Thanks guys, I'm glad you found it useful.....I've been meaning to do a proper write-up on it for a loooooong time now.

bdog_v- I'm using the stock tweeters in my setup. They sounded great to me, so I stuck with what I had there. Also the 4" have little dome tweeters in the middle, so between the twp they REALLY produce some nice crystally highs. About the part numbers....I have no idea what the numbers are, but the 8" are Kicker Resolution RMB-8 midbass speakers, and the 4" are just from the Kicker Resolution series. Both sound very very clean.

On to your questions about the "full-range" and "bass-blockers". With my setup I used the headunit's front speaker outputs which wasn't being used to power the stock speakers (the wiring harness I used simply uses a set of RCA's to send signal to the two factory amps in the 8-speaker sound configuration....this left me with both the front and rear outputs free at my disposal). Those front outputs are Full-Range outputs, which on most headunits give you a perfect output designed for the use of a midrange component.

Now if you use tweeters or woofers, you will need to specify what frequencies are sent through that amplified signal from the amp. This is so that you don't feed a speaker a frequency that it wasn't designed to handle for saftey purposes and for the most accurate sound possible. Most tweeters will come with a set of crossovers, which are usually what they call a low-pass filter that will prevent low frequency signals from making their way to the speaker. Likewise, a subwoofer will need to use a high-pass filter to ensure that ONLY low frequency signal is fed to the woofer. This is easily accomplished just by selecting ether low pass, high pass, or full range on just about any aftermarker power amp. Naturally a subwoofer will require the power of an aftermarket amp while a set of tweeters requires much less.....usually better off just wiring a set up in series with a set of your mid-range speakers and then before the wire leads connect to the tweeters use the crossover that i talked about above.


So lets review here. This is how I wired my setup--

Headunit was wired using the Metra harness that I've linked before for the Toyota Avalon, called an amplifier integration harness. Easily sourced through a Google search.

FL, FR, RL, and RR signal was connected via RCA inputs on the harness. This leaves all four speaker leads open on your aftermarket headunit.

4" midrange in door- Connected to the available front outputs from the headunit- no crossover needed.

8" mid-bass wired to an aftermarket 2 channel amp, and used the built-in crossover thats on almost every aftermarket amp made and selected a High-pass filter setting = no highs to disrupt the signal.

I also have the 10" in the trunk to top it all off, using another amp with about the same crossover settings as the 8"s.



Again I hope this helps to clarify. Let me know if you have any more questions, I'm here to help.
