In my 2006 scion tc, I've already got a JL Audio w3ve 10" sub with a JL Audio G2250 amp and am looking into upgrading my factory speakers in the car. Would I have to buy another amp if I did this or would my G2250 amp be enough? I don't understand all this peak power, RMS, wattage, etc. stuff so someone please explain this to me. Also, if I don't need to get a new amp, whats the highest power (or wattage or whatever) speakers could I get?
I appreciate your comments
G2250 is a 2-channel amp 80Wx2@4-ohms or 250Wx1@4-ohms bridged. Essentially, you could use it to power your sub OR your new speakers, but really not both.
You could use the head unit without an amp to power the new speakers, but an amp will sound better - do you have the factory or an aftermarket HU?, btw.
RMS power - what you should be concerned with.
peak power - marketing sales ploy.
(That's over-simplified, but it's good enough).
Just like subs - ideally you want your amp RMS to be at least 70% of your speaker RMS.
If you are running them off the head unit only - you will get the best sound from 30-45W RMS or so speakers. However, they doesn't mean you can't run 90W speakers off the head unit if you plan to amp them later - they just won't sound as good as they could now.
Hope This Helps!!!
