I currently have a 2010 Fi Q12 in a sealed box powered off of a JL 500/1v2. It sounds great, but I want to unleash the sub's full potential by giving it all of it's 1000rms rating. I plan on putting in a high output alternator, so suppling power isn't an issue. The sub is dual 2 ohm, so I can wire it to either 1 or 4 ohm. My question is: Is there a noticeable difference in sound quality if I push an amp at 1 ohm (if stable) vs 4 ohm? The reason I ask is because I was looking at Rockford Fosgate Power amps and the T1000 Constant Power was stable at 1 ohm to 1000rms, while the T1500 Constant Power was capable of 1000rms at 4 ohm. While money isn't a big concern I woul…

So far in my 2001 Ford Windstar I have: 2 Alpine Type Rs Hifonics Brutus 1200 mono at 1 ohm Kinetik HC1800 under the hood Big three upgrade 0/1 gauge wire I just had a new 250 amp alternator installed. After hooking up the radio my lights STILL dim and looks as though the amp is dipping. Why am I still having this problem? I thought I had gone through all necessary steps but I guess I'm missing something? What is next a second battery? Any help or input greatly appreciated. -CHRIS

I looked in the fourms on how to do it but couldent find exactly what is needed. I have 2 xsd3400 batts. One underhood and other in the trunk. What would be my best option in charging them?

Soon i should be running 2 saz1000d's strapped for 1800 at 2ohms in my isuzu rodeo(60 amp alt) big 3 done in 1/0. I have both amps already and i also have one stinger spv44. I will be buying another batt soon, probably a deka intimidator 9a31. Now my question is, which one should i use as the starting batt and which as the batt in the back? im not sure what i should do. I wont have a h/o alt for another couple months also. I know thats probably not enough to run the amps at full power, but i will keep the gains low until i get a h/o alt. thanks for any input! -Max

I need a good head unit that plays mp3s any good suggestions?

I'm running a sundown sae1200v1 at 2ohms running voltage is 14.6 it dips down to 13.7-13.4... I'm running 1/0ga about 5 foot run its cca though all I had for ground was a chunk of 2ga it's about a foot long ran to the frame ... also got a 1/0 ga battery ground to the frame even went to a relay harness for the headlights

the kicker zx1000.1 has a 0-18db variable bass boost at 40hz.. my question is if i want to run my IDQ15s ported and tuned to 28-30hz would the bass boost hurt the sound of the subs?

One of these will be my next amp. The T1500 may or may not be the CP version. I will decide that if I decide to go with the RF amp. Will be powering two DC lvl3 15's.

Hey all I need to re wire my car and move my batts back and get them off my back seat so I can compete.So i was wondering instead of having to take all my wire that I ran out,Could I just use a distribution block as a means of extending my wire?Here is a pic of what I have currently and what Im talking about doing. Sorry for crappy drawings lol.So if you understand what im talking about doing, will it work ?Thanks

Hey there! Just a question, I know amps get hot, but i think mine gets too hot. It will get hot enough to burn the shit outta your hand if you touch it and count to 3. My question is, why? and can i prevent/stop this. I thought the problem was because of its location, it was under my seat, so i moved it out in the open thinking it would get more air and stay cooler. But i was wrong. It gets this hot on my way to and from work, so day and night regardless of outside temp. maybe 30 minutes of play. Its this amp - http://crunchusa.net/Crunch_PowerOneAmp.html the one in the picture. 2050.1 and i have 2 IA Lethal Injection 12's D4. My voltage never drops below 12, never. Any i…

Would two XS Power D3400's be okay to run that? I have high output 270 Amp dc alt. Or should i get two XS Power D3100's?

Hi, I just received a new sundown sae-1200dv2..Hooked it up, runs fine however the crossover is not working properly. My current setup consists of the stock head unit ('06 tahoe) with a Scosche LOC-80 line out converter with the gains set around 85%. I was running a directed 1200/5 before and the setup worked fine. However now using the sae when I turn the LPF all the way down I still hear vocals coming out of my subs. I was told this is because my old amp used a 24dB slope, and the sundown amp uses 12dB. I have no idea where to go from here. Any suggestions please?

ive got some knu concept 1/0 guage wire and i was planning on running it up to the engine battery cuz i figured that would be one of the best grounds i could find but its about 7-10 feet away from my amp and ive been looking around and i read that really long amp grounds were a bad idea? is it true?

would a new saz-4500d be enough power for 2 15" nightshade d1's? if so how many spare batteries would u run?

I have a pretty basic question. I am looking to upgrade the amps I have to Sundown amps. I need to know if the current wiring will be enough and if not what I need to upgrade. I am having a authorized dealer install these so I just need to know what I need to tell them. I have the following gear: Car: 2001 Jetta GL 2.0liter 4 cylinder Headunit: Kenwood KDC-MP438U (3 sets pre-outs) Fronts: Polk Audio db6501 component speaker (max of 125 watts continuous), door mounted Rear: Polk Audio db6501 component speaker (max of 125 watts continuous), door mounted Sub: 10" Treo TE dual 4 ohm sub (500 watt max), mounted in a Ported ProBox Wiring: 4 gauge Memphis 2 amp wiring kit I a…

Okay so im hooking up my new system and i dont know what to get for my fuses or my distribution block. Im going to run 3 amps connected to a powermaster D1200 battery. An alpine 650 mono, 2 channel Rockford punch 550x2, and a Sundown SAE 1200D. What distribution blocks would work? Fuses? Gauge sizes? How would i hook up the battery to the amps and other battery? Anyway, any help will help. Thanks everybody.

My amp cuts on with only the remote wire hooked up to it why? and when i hook the power and ground wire up it wont power my speakers.

I got a brand new aq1200d and after i wired everything up the amp has power and has plenty of it, getting almost 14 volts while the car is running, but there is no signal getting sent out from the amp. Ive tested it with a known good rca cable and even used an ipod to eliminate the head unit but still no sound. I don't know what to check now. The amp is not going into protected mode. Going to call audioque 2night after class and see if they have any input. any advise before i go crazy lol

Okay, i've been reading up on head units for quite some time, some of you know this from older threads. I was going to go with the flip out they have, but then decided not too because of the bad reviews i've read. Then i was going with the iDA-X305S Alpine Electronics of America, Inc. but i don't/won't use Pandora, and it seems without it.. it's useless Let me know if you run it and don't use Pandora, tell me how it is. BUT, now i'm planning on the IDA-X303 Alpine Electronics of America, Inc. because it's not all about Pandora. Does anyone on here run this head unit? If so, how do you like it? I only use my Itouch for music, no CDs.. keep that in mind. Side note, check …
