Re: Attempting to install a sound system for the 1st time!!!
All of that equipment sounds awful.
No, you'll never ever need a capacitor. And anyone that tells you that you do need one, has no idea wtf they are talking about.
I'm happy to see you're going by RMS ratings at least. I wouldn't go anywhere near the Kenwood subs or amps though.
If you're just looking to buy a cheap subwoofer box online or from a store, you'll have to buy a sealed box. And in that instance, I'd get either one 12" or 15" of these subs: Sub Woofers - Sundown Audio - E Series - SSA STORE
OR, if you want to get the most output of your sub and decided to get a ported box, I'd recommend the 10" woofer. Keep in mind that if you do get a ported box, you'll have to have one custom made, which is a service many members and vendors on here can fulfill, some even local to you. With a ported box, it must be custom made; why, you ask? Because ported boxes require a more intricate design that should be based around the woofer being used, the vehicle it's being used in, and the user's listening tastes. Any store-bought ported (or vented) box is not designed with any of these in mind, and is tuned too high, and sounds like total crap, and does not provide enough internal volume for a woofer to perform optimally.
If you do go with any of those subs, get the Dual 2 ohm option if you buy 1 sub (which will be plenty of output). Or if you want to splurge and get 2 subs, you'll need to get the Dual 4 ohm option. That will be the case with ANY woofer you buy. Regardless of which woofer you buy in the future, if you only buy one of them, it needs to be Dual 2 ohm. If you buy a pair of them, they need to be Dual 4 ohm. (This is assuming the amplifier you purchase, makes it's most power at 1ohm. Some of them make their ideal power at 2 ohm, in which case you'd switch the above-stated rules of thumb)
As for an amplifier to pair with one of those subwoofers, are you open to buying used, or must you waste more money buying new?
As for amp kits... Don't even think Boss again. As for ANYTHING car audio, don't ever think Boss again.
For an amp kit, something like this would be best for your current situation: http://www.knukonceptz.com/productDe...?prodID=KCA-K4
Or this one: http://www.audiotechnix.com/componen...etail?Itemid=0
The 2nd one is available through the vendor on here, and he is a really good guy. Both kits will do exactly what you need for this power stage.
