Hi all,
I'm currently in the process of trying to get my first product manufactured - it's basically a cooler with an audio system installed (we're currently hand-assembling them with off-the-shelf components and we've gotten great feedback from our customers). I'm here to ask for some guidance in designing the amplifier and pairing the right set of speakers to it. Hopefully this is the right community to help me out!
We're looking to use a 100W RMS amplifier and 2 6.5" speakers. Power supply is an 8 A-h lead-acid battery. Sound quality is important, but it must come at a good value.
The amplifier must have the heat sink, RCA/3.5mm inputs, and gain control on one face. The other 5 faces will essentially be surrounded by insulation (the amp will be recessed into a special compartment in the cooler). Will this cause overheating issues? Or is it not a problem, as long as the heat sink is exposed to airflow? Also, I doubt we'll be able to find an aesthetically-pleasing amp that meets our "one-face" requirement. So we might end up getting the housing custom-made, then buying the amplifier electronics. How would I go about finding amplifier electronics without a housing?
And what specs are most important for the amp? Here's what I have so far:
Power: 100W RMS/200W Peak at 4 ohms
Frequency response: 20-30k Hz
THD at rated power: <0.05% at 4 ohms
Damping factor: >500 at 4 ohms / 50 Hz
Signal-to-noise ratio: >95dB below rated power
Input impedance: 40 kohms
Output impedance: 2-8 ohms
Class: AB or D
Fused
CEA-2006 compliant
Anything I'm missing?
Sorry for all the questions, and thanks for the help!
Andrew
