I tried searching but couldnt find a definitive answer. If I wire three dual 4ohm subwoofers to my one ohm stable amp it will see a final ohm load of approximately 2.67ohms. Specs of my amp are as follows: 600@2 ohm and 1000@1 ohm. So at 2.67 the subs would see less than 600 watts right? I was hoping to get closer to the 1000 watts but Im not sure it will be possible. And to explain my situation a little, I got excited one night and order two 10" Black Fiday subs before I realized they were dual four ohms. Thanks for any help too.

Hi all, So I am finally starting to piece together my audio install. I want to go with a dvd monitor for nav and visual purposes, and have narrowed it down to the following two. I tried looking for some reviews online, but very few single din reviews to be found and a double din will not fit my application. Anyways the two I am comparing are the Kenwood KVT-696 and Alpine IVA-D106. Both are pretty similar in price and feature wise seem to be on par to one another as well. I have always been an Alpine guy in the past, but Kenwood appealed to me as well. I already have the Imprint proccessor, and Sirius box for Alpine from my current setup. Biggest differences are the Kenwo…

Does anyone have an info for me on a replacement gain knob for the audiopipe 1500 amp's? Up till today this amp has been great but it seems the wires inside have came loose and im not the type to bust it open and put it back together.. This isnt my amp its in a good friends car. I have sent emails to the company with no response. Any suggestions? the knob plugs in with a "headphone" looking jack, not the phone cable looking one.

Ok, I got my new replacement amp back finally. Amp has a sensitivity switch between .1-2 volts and 2-8 volts. My new headunit has 4 volt preouts. When I try to set the gains using the 2-8 volt setting I max the gain and never reach 40 volts (1600 rms). I get around 12 volts on the dmm. When I switch it to the .1-2 volt setting gain goes about 1/3 of the way up and hits 40 volts. Will I damage the amp if I just leave it at the .1-2 volt switch position? And any idea's on why if I have 4 volt preouts I can't reach 40 volts on the 2-8 volt setting? Right now everything is hooked up but I have the amp off on the headunit. Waited 3 weeks to get the new amp back so I am really …

First up i bought a decent power acoustic equalizer off amazon and hooked it up but it doesnt work when i turn the head unit from aux back to radio, it has cd/aux rca, sub rca, and front/rear rca's so i have it hooked from my head unit to the amp and back to the equalizer is this right? Second question probably is a stupid one but i bought the nice crescendo 6.5" component set and it came with crossovers, are these needed if i have a equalizer? if so is there a diagram on how to wire the crossovers to the mids and tweeters? thanks in advance

So I have my SAX-1200D and im sure its the same with alot of amps as well. But to my question, 2 sets of RCA's and i understand both of them but they are not marked + - on either, so i dont want to disconnect the wrong ones and fry $$$ any 1 have any suggestions to which jack is + and -?

What is the best head unit, other than the 880 on the market? Keeping in mind I want a simple display like the 880's.

Finally got my BTL 18" reconed!!! only have a hifonics 1600 watt pushing it but when i try to blast it the amp cuts off because its ran at .75 ohms. but anyways, just wonderin if anyone has a american bass 150.1 for sale.....

im upgrading my battery, and im obviously wondering if theres some kind of limit as to how many amps the new batt could be before i start damaging the alt? and do bigger batteries NEED a big alt or would say a 1500 amp batt be ok with a 120amp alt? i guess i just need a batt that my alt can actually recharge.... im really clueless when it comes to batteries and alts any help is greatly appreciated!

I am wanting to upgrade my subwoofer from a my current sub to a single sundown x-15. I have a Power Acoustik crypt 1200w 4 channel amp hooked up to 2 Memphis m-class 6x9s and i was wondering if the amp could handle the new sub or if i would have to buy a new amp to power the sub and if i do have to buy a new one what amp would work well. thanks

has anyone ever used a mono block to power coaxials? i currently have two pairs of planet audio torq 6.5" speakers, wanting to know if it'll work ok running them on a jl 250/1.

