i'm buying 2 "new" 10" sub's off of my friend 1 is a rockford fosgate RFP3410 and the other on is a rockford fosgate RFD3810!!

now i've been looking online to see the specs of the 2 and what not. and the RFP3410 is an impedance-4 ohms. and the RFP3810 is an impedance-8 ohms.

which is a better ohm to go with? can i still run the 2 in a box off of the same amp?

i'm new to the audio part of the car sceen!
thanks

 

you can not run those two in the same box or off of the same amplifier - well, you could but you don't want to - you need matching subs.

That sub you choose is entirely dependent upon your choice of amplifier...

 

thanks.
my amp is a 2-4 ohm. so i should go with the 4 ohm sub's then?
thanks

 

it depends on what the subs can take u are proble better off going with just one sub anyway in a CRX 2 subs is very much over kill

 

Yes, don't put different subs in the same car, you'll never get it to sound right. You should probably go with the 4, bridge your amp to run at 2 ohms. Check the power ratings first though.

The lower the number (i.e. 2ohm) the more distortion. However, this also allows the amp to run more power to the speaker (less resistance). In a car, you typically can't hear the difference in distortion between an 8 and 4 ohm speaker, or even 2...all that road noise plus with a sub your brains are usually rattling to much to know the difference

So, if you want the loudest, get the lowest impedence your amp will handle. I run my Punch 300 at 2 ohms even though it's only rated down to 4.

 

ok my amp is a 4 channel amp. when bridged it is at 4 ohm stable. so should i go with the 2 8 ohms subs and wire them paralle? or get the 2 4 ohms sub and wire them....???
thanks for the help

Go with the 2x 8ohms in parallel, which gives you 4 ohms. 2x 4 ohm subs in parallel = 2 ohms, and 2x4 ohms in series = 8 ohms.
