Default Need advice

What'* up everyone. It'* been a while since I've started a thread. lol. I was planning on getting 2 Kicker CVR'* *These to be exact* http://www.sonicelectronix.com/item_...al+4+ohm-.html . I know they're nothing special, but it'* just for some bump. lol. My question is, would I need to replace my alternator to accompany these subs? Like I've previously said, I want the minimum amount of dimming in my car. And I also don't want to burn out my alternator. lol. Any help?

Would a battery in the trunk help at all?

It wont really matter what subs ur running... the question is what amp are u going to use? will the amp be bridged? Those are more important questions. Those are nice subs, u wont win any db drags but will be perfect for a daily driver.
More than likely u will not need to upgrade ur charging system.

definitely not looking to compete. I just need some bump for my music. lol. I don't want my alternator burning out or anything. As for the amp, I'm not completely sure as of right now. I'm getting these for Christmas so I still have some time to figure it out. I also don't know if I should have them in a bandpass, sealed or ported box. I'm not doing the install. I good friend of mine is.

Bandpass is useless.. just for looks.
Sealed boxes produce nice tight, good sound quality bass where a ported box will give you boomier bass and will usually produce several more dbs than a sealed box
in my opinion enclosures are the most overlooked aspect of a system. Prefab boxes are easy and convenient but i encourage people to have a box professionally built by a car audio shop to work with your exact sub application. That way u will have the best sound quality and more bass. Its not exactly easy to make ur own box. there are lots of factors.

So in conclusion:
Sealed--- Sound Quality
Ported/Vented--- Higher Output

hope this helps.

If you're going to give them rated power (800 RMS) you should be fine. My amp is 1200w RMS and I have barely any dimming at all with all stock electrical (only upgraded big 3 in 1/0 wire). If you don't care about output as much and want a smaller box, sealed should be fine. I prefer ported because it'* much louder. If you get a properly designed and built ported box it shouldn't be overly boomy. My sub sounds controlled and accurate, and not to mention quite loud. Bandpass boxes can sound good if they are designed and built right, but are difficult to do and not feasible for the average Joe.

If your music dims your headlights, please stay away from my neighborhood. Thanks

If you are worried about your alternator, why not add an additional battery for your audio and charge it up before heading out. I never understood why some add capacitors when a battery makes more sense and does a better job of stabilizing voltage.

Well when u add a second battery ur alt is trying to keep both charged, if u install an isolator then ur system is only running off the batt in the trunk and u can still experience voltage drop.... but dont quote me just yet... gotta check my notes. i reserched this topic a while backbut i got a chitty memory.
So doing a big 3 upgrade and larger alt does more than adding a second batt or a cap
