Alpine KTP-445A Power Pack / Polk Audio db651 / Polk Audio db5251
Crutchfield Customer Review (What's this?)
Ordered this Amp along with Polk Audio db5251 Component Speakers for the Fronts and Polk Audio db651 to match my Alpine 143bt Head Unit for the Rear of my 2003 Toyota Sequoia, showroom condition w/ 45,000 miles. The installation was a bear I had read. I am a perfectionist and spent 4 days running all new wire and bypassing the OEM Loom. It was necessary to remove all door panels and center console, door sills etc along with a very creative Front Speaker installation. Once completed the results were fantastic. Rarely had I heard the OEM Rears and very non responsive OEM Tweeters. The addition of the Alpine Amp was smooth as glass once the interior as well as the Console were removed. The combination of all was dramatic. The Polks sound great, the tweeters were very easy to mount in the Factory position and And the Rears were a piece of cake to install. The front Bass Speakers took quite some time, thought and customization. The outcome was incredible. The Polks along with the Amp and HU brought out the best of everything be it BT, Thumb Drive etc. I am now hearing the finer highs and the Bass after minor HU adjustments made the Interior sound like my home theater. A great pairing of products.
Pros: Excellent sound quality, easy install ( excluding the modifications to the OEM speaker brackets ). Extremely Happy with my purchase from Crutchfield which is the norm. If you haven't dealt with Crutchfield before do yourself a favor and go for it. Superior customer service and support.
Cons: Tough installation only due to OEM brackets.....other than that Plug and Play and Enjoy.
