What amp would be better to use with what speakers/sub? I have a KAC-7202 kenwood 920W maximum power (150wX2 RMS, 4ohms) (230wX2 RMS 2ohms) and then the other amp I have is a Alpine MRP-M500 mono power...


I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!

I have one alpine type R 12 SWR-12D4 1000 watts rms-3000 watts peak, and I have it hooked up to the Alpine MRP-M500 mono power amp (500w RMS+1 at 2 ohms and 300w RMS+2 at 4 ohms) I have all great...


I usually run an extra pair of RCA's when I do an install. This way if you have a problem with one you're already set or if you upgrade you won't have to tare you car apart again.

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.)

I just wired my alpine type 12 4 ohm subwoofer to two ohms by putting the two red runners in the positive terminal and the two black runners to the black terminal and hooked the wires up to the outside...


If you have the Alpine SWR-1222D, that's a dual 2 OHM Sub. So, the way you have it hooked up to the amp ,it's 1 Ohm, and unless your amp can safely operate at 1 OHM, you are better off connecting the voice coils in series so the amp will see 4 OHMS. The link below will show how the connections are made to the amp. Look at example # 1.

    Need to know


    I'm assuming that you have an amp that you are installing these to. Its always tricky installing subs of different impedances. Do you have the model number of the amp that you are hooking them up to.
    Most likely if you have a 2 channel amp, you would connect one sub to each channel as most amps can handle a 2ohm load in stereo, but don't bridge the amp with these two subwoofers without specific instruction from someone with experience as you will most likely overlad the amp. If you can be more specific with your set-up I'd be able to assist you more.
