I have the Alpine amp, I was thinking of going with 300/4 instead of the F540. Do you think it's worth it?

I have DLS UP6 (150wrms) components in the front and Eclipse SE8495 (80wrms) 4-way 6x9s in the back. I have a JL 500/1 pushing my sub and I like how it sounds. So I was thinking the maybe the 300/4 could do a better job pushing my speakers.

doesnt a 300/4 push in 300W to each channel regardless of impedance, in which case thats ALOT of power especially for the 2 rear channels

no man it's 75wrms per channel at any impedance between 1.5 - 4ohm. however it has better specs
THD... Alpine 0.08% at 4ohm vs JL 0.03% at 4ohm
S/N ratio Alpine 100dBA vs JL at 108.5dBA
Slew factor Alpine >5 vs JL > 25

oh OK.... shows how much I know................ but in all honesty id say if youve already got the Alpine, then use the Alpine............ I mean Ive had 3 V12s (still running 1 now) and ive loved um............ mine were the newer ones except 1 (running MRD-M605, have a MRV-F345 sitting around, and had a MRD-M301), but the quality is nice

jl has a better x-over (12 or 24 db per octave, hi lo or band pass, 50 to 5000 hz crossover points). power is comperable. sq is comperable. unless you are going to actively bi amp your dls speakers with the 300/4, i wouldn't change the amp. jps

no biamping planned, and I have crossovers in my deck 6,12,18,24dB/octave, high pass, low pass filters. I just thought maybe if the JL has better SQ due to low THD, high damping factor and bigger S/N ratio it might be worth it. But if it's comparable... I think I'll leave it alone then. Thanks for your input

well it sounds like your mind has already been made up for the 300/4, also its nice to have matching amps
