does anyone on here have any experience with db drive amplifiers? someone offered me a good deal on a spa1900.1 but i dont know if they will produce the power they are rated for. i would greatly appreciate any info anyone has on these.

just installed a brand new chevy alt on my mecury van , its chargeing but not fully i ran over my DMM so i cant test it till tomorrow.. theres 2 wires on the alt one is grey the other is white.. 3rd wire is the big red battery wire.. the gray im told is to battery power and white is a exciter wire but am told you dont have to use this white wire because at 1200 rpm itll turn on.. so a quick test and it was chargeing but i was using a test light for the time being and it was lit but not as bright as the vans own alt when i hooked it to van alt it was bright.. not as bright with second chevy alt .. any one have a clue why its not fully chargeing or am i missing something..…

Hey guys I was thinking about going active with my mids and highs and before I buy an active x-over is it possible for me to band pass my mids with my HU front x-over (hp 80Hz up) and my amp x-over ( Lp 3KHz) can I do this or am I missing somethig. My amp is a arc audio ks 300.2 and has a x10 option 50hz to 5.5Khz

i have a lanzar opti 2000d and i think its one of the best bang for your buck! i have used it in all ways 4 ohm 2 ohm i have had it down to .65 ohms for two years never!!! shut down even in the summer with massive audio subwoofers also very good subwoofers has anyone used lanzar opti amps

Alright Everyone Its Been A While Since Ive Posted On Here. Im Saving Up For A Sundown Audio Amp And Basically What I Wanted To Know Is Has Anyone Ordered A Refurbished SAZ3000D Amp From db-r ? I know there reliable but can i trust refurbished stuff ? What Is It That You Do To a broken amp when you get it back? New Everything ? Thanks.

hello, is it possible to blow an amp with a volt. drop from 17.9-13.sumthing?? a friend of mine has a mojo 4k and he only did three burps with it and that was his volt drop is it possible to blow it like that??

I have an 01 tahoe with 2 15's kicker cvr dvc 4 ohm wired down to 1 ohm. Us amps xt 4000 1500rms@1ohm and a crunch 1400 4 channel and a 4 farad performance teknique power cap. red top under hood and db electrical ho alt. Have not did the big three yet. At idle my voltage drops to 13 or even 12 when bass really hits. Will the big three help with 0 gauge wire. Should I buy a powermaster D680 or D975 and get rid of the cap

alright, my girlfriends car has a rf 300.1 to a rf punch P2 12. single 4 ohm(not sure why the place let her buy that combo, 150Wx1@4ohm) I bought a new sub for her birthday, just a resonant engineering REX 12 dual 4. nothing special but it will be getting twice the power at least. it is a ~2.5 ft^3 ported box tuned to 28 I think it was, that I built for her a while back, and I still need to carpet it. RE I havent told her that I got the sub for her, and dont want to tell her. I planned on in the middle of the night going out and pulling the box, carpeting it, and dropping in the RE. obviously I wont be able to bump the system in the middle of the night. I want her to turn…

All right, i have a question about grounding. I have an 1 F capacitor, got it for free and just using it untill i have enough to buy all new equipment for my truck. I was wondering if it would be alright if i grounded my amplifier to my capacitor, and then my capacitor to my floor? would there be any problems in that? thanks, scott Edit: This is gonna be for my sub amp

big thanks to rob. http://www.dcpowerinc.com/ Here are some pics of the alternator. goes in here more pics and video coming soon, just waiting on some terminals

Can anyone tell me anything about this amp? http://viewmorepics.myspace.com/index.cfm?...mageID=19074905 http://viewmorepics.myspace.com/index.cfm?...mageID=19075139

I bought a new Pioneer z110bt and have been messin with installing it into my 2006 Nissan Xterra SE. I keep getting this high pitched whine. The factory Rockford Fosgate system is still in, and I have the bypass harness' and everything is hooked up right but it still makes this high pitched whine noise. Keep in mind this is WITH the key off...........I am lost as to why its doing this........The whine is still present with the RCA's unplugged. Any ideas guys? J

Anyone out there know the rms on the American Bass vfl-175.1 OR has anyone tested one ?

Alright i'm running 4 Dual 4 ohm speakers aiming for 2 ohms. Theory #1: Wire two subs in parallel separate (yeilds 2ohms a sub). Then wire these together in parallel yeilding 1 ohm total for 2 speakers. Then, wire the other two subs the exact same way yeilding two sets of speakers ran down to 1 ohm per set. Now im running one amp. Then run these two sets together in series on the amp yeilding 2 ohms. Only question, wouldn't this i swap the polarity in one set of the speakers??????? Theory #2: Run each sub in series (yeildin 8 ohms a sub). Then run all of the subs in parallel at the amp. Yeilding 2 ohms. I think this is the correct way!! Im going to finish my box tom …

im running 2 saz 4500's to 2 fi btl's and i was wondering should i strap them or dont? what is the purpose of strapping?

anyone have any luck switching to a smaller alternator pulley? Were there any noticeable gains in output?

How do you turn off the demonstration mode???

and I purchased an Eclipse XA2000 for my midbass/midrange. I'll post up pix and stuff when i get it. Has anyone played around with one of these 2-/multi-channel class Db amps yet? Oh and my batteries cell blew so I went ahead and purchased a optima yellow top while i was at it.

ok, for setting gains with the DMM method, do i use 0dB tones, or can i get away with using, say -6dB or -3dB tones? I've heard recommendations for using as much as -6dB tone (that seems a little much to me) so i guess what I'm asking is how loud does most music get? does it regularly hit 0dB, or more like -3, -6, etc?

Focal FP 1.800 what do you think about it? have any of you used it? and what do you think of Focal amps?

What gauge size are the power supply connectors for the sax-1200d? thanks

So I have had my 12" Icon all but a month now and I feel like its time to get it an amplifier that will make it happy. Right now it is being powered from a JL Audio 500/1 and it seems to take it with pleasure. So far it has made a great addition to my Toyota Camry. What I will be doing is upgrading the power for the Icon and re-doing the front stage hopefully in the spring. Basically in the end of my other thread I mentioned a particular amplifier I am interested in and was hoping to maybe get some suggestions along the same lines as that one. The particular amplifier in question is a Boston Acoustics GT-2300. Seems to fit my needs and then some. What I am looking for in…

I just got my sundown 1200D and tomorrow my icon D2 from johnecon should be here. Any suggestions for subsonic and crossover settings?

I have been frustrated trying to track down the background noise on my headunit. Here is what I have: Headunit - Pioneer 9400bh Amp 1 - Kenwood 150.2 Amp 2 - Kicker 500.1 #1 The pioneer when playing a 0 bit track has pink noise from usb and cd. Kenwood amp is powering my front stage and the pioneer is for the back. Fader front and rear both produce the noise with and without both rcas. #2 So I reattached the original headunit and there is no noise with the 0 bit track cd. It is hooked up to just the rear speakers. I have changed the grounds on both amps, changed the ground on the headunit, done the pico fuse fix (wire wrap). I am at my wits end, please tell me if buying…
