It is time for me to upgrade!!!
But i need some help. I want a mono amp to run a sub of about 500/600 RMS power. Could you lot help with some suggestion of with one are good.
I thinking of about £180 for sub (12")and between £200/300 for amp. I had a 200 w RMS rockfosgate sub which i liked the sound of so prob keep with one of them but a more powerful version!!
Also i have infinity 505cs components. They are 75 w RMS so could u also suggest a amp to run these Are these powerful enough thou????
To start i am fully sound deading the car, but what else do i need to do. i got a good wiring kit already, except i will need a lower gauge power and earth cables. Do i need a power cap??? (i got a SXI C if it makes a difference, no Air-CON)
Should i have speakers in the back...if so i would need a 4 channel amp. Or should i keep it simple:-components in front and sub in back?
Thanks!
Adam

The kenwood amp..
SPECIFICATIONS AT 14,4V
200 W Rated power (4Ohm, 20 ~ 200Hz), 0.5%THD
400 W Rated power (2Ohm, 100Hz), 0.5%THD
500 W Rated power (1Ohm), 1.0%THD
1000 W Maximum output power
14,4V....what this mean i thought it was 12V
also the Rockford fosgate ub doesn't run at 1ohm, so that amp would underpower the sub ??
Any other suggests/recommendations plz

12" woofer
3" Voice Coil
Dual 2-ohm voice coils
Power range
500 watts RMS (250 watts per voice coil)
Peak power 1,000 watts
Dual 2 ohm voice coils wired in parallel = 1ohm.
When the engine is on the voltage will be around 14.4volts.

Calm down m8,
didn't mean to imply that u were wrong, i just didn't know it was to do with wiring. Thanks for clearing that up.
Anway would i notice a difference in quailty between say that kenwood and say an equivalent roakford amp (i know they are a bit more expensive, but is it worth it?)

i think you would hear a diff in quality, but it really depends on your budget.
for the money though, the Kenwood amp looks pretty impressive IMO.

What about this amp
ROC-PUNCH501S
Number of Channels: 2
RMS Power (4ohms): 125 W
RMS Power (2ohms): 250 W
Bridged RMS Power (4ohms): 500 W
Quoted Max Power (4ohms): 1500 W
Built-In Crossovers: LPF 50-250Hz & HPF 50-250Hz 12dB
Should get this opposed to the kenwood, to go this that rockford SUB?
What are the benefits. It cost £239.99. is it worth an extra £75

well you would have to wire the voice coils in series to get the 500RMS output. Would also be a cleaner signal, so yeh you could
