I have a Vaxhall Corsa and want to change and upgrade my current speakers. they are only 5.25 inch speakers mounted in the doors, along with i think 2 tweeters where the door handle is.
I was also thinking about adding 2 x 400W subs along with 2 Amps, Powering them seperate, or A single Amp powering both, if possible. Also want to see if i can get some 6x9 speakers in there as well.
How would i get the sound from my head unit it to the speakers? and also how can i power this with out using my car battery
you should buy a Built- in battery speaker.
