For a bit of fun and to see what can be achieved, I want to build a compact busking amp using two Jenson MOD5-30 8Ω speakers which I have kicking around. The speakers have a rated power of 35W and I was thinking of using them in parallel to give me a 4Ω load. Power will come from one (or two) Ritar RT1250 which is a 5.0aH, 12V SLA battery.
I was thinking of using a TDA1524 in a pre-op stage, which should work well at 12VDC and give me controls for volume, balance, treble and bass. What I can't decide upon is what Op Amp to use. Should I go for a dual channel op amp and try to bridge it (such as the TDA1554 2x22W power amp), or is there a decent single channel op amp I could use?
I want to get maximum power fully exploiting the potential of the two drivers, even if it means only getting an hour or two of play time.
Any thoughts on what op amps would work well?
