I have an alpine cda-9855 and i has the option to use a 7 band graphic or a 5 band parametric.. what is the difference between the graphic and parametric??

I have two U.S. Amps that I have had for years and I am wanting to get the specs on them. I had them installed in another vehicle that I recently sold and I am reinstalling them in another vehicle. Before I sold my other car the 150 fried which sucks, but another reason I am wanting the specs is to find out if it would be worth fixing. The first amp is a US 150 the other is a US 25.

So what would happen if I crossed the power and ground on the amp? Yes, I did this accidentally, for less than 5 minutes ! The amp does have a reverse polarity protect on it, but what damage, if any, have I done? Is it completely fried? I went ahead and put the wires back in correctly, and I still got no sound to my fronts. Thanks for your replies

ok, me and another person on RoE are having an argument on using a y cable on rca. he thinks that using a y cable is not going to do anything to the signal or anything and it is going to be the same as if there where no y cable. while i think and have found on other places online that say that using a y cable can weaken the signal and basic under standing of electricity does back that up. and that is while the voltage is the same when spliting but the current that is carrying the signal is cut in half. so who is correct? and i would post a link to the discussion but RoE has the forum set up so you can't.

Hey guys. I'm just looking at buying the Pioneer Premier DEH-P880PRS and was wondering what people's opinions were on it. Looks like a solid unit for a good price, but I just wanted some feedback/info about it before I bought it. Thanks, Mason

hi, i am going to be getting 2 12" SX and i am looking for an amp for them. they are only dvc2 so the ohm loads it can either be .5, 2 if i get a mono amp or 1 or 4 ohm if i get 2 mono amps. i would like to be as cheap as possable as that means i can get them sooner. which is a good thing. i was thinking of 2 md1d or a md3d if i can find out if they are .5 ohm stable. any suggestions?

What amp would be recommended for 2 18in BTL fully loaded? and where could i get the amp you recommend? thanks guys

what amp would be best matched with a 15" SSD w/ the bp option? orion 1200d RF t1001bd Sundown sae-1000 I can get the orion and rf for about 200 locally and I am waiting for the email back for the sundown. What would you guys choose? thanks for any input -Ryan

I was deciding between a kicker ZX2500, or a Rockford Fosgate t2000. please tell me which you like better or if you have any other suggestions. thanks

Anyone use either of these to intigrate a system to their factory HU. I have a new truck (2004 FX4) and want to keep the factory indash 6 disk cd player but want to install my Arsenal 10 CDT comp set and ppi amps. I just don't think that the factory bass treble is going to cut it for tuning though. Any thoughts (hopefully from others with a similar situation) thanx in advance

Hifonics BXi1606D - 1600w RMS x 1 ohm U.S. Amps XT-4000D - 1500w RMS x 1 ohm both are close in price but the us amps is considered entry level and the hifonics isnt not sure what do you guys think? using them on 2 12" RE SEs at 1 ohm heres the data sheet on the hifonics theres nothing really similar for the XT though

Can get a great deal on one and was trying to get some Specifications. http://www.carsound.com/reviews/amps/zr360.html http://www.crutchfield.com/S-nvAPS3E4lWG/c...;i=206ZR360#Tab http://www.kicker.com/06/tech-support/manu...s/ZRAmpsMan.pdf I know that this is a cheater amp but dose any one have any experience with this amp or any one who has ?

I have a memphis 16-MC2000D The guy i got if from said it was moded? How do i find out it this is actually true?

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

like the title states i am looking for something that will do 1200-1500 @2ohm. i have not payed attention to the amp market for some time now and i dont even know where to start looking. doesnt have to be top of the line but i am looking for a good cost to performance ratio... can you guys help me out?

which would you guys pick? both would be @ 1 ohm, and i just got a kinetik hc2400 as well (for the mini) the amp is for my 12" mt only thing is ive heard the failure rate on the PB is alot higher than the 2500d. my friend has an xa3000, and its broken 2 or 3 times already, even after PB fixes it. it does good power, just i dont want it breaking down on me... i got it MINT for about 200 bux... 400 for the battery and the amp, both are like new, ill post pics later

So I have been browsing around for some decent amps to push 4 18" BTL's and cant make up my mind. Does anyone know if the Soundstream XXX-6500D amp is any good???

well here are some gut shots of my new mids and highs amp. this will be part of an active two way front stage.

Well i just dont feel my arsenals are getting all they can from my Autotek MM1400. I am looking for a good 2000 wattrms amp. I really dont care about the brand and dont want to spend a tone of money. The autotek is a good amp but i know my arsenals can take much more. Any suggestions are appreciated. And yes they are already in a dual port dual chamber box. Also accepting offers on the Autotek.

Hello everyone, I haven't posted here in a while, but I've been keeping myself current on the threads in the build logs section for sure. Some of you might remember my build log, and might also remember that once I got to the point where I could finally fire the thing up, I was having lots of trouble with noise. I tested and tested, and it turns out that it is my JL Audio 500/5 that's to blame (I installed another amp in its place and the problem was totally fixed). It's a high pitched beeping sound that changes evenly in frequency (up and down). Sometimes it actually sounds like a pack of dolphins from the nature shows... very bizarre. It makes this noise in all chan…