Hey guys what up? I have recently start having problems with my HU that I cant figure out. Ive had it now for about 2 years and I notice last that am getting this static, popping noise when I turn my sterring wheel or turn the sub level up. I also tapped on the HU to see if I would get any noise and I did. It seems as though anytime the HU get a bit of a jolt it starts with the noise, whether its me just tapping on it, turning the steering wheel, or turing up the bass level in the truck. Any suggestions? If am leaving anything out just let me know and ill fill it in. Thanks

Planet Audio AP3000D or Audiopipe 1800.1D? Specs on Planet Audio amp are higher than the Audiopipe. This is to push a 12" JL Audio w7. Any suggestions?

Hi guys, I need some feedback on linedrivers for spl. Some say that linedrivers kill subs and some thinks it makes you louder do to up to 13v outs?

Should i use a Kinetik 600 Power Cell in my install for my front stage? -- Will it help with my voltage? OR! Will it strain my Alt? I know its only 400wrms.. but i have the Power Cell already. (2) Alpine Type R 6.5 component sets (1) Alpine PDX 4.100 KnuKoncpetz 4 gauge amp kit Yellow top as starter batt. 1/3 Big 3 done. (Batt to frame) Stock Alt -- 80-100 amp (not too sure)

Currently I'm running off ALL stock electrical in my 99 Grand Am. I found an extra car battery in the garage the other day, and got to wondering. I know that deep cell batteries such as the optimas and kinetics are optimal, but would a regular crank battery help my electrical system out at all? It's not reccommended I know, but I have it and if it would help then I don't see why not until I do get a deep cell. Additional Info: Big 3 is NOT done yet. Running a 1000w Memphis Class D @ 1ohm 1 run of 1/0 power to a dist. block in the trunk with a run of 4g to the sub amp and a run of 8g to the mid/highs amp. Got the 1/0 ground from the amp to chassis Stock batt and alt

just making a general positive statement I recently loaned out my Z800 Ultradrive to a buddy because he melted his Kenwood (ups has it) (they say 225 x 2 @4 and 450 x 1 @ 4, but a shop speced it at 513 or something in that range) and it is a class A/B amp and is not reccomended, like many others, to go below 2 ohms stereo or 4 ohms mono, so what do we do? we wire it up at 1.5ohms mono for giggles, and WHAT THE CRAP :musik05: it played fine, and it still is now a few days later, the top mounted fan it whirling like a foo and the heat sink is getting warm but the amp is holding

i've got a crossfire vr2000d thats supposedly been modded to be .5 ohm stable and handle high voltage. it has 2 hookups each for power, remote, and ground. these all need to be hooked up right? how can i test the amp beforehand to see if i can run it daily at 1 ohm? it should do around 2800x1 @ 1 ohm, and i'll be using 1800-2kw of that for my 12's, so it wont be running full tilt but about 2/3. anything else i need to know before firing up this beast?

Whats your guys opinions on these i know they just came out but we can get preliminary opinions. http://memimage.cardomain.net/member_image...775_62_full.jpg http://memimage.cardomain.net/member_image...775_63_full.jpg http://memimage.cardomain.net/member_image...775_61_full.jpg http://memimage.cardomain.net/member_image...775_64_full.jpg

Hmmm so I was just wondering... Why is everyone so dead set against a cap?

The other day, my subwoofer suddenly cut out and I traced the issue to my subwoofer pre-outs on my Kenwood DDX-319 head unit. Troubleshooting done so far: No AC voltage comes out of the subwoofer pre-outs on the head unit at all Connecting the sub amp's RCAs to the rear pre-out produces sound from the sub (ruling out that it is my amp or subwoofer) There is no resistance (0 ohms) between my pre-out grounds and the case of the head unit (leading me to believe it is not simply a blown fuse in the head unit) Everything else on the head unit functions as intended My head unit is out of warranty by a couple months. I emailed Kenwood about the problem, but …

All my previous amps have had a ssf with a 24db slope I have set 1/2 octave below tuning. My new amp has 12db slope and is 2000 watts more power than my old amp . My tuning is at 33hz on two sundown U10 putting 2500 to each sub so would best bet be to set the ssf at the tuning?
