Hey guys, I'm new here to Club Polk, but thought ya'll might offer me some advice nonetheless! Now, to begin with, I am very new to the car audio stuff, so ya'll please tell me if I am making a mistake or bad choice in anything I am doing! Thanks in advance for your time and advice!
Ok, so I have an old boat that I want to make some improvements on for wakeboarding, so I am starting with the stereo. I currently have an old AM/FM radio w/ 4 speakers, yet only 1 speaker works. So, here is what I am planning. Keep in mind I am just a student living entirely on student loans, so I want to make this as affordable as possible!
Items I've already purchased:
2 - Polk db650's to replace my old 6.5" speakers in the rear of the boat. Got these on closeout for $56 shipped, so I'm pleased about that!
2 - Polk db690's to replace some old "box-like" speakers under the driver and passenger side dashes, where your feet go. I really don't want to be cutting into the boat much, so I thought about getting some 6 x 9 enclosures for them and mounting them up under there very near where the current speakers are mounted. That sound ok?
Items I am still debating about:
A head unit!
Possibly a subwoofer -- in the future, if ever!
Ok, here is where I'd like to have ya'lls advice!
Question #1 - the head unit!
I am trying to keep a tight budget, so I can't go all out. My first question is this...do I need to be concerned about the # of pre-amp outlets included on the head unit I purchase? Someone suggested to me to find one with at least 2 pre-amp outputs. Is that the case? I plan on running only a single 4-channel amp initially, but perhaps may add one later to run a sub, or maybe I'll buy a 5-channel amp now?? Anyways, how many pre-amp outlets should I look for?
Question #2 - the amp!
Ok, so the db650's will handle 60w RMS, and the db690's will handle 100w RMS. I figured I would get a 4-channel amp to run these. (or perhaps a 5-channel if I feel I'll purchase a sub one day) What power rating should I get for the amp?? Should I get one that runs 60w x 4 @ 4ohms, or maybe 75w x 4 @ 4ohms? Is it ok to go over the RMS rating of the speakers, or should I stick with 60w RMS or less. Basically, tell me what RMS power from the amp I should be looking for! What do ya'll think? (Oh, by the way, I opted for the db690's over 4-db650's because I just don't know if I'll ever get a subwoofer due to lack of space on the boat, so i thought the 6x9's would give me more bass) What is your recommendation on the amp! Here are links to some of the amps I was considering...what do ya'll think??
A friend recommended this Phoenix Gold amp to me.
Customer service at Crutchfield recommended this amp for the setup...mostly because they sold it! Found it here on ebay much cheaper.
I've heard good things about HiFonics amps, and I found the two listed below, both 4-channel amps. What do ya'll think about them?
One last one, I was also recommended Orion, and I found this Orion Cobalt on eBay that looked interesting (my boat is a Cobalt, too!)
Guys, thanks so much in advance for any help you might offer. I just don't know what to look for yet! I know I included lots of links, and if you take the time to go through them, I appreciate it. Also, if you know of an amp that would work better for me than any of those I linked, please say so! Thanks again, I appreciate ya'll.
