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

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.

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

im going to purchase one now so which would be "better". this is one part of the upgrade im going to get 2 ssa icons d1 and wire each to half ohm so i need help choosing which one max looking for $500 on an amp.

I'm adding a second battery and want/need to get a battery isolator. The battery is an XS XP750 AGM Battery Power Cell and I'm getting it because I have a 160 amp alternator, NVX JAD 800.4 and Rockford Fosgate T-1500bd. That RF amp pulls 180 amps max (I don't typically listen to sine waves) so I need a 200 amp isolator, correct? Would there be any harm getting the 500 amp isolator because (believe it or not) I can find them cheaper (and in stock) than the 200 amp models.

Hey everyone, I got a sundown x18 powered by a hifonics zeus 1800 and crescendo components to the doors on 600w hifonics zeus. I was running this setup for a couple weeks with stock battery, stock 75a alternator, and no big 3 with no problems at all. With the stock setup, my volts were around 14.2v at idle and when I turn my system up it usually drops from around 13.1-11v and the stock alternator kept up pretty well. I decided to get a new Kinetik 1800w battery, a 175a alternator, and I did the big 3. When I did all of this, my system got worse. My volts were running at around 13.4-13.7 and when I did something as little as rolling up my windows, it drained he volts all…

so I was just curious, as to the pros and cons of either amp... or what US amp would compare to a sundown, or if the even can be compared... I just keep hearing from a buddy, who seems to know more than me about car audio, that the old US stuff is hard to beat.

I've been reading and reading and I guess I haven't really seen it explained in a way that I understand 100% so I must ask. Let's say I have a dual 1 ohm sub, If I wire it in series to a pair of strapped amps each amp will be seeing a 1 ohm load right? When I wire it I simply sire in series to the 1st amp and just run the RCA to the slave amp?

I've been in the market for a new head unit with a screen. I can't get a double din so i would have to get a flip out. Multiple have people have told me to not get a flip out because of my subs. They said subs will greatly damage them. Any truth to this?

Anyone remember these? RFX8250? The major HU boner from a year or two ago? Anyway, I bought one on sale from Sounddomain and have been using it for maybe a year and a half. The other day, the aux input suddenly decided to stop working, and I don

I am looking for a new 5 or 6 channel amp. I need flexible, decent crossovers to run active. Power isn't super critical. High quality is priority #1... Size #2 and Cost would be my lowest at #3. Any reccomendations?

Just recently ordered 25 ft of 1/0 gauge from weldingsupply.com for what I thought was a good price. I just received the cable yesterday and Im slightly disappointed because its deffinitely on the skimpy side. Anyone have any experience with weldingsupply? Im just looking to see if you guys were satisfied with your order.

First question: What is a "float charge"? I've heard the term a few times, but never what it means. Second: How do you maintain a "float charge"? Again, I've heard about it and from what i hear it seems like a good thing, but don't know how. Third: What are some "budget" batteries? I don't need to power a small country, but i would like a decent reserve, as my RF 200.2 beats up on my current battery, a somewhat old Interstate 1000cca. Fourth, and finally: What are some ways to help keep your batteries healthy, or functional for longer? Thanks guys! I forgot to add, that for the time being, i am using a Pyramid 3amp constant/4amp surge AC/DC converter to charge my battery,…

Hey guys, i was looking into batteries for the near future because my stock one just isnt really doing it for me right now. The well known XS brand stuck out to me, and i saw that their batteries have beastly current output, but i was also looking at Optima batteries, and i wasn't sure which is the better of the two. XS has more output for current, but Optima has a "gel layered top", whatever the hell that means. I'm leaning toward XS but if anyone can explain to me the pros and cons of each battery, and whatever the heck gel layered top means, it would greatly be appreciated!

I'm going to buy my gf some components because the speakers in her car sound really crappy and bugs the hell out of me. I need some suggestions on some good sounding 4 channel amplifiers that can be purchased for less than 300. Can either be a authorized dealer or ebay. Any help would be appreciated.

I'll be running a sundown 1200D and a sundown 100.4D to a Fi BL 12'' and a set of hertz HSK 165's Going in a 1998 Dodge Ram 1500. Big 3 will be done The battery that I have now is a Autocraft Silver.. It says on the top something like crank amps at 32 degrees is 935 The alternator that's on there is this: Think I'll be good, or should I get a yellowtop to put under the hood?

basicly when i hook up the 12v source it cuts on without the rem connection and stays on, even if i conncet the rem. i'll recheck it in the morn, cuz its rainin, but yea.

Well I just got back from picking up this earthquake amp. In a little rough shape but it is a ph1000w 2 channel. Any input on this?

Ive heard good things about their amps, and I love the volt meter on the air models. Are the specs accurate on these, and are they good quality? They are dirt cheap, 134$ for the t700 with shipping to AK added on amazon. I was thinking of getting the t700 to put on the Dcons if it would be better then the soundstream rubicon 2.600 that I currently have. Couldn't find any actual reviews on them though. Thought I'd ask for your opinions, lot of smart people here. Thanks guys.

Anyone know anything about these old series 1 amps? Rockford Fosgate 4 channel amp, Series 1 4060x with high and low crossovers - $50 shipped (4x30wrms@4ohms, 4x60wrms@2ohms, 2x180wrms@4ohms) I'm not sure that such an old amp has the best crossovers for SQ purposes but just wanted to see if anyone had any experience with em and whether pricewize was even worth it.

I've had about 3 of them and l loved each one the same, I've had alot of big amps and this lil puppy is the only one that starts to smoke the coils on my DDs within mins of serious play, not enough to blow my 9515s but if you ever need a small amp that puts out a REAL 1500-1800 watts D300hc is the only way to go for 250-300 bucks the only down side is that it does NOT have a subsonic filter and me and other guys like me that loves the sound of a ported enclosure , that comes in handy.. just bought me another one for 80 bucks (blown)
