'06 Alpine HUs better than '05? Spec wise they look a lot worse.

Ok so I have an Adassa Audio The Warlord amp and I was setting the gains with a 50hz test tone and a dmm and right when I got it at 70 volts it started to fluctuate. It went down to 66v then 60v then 50 and so on. It got to the point where I turned up the gain 100% and it was only giving out 51v!! I shut everything down and waited a while because the amp was hot and when I tried to set the gains again it worked for a while (stayed at 70v) but then dropped back to 60v. I now think something is wrong with the amp. Has anyone heard of this problem? I am thinking about sending it to Chris at db-r.... opinions? Thanks!

do you think that a kicker kx600.4 amp will work for a pair of 12 cvrs. do you think it will sound good. thx

I got an audio pipe 1300 amp. Connected it up and it didn't work. I am now gonna try and return it.

I have been looking for differant deals to pop up for an amplifier for my next build. For power, I am looking for something close to 1kw at 2 ohm, doesn't have to be exact. The sundown sax-1200d has been an option for me from the beginning. Recently, I noticed that the Stetsom V 1K5 is on sale for pretty close to the same price as the sax-1200d. After alot of research, it appears to me that stetsom amplifiers are pretty good, reliable etc... As far as customer service, I'm sure that sundown would win that category. Either of these two amplifiers would be at the top of my budget. Would I lose anything by going with the Stetsom V 1K5? I know it is capable of a little …

will my alternator be able to upkeep a semi truck battery? getting one soon so i need to know. thanks. al

So i bought a 1male to 2 female rca adapter from monster because this hu only has one output for subs...but for some reason i cant access the subwoofer controls or the dolby 4.1 settings on this thing...it appears only in ghost writting not in white...whats is wrong?

If I have one battery, is a good or bad idea to run the negative cable from the amp to the battery? Did the chasis have more resistance than, let say, 14ft of 4 gauge cable? I'm asking that because I read that grounding the amplifier at the battery minimize voltage drop, don't know if that is true.

I have two giant bulldozer batteries in my barn, hold charge fine. All they say on them is Deka 8C12, 90 min, and extreme deep cycle. They are open cell with acid in them so that's why I'm worried. Would they work as secondary batteries in the back?

Should fit over the terminals also? Or what size should I be purchasing? Thanks.

Is it ok to enhance the bass by using the fader control? I am running the front stage off of Channels 1 & 2, the sub of of 3 & 4.

As the title says this will be about the older fosgate 1000.1bd. Im not sure i understand the class"BD" thing? how does that compare to a regular just class D amp? Also im going to have to double check but im almost positive the SSF on the amp at its lowest setting is only 50hz, can that hurt me at all as far as sub performance? i have a box tuned in the 33hz area. just looking for any kind of technical answer to help understand this amp better and decide if it needs to be put up in the garage and replaced lol.

I'm new to this site and had a couple of qestions about the Sundown saz3000d. I have 2 digital design 9515's dual 2's and I was wondering what would be a good amp to place with them? Right now I have 2 audiobahn 2300 hct but I am not satisfied and I was thinking of putting 2 saz3000d's in replace of them. I already know I need to upgrade my charging system. Any suggestions? Dana

Driving my truck with the radio at an inaudible level. Subs just pop. Kinda like an amp with no soft on/off feature. Went to the back and looked at the voltage meter on my rear fuseblock by the 2nd batt. Reads 10.38v. And my subs have engine noise now. What happened? Its a 1991 ramcharger. 318, 220 A alt. And a red and yellow top.

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…

I need some input from anybody that might know, I purchased an aftermarket alternator for my 2009 dodge ram 5.7. I sold the truck and now I have a 2012 dodge ram 5.7. My question for anyone who knows is; will the electrical system of the new ram (2012) handle the aperage and extra voltage (300 amps @ 15.3 volts) ? Also, I got the self excite module to boost voltage to 15.3 volts. This will be the only alternator in the truck. Thanks for any help!

So i got a double din installed on my car and after about a month my system would just randomly turn off(headunit would power off and same with subs and amp) it did it once then would reboot. I took it in they changed the wire harness and the ground. It fixed it for about 2 days i then decided to change my negative battery cable and that fixed it for a few months and then it came back and i noticed that with the head unit turned off that there was a bass note from the subs playing real faint until i turn the bass knob it gets louder. What could be the issue on why my head unit turns off by its self faulty head unit, bad amp need help asap.

this amp http://www.woofersetc.com/index.cfm?fuseac...;product_id=517 OR http://www.onlinecarstereo.com/CarAudio/Pr...ProductID=19580 for an 18 inch fi q

Im getting a 12" FI Q with the cooling package. It will be put into a 2.5 cu ft. box tuned to 31-33hz (cant deside yet). But I really want to know a good amp to power it with that will not kill my wallet or my electrical in my car. Iv got stock alt and bat with a big 3 upgrade and a 5 farad cap. Also I DO NOT plan on running at 1 ohm b/c i want good SQ. Any input is greatly appreciated! Thanks

Ive heard good and Ive herad bad, tell me what you think...Top one is the one I was looking at the 80001NT

my xplod amp cuts in and out. I think it might have something to do with the remote since over a year ago the insulation rubbed off the wire and it came into contact with metal and burned all the insulation off. it didnt work for maybe a week, then when I tried it again it started working but it was real quiet then started working like normal. could it be fixed and how much would it cost? its a sony xplod 1600-GSD (i think) Class D mono amp

Current set up: PSI P2 15" Hifonics Zeus 3200.1d Wired:2 Ohm While listening to the music yesterday the bass suddenly cut off. Check the wires for amp everything looks secure. Check the subwoofer everything looks good. Amp turns on but sends no music. Is the amp blown?

My 97 EB expedition has 4 gauge wire comming to and from the battery. Double that on the power. I am going to replace the ground wire on the bat with 1/0, but the power side is all so beefy I'm not really sure I need to. My deck has a volt meter built in, and I have been playing with it, and wanted to know if you guys think I may need to upgrade the electrical. I have not installed any amps yet and really just want to get a feel for if you think anything else should be upgraded. When idle I sit at about 13.8 V. I don't know how much drop I should expect, but if I open and close all 4 windows at the same time I drop a few tenths of a volt. When I turn on the lights …

I guess the title should be schock sensor but the one i have no has an integrated one. I'm getting ready to put in a PYTHON881XP in the next couple weeks... my alarm I have in right now is a directed automate am5... i have it ziptied to my steering column(I know its a no no)... so where do you guys mount yours?

Alright, read thru the pinned topic for this, seems easy enough..but im doing something wrong.. im usin an old school volt meter but it has "ACV 200 and ACV 500" .. i set it to ACV 200 (AC volts)..the amp is a Sundown SAZ1500D running at 1 ohm so... voltage = sqrt (1500 * 1) voltage = 38.72 ish.. can someone verify that please... so i pop in the 50hz test tone, loud off, bass boost off..volume to 3/4 and I stick the voltmeter to the outputs of the amp.. it tells me 2.8 and up to 5.something at full gain.. something is wrong just not sure what. appreciate any help.
