I just traded my old sub in for a Rockford Fosgate RFZ 3410 10" sub. It's 150 rms and 400 watt peak. I have only 3-4 days left to return my old amp to the store due to 30 day refund.... I am currently using the Kenwood 629S which is only 150 watt bridged... I was thinking of putting in more power to the subwoofer. I don't know whether to choose from the Rockford 200S or 300S amp... i need some expert advice on which amp i should use for the best output from the 10" Rockford sub....

 

You can never have too much.....you can always turn the gain down

 

exactly............. i made that mistake with my subs.........too little power

now i have to go waste my money on 4pumped's shitty chromed idmax's and a big amp j/k (thanks 4pumped!)

the moral of my tale is the more wattage, the better

 

from what you two have said.... should i stick to the 150W amp right now to power the Rockford or get a 200 or 300W to power it???

 

Keep the new sub and get the new amp.....if a sub is 150 rms 400 peak and you get a 300 watt amp......you can turn down the gain on the amp to get a CLEAN 150 watts......with room for improvement. Who knows, you may get a 12" or 2 10"s later on.

 

cool.... thanks man... i also found out that the Rockford 200M amp is a mono amp. It give 200@2ohms and 100@4ohms... so in conculsion.. does it mean that its only giving out 100W to the sub since the sub is impedence 4ohms??

whereas the Rockford 200S is a 2 chnl amp and bridgeable and gives 200@4ohms...

Which one should i go for? they both can be said the same having a max of 400W but one is mono and one is 2/1 chnl.

 

the rockford amp would push this speaker just find..... just bridge it mono and it will push 200w to that speaker...

 

alright cool thanks man
