Default What amp to use? HELP!

I have 2 Kicker 15"s in a truck box, but I have no amp. I know that i need a two channel amp so that I can bridge it to hook up to the box. All help is appreciated, and thanks in advance

What is the power handling of the subs?

10watt 1000watt?

Ideally it would be good to have an amp that can provide enough power to match the RMS wattage of your subs.

Also, it would help to know if they are dual voice coil, or single. And if they are 2 ohm or 4 ohm. You can almost double your power output by your amp by wiring 2: 4 ohm subs to a mono amp in parallel.
I just got my new kicker in the mail, and it has the ohm rating and rms value on the back of the sub.

O, and I would love to see some video or pictures, 2 15" kickers must be insane!

Ok, I took one out of the box, and it is 4ohm, DVC
I looked up these subs online, and it says they are 2000w max, 1000 rms

btw, i have had these in my truck before, but i only had a 1800w interfire amp, but they still pounded like hell.

and i am uploading pics now.

For futrue reference, this is where I am getting this information: Subwoofer Wiring Diagrams

You will either want this setup w/ a two channel amp: http://akamaipix.crutchfield.com/ca/..._4-ohm_2ch.jpg 2ohm load each

or this w/ a mono amp: http://akamaipix.crutchfield.com/ca/...4-ohm_mono.jpg 4 ohm load total

So, now you can search for an amp that will provide 1000w rms to each subwoofer. IE: a 2000w rms mono, or a 1000w rms each 2 channel.

Ignore peak values, the numbers are impressive, but do not provide a good point of reference.

Bottom line:
When you are searching you will want to look for a mono amp that can provide 2000w rms @ 4 ohms, or a two channel amp that will provide 1000W X 2 @2 ohm.

Here are the sites I have looked at in the past. I have only ever ordered from sonicelectronix, but I am sure others can vouch for the other two.
Car Audio Stereo - Car Subwoofers - Car Amplifiers and Speakers
Crutchfield: LCD TV, Car Stereo, Home Theater, Speakers, Plasma TV
Woofersetc.com the online car audio super store, the largest selection at the lowest prices!

Edit to add: Are you sure those are the comp vx? It should be labeled. I had always thought that the silver cone ment that it was in the vt/cvt series, and that the vx had a darker cone.

Ok I understand that I need an amp that is gonna give the subs 1000 rms each, but what is the difference between running a 2ohm load and a 4ohm load? Isn't 2 more unstable? And I'm pretty sure the cvr's, but ill check when I get home I'm at work now


Thanks for all your help man I really appreciate it

and i checked the subs, they are comp vrs. And i was thinking about getting an amp that was maybe 750-800 rms per channel, because the ones that are 1000rms per channel are crazy expensive

Comp vrs are rated at 500w rms while comp vx's are rated 1000w rms.

The ohm rating is just the resistence presented by the subs. Generaly, amps can do 1.5-2 times more power at 2 ohms than 4ohms, so you can buy a cheaper amp.

Also forgot to mention. Here are the brands that through much research, I think are good brands. Although, I have only used pioneer amps myself.
-Kicker
-alpine
-kenwood
-mtx
-pheonix gold
-hifonics (can be a bit overated)
-JL
-Memphis
-boston

Often times the cheaper brands like hitron, boss, jensen, ect. will be rated at a much higher output than they actually can do. Also, they can distort the music badly.
Ofcourse, there are exceptions, some will say that the brands I listed are crap, and that they love their jensen, or w/e. Just my opinion.

ok, so you're saying that the subs i have are only 500 rms and 1000 max?

Higher Ohm load is more stable, but at the cost of volume. As far as wiring them up with a 2-channel at 2-ohm, BE SURE the amp is 2 ohm stable. I have fried amps before by not double checking when the guy at the store said it was. Your better bet will probably be the mono block amp, and wiring the subs to 4 ohm, better sound quality, and less heat. Also, probably cheaper.
