50x4 to 75x4 will be plenty.

 

[fatnlowtahoe504]

memphis, alpine, JL, boston, focal, and mb quart all make good highs amps, if you want to stick with the same company just go with the alpine and you will be fine and get the ones with the power rating as groundscr8pr said

 

[Tahoewhat]

thanks guys, im still looking. but this does help in my search...
thanks groundscr8pr for the ratings...

I'd get some over head, 85x4 to 125x4

finding an amp that does a true 125x4 will be very exspensive and most speakers arnt goung to handle that kind of power. you also need to remember mid and high speakers are very efficiant and need very little power to play loud. i always say the more power the better . but you also need to be carfull you arnt cooking vioce coils everytime you turn around.

125x4 isn't that far to find, many manu's are making those. rather see true clean power, that someone adding more gain to compensate, for lack of. that will burn coil faster than a clean signal.

i agree.. but ... 99.99999% of blown speakers are blown with too little power not too much.. and unless youre running a 90db or higher efficiency.. then efficient yes.. i wouldnt exactly call them "very" efficient..

Not knocking YOU its just a number HE should look into since most people totally neglect this super important number...

I like over rated amps with the gain turned down personally.. 125w on a 100w speaker is ideal imo

 

[blueflamed03]

agree Mob, but clarify wording a little, they blow with too much distortion, aka clipping, not too little of power. People try to compensate with adding more gain, when power is lacking.

aaaannnnndddddd.. they compensate because offffffff.....?



Cough cough.. too little power cough cough...

lol

 

[blueflamed03]

too little power is the effect, maxing gain is the cause

it's not lack of power that killed them, it was the clipping.

I just don't want people later to read this and assume "I have mids that say 50 RMS 150 max, I may blow them with 45 watts.."

 

[MOBmentality]

fixed

too little power is the CAUSE, maxing gain is the EFFECT Blowing your speakers is the RESULT

it's not lack of power that killed them, it was the clipping. From people trying to pull more clean power out of the speaker than they were putting in.

OK, you guys kinda lost me. but like blueflame said, i want it to sound good and clean. No distortion, but don't want to blow them either. Someone recommended me the fosgate r300-4. i was looking at more of the p400-4
50W x 4 @ 4-Ohms RMS
100W x 4 @ 2-Ohms RMS
200W x 2 @ 4-Ohms bridged RMS
WOuld that be fine or to much overload and blow them?
Here is the specs on the alpines i have
Handles up to 240W peak power (80W RMS)
# Frequency response: 70Hz - 22kHz
# Sensitivity: 88dB/W (1m)
# Impedance: 4 ohms
Does that help any?
Just looking for a good clean amp that will make them sound good. I have some junk i can throw in there, but tired of hooking up amp, taking out, putting in... just want to do it right the first time. ONly change for the better..

 

[MOBmentality]

400.4 and just keep your amp gain in check

that is a great amp. make sure to go to jl audio.com and check out the gain setting tutorial under the support section. set your gains correctly and you will be a happy camper.

btw.. if youre gonna run that amp true.. its 50w per channel.. at 4ohms... not 100w ... if you wanna get 100w per channel true stereo youre gonna have to run it like a 2/ch
(lf/lr on one channel rf/rr on the other) ...

IMHO that amp is fine

pmed you. Which is better? running it true or like you said 2ch.?

Thanks for that info, i was wondering if there was a place online somewhere.

IMHO that amp is fine

Ok i will try it, but can any of you recommend another one that would be good for this.

thanks for answering guys, just trying to learn all this the correct way instead of just plugging things in and not really understanding it..

Make sure you seal your box on your subs and then you can run any decent amp at least 400 watts and up

thanks, i got the box built already for my DD subs. Now im trying to find a amp for the alpines (doors) and a good amp to power the dd subs.

Anyone got reccomendations for a amp to power 2 dd 1510 10" subs?
