Thanks.
Yes. Thank you so much buddy. It was fun but now I want more power. Do you happen to know if there is such thing as a perf board with bigger holes to fit bigger pins, and where to buy them for a good price?
I did it!
So after a couple months of waiting for parts and juggling my schedule I was able to make a TDA7377 amp. It was a pain to build on a perf board. It sounds pretty good but Audioguru you were right. After about 14 watts it sounds it loses its clean crisp sound. Even when using an 18v...
Thank you buddy. When you say film you mean Polyester Film? Audio Coupling is the cap that you connect the input to right. After so many questions will u guys get annoyed? :(
Nah not this one. This Subwoofer is from a Sony Home Stereo. lol. But I got a good question. I use regular Carbon Film 1/4w 5% resistors and regular Monolithic Ceramic 50v and Electrolytic Capacitors 16v. Do you guys recommend using Metal Film 1/4w 1% resistors instead? And instead of Ceramic...
Quick question. I have a cheap 6ohm subwoofer. If I parallel this 6ohm sub with one of the 4ohm speakers. What ohm do I end up with? Since crutch said that two 4ohm speakers in parallel become 2ohm, what does 6ohm and 4ohm become?
Oh wow! I found a chip called TDA7377 and according to this chip its stereo 2x30W Dual/Quad amp. I will order this one too. I shall return to see how the chips work out.
Thanks audioguru, sorry for late reply, my internet went down for a whole day, but yes my speakers are 4ohm 6inch side door speakers. So I think the TDA2005 will do just fine. I also have a 6ohm Cheap Subwoofer. Just don't know how to apply that to my circuit. lol.
So to power my car speakers what do you recommend? TDA7256 or TDA7240 or TDA2005? Of course I will buy one chip for each speaker. But I want the most power and best sound for the price. :D
I agree. But I pulled up the Datasheet of the chip you recommended and saw that they grounded Pin 5 and Pin 7 so that confused me again. But I guess thats not called grounding when you put a resistor and cap towards ground. I still have alot to learn and I really appreciate you guys taking time...
Oh my gosh! Audioguru you are awesome man. Thanks alot buddy. I feel like a total noob. But yes that all makes sense. I am sadly using the wrong chip for what I want to do. This forum is the best. If you guys have any more simple troubleshooting tips for us noobs, I know I will run into them...
Wow! I will order one of those ASAP. :D But as for the floating, if the negative speaker terminal doesn't go to ground then where does it go? lol sorry I am still new to this.
Thank you very much Nigel. So that explains why my amp cannot push my 6" Car Side Door Speaker. It sounds so low. And when I crank it higher it distorts very easily. :(
