i just put in my sundown 1500D and it turns on, but nothing comes out of it volts or anything

I have a chance to pick up a Ultra Linear UL1500X for $50 bucks and was wondering if it was a good amp and price? It would be used to replace my Earthquake PH120.2. to run 2 Earthquake dbx10 10 subs. Here are the specs: 1500W Class X Mono Block Amplifier 12-17V Power Input 0.2-8V RCA Input Voltage Frequency Response 10 Hz - 350 Hz Short / Overload / Thermal Protection Bridgeable with second Class X amplifier 24dB Variable Subsonic Filter 24dB Variable Low Pass Filter 0-18dB Variable Bass Boost Remote Gain Control Module RCA Line Output RMS Power @ 14.4V DC 1 x 500W @ 4 Ohm 1 x 750W @ 2 Ohm 1 x 1000W @ 1 Ohm RMS Power @ 17V DC 1 x 750W @ 4 Ohm 1 x 1000W @ 2 Ohm 1 x 1500W @…

Will these really replace a battery?

I'm looking to get a new head unit that will stream audio from my Droid to the unit. 2 Questions... 1. What are the sound quality limitations of Bluetooth transfer. 2. What are my options for the best head units available that offer streaming audio. Goals: I want better audio quality than the crappy headphone out and preferably the least amount of filtering to the signal (I have an H701 to handle processing needs) It would be awesome if the unit featured a digital out for connection to my H701, though it's not necessary. More info available when I get time to type it later

I just installed a Pioneer AVH-1400DVD, Audiopipe APSM-1500d, and Kicker L7 12 in a friend's 2011 Dodge Challenger. It all came together good. Sounded great while playing music off of his iphone and flash drive. And it sounds good when using the radio until i turn the bass knob up (max output at about 750 watts at 1 ohm). The more i turn, the more static i have. I have never heard of this happen before. What could it possibly be?

I got a buddy that just bought a JVC KD-DV7300 H/U. This model does not come with a built in monitor. He is wanting to connect the unit so that the DVD monitor is capable of running all the time. He has a 13" external screen that he has previously used. The unit has a light green wire that is supposed to be connected to the brake line. Is there a way to over ride this? Thanks.

Hello, First to let you know my install that I am having an issue with.... I have a pioneer avh-3200dvd, an sax-50.4 which is powering the IA coaxial speakers in my front stage. The Issue: Yesterday I was going into depth both on my amplifier and the head unit to tune my front stage to my satisfaction. Some 3 hours later, I had gotten it just the way I wanted it. To tune, I unplugged the rcas to pull my amp out to access it, and plugged them back in. The x-over setting on my amp was on full, I switched it to HPF and basically tuned to desire. When I was done, I turned my truck off, then back on, and WHINE, no music playing. Turned the truck off, then into the half posi…

I just got my amp yesturday and whenever I power on my indash or change songs the sub has like a popping feedback that comes through. I have been trying to find similar problem on here and always sounds like people point out a cheap indash as the problem (my indash is a cheap kenwood lol). What are your guys opinions.

well heres the WHOLE stroy on the deal. i seen the aq3500 on craigslist for $300. last week, i texted the guy and asked if i could put down $75 and he hold it for me so no one else would scoop it up from under me. he said it was cool. i gave him the 75. yesterday, he texted me back and said he was moving and needed cash bad and asked how much i had in my pocket. i said $75. he said meet me and the same place as before and its urs for asnother 75. so needless to say i high tailed it to mcdonalds lol. got it for $150!! took it to my local audio shop to have him test it this morning. powers on fine, and plays 100%. honestly i thought something had to be wrong with it but i g…

curious if there were any internal upgrades and improvements to the KX line when the exterior changed

After attending my first bass off in VA last weekend the bug has bitten. Car will be paid off this summer so it's time to start thinking about uprades. I'm not looking to dominate competitions, but I do wanna get way louder. Right now I'm thinking 2-3k would be good for me. Being that I'm running a 5 channel now I know I'll be adding a second amp for the highs. At this point, will an extra battery in back be enough, or do I need to start looking at HO alts? My stock Scion is only 80 amps. Just got a little tax money and would like to put it on something of value towards this. I found a few amps on Craigslist that sparked my attention, although after reading the Stetsom f…

I currently have this head unit http://www.walmart.com/ip/JVC-KD-S37-USB-CD-Receiver-with-Front-AUX-In/15627186 with 2volt pre outs i believe. I was wondering if i upgraded to this http://www.sonicelectronix.com/item_48464_Kenwood-KDC-X696.html with 4volt pre outs if i would notice a difference in the way my system sounded. Higher pre outs are good right??

I currently have a 1000 watt Rockford fosgate. I want a bit more output from my xcon. will upgrading to a 1500 watt amp make a difference? I am planning on buying a sundown from db-r. any input what so ever is appreciated.

