2nd gen double cab

alright guys today i wana wire up an amp to my speakers and also want to add new speakers, what size are the stock ones? can i just install new ones without the adapters? also any tips on wiring up a capacitor?

 

Front are 6x9 rear are 6.5. What do you need a capacitor for?

 

i already have 3 alpine type rs and my lights dim to the beat of the sound when at a stop sign, so i shouldnt need those special spacers for new speakers?

 

I have them for the front and rear

 

wouldnt it hit the windows without spacers?

 

capacitors SUCK. they work, but barely. if you need something like that bad enough, get a secondary optima yellow top (deep cycle)

i ran optima in my old car because capacitor sucked. i had 2 memphis pr-12's and memphis amp

(and dont laught at my daewoo haha, i had the loudest 2 speaker subwoofer system in my county!!)
