Amplifiers / Head Units / Processors / Electrical

I knew this day would come but haven't been preparing for it. My battery has passed away. It has been through a lot being the first battery I've had since I got into car audio. I need something new. I am running a JL JX360 2 channel for my mids and highs along with a Hifonics BRZ1200.1D for my BL 15. Its somewhere around a total of 1500-1800 wrms. (When the voltage is up, which hasn't been in a while) I have a Stinger 180 amp alternator installed as well. The dimensions I have to work with are 11"w 8"d 8"h. I was looking at an XS power D3400 or maybe a Kinetic KHC1800. Would these be enough to run as the only battery in the car?? (which is a better choice between the two?…

I have read on a few websites the pro's and con's of D class and Class AB, right now I have a US amps md42, and I am looking to buy a new high amp and really want to try a D class. Anybody out there have any real world experience or advice? BTW, I would like between 150 and 225 watts per channel @ 4 ohms. Looking for a 4 channel. Thanks for any help.

just wondering, I was looking for images for a banner and I found HU's on their site, they resemble on the outside like the first run of RF HU's for a few years ago, anyway here is a pic of the top end unit: B)

Is anyone out there running lot's of power (+2KW) on a stock electrical system?

So does this really put out 600rms at 4 ohms? Or would i be better off with my power bass 400.2? Im hoping to sell my power bass to a friend and buy the ssl for $130 Coments Please!

ok..I have 4 AA 8's and a hifonics amp 2000 watt brtus. My amp will be on and then out of no where it will shut off. then come back a little bit later it started this when it got cold out. Does anyone know why or how I can fix this.

I need some info on these things..I've ALWAYS added an after market head unit to all my vehicles in the past. I've always though that is the best way if you want a good system. Well, I have the chance to uby an 08 Cadillac cts. Clean as hell and would be by far the nicest vehicle I've ever owned...but I'm a bass head. So questions would be.. If a clean sounding, hard hitting system is my goal will the LOC be the wrong purchase? Maybe I have the wrong idea about these things? If an after market setup was available I wouldn't even be typing this but as far as I can tell it doesn't exist. Appreciate anything you guys can add to this, its killing me that not being able to pu…

whats a good 4 channel or a 2 channel amp i have alpine type r speakers or should i just get new speakers while im at it too? need some help

I have a question for you guys I have 2 amps 1 for mids and 1 for highs My question is how do I wire both amps ? Both amps have multiple rca inputs... Mids amp is crescendo 1100.4 and highs amp is cheap kenwood 300 watt amp head unit has high mid and sub rca outputs any help will be great Carlos

Has anyone ever had any success painting or powerdercoating an amp? If yes how did you do it or who did you take it to? let me know. please

My pioneer HU died the other day when I hit a pot hole and now I need to replace it with somthing better. I've been looking at the Nakamichi CD-300,400,and 500 and also the pioneer premier 800 and 880. I know the nak's don't have nearly the features of the pioneer, but I'd kinda like to try somthing different, and I like the simplicity. Do any of you have opinions or suggestions? I'd like to get the best sound quality out of my system without spending much. I've got CDT coaxials (which are awesome for what they are), and a pair of 15" kicker L5's pushed by a kenwood 600w cheap amp. I got the subs mostly because I was young and they look cool and got a good deal, just…

It states 1300 @ 2ohms at 14.4v. I currently have an MD2D on my RL-p 18" @ 2 ohms, but it's only getting around 800 rms. I was thinking of swapping them out, but i'm not to sure on the rated power for the Infinity.

Lately ive been thinking of different installs to get myself into considering i recently landed a decent job. Basically not sure how to hook up multiple amplifiers beyond the 2/3 pre amp outs on the HU. I understand most amps these days are linkable and that I understand.. but what if i want to go farther than that? Where does the signal come from? For example.. say i want to add a shit load of speakers to my door's which would need multiple amps.. how do i go about getting the signal to each amp beyond the front/rear outputs on the H.U? Or say i want to add a shitload of subs to the back which will require more than a couple amps.. arent linkable amps limited to (2) toge…

Hey everyone, I just got my o scope and decided to tune my system. First i did the door speakers since they are ran off the HU, and found I have a max volume of 31/50, all the sine waves looked good, went smooth as butter.... then i went to the sub amp, brz1200d, and i have the weirdest thing showing up on the scope. a picture will be below, or a link. i have eliminated the rca's, hu, and almost all factors with this. even with no signal going to it, and just the amp on, no rca's connected, no bass knob, and i still get a feedback.... please help me figure out why this is happening, i dont want to bump my sub till this is figured out.

im lookin for a headunit for my buddy. all he needs is 1 set of RCA's, and just the basic headunit with CD/MP3 playback. he doesnt wanna spend more then $250. thanks guys!

ive been into car audio for three years mostly kicker but i decided to upgrade i have a rd1750.1 and a sundown nightshade v1 d1 15 i am new to hi end car audio so can someone tell me what voltage my output should be to have my gain set correctly at 2 ohms which is 840 watts and at point five which is 2225 watts please would appreciate the help dont wanna clip my new set up

I love this amp, but there are two questions i have about it. I have it hooked up to a 15in dayton audio reference series RF 15", and this sub is 500w rms mind you, it is hooked up 4 ohms briged, for 2100w rms, and it just seems like it should have more power than it does. It gets really loud, and gets the sub warm if i let it, (only takes about 20-40secs full power, then it smells a little), but it just seems like that if it was doing rated power, the sub would just bottom out and blow in a matter of seconds, it is in too small of a box(about 2-3 cu ft, it needs 8-10 per sub, might be why it dont bottom out) do you guys think im getting full power out of this amp?? and i…

Did a quick search on the forums and came up empty. I saw somebody post a link to one on ebay a while ago, but I can't seem to find it. I'm not positive that that is the correct name... When I say voltage meter, I mean something like this. Feel free to correct me if I'm using that phrasing incorrectly. Just wonderin where I can find the best one for the money.

Im looking for an amp to push two ICON 10s. Im on a budget so I really dont want to spend more than $450. Any recommendations would be appreciated.

anyone heard of this brand amp? is it good? what do yall think about it?

Is hifonics a good way to go for amps?

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...ssPageName=WDVW to power my new ia 187s wonder if it could handle a .5 ohm load... or maybe this ma audio http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...5744820550&rd=1

What ... \only 500 bux http://www.pioneerelectronics.com/pna/prod...6829766,00.html

Amp: 1200x1 at 2 ohms Subs: 2 DVC 4 ohms subs wired to 1 ohm I'm using a DMM to set the gains and my guestion is: Do I set the gains using the formula volts = SqRt of(1200 x 1) or volts = Sq Rt of (1200 x 2) The difference is 34.6 volts for the 1200 watts at 1 ohm and 48.9 volts for the 1200 watts at 2 ohms

I was planning on getting two of these for the 2 BTL 12s Im getting but I looked at the pix and I didnt really notice any fans, does that mean I have to be weary of over heating? Ive had problems with amps doin that before. Also would it have a pretty good or just eh sound quality? Id be using it in a daily set up so yea.
