Hi-
I'm new....my son has a 78 Cordoba with a new (but cheap) head unit. Speakers are original and floating ground system and truly sounds awful- so I want to replace speakers.
Front has 3.5" on dash, Rear is 6 x 9s. want to add 5ch amp and sub in trunk and allow for EQ in future.
Looking at:
• Planet Audio AC1800.5 5 Channel Car Amplifier - 1800 Watts, Full Range, Class A/B, 2-4 Ohm Stable, Mosfet Power Supply, Bridgeable
(Power - 300 watts max x 4 @2-Ohms plus 5th channel 600 watts max x 1 @2-Ohms, 150 watts max x 4 @4-Ohms
plus 5th channel 300 watts max x 1 @-4-Ohms, 600 watts max x 2 bridged @4 Ohms)
• a pair of 4 ohm, 200RMS/400 max 6x9s for rear
• a pair of 4 ohm, 120RMS/300 max 3.5 for front
• 4 ohm Alpine SWT-12S4 1500W Max (300W RMS) Single 12" Sealed Subwoofer Tube
I planned on taking the single pair of RCA out of head and splitting them so I get 4 sends to amp. (also allowing for easy EQ addition later)
Using the amp's 5th channel selector to take MIX of Ch1-4 for sub input.
Questions are:
1. Are those speaker ratings OK for that amp? (I have seen too much conflicting info to understand whether spkr or amp need to have more wattage)
2. I understand the power for amp should not run with the signal send from head to amp- but can the sends run with the spkr returns to front?
I've only got 2 sides of the car for running wires...how would a professional split them up?
3. Does the amp magically know what ohmage the spkrs are? I do not see a selector switch on amp for 2 vs 4 ohms...
I'm guessing it can sense the impedance and pushes wattage accordingly?
If anyone has suggestions of what would work better with the amp or vice-versa- I'm all ears...
(BTW... his budget is under $500 for total project)
I appreciate any and all help, in advance! Thanks
