Hey guys. Been a while... So, I decided to upgrade my head unit to an Alpine head unit. I have it installed, it looks great, but it doesn't sound great. I used a harness that worked. I don't have the tweeters bass blocked though. What I am thinking about doing is ripping all the factory speakers and amps out and starting from scratch. What would I need? I have an RCA cable and an 1100w mono amp pushing my JL Audio subs, but I have the gain turned super low to keep from drowning out the other speakers. I was thinking, even though the Alpine unit is pushing like 35w channel, I would go through new amps with crossover built in. Run all new speaker wire to all speakers and route them to the trunk where this amp would live. Any suggestions? Also, what all speaker sizes would I need? Thanks in advance!
