Guys I have done a lot of research and come to the conclusion JL Audio 10W3v3-4 W3v3 Subwoofers. I can do a fair install and use my brother as a back-up as he works on electrical devices but I would be stretching it thin to say we know a lot about the actual design of a system. This takes some knowledge. So far I am putting some Alpine S-types in my doors with a four channel amp and the subs under the rear seat. My question is: What amp would you recommend for these subs and door speakers? I kinda don't like stealing information from a salesperson and then not buying his product so I would like some free info if you have any. Its easy for me to get lost in the Ohms and amps. Yes, some will reply.. you shouldn't be installing then but I don't believe thats the case with a little learned knowledge being passed on. THanks in advance for the help.
