Yes LM1875.
If I have already tda2030a in my drawer or for low investor, tda2030a is good sound for the PRICE )
I will use four IC 1:Tweeter 2:Mid 3&4:Woofer (Bridge) i.e. 18x2+35 = 70Watts per channel. (Please Note that TDA2030A works as power op.amp.) & Same for another channel. It would be better option then 2.1. tda2030a sounds good with correct grounding & good 8 Ohms speaker mounted on floor standing enclosers.
Calculate the project cost :=
12-0-12 5A transformer = xxxxx.xx
tda2030a x 8 = xxxxx.xx
& required Component = xxxxx.xx
OR
LM1875 (off-course is a winner)
18-0-18 5a transformer = xxxxx.xx
LM1875 x 2 = xxxxx.xx
& required Component = xxxxx.xx
Passive crossover with expensive inductors & capacitors.
For above two project, my choice would be tda2030a. BUT if I have money then I would go with lm1875 tri-amp.

U mean i have a 2.1 channel computer speakers. They cantain tda2030a and pt2353. Can i change tda2030a with lm1875???????????????????????????????????????????????????? with out any problem or distortion in sound???????/
plzzzzzzzzzzzz can u provide me best professional and 100% error free quality schematic for tda2030a single and bridge????/ and if pcblay out is there its wonderrrrrrrrrrrrr fulllllllllllllll? Thank u so much i like ur project. and i also wana make the same if u can provide me the best quality schematic. and plz tell me the speaker size for mid and tweeter i mean 8 ohm in 5 inch or 4 inch. and also size of woofer speaker?????????
Due to the pt2353 i think there is no zobel and i am not sure about diods but if they are as in typical application of tda2030a in datasheet can be removed with lm1875 becoz it is the only difference other than the difference in values of component in lm1875 and tda2030a typical schematic
I am not professional or expert member. I believe in DIY and that's a fun. 100% error free quality schematic is available in datasheet. STMicroelectronics's designer should be professional. And should not underestimate them. I am experienced member for tda2030a. Yet I will go following order.
1) Choose source (DVD Player) & Speakers
2) Build MONO tda2030a amplifier as per datasheet.
3) Listen & Listen.
4) I found sound vary speaker to speaker.
5) There is lot-off experiments for
---a) Input capacitor range from 0.01uf to 2.2uf
---b) Gain: 20 for tweeter & Mid, 32 to 47 is for woofer.
---c) As per datasheet page # 2 : C2 can be use 10uf to 47uf or more. But switching noise affects.
---d) Classic grounding. (Lot-off threads here)
---e) Good schematic is on page # 10.
6) Input crossover you can choose after listening your source several times.
I can post my schematic which is good for me.
