Ok so quick update... I am on deployment and am buying upgrades for my truck and won’t be installed until this summer when I get back to the states... so I need your guys

I just got 2 10" Kenwood eXcelon KFC-XW1000F Shallow Subwoofers with a downfiring Fox box (which I am pretty excited about since I had a single 10 sub before not sure what amp was for that.) I heard good reviews on the subs and the box separately and well few bad one just because these subs got over powered by the amp. I need to find out what would be a good amp that won’t blow the sub but will give it enough power.

I am excited to get back to the states!!!!

Here are the specs for the sub:

• Max Power: 1200W
• Super Linear Spider
• 10" Woofer Carbon-fiberglass Honeycomb
• Alum. Diecast Basket
• Heat Transfer system
• Power range: 50-250 watts RMS
• Frequency response: 35-800 Hz
• Sensitivity: 90 dB

 

You left out what ohm load subs your going with. So once you figured that out id go with an amp that can either do 200 watts rms per channel or 400 watts rms on a single channel to drive the two subs at the right ohm load of course.

 

for some odd reason that helped a lot... no I’m understanding the whole watts to ohms...

From reading the manual on the specs of the speakers they are 4 ohms speakers. Now if I go with a amp that can do 500w in mono at 4 ohms, I should still be safe as long as I don’t go below/above my frequency response right?

thanks for the help!!!

 

If they are single 4 ohm's then you need an amp that can do right around 400watts at 2ohms. If they are dual 4ohm's then you need an amp that can do the 400 watts at 4ohms.

The ohm loads are in a easy way to put a way to wire your subs to the amp to get the most power out of it.

I however would not try to put full rms power to those kenwoods.. I would stick to about 200 per sub not 250.

Going above your freqeuncy response won't hurt the speaker as bad as going below, it'll just have very little output if any. Going below however can cause all sorts of problems and blow them in no time at all.

But that's why amps have filter's on them so you can set the low pass at 35Hz (no signal to the subs under that) and high pass to around 60-70Hz (no signal to subs above that).

But the main way to blow them is trying to put too much power to those subs, kenwood usually only makes good head units. Their subs and amps generally are over-rated. The subs can and will perform good for their price range you just have to be a little more careful with them.

I however would definitely not recommend getting a kenwood amp.

 

How would i know if they are dual 4ohms or single...? right now i know i have a alpine for my single but like i stated above i am deployment and cant get to it.

what brand would you recommend?

once again thank you for the help

 

It should say in the manual or if you have a link to them online it'll tell you, or if you have them on hand you can look at the back and if it has two sets of terminals it's a dual voice coil, one set of terminals is single voice coil.

Good brands would be alpine, kicker, audioque, Rockford, mb quart, and theres more, that's just all I can think of off the top of my head ha.

ok well i think i might just stick with alpine if my current amp can support them...

gosh i hate this slow internet!!! ships suck fyi!

 

Yea they're single voice coil so you can wire them in parallel to get a final 2ohm load.

 

So final outcome should be something like this?

mono amp at 2 ohm 400W rms x 2???

or

4/3/2 brigeded 4 ohm 400w rms

 

so i would run something like this for a 2 ohm 400w x2

 

with something like this as well?

Pioneer GM-D7500M
Mono car amplifier — 400 watts RMS x 1 at 2 ohms


or

 

i wouldn't use pioneer stuff, or sony stuff either.

 

Agreed. Would surely do the 2Ohm load to a mono amp(postivie to postivie, neg to neg). Preferably some sort of class D or BD with a nominal power rating of 400-500 at 2Ohm load. Do you have an aftermarket HU?

My suggestion would be

If the price is to steep look at the refurbed one's. JL, Rockford, and Alpine make decent mono amps. Always check for CEA compliant though.

I tend to go with Rockford for SQ and performance, hard to beat for the price. The one suggested has a 24db/Octave, so the slope can be tweaked to be even across the board.

 

Good amp^. But most expensive place of the internet to order your stuff from.

 

Very true, but when you incorporate the 60 day money back guarantee, and two year warranty. Its very enticing, especially with high end audio stuff.
