DB4.5 4/3/2 Channel Class D Bridgeable Mini Stereo 12v Power Amplifier 920w Verified RMS Power Output

World RRP: £185.99


Product code: DB4.5

The DB4.5 is literally the Swiss Army Knife of amplification. It’s a tiny size. It can run a pair of subwoofers. It can run 4 speakers. It will work to low impedance. It has a versatile BPF enabled crossover. It'll bridge up on one side and run a woofer or woofers and then on the other side it'll run a brace of speakers. You name it the DB4.5 has it covered because this is the future of amplification. It's the latest smt chipset and Class D topology delivering ridiculous power and control in a size that just will leave you speechless. Sound is powerful, open and clear. If you didn't know it was Class D you wouldn't tell - this really is a great sounding amplifier with a tonne of power.
