[QUOTE="Macksamillion, post: 8708894, member: 679704"] I don't know if this is crazy, or maybe people do it all the time. You guys can tell me. I have a Taramps DS4404. It's a 4-channel amp, rated at something like 65 watts per channel RMS. I want to run a pair of 6.5" mids on two channels, and FOUR tweeters on the remaining two channels (two tweeters per channel). It gets interesting because I want to have all four channels running at a 4-ohm load. That means I need to have 8-ohm tweeters, right? Simple enough. The problem comes in when trying to find 8-ohm tweeters that LOOK LIKE ones you'd have in a car. All the 8-ohm tweeters look like the typical circular or horn cabinet-mount tweeters you'd find in a home audio speaker enclosure. I very much want to have that look of a recessed swivel car audio tweeter. Here's the question. is it acceptable (or practical) to wire a 4-ohm resistor in series with the voicecoil of a tweeter, in order to increase its impedance to 8-ohm? That way, I could wire each pair in parallel to achieve my desired 4-ohm load. Will this work? If it does work, is there a downside? Will it throw off something in the amplifier? Will it affect the sound quality of the tweeter? [/QUOTE]
