old amp would drop the voltage into the 12s. Gain is not even a 4th of the way up. With the new amp, its not as loud as it was nor is there as much flex as there was with my mtx7801d. Did I do something wrong? I feel this amp should be "putting out" better than what it is.

guys i need your help. i have a sundown sax-1200d powering 2 sa-12s. lately the amp has been making this high pitch noise as soon as i turn my car on, and after 20 minutes of playing it will go into protect mode and it gets pretty hot. is the amp screwed up or is it something else? any help would be greatly appreciated, thanks

So, i had my meter mounted on the left side of the pocket below the HU using velcro. well, that was late last year (cool weather), and now... Hot Weather = the glue/tape on the back of the Velcro melting. so, heres a few pics of my dash. there is nowhere to mount it that i can see. you can see where the trim piece around the pocket is a separate piecs. i have to take that off when i need to get to my HU. so i cant mount it there. ANY opinions wanted. thanks!

A few hours ago I put a Sony Head unit in my friends car. Not sure what model; her parents took it out of their old car. Once it was wired up, we tested it. The tuner was coming in static-y or not at all, depending on how we moved the antenna wire around. It was a 2000 corolla and didn't require an antenna adapter. The cd function and aux function work fine and sounds clear. They listened to fm radio with the factory HU on the way here, with no problem. Any ideas?

Here is my problem. I know the out put values on the amp @ 2ohm(115wrms) and 4ohm(75wrms),what I don't know is the output @ 3ohm which is waht my comps are. Should I assume a midpoint? And effectivly gain down to say 85w(100wrms 3ways and 90wrms 2ways)meaning figure voltage for 85w @ 3ohms and set accordingly. Or do I just need to get an o-scope and do it on a bench?

I was checking out weldingsupply.com, and I'm stuck between #1 and 1/0. Their "suggested ampacity" chart recommends #3 for up to 150 amps, #2 for 200a, #1 for 250-300a, and 1/0 for 350a. But going off these numbers, it looks like at most I'd only need #2, as my amp has 5x 30amp fuses (leaving 50 amps of headroom). On the other hand, this site makes it look like I'd need 1/0 for sure. Sundown said use 1/0 for sure, just wondering if anyone else could weigh in on this, since I can't find a reliable table for ampacity and wire size.

I'm looking at possibly running three 4 ohm subs, which would give me a 1.34 ohm load (of course, you all know this already ). How much power would I lose if using an amp that does its power at 1 ohm?

I have a pontiac g6 gxp and plan on getting a sundown 2500d and was wondering if I will need a alternator and or just batteries.

I am looking to buy a head unit with a built in gps. I want a high end head unit and I am willing to spend around 500-1000. So any suggestions will be appreciated. It will be for a pontiac g6 gxp.

heres my problem, i already have my amps in hand, in question is the mono subwoofer amp which is a hifinoics brutus BRZ2400.1D RMS Power @ 1 ohm 2400 watts x 1 channel i also already ordered my subs which are 3 fi q series 18's, someone brought up to me that with ohm rise i really will only see around 500 watts per sub, and to me thats a waste when thats only half there rated power..so i have 2 options to go from here, by another fi q and end up with 4 18's and buy another brz 2400 watt amp which would really put a strain on me budget wise, or stay with the 3 18's and use the brz 2400 watt amp on 2 of the fi q series and buy a Hifonics Brutus BRZ1200.1D for only $209 and …

new job way more cash! ok so i have been planing a build with some skar 12s changed my mind to put 4 ia ported in my trailblazer. well i did the big 3 i can tell a diff, but thats on a single dr. right now im trying to get the power to put 4 of them. ill be getting 2 kinetik batts under the hood and then another big one in the back. i plan on putting about 1kw max to each sub, also getting a ho alt. kinetik has a charging system also would i need oreven want that? then my trunk space is wide not so long would i be better off walling with them or a sub up port back deal. im not really wanting spl or sq more of a mix of both. im waiting for crescendo comps to come back out …

I installed a fi ssd lastnight. My enclosure is 2 cu ft tuned to 32 hz. At first I set the subsonic filter at about 12 o'clock and I wasn't impressed, the lows were really lacking. I figured since the filter ranges from 15-50 that half way would be 32.5. I turned the filter back to around 10 o'clock and the sub really opened up, I'm very happy with it now. I don't want to harm my new woofer so I'm just curious if I have it set correct. Other info. Hu is an alpine cda 105 (2 volt preouts). Amp gain set a hair over half way. No bass boost and I'd say the lpf is set around 10 o'clock also

i took my equipment out of my car to diagnose a problem. while it was out it was stolen. so now i am stuck with factory power. the problem now though is, the factory system had some issues when i bought it. at a little over half volume the sound from the tweeters cuts out when there is a louder sound.. like a yell or.. scream. or just louder singing. head unit? or amp. 03 z4 by the way

i have a 2010 Nissan Frontier with a 110a alt. right now i have an saz-1000d and 180w 4 channel amp on stock electrical with very minimal headlight dimming at full tilt. will the big three and a kinetik hc2000 near my amp be enough for me to run a crescendo bc2000 and my 4 channel?

So my amp keeps cutting off the power to my subs. It mainly occurs when I try to get my subs louder. It didn't do this as often a month ago. I think it was after a day of delivering pizza with it bumpin all day, amp got hot and my fuses blew, I believe ever since then it's been acting like a wimp. I'm wondering a few things I have stock electrical system, would the amp protect itself because its supply is inadequate? my subs run 300rms my amp runs 900rms, did I ruin my subs which is causing my amp to protect itself? (that would be awesome, been tryin to swap them out but gotta hurt em first) whatever it is, it keeps randomly protecting itself and when I turn my HU off…

I need copper ring terminals and fuses/fuse holders, and I was wondering if you guys had any websites that sold the best ones. I've searched ebay and a few other sources with some luck, but I'm just wondering if there's a better place to get them.
