Yo, currently piecing together my car system and doing the homework. I'll say upfront it's nothing top notch and I'm not dropping a ton of money, but I would certainly appreciate any tips and opinions, and technical support. This is the general idea and would like some help to make sure everything fits.
I'll be running 2 amps, 2 sets of component speakers(4 speakers), and a single 12" sub. I have a 4 channel amp left from my old system and another 4ch my Dad gave me from his old one.
Pieces are.
Amp/Component Speakers
Legacy MOSFET LA-688
RMS @ 2ohms 4x55
Powering..
Infinity Reference 6020cs
RMS 2-90
Impedence (2ohms)
Amp/Subwoofer
Blaufunkt GTA 4
Bridged at RMS 2x170W at 4ohms.(just using one bridged channel, other left open)
Powering
Kicker Comp 07C124 OR Rockford Fosgate P1S412
Both are:
RMS 50-150
4ohm
Reciever
Pioneer DEH-P4100UB
Questions:
1. Does everything add up correctly, ohms, RMS etc matched correctly? Will the 170RMS bridged channel really hurt a 150RMS sub?
2. Purely opinion, which sub would you go for, both had great reviews, similar specs, but crutchfield is running a Buy One Get One Free on the Rockford Fosgate, a nice option if I ever choose to run 2 subs, but Kicker is a great brand?
3. Would a low powered system like this cause any problems on the alternator or require an upgrade or extra battery? Edit: Chevy HHR 08
I'll be learning from my Dad this time how to do the install, but I need to do the homework first. Looking forward to any help, thanks guys.
