I picked up a used SAZ1500 for $50 off Facebook Marketplace, guy thought it didn't work. Figured I'd send it for repair, and be into a great amp for under $200. Got it home, fiddled with it, and found that none of the controls work, but if I run a signal through the slave input, it does indeed work. So it's stuck in slave mode. Does anyone know how to get it out of slave mode? I'd love to be able to set the gain properly, dial my system in the way it should be done. AND.... with proper electrical, can this amp be run at .5 ohms? Good ventilation, dual runs of 1/0 to dual 1/0-1/0 reducers at the amp, 250 amp alternator. Am running it now at 2 ohms to my (2) dual…

pretty much straight foward, I am getting 2 Q 15's and I am up in the air between these 2 amps, they are both around the same price and I was wondering some of your opinions on which will push/sound the best with the 15's. Also what is the BP option when you order the 15's? Thx Josh

bought a 1200d from a CA.com forum member in december 2009. hooked it up to verify that it was working in my buddy's car, but it whined pretty badly. all the cables were properly run. about a month ago i built a box and bought a sub and installed them in my truck. the amp has the same whine it did when i bought it and i also noticed has an "power surge", like there's faulty wiring. and yes, the amp is what is whining. i thought it was just the songs we played to test it but apparently not. i relocated then replaced the power cable replaced the ground and relocated the ground with no change. when playing, it's almost like the bass knob was turned down and at random times t…

Any sundown audio zv4 or zv5 for sale? I'm looking for a 15" dual 2-ohm sub, thanks!

I need to choose an amp for a pair of Maw-15's I was thinking the Sundown-1000D. Seems like it would work good being when I wire both subs into it. The Rms wattage would split and it would be powering the MAw-15's to their full RMS which I know isnt everything but ya know. Any Input. Thanks in Advance for all the help.

How does everyone like their sundown amps? I've always heard good things but would rather ask here where I'm sure many have them right now.

Has any body had any experience with this batteries. Take a look at this link http://www.supersportbatteries.com/DualPurpose.html

whats up everyone? so heres a question that i guess is kinda noobish. i recently had some problems with my deck, and after trying to remount it and clean the laser i decided its time to upgrade, so i did. i went from a pioneer deh-3800mp to a deh-4000ub i had in my other vehicle. now, from what i gather, the 4000 is a more powerful output. that said, when i plugged everything in it was significantly louder at the same volume (35). my question is, should i readjust the gains on my amp? i've been fiddling with the deck (still trying to fine tune this one 2Q 1Q 1W 2W stuff), and i can significantly reduce the sub volume, but i'm wondering, should i lower the gains on…

I have 60' (40' clear/silver, 20' blue) of Monster 400 Series 1/0. I need another 100' (40'clear/silver, 60') blue though. So I was wandering if I should bother hunting like crazy for more Monster, which I have been doing, or sell it all and get some Knu Fleks 1/0. Basically, should I hunt for another 100' of Monster 400, or say screw it and get 160' Knu Fleks?

Right now I have a pioneer DEH-P7000BT and I can get a deal on a new pioneer AVH-P5000DVD. I like the one I have now and its features but I would like a tv but i dont wanna lose the features. I was wondering if anyone has any experience with that in dash tv and would suggest it. Any suggestions would be great. Thanks.

Hi, there is a "high" level and "low" level sensitivity switch on my JL amp. The manual suggests to set at "high" but I almost get no movement from the sub until I turn the gain at least halfway. Setting it at "low" seems to boost the signal input and the sub bumps alot more with the gain at zero compared to halfway setting before? I usually set mode slope to 24db as it sounds better to me and center frequency 65hz and low pass around 80-100 depending on size/box the sub is in. Its a sealed 400w 10" that I've been fooling with, so should I keep input at "high" level setting and boost sub eq on headunit and gain more? Or just stick with what sounds best? I have 4v preouts,…

I Have a 2000 bmw 5 series. Here is the setup: 1 15 BTL n2 fully loaded powered by a hifonics 2000.1 All under hood elecrical will be done with 0 awg ROCKFORD FOSGATE WIRING. Stock alt. (I believe it is 160amp) Either the stock batt or kinnetik batt upgrade will be used Do you guys think that the cars electrical will be able to handle it? gain will not be set to max.. I jus wanna be able to make car alarms go off with the BTL hhahaha Thank you for your time

HU: Alpine 9885 (4V) Front speakers: CDT CL-62 (160RMS) Rear speakers: CDT 69X (100RMS) Subwoofer: Fi 12" Here's how I have them wired. Front speakers are amplified, rear speakers are running off the head unit. The rear speakers start to distort at around 25/35 HU volume. Why? Ideally I would have preferred to have my HU @ ~30/35 for PEAK listening levels. But as of now, since the rears distort so early I have my front speakers and sub tuned to peak at around 22/35. Most of the audio is definitely coming from the front and the rears are doing a good job imagining, but I find that I could get much more out of my system if the rears weren't limiting me so much. What are my …

I am wanting to upgrade my system to 2000-3000 watts. I don't know to much about batteries and such and im not sure how many/what size batteries i would need to stay at about 14 volts. Also my truck puts out alt puts out 105 amps, Would i need a HO alt? Just trying to figure things out so i can figure out how much this is gunna cost me.

