    Default Need a 4 Channel Low Power 125W x 4 AMP

    Hello All,

    I just bought (4) MM651's which can do 100W RMS and 200W Peak per channel.

    My Car does not have Low Level outputs. I have bought a Rockford Fosgate High-Level to Low-Level Converter.

    http://www.rockfordfosgate.com/products/details/rf-hlc4

    I need an AMP that uses Low Power because I have an Electric Car and don't want to lose too much range.

    I guess I should get a Class D Amp?

    Which 4 Channel AMP do you recommend?

    I have one of these currently that runs a Polk 12" Sub and it works Great!

    http://www.jlaudio.com/jx500-1d-car-...plifiers-99400

    I can either get an AMP that accepts High-Level inputs or one that just does Low-Level and use the converter that I bought from Rockford Fosgate.

    The RF Converter was only $20 shipped. So if you know of a better unit then please suggest it.

    Thanks!

    Sal

    Honestly I'm not really up that much on all the OEM integration gear out there. I always use an aftermarket head unit cause it's just simply the best way to go about it by a long shot.

    Generally you'll want a LOC that also boosts the output voltage so you can get a strong enough signal that you don't have to turn the gain all the way down to avoid the hiss you'll get. The stronger the output signal, the less hiss you'll have. I'm not sure that $30 unit will do that. Audiocontrol and JL Audio make LOC's that will do this. Check out Crutchfield and see what they've got. OEM integration is extremely popular right now so there are lots of options.

    I'd also suggest looking for a Leaf forum and see what other owners are doing. You may pick up some ideas there too.

    Thanks. The most the Other Leaf owners have done is replaced the drivers and added a Bazooka or similar sub.

    I haven't found one yet that has added a new 4 channel amp.

    Last time you told me to get the DL Audio 500 W mono for my sub and it was perfect. I was hoping that you knew of a perfect 4 channel amp you can recommend.

    AudioControl seems like they have a better selection of products.

    Like this unit: http://www.audiocontrol.com/t34/1761...l----LC2i.html

    I just need to figure out if two outputs are enough for my system, I guess I won't have fader controls then. Although I have never used the fader yet.

    I'd opt for the JL Audio class D 4 channel then. Itll be the most efficient. It's only 75 watts per channel but that's enough. Any quality class D 4 channel would fit the bill but the JL will be a little more polished and would likely give better efficiency

    Yeah I guess this is the one you are talking about?

    http://checkout.jlaudio.com/p/xd400-4?pp=12

    I like it and there are sites selling for under $300

    Even though it has high-level inputs I think I'm still going to buy that AudioControl LC2i because it has Auto Turn-on, It gives you a remote turn on lead and it has the patented bass control circuitry

    Mac,

    I need your Help.

    The XD400 needs a 50A fuse and 4Gauge Power & Ground

    The JX500 needs a 60A fuse and 4Gauge Power & Ground (even though in my old car I ran 8 Gauge)

    Instead of running two 4 gauge lines can I run a 1/0 ?

    How many 4 Gauges can be split off of a 1/0 Wire?


    Also, what size Fuse should I put in the engine compartment if I run the one 1/0? 125A?

    And then I guess I can use a Distribution Block in the trunk with two fuses, (1) 50A and (1) 60A

    I also need a power line for the AudioControl LC2i (the specs call for a 1A fuse)

    Thanks Again for your Help!

    Sal

    You could still get away with a single 4 gauge run if is a high quality copper wire. That's 110 amps max which a 4 gauge can handle.

    1/0 is the safest way to go so your initial thoughts are right.

    As for fuse size, I'd run a 100. I don't like to run a bigger fuse up front than what the amps have cause you want the inline fuse to blow first. My RF 5 channel uses a 100 amp fuse and I'm running an 80 amp at the battery.

    Meh, thats kinda misleading. Notice those are lower end brands. Compare Knu to Stinger, Tsunami, Streetwires or Rockford Fosgate and you'll see. Don't get me wrong, Knu is still the best value on the market and just as good as the bigger names.

    Thanks! 1 run of 4 Gauge is a lot easier and cheaper. I already ordered a 4 Gauge Kit from Knu so I'll use that and I'll get a distribution block for the trunk with separate fuses for each amp.

    I was going to hook up a big fuse next to battery in the motor compartment and in the trunk split off the run and install 50A and 60A fuses for the amps. So I'd be protected on both ends. Is that not necessary?

    Right, these all the ones you find you the auto parts stores. I guess those are Knu's biggest competitors.

    Make sure your 4 gauge can handle 100 amps. Not all can. Some top out at 80 while some can do 150. Double check before you start running wire. I'm using some Rockford Fosgate 4 gauge rated at 120 amps IIRC.
