are you planning to amp up any speakers aswell, or just the subs? as that will decide on how many channels you need on the amp

The subs look to be dual 4 ohm, so that gives you good flexibility on how to run them, i.e. in series or parallel

[straughton]

Just the subs. If i.wanted to add updated speakers later i could just buy another amp? Cheers for the help

unfortunately, "get the most", and "budget", dont always come hand in hand!

without looking into all the hundreds of makes, models and prices, so sticking with audiobahn, one middle ground option could be looking along the lines of this, in terms of 2 channels, and 2 ohm rating

http://www.amazon.co.uk/Audiobahn-A8002 ... B004L6IKYC

As the subs are dual 4 ohm voicecoils, each one can run at 2 ohm in parallel, or 8 ohm in series.

The less the ohms, the more power, but this will put more strain on the amp. In theory there is less stability (or SQ) at lower Ohms, but depends what you are after really.


there really are loads of options, you could run all 4 voiecoils in parallel to give 1 ohm stable, but not many amps will support this, and will cost lots more.

Best budget option could be to run a combination of voicecoils in series / subs in parallel or vice versa to give 4 ohm, then any mono amp at 4 ohm will suffice.

other than that its a case of choosing your brand and budget!

Thanks mAte. Iv already got a shitty fusion amp from my old system what specs are:

69 Watts RMS per Channel @ 4 Ohms and 1% THD+N
92 Watts RMS per Channel @ 2 Ohms and 1% THD+N
180 Watts RMS Bridged @ 4 Ohms and 1% THD+N

Max Power Rating: 300 Watts
THD @ Rated Power 1kHz/100Hz: 0.1%
Channel Seperation: 50
Frequency Response Hz (-3dB): 10Hz - 40kHz
Signal to Noise: >90
Variable Low Pass Filter: 6dB/Octave
Variable High Pass Filter: 6dB/Octave
Input Sensitivity: 0.2-8V
Input Impedance: 20K
Fuse Rating: 25A
Could i use this amp as a source for my front or rear speakers?

Shameless plug coming - I've got an Alpine MRV-F405 4/3/2 channel amp I've just pulled from my tubby, which I'll be listing for sale on here later today hopefully.

You got the other one, the F407. This thing was fully loaded with all manner of noise boxes, which I've slowly removed. A 60kg weight saving isn't to be sniffed at

It is a bit shocking.. I'm sitting on my hands so I don't buy this one as well. I think my 2 channel one is good.

Any other alpine stuff in the car.. Other than amps??

Only a huge fuse in a holder and the two (yes two ) head units (CD/EQ and CD/Tuner). which are also being pulled and consolidated into one unit, leaving room for DIN gauges

Drop me a PM if you want, so the OP can have his thread back