On my T1500, I'm wondering if I should leave the Infrasonic Filter on or off. It came from the factory with it off, I can't tell much of a difference with it on. Right now I've got the frequency set at around 110. I've heard everyone say to set it around 80, and it does sound a little deeper there, but on some songs, "Late Night Tip" mainly, there are some bass notes that are left out with it at 80. With it set a little higher, I can hear everything. I've got the gain set at 5, and the Punch EQ set around half way. Anyone think I should change anything? Just figured I would see what everyone's opinion is.

just wondering what i need to set my gains at voltage wise with my ac meter for this amp. is it around 80 volts? thanks for any help

My amp is mounted in the middle of my trunk and today i had to take everything out to install some more spl tiles i got in the mail, when i put everything back in and opened my trunk, a drop or 2 of water (it has been raining the past 3 days in st louis) fell onto the circuit board of my t2k...it fell in right by the phase switch. After that when i turned the car on, the sub (FI BTL) was making a awful low scratching noise, at first i figured it was the rca's to close to a power wire, messed around with the rca's which helped a little. I finally figured out it had to have been the water when i unplugged the RCA's and it continued making the noise until i unplugged the s…

Soo i was drivin down the street bumpin and all the sudden my subs cut off, when i checked it the amp was not turned on but the fuse wasnt blown, i took the fuse out then put it back in, the amp turned back on immedatley after. next time im driving it does the same thing and i have to take the fuse out and put it back in to turn on the amp. it only cuts out when i turn it up to a little over half volume. i would just go throw on another fuse but they dont sell any 250a fuses at my local places so id have to order online

Hey guys i was looking around on ebay and i saw this little gem MKll Version Tripath TA2020 PCB 25w CLass-T amplifier - eBay (item 250628158856 end time Jun-05-10 08:20:12 PDT) What i wondering is that this set doesn't come with any instructions and it doesn't specify exactly what cables it comes with. i want to know what will i need to be able to run this setup. i have a pc power supply that i use to power a pioneer cd player, i was hoping that could work? and if anything that i need , please let me know thank you Brandon.

I'm swapping out my clarion 785usb for a nexus 7 tablet (source) with a pair of 2x4 mini dsp for processing. This set up is a 3way + sub. What i would like to do is set the tablet volume to max and then run a volume control potentiometer to control the master volume out of the source (tablet). Additionally, i would like to control the subwoofer level semi-independently. What i mean is that the master volume would control all the channel (including the subwoofer) but a secondary volume control will be used between the minidsp and subwoofer amplifier. So this is something like what i was planning to use, http://www.amazon.com/Axxess-AALC-Remote-Level-Controller/dp/B003FPD…

Ok I got some new Knu Konceptz battery terminals with 4g outputs and I'm assuming I will need to cut the stock terminal out. So soldering the wires will be the best option right? Now I know with smaller wires you usually just twist them together and then solder but thats not really feasible with 4g, or is it? If anyone has tips on doing this it would be greatly appreciated. This is the terminal I will be using.

I was swapping my pioneer hu out and putting my sony back in, and somewhere during the installation something happened, and now my T250x4 doesn't turn on anymore. The board stinks like a dead amp, but the internal fuse is fine, and the inline fuse is fine =[ I am not sure where to go from here as far as fixing it, everything else in the car works fine, and I'm just weirded out that it might happen to another amp. Thinking about replacing it with a PPI900.4 o.O I checked all my wires, even pulled them out, inspected them and re ran them (I only have 6 or so ft of 1/0 power, and a matching ground run to a block, then from the block to the amps). I sorta feel retarded. M…

How the hell do you supply 3-400v in a car setting? What kind of charging system goes with that? Also, whoa.

Im gonna run 2 d1 Dss Ethos on one of these @ 1ohm. How many batteries am I looking at needing for it? Im replacing my alt with a 240a. I currently only have a 55ah agm under my hood. Buddy of mine told me to run 4-5 group 31s for it and a 240a alt. Whats the minumum amount of batteries to make it happy?
