I Need a Critique of my Planned System

it sounds ok, but you may no like the band pass box. You may like them, and if you do don't let me talk you out of it. I don't like them they can be real loud, but to me they just don't sound that great. I like a sealed box. I think they just play more tones than band pass. look up band pass boxes on this site and read all about them then make up your mind. As for the batt yes there is a "music car battery" stinger makes a good batt, lighting audio does and batcap makes a awsome batt too. be prepaired to spend a few bucks on one. you will want a good alt too. 150amp should work good for you. good luck!Big Dave

also optima yellow tops, although ive been told they arent as good as they used to be, but you will definately want to upgrade your alt. with your sound system.Quad L Handyman services

I hope you're ready for some critisism (constructive that is) First... When you're dealing with subs, you want to work with the RMS rating, not the Peak rating. The RFD2212 Punch HX2's are 4ohm DVC's rated 500RMS 1000Peak. These are good subs (I'm running 2 RFD2112's, the 2ohm model). But if you design your system based on the Peak rating, you'll blow your subs in a heartbeat. Second... When you're dealing with amps, you want to again look at the RMS output, not the Peak output. You'll never hit the "max" power of an amp. Companies run the amps until they melt and at ungodly input voltage and amperage (usually based on a 14.4 volt system, not a standard 12 volt system). The "max" rating comes right before the amp blows up. So by no means should you expect "2,400 watts" from that RF Punch 801S. Third... Don't get me wrong, I'm a fan of RF subs and amps. But you improperly matched your subs to an inferior amp. The Punch 801S is a 2-Channel Class AB amp rated 400x2@2ohms stereo and 800x1@4ohms mono/bridged. Since your subs are 500 watts RMS, and the most you could send them with your amp is 400 watts, you'll be underpowering them. That means you'll probably end up cranking the gains to get more output (which is severly incorrect) and cause the amp to clip and fry damaging the amp and possibly your subs. You really need a Class-D Mono amp rated 1000x1@1ohm (like the JBL BP1200.1 which is 1200x1@1ohm) or a different Class-AB 2-channel amp rated 500x2@2ohms stereo or 1000x1@4ohms mono/bridged. You should really try to use a Class D Mono amp for subs, you get more bang for the buck than you would using a Class AB Multi-channel amp that is designed to run internal speakers. Finally... I'm not a fan of bandpass boxes by any means. Those subs will perform better out of a small sealed enclosure or a properly tuned ported enclosure. I've blown bandpass boxes apart with less wattage then you'll be running. IMO, they're junk. I've run systems in my old '90 Probe and '97 Probe and the best sounding systems came from small sealed enclosures. And yes, I ran sealed, ported, and bandpass enclosures in both vehicles. I'm not trying to blast you dude, but you asked for a critique Squirrel

I second wvsquirel on his feelings toward bandpass boxes, yeah they look cool but so many notes don't get reproduced what ends up happening is your music sounds like crap. Look at a sealed box or a properly tuned ported box and definetly think about getting it built specifically for the subs that you end up buying as this will always give you better results. Also look at rms ratings and not "max" ratings when matching amps to subs or vice versa.

I agree 100% with wvsquirrel and will add this:  Are you using the Kenwood speakers as your mains because you really, really like their sound?  I ask because I personally feel they suck quite badly.  There are much better sounding mains than Kenwoods out there... but hey, if you like the way they sound, then go for it.  Just be VERY careful not to overpower them (RMS rating) because they blow like 1/2 amp fuses....

Oh yeah you guys, just cus I'm not around to post much right now (did more business in two days than the entire month of January) doesn't mean I won't agree with what squirrel and Dyohn have already mentioned. Do a little more research into your equipment again and the end result will probably be much better for your investment.Top Secret, I can tell you but then my wife will kill me.
