Installing two amps

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!

This amp can supply 50 watts rms (continuous) at 4 ohms into 2 channels, or 75 watts rms (continuous) at 2 ohms into 2 channels.

Your best bet will be to wire 2 subs in parallel to the amp. Each sub should be rated for at least 300 watts rms at 4 ohms. This will give you a total impedance of 2 ohms, and your amp will put out 600 watts rms at that impedance. That way, each sub will receive 300 wats rms. I would not recommend wiring subs in parallel, as you will need two 1 ohm subs at 300 watts rms, which are harder to find and will be more expensive. A parallel circuit is the most efficient way to do it.

Specifications Power Output: 100 Watts RMS x 2 channels at 4 Ohms ≤ 1% THD+N Signal-to-Noise Ratio: 80 dBA (reference: 1 W output) Additional Power Output: 200 Watts RMS x 2 channels at 2 Ohms ≤ 1% THD+N
400 Watts RMS x 1 channel bridged at 4 Ohms ≤ 1% THD+N THD+N (Distortion): <0.25% (reference: 1 W output) Frequency Response: 20 Hz to 20 kHz (-3dB) Maximum Input Signal: 5V Maximum Sensitivity: 100mV Dimensions: 14.37 x 9.72 x 2.5 (365mm x 247mm x 63.5mm)

I believe these are 4ohms, if so buy a 2ohm stable monoblock amp, that puts out 250-300 watts RMS, and connect your subs to it in parallel, don't pay attention to peak watts, look at RMS watts, or continuous watts. If they're 2 ohms, buy a 2 ohm stable 2 channel amp that puts out 125-150 watts RMS per channel, and 250-300 watts total or bridged RMS output. And connect them normally, on sub per channel... hope this helps, as far as brand recommendations, MTX, pioneer, Alpine, Kenwood... Good luck

Hello rjmiller4039,

Although amps with 5 channels are pretty rare, you can get one. Alpine, Boston Acoustics, Infinity, JL audio, MTX, and Polk all have 5-channels ranging in price from around $350 up to around $1,000. The Alpine PDX-5 will output 75X4 watts RMS for the front and rear stereo channels and 300 watts to the mono sub channel. It is priced at $599.99 at Crutchfield.

Hope this helps.

Here are some specs:

4800W Max, High-Current 2-Channel Car Amplifier

RMS Power Rating:

• 300 watts x 2 chan. @ 4 ohms
• 600 watts x 2 chan. @ 2 ohms
• 1200 watts x 2 chan. @ 1 ohm
• Bridged:
  • 600 watts x 1 chan. @ 4 ohms
  • 1200 watts x 1 chan. @ 2 ohms
  • 2400 watts x 1 chan. @ 1 ohm

Max Power Output: 4800 watts @ 1 ohm

this is the web site I got the specs from

Hello drsubhakar26,

JL W6's will perform well with from 150-600 watts RMS. W7's with from 150-500 watts. Less expensive Alpine Type R's work OK with from 200-500 watts RMS. Either of the brands will sound good. None of them will perform to their full potential with 300 watts RMS. Powering any sub with a 2-channel amp is a compromise. A monoblock is more efficient.

Hope this helps.

Hi Trim God,

 

I do not reccommend that you push the Pioneer speakers over 100 watts.  The jenson will already drown the car with bass through your pioneers so much you will want to turn off the bass boost when playing some low bass hip hop songs. It changes from one venue of song to another, so I just keep the jenson bass boost off and use my head unit to adjsut the sound to fit my listening prefences. I am telling you man, you will be blown away .  Hook up the pioneers straight to the Channels,. do not bridge.  I put Subs in my truck though.  I used the Pass output to send the audio to me Jenson 2 Channel 600W amp. I drive one 10 inch enclosed JBL Class A/B Sub. I bridged the output of the 600 W amp to the 10 inch sub  in my Z28.  The pioneers never get drowned out.  I did smoke my 2 channel Amp one time. and also took out a MTD 10inch sub. I am talk shooting flames and smoked the whole car up. I think if you bride the XA4150 to the pioneers, you will have the flaming smoke problem in no time.  

With a single 4-ohm subwoofer, usually the best choice is a 2-channel amp that can be bridged to a single channel. In your case, the sub is rated for 1000 watts. Not many amps are rated for that kind of continuous power into a 4-ohm load. Kicker doesn't list a minimum power rating, which isn't unusual in subwoofer specs. Depending on your budget, I'd look for an amp rated for 300-500 watts minimum; the higher, the better, up to 1000 watts. Most amps will have several power ratings, based on the load impedance and number of channels driven. A typical 2-channel amp might be rated like this: 150 watts x 2 channels at 4 ohms 300 watts x 2 channels at 2 ohms 500 watts x 1 channel at 4 ohms. The power rating you'll want to look at will be the 1-channel, 4-ohm rating. You can look at mono amps, too, but in the power ranges you're looking for, a 2-channel amp will probably give you the best value. However, if you can find a mono amp with a high enough 4-ohm power rating, it would run cooler and might last longer than a 2-channel amp with comparable power. When looking at mono amps, you'll find their highest power output will be at 2 ohms or 1 ohm; make sure you're checking the 4-ohm rating when making comparisons.
