Alright, now this is my last product selection forum for a sub/amp, I SWEAR. But I was going to go with the Kicker ZX300.1 because I was told it was good and would run off of 8 gauge wiring, but then I found the Rockford Fosgate P325.1 and thought that looked good but it needs 4 gauge so I'd be spending the money for that. I have already picked out the Rockford Fosgate Prime R1L-1x10 that run at 300 watt rms. I think the RF is more aesthetically pleasing with the cover for the wire terminals but that's second to performance.


Here are some links:

just go with what you think is better.. everyones hearing is different... so what may sound good to one may not sound good to another..


also.. who cares if it looks good... if it performs thats all that matters (IMHO)

Yeah, I know it's performance but if it was a draw I'd go for the RF because of the cover. Is there an advantage for running 4 gauge compared to 8 at this low of power?

Alright, then running 4 to a d-block then to two amps with 8 gauge a peice would be bad?

The advantage of 4AWG vs 8AWG is based on Ohms law. For long runs of power or speaker cable the generally the heaver the better. Voltage drop across the cable is is base on the max. current draw of the amp or speaker as resistance will remain relatively constant.and source voltage should be relatively constant at 14.7V (engine running) or 12.2 (engine off). If you know the length of the power cable and the max. DC amp draw of your equipment here is a link to a nice article and calculator.

Oh okay, I was just going by what the manufacturers were telling me. The money I spend on the new 4 gauge will save me the money for the shop running the 8 for me. The 8 was too flimsy to go through the boot.

yes listen to whatever the manufacturers say :rolleyes:
Crutchfield also told me that. But I'm doing the RF because I guess it comes with a certificate that says the manufacturer tested it to work at 390 watts at 2 ohms and 240 at 4 ohms.

Both are great amp manufacturers. I have always ran kicker and never once had a problem. I currently use a t600-4 fosgate mid amp and it is great. I would just pick whichever one looks better in your car.

Kicker does the same or at least use to, I have a kicker 3004. that's rated at whatever the stock ratings are, but put out almost 20rms per channel more then the initial ratings... This is about a 4 year old kicker amp... so not sure what they do now or how they are in quality but I've been a huge Kicker fan when it came to subs anyway!

I plan on doing the dual RF prime 10's and late buy something larger in a ported box that I can swap out when I don't need cargo space.

Ordered the Rockford Fosgate amp for 135 today. Will order the subs next week after my paycheck.

good choice.. if I didn't have my JL 1000/1 I would go with the RF amps.. really nice in design, reliable and put out more than rated!

RF ftw.

I'll post pics after it's installed, with the cover i should be able to make it so you see minimal to no wires
