| Ignore the power claims of a amplifier. The only one that is of any importance is the rms power rating, in this case it was 50w x 4. That is the only real concern. To gain a difference in output levels that you would hear as louder, you need to double the power, in this case to 100w x 4 rms. Amplifiers are designed from the get go to handle increases in power upon demand. What you are proposing though is a waste of space, wiring and $. Keep it simple, if you think you need more power to keep up with the bass response, a larger 4 channel amplifier would be the way to go.
The speaker is only ever going to reproduce what it is given. Have a 50w amp, that is all the speaker is going to produce (unless the amp is underrated but even then generally it is not by much). The amp is not magically going to produce 1200 watts to try and keep up with the bass response.
The amp will only deliver what it is rated for at the impedence it is operating at. If your speakers are 4 ohm, look at the 4 ohm rms rating on the amp, that is what your speakers will have delivered.
Multiple amplifier set ups can and do work great. Is it necessary in your case, probably not. Two amps are a breeding ground for noise in most systems, it also takes more space to install them and more wiring to hook them up. That equates to a waste of $ that you could invest into better speakers to improve the sound quality of the system in your vehicle. |
