C8: Please Help With Aftermarket Stereo Install - Upgrades…
‘24 C8 1LT and simply adding 10” sub while remaining 10 speaker Bose remains stock for now. Amp has speaker level inputs, so planning to just tap wires at stock amp, but exactly
which wires to tap would be appreciated!
Equipment:
-Alpine MRV-M500 amp
-Pioneer TS-Z10LS4 10” sub
-Custom built 10” footwell sub enclosure
2 Questions:
-Where is a good ground if I mount the amp behind the passenger seat?
-Best way to get 4 ga power cable from battery into passenger compartment?
Open to any tips & suggestions for getting this done the most efficient way! Thanks!
