[QUOTE="Trae, post: 8250531, member: 660546"] New to car audio, I am trying to learn and get a decent beginner kit set up. I currently own a 07' Chrysler 300, the following is my current set up: HU: JVC KW-av61bt Max power out put: 50w x 4 RMS: 20w RMS x 4 channel @ 4 ohms (no more than 1% THD+N) Amplifier: MOS-FET Equalizer: 3 band parametric iEQ Frequency Response: 40-20,000Hz Load Impedance: 4 ohms (4-8 allowable) Speakers: Kenwood Excelon KFC-X639 Impedance (ohms): 3 Frequency Response: 50-25k HZ RMS: 2-130 Peak Power: 300w Sensitivity (db): 89db @ 1W I will be running an amp and sub. I am currently browsing forums and reviews seeking a 5 channel amp that will sufficiently power 4 kenwood Excelon X693 6x9s (2-130 RMS / 300w peak) and a jbl 1600w series 12 dual voice coil in a ported box (given to me by a friend). My range is roughly 200-300$, I'm willing to spend a touch more if it will make an incredible difference and ensure the safety of my HU and speakers (spending less than my budget is always a + too). I have found 2 that look like they will work but for the cost and amount of power, seems like a waste? Infinity Reference 5350a RMS: 50x4 + 150x1 Peak Power: 89x4 Minimum impedance bridged: 4 Minimum impedance unabridged: 2 Best frequency response: 10-100khz THD: 1% Signal to noise ratio: 85db Kenwood KAC-7005PS RMS: 40x4 + 300x1 Peak Power: 104x4 Minimum impedance bridged: 4 Minimum impedance unabridged: 2 Best frequency response: 5-50k HZ THD: 1% Signal to noise ratio: 80db Think either of these are sufficient to run my set up without speaker blow outs and sounding nice?
