I am getting ready to have a few sound components installed in my late model 04 SuperCrew. This is my second vehicle ever, I always wanted to install in my first (2000 SuperCab), but I just didn't have the money to do so. So I plan in runnig two kicker amps one zx350.4 ( 60w x 4 @ 4ohms) and one zx550.2. (550w x 1 @ 4ohms bridged). I will be intstalling 4 polk db571 speakers (60w @4ohms, 180max) and finally two polk MM2104 DVC 10" subs (300w @ 4ohms 600w peak). Since this is my first BBQ in terms of stereo equipment. Should I get a new battery? Maybe a Optima yellow top? What a about a new high output alternator? I have to say this upgrading cost a lot more than I thought, but I really need to upgrade cause I swaped my 6 disk non audiophile HU for a 6 disk audiophile HU, and now my music sounds like crap because I don't have a sub. My truck has the tow package which I believe comes with the upgraded alternator. I really appreciate the help, thank you all.

 

battery, yes. alternator...not really unless you notice after the battery upgrade that you need it, but the optima's are monsters. they're expensive but a payoff in the long run. make sure you have some good wiring and you'll be happy.

 

With 800 watts just have the correct size wire. And do a Big 3/4.

 

Thanks for the advice. I am going to go with two kicker complete amp intallation kits. I'm not sure whether to go with:

My amp and speaker specs are posted in the first thread. I looked up the optima yellow top on their website and about 5 different matches come up, so I'm not sure which to go with either. Like I said this is my first BBQ in terms of car audio so please bare with me. I just know that if I want some advice from the best, I have to come to this website. Thanks again.