I am thinking about beefing up the charging system in my ride. I have a 03' 1.7L Civic, and my amp is capable of 2500Wrms. Big three is done in 0AWG. Eventually, I would like to have a HO Alternator and multiple battery setup. What should my first step be? I feel like I should save up and get the HO Alternator first, as additional batteries, or a deep cycle battery is only a temporary solution. I have been considering purchasing a Yellowtop to put in the trunk for now, and moving it up front later after getting the HO alternator and a dedicated deep cycle for the trunk. I don't really use my system too often, but when I do I like to play it full tilt. Would my whimpy stoc…

Okay so I'm trying to get a estimate of how much wattage I can safely put out without harming my amp's by the voltage dropping. I have a relatively small car, it has a 70 amp alt and I'm not sure about the battery. I was originally going to just run 1000watts on stock electrical but I figured if I upgrade my electrical I can go a little bit bigger. Now lets say I do the big 3 on my little car and I add a deep cycle battery in the back for the amp, how many more watts would I be able to run? And one more thing when you have a voltmeter what is the danger zone in volts? I think it was 11?

I have a 2006 Corolla Type S. My alternator is 70 amps. I have a Batcap 800 as kinda like a 2nd battery for my JBL GTO 1201.1 II amp that puts out 1100 watts at 2 ohms. My system dims a lil bit but not too badly at night. I had a pair of Kicker CVX 12s powered off this amp and one blew and I sold the other one. I also had a pair of Orion HP12s and one blew and I still have the other one. The reason the HP blew though was I was playing Trap or Die by Young Jeezy with my iPods Bass Booste on to make the song hit harder like an idiot lol (I know not to do that ever again). One question I have is could not my electrical system actually be damaging to sub setups? In my…

I posted this on another forum but didn't really get the best answer so I figured I see what you guys had to say First off I am going to be running an 800 watt sub amp with an FI sub (Not sure which one yet) And probably a speaker amp around 100x2 watts I have a 94 honda accord with a 70 amp stock alt, I am going to be doing the big three for sure. What other upgrades do you think I am going to need to do? If I have to upgrade my alt would one from ebay do the trick or is that not recommended? I was looking at this battery for the trunk as well http://www.sonicelectronix.com/item_7324_Kinetik+HC+600.html

Im really looking to buy a FI BL 15, and I want to run it on a JL AUDIO 1000/1. I want to get the DVC 2 ohm. With all options. I have 1 gauge wiring, Big 3, and secondary battery in the trunk. Both batteries are Optima Red Tops. This will be in a 06 Nissan Altima. Is this amp sufficient power to push the Fi? I still have not configured anything for a box. Probably will be at 3.5 - 4 cu. ft. What should the box be tuned to for max output? I'm new to what type of box I should use so any advice will be appreciated. Right now I have a 12W7. I'm looking for SP and so I'm going for Fi.

Well, I'm upgrading, and had plans to keep existing power wire, but think i might stress the capacity of the wire. What I have: 20' of Knu KLMX 1/0AWG to second battery (trunk) [Fused @ 250A] 5' of Knu KLMX 1/0AWG from second battery to amps (distro. block in between) What I'm putting in: Soundstream RUB1.2500D [250A] Soundstream RUB2.600 [60A] Soundstream RUB2.250 [30A] Now, I've read that KLMX is capable of 250A loads, and Kolossus 300A+. Would the KLMX I have be enough to run the amps, if I upgrade the inline to 300A, and run 250,60,30 ANL in the distribution block. [However, 250+60+30≠300] Has anyone ran a 300A load off KLMX, or should I just spend the $100 and get t…

I was wondering when i need to upgrade the electrical in my 00' Jeep Grand Cherokee it has a 136 amp alternator. I have but not installed yet a 12" Fi SSD Sub w/copper coils being powered by an AQ 1200D amp at 2ohms. then i have CDT ES620 comps being powered by the AQ 4X90. Sub getting about 900 watts and the Comps getting 240 watts with gains turned down.

lol :shock: sorry would have got more pics but that damn thing is heavy lol....... let me know what ya guys think

I have a factory system in my new Explorer and do not want to go through installing my cd player right now. I want to keep it all stock except unhook the 8"sub in the back, run the signal to my amp and have my two 15s back there. How would I do this?? Could I simply hook a LOC to the wires that went to the 8"?? Or would the power that is run through that be too much for an LOC, or does it even matter? Quick Quick with the help if you can please, going to try and get this done by tomorrow. Thanks much.

Just got one but how small are they really? It's 11-3/4 inches by 6-1/2 inches? Seems kinda small... Also, anyone have photos of their own collection?

I thought I would post this here since replies elsewhere were slim. I've seen a couple of US Acoustic amps around at a reasonable price and was wondering what people thought about these amps. I know Zed made the first batch of the USX line and them US Acoustics took the plans and had them made in Korea (Pretty chitty if you ask me). I've google this line and people seenm to be happy with them (quality and build), but I thought I would ask around here since it seems that people have a better perspective on the car audio world on this forum. Tell me what you think.

same price basicly.. someone said the 4000x will die if i run it for daily use. i know the crossfires wont.. what should i buy.. i'm kinda eekin to know cus i'd like to order them before i go to sleep. gonna run two powerbase xs 15's dual 2 ohm. 1000 rms each
