Car Stereos
Hey guys, any one know anything about car stereos and amplifiers?
Heres the thing. My niece has a 2007 corolla with a horrible stock system.
So, for Christmas I got her a Kenwood double DIN head unit so she has USB, Blutooth and hands free calling from it with her Iphone. Shes wanted something like this a long time.
But I seen no point doing the head unit when her speakers are so bad. So I decided to upgrade them as well, and add a proper amplifier to power them properly.
The amp is a Rockford Prime 250x4 (40W RMSx4)
Door speakers are Rockford Primes 6.75" at 4ohm. Doors are shallow mount so very limited as to what will work in there.
The rear deck Speakers are Infinity 6x9s.
After looking closer, its odd the way its worded. The Infinitys are technically 2 ohm, but by using the factory wiring etc.. it makes a true 4 ohm speaker, or the amp sees them as 4ohm.
But I will not be using the thin factory speaker wire, and running new 16g wire directly from the speakers to the amp for them, so lets assume they come out as being seen as 2ohm.
So my question is, will the amp have issues with a 4ohm load on the front channels, and a 2 Ohm load on the rear channels?
For what its worth, Rockfords says the amp will run 2ohm no issue.
More specifically they say: 40Wx4 RMS @ 4 Ohm 60Wx4 RMS @ 2Ohm or 125W RMS x2 Bridged @4Ohm
But unlear on the 4ohm front 2 Ohm rear question.
