My system consists of:
Car: 1985 Pontiac Firebird
Head unit: Pioneer deh-1300 45X4 cd player
equalizer: Pyramid 7 band eq with sub level control
Amps: Jensen 300watt 2 channel amp 2X150 (bridgeable)
Pyramid 800watt 4channel amp 4X200 (bridgeable)
Pyramid 300watt 4 channel amp 2X60 2X90 (not bridgeable)
Speakers: factory 4X6's in the dash (plan to upgrade soon need $)
Pyramid 6X9's in store bought boxes in the hatch area 300watts max each
2 X Pyramid 10" subs 500 watts max each
1 jensen 10" sub 225 watts max
setup: I'm using the jensen 300 watt amp to power the 6X9's
The Pyramid subs are running off the 800 watt amp, I have the channels
bridged into 2X400 watt channels
The Jensen sub is running of the pyramid 300 watt amp (one of the 90 watt
channels
I have a second battery in trunk area under my sub box, along with my amps. My box is custom built and has 2 tubes running through it with fans to provide air circulation around my amps. The box is sealed.
My first question is: I just have the second battery wired in such: first battery + connected to second battery +, second battery + connected to all amps +. the first battery is in the factory location grounded to the alternator bracket(standard factory grounding. The second battery is grounded to the body in the back of the car, and al the amps are grounded to the negative terminal on the second battery. I have two fuses in the wire connecting the first and second battery, one just off of each battery. Is there any problem with this set up, or is it fine? There is no noise in the system except a slight hiss caused by the eq. which i have narrowed to grouding problem, but haven't had time to fix yet.
My second question is: can I hook up the 2 90 watt channels on the pyramid 300 to the one sub woofer. Ie channel 1 + to sub positive and channel 2 + to sub positive. and negatives done the same way?
I would appreciate any other advice you could give me also.
thank you
