Need to know watt output for PB115M1. - Intermatic & Indoor/Outdoor Rain Tight Timer

Depends on what output your stereo is. If you underrate the speakers (speaker watts is less than stereo output), the unit will sound louder for a while, then you end up blowing your speakers with the excess distortion. If you overrate the speakers (speaker watts is higher than stereo output) the speaker will not operate correctly and the distortion can damage it also. Its best to get a close match. Slightly higher is better. It is important you know actual wattage output not PMPO ( Peak music power output) A lot of stereos are rated at PMPO. The higher number sounds great but in reality, the figure is the MAX output and by then the sound is distorting badly. Distortion ruins more speakers than anything else...

The radio has a heat sink as it has a amp built into it--about 100 watts maximum output---get someone with a DUMMY load and watt meter and see what it is putting out power wise--Most of the RCI have a variable control on the front for power output.

Without knowing make or model other than 600 Watts and pure sine output:
http://www.donrowe.com/user_guides/samlex/ssw_series.pdf
is for a series of pure sine inverters, yours should be similar enough to the 600 Watt version to be of practical use.

The Clarion APA2001 is rated at 400 watts maximum power output with a continuous average power output of 200 watts at 4 ohms.

Unless you want the same speakers for cosmetic reasons, you can get a pair of speakers from any Hi-Fi outlet. All you need to know is the max power output of the amp in watts for each channel, and the ohms it puts out. For instance if it says 8ohm 15 watts. You can get a speaker of 8ohms or higher, but not lower. And any speaker above 15 watts.
Actually you can get better quality sound from the speakers as the speakers they often put with these systems are rubbish in terms of hi-fi quality!
PS
Just had a look around the net and the output power in watts is just 8. Couldn't find the ohm rating but most are 8ohm. So any speaker higher than 8 watts will do the job.

13.5 amps is what you alternator puts out 625 watts 28ah.

Your generator/alternator has an output of 37 Watts @ 8,000 rpm ( 12v x 3.1 amps = 37.2 watts) all the best....BLASTUS

Hello sharky75,

That 1600 watt peak power figure for your subwoofer can't tell you what amp you need. You need to know the maximum RMS power the sub can handle. And you need to know the impedance (ohms) of the voice coil(s). JBL GT5 series subs have an RMS rating of 275 watts. The GTO series handles 300 watts. The Power series handles 400 watts. The GTi series handles 700 watts. Some are single voice coil, so the impedance is fixed. Others are dual voice coil allowing you to wire them for different impedance loads.

For maximum performance your amp should be able to provide at or near the same number of watts RMS into the lowest impedance at which the sub can be configured. For example, if your sub is the Power Series Model number P1224, it has dual 4ohm voice coils and can be wired to present either a 2ohm load (parallel) or an 8ohm load (series). You want to wire the voice coils in parallel for the 2ohm load and select an amp that outputs up to 400 watts RMS into 2ohms. The Orion Cobalt CO8001 is just such an amp. If you have one of the GTi Series subs, a better amp would be the JVC Arsenal KS-AR75 which outputs 700 watts into 2ohms.

Hope this helps.

Hi this is Compaqowner again NOTE: I know enough about home Stereos,and I am pretty sure to figure out 'power output' you take the total:in this case it takes in 110 watts total devide that by 2 so according to my math that is 55 watts (I guess this AKAI has a 55 watt amplifier) then you take the amplifier output (in his case 55 watts) and devide that by how many channels are being used,so in 5.1 DOLBY mode DVD movie,etc.(power to all 5 speakers) then it's 11 watts per channel,and in 2.1 stereo (power to the subwoofer,front right,and front left speakers only) it jumps up to a little over 18 watts per channel,again,I think?,when you find the answer,please let me know. Thank you for your time. Steve B.
