Thanks for the advice. But I am going to need about 100wpc to drive the speakers properly. Snoman, I found a class d Zapco amp with small deminsions. https://www.amazon.com/gp/aw/d/B00EC...mFL&ref=plSrch

Sno, do you think I will need a noise filter with the Zapco ST-4D amp? I know some amps need one due to the FARK and hi level inputs. Also I am looking into those Kappa 6x9s that you recommended. As for the front component tweeters (Infinity Kappa 60.11CS), do you or anyone else know how much modification may be needed to mount properly? I know that they physically fit. Thanks!

Did you look at the Zapco ST104D BT amp? It does like 92 WPC and fits in the palm of your hand.

There is zero modification required, the speakers drop straight into the OEM housing. I will personally rewire the tweeters, but it is not advised as you can easily damage them by frying the voice coils through heat. If your good with solder, go for it though it's not necessary as the OEM wiring "will work".

I have not. But, after reading your reply I looked it up. Nice size amp and power. I cannot find anything about it being 2ohm stable.

That is a class A/B amplifier (not D) Usable SNR is less than 80% (should never use or install anything less than 100dB THD @ 1w@1m (often times referred to as A-weighted). Rated power is based off 14.4V (not 12). <--- This is the big one. This is common practice from companies like Kenwood/Sony/JVC and lower quality brands to purposefully inflate power output nearly 40%. Kenwood does not "over build" their amplifiers like "class II" manufactures do (ex. JL, Alpine, RF, etc). I'm basically saying Kenwood is lying through their teeth about "usable output", it's pure snake oil. While Class II amps are typically rated at 13.8v, nearly every single one is 'over built', producing rated output at 12.5v. Entry level quality is barely above OEM, in fact it is so close in build quality that I recommend people spend their money elsewhere. Class II amplifiers are double the quality and usually come with lower cost per usable watt, increased dampening, better line noise cancellation features and more. If you're going to purchase some parts and build something, most people want to get the best return of value they can for their hard earned dollar instead of lighting it on fire with a torch and throwing it away.

It's a class D amp. And a good one. The amp has been bench tested on YouTube and you can look up the facts before spewing non sense. |

Per Kenwood user manual; SNR A-weighted, CES-2006 compliance standards: 80db Rated A/B Power output into 2 ohms @ 14.4v = 75w. Converted to 12.5v per the laws of physics (Ohm's law): 50w. I won't even begin to get into the lack of quality build components, power rails, lack of balanced separated input stages and more. Street price: $100-125 If anyone is seriously going entry level, the current leader in this arena is the PPI 900.4 and PPI 900.5 from Precision Power. Street prices of $165 and $190 respectively. The 900.4 was quality tested by SonicElectronix, along with massive public feedback for being the best entry level amp on the market. There is a another independent review from PASMAG HERE as well. PPI 900.4: SNR A-weighted, CES-2006 compliance standards: 82db Rated Power output into 2 ohms @ 14.4v = 225w. Rated power into 2 ohms @ 12.0v: 150w. Build quality: has a separated (built-in) pre-amp stage and dedicated output stage. Triple protection circuitry protecting amp and speakers and more Street price: $150-165 Crutchfield actually wrote an excellent article about the difference between entry level amplifiers and quality -> HERE

The entry level market is the only singular audience Kenwood has ever been successful marketing to for their amplifiers, ever. They are cheap entry level reliable no-nonsense quality you can trust. Kenwood makes some nice head units, but I will never certify one of their amps (and never have). They simply have never been able to meet the quality build standards set forth by available manufactures elsewhere for entry level amplifiers. Do your research, expand your mind
Anecdotes generally don't cut it on the internet. Do you have ANY sources for your claims? If not I don't have anything else to say. |

Was planning on Infinity components. Got a few recommendations from a guy around here for amp brands. Researched. Ordered Zapco. Thanks for the info sno. Good lookin out.

I've already proven above there are better within the suggested entry level class range through third party links and price analysis. I also usually try to provide actual links to relevant information if possible so others can make their own decisions based on reliable information, instead of just the suppositions proposed by most. I even went to far as to provide you research material to help you understand why entry level electronics are so cheap. If all someone has ever heard their entire life was an MP3 through an OEM system, entry level equipment will make you wet your pants it will sound so good. If you had ever heard SACD on Martin Logans, we wouldn't be having this discussion. I have over 30 years history within the field and I believe even a bit respected on the forums here for providing reliable proven information. Most welcome!
