My 2000w TNT amp blows fuses as sooooon as I put a fuse in. What is the problem with the amp. is it internal external? I also checked my wires and they all look good

Sounds like you're grounded out somewhere. I'd check your main power wire again, make sure there isn't any abrasions or cracks in the insulation. I had a Fosgate amp that would blow fuses everytime they were put in. turned out to be one of the screws to mount the amp to my floor board was grounding it out, pulled the screws and has worked fine ever since

Wire my rockford fosgate rf2002 amp and 12"sub to cobalt

Hi my names Josh. I see you want put your rockford amp in. Assuming you have your factory radio you have some wiring to do. But first you need and amp kit it wil have the necessary wiring you will need in it to wire your amp to your car. You will also need a line level converter they you can pick on up at best buy other wise known as a pac converter. This will alow you to transfer the high level frenquency your radio puts out to a low level frenquency to go strait to your amp through a pair of RCA's thus giving you sound to your amp and then to the sub. Your wiring will consist of the ground which you will have to ground off the vehicles chasis no more than a foot from your amps designated location. Then you have you power 12v which is about a 4 gauge wire and will be fuzed and ran strait to the positive side of your battery and last will be your remote wire. Your amp will have a place marked remote on it that is strickly for you to wire to your radio/ignition source for powering the amp up when radio is on and powering it down when it is off. YOU MUST ISOLATE THAT WIRE with a 12 volt tester it will be the wire that is tied in to your radio to power only when your igniton is on and when you turn your key it should tell you if you know how to properly check for this wire. wants you istolate this wire you will want to tie into to it and then of coarse run it and tie it into your amps remote power again it will be marked remote on your amp. From there all you have left is tying in your line level convererter.. This takes some patience as you must make sure that you do isolate your sound left and right postive and negetive front and rear channels the line level converter will tie into either your front or rear channel but caution you dont get them mixed or you will not have a signal at all. Again my names Josh and i hope you are able to get it hooked up okay.

I have one 12inch 1000 watt mtx sub what size amp should i buy

Hello taona80,

If the 1,000 watts is RMS, I'd recommend an amp in the 750-1,000 watt RMS range, perhaps like the Alpine MRP-M1000 or Rockford-Fosgate T1000bd. If the 1,000 watts is peak power, the subs continuous (RMS) power handling is much lower, probably 300-400 watts. In that case, I'd recommend the Alpine MRP-M500 or Rockford-Fosgate T500-1bd.

When my bass hits, my car lights flicker.

Is the problem much more noticeable when the car is at idle? Double check that Alternator output. 70 amps is not high output, and if the problem is especially noticeable at idle, it's probably due to the alternator putting out lower voltage( a common thing with alternators). Also, with that much draw from your sub amp, the wire from battery to alternator should be beefed up, as well as the ground wire from battery. You can make up your own cables by purchasing the wire to length and wire lugs at a local Welding shop, 4 gauge from alternator to battery is good. High output aftermarket Alternators shoot into the 200 amp range.

if you have both amps connected to the same power wire this will another power wire to the alpine and this should solve the problem.

Need amp for 2 15 l7 4 0hm

Hello jasonjohnson,

There would be more amp choices if those L7's had the 2ohm voice coils, allowing you to series the coils and then run the subs parallel to the amp for a 2ohm load. As it is, you'll probably have to run them as either 1ohm and have limited amp choices, or as 4ohm and settle for a little less power.

An absolutely excellent amp to use at 4ohm would be the Alpine MRP-M1000. At Crutchfield this one is on sale for $347. For more power, and an amp stable to 1ohm, I would recommend the Rockford-Fosgate Punch 1000-1bd, a "factory refurbished" model is available at Crutchfield for $349.99. It's $700 new.

Both of these amps have adequate power for 2 L7's, but the RF will definitely be the better power choice. Both are also well respected names in mobile audio and the prices are reasonable.

If you have deeper pockets and want to push the subs really hard, a Rockford-Fosgate Punch 1500-1bd will put a full 750 watts RMS to each sub.

Hope this helps.

Amp makes noise. I am purchaseing a new amp

Hello termite440,

A mono amp will generally provide more power for subs. And for those Audiobahn's, you'll want something that will provide a minimum of 500-600 watts RMS to each, a least a 1000 watt amp. At the low end, something like the Alpine MRP-M1000 or the Orion HCCA-D2400 will provide 1000-1200 watts. I'd recommend the Alpine. For more power, and another $100, look at the Alpine M2000, or for another $250, the Rockford-Fosgate T1500-1bd.

Hope this helps.

One of the circuits on the "board" may be loose, or poorly soldered. I had a similar issue with My Pioneer unit. I checked them all, added some solder to the loose ones, and it was as good as new. Best of Luck.
