Negative and positive termanals not marked on speaker for instqllation does it matter?


It matters. Get a 9-volt battery and touch it to the terminals. When the positive side of the 9-volt is connected to the positive speaker terminal, the cone will pop out. If it pops in, then the positive side of the battery is touching the negative speaker terminal.

NOTE: A subwoofer should be strong enough to handle this. If you try this with a small speaker you can damage it!

What is the best way to connect two 4 ohm type-r


Connecting the speakers in parallel is the best route here. Parallel wiring is simply connecting the positive wires together and connecting the negative wires together. Then connect both positive wires to the positive output of the amp and both negative wires to the negative output of the amp. When both 4ohm speaker are connected in parallel the combined impedance is 2ohms. This particular amplifier has a damping ratio of >250 at 2 ohms compared to a damping ratio of >1000 if you connected them in series at 8 ohms. the damping ratio is simply the reduction of power transferred. (For future reference in order to get the maximum power transfer input impedance must match the output impedance.)

Which connections is the negative on these


most car stereo speakers have two connectors, one thinner and one wider. the wider one is typically the positive connection. to verify this, take a small 1.5v battery, and hold a wire to the negative and positive sides (it's easiest to use a battery case available at many electronic stores), connect the negative wire to the smaller connector, and tap the positive wire to the wider connector. if the speaker pops outward, then the thinner connector is the negative connector.
