cool system i am running alpine type s speakers all around and a type x 12"sub in a ported custom built box with a kenwood headunit and planet audio 1000 watt amp beats hard especially for a single 12 i listen to rock and metal about 99% of the time, so 1 sub is all i need, u se to listen 2 rap and stuff like that more but cant stand that anymore so i cut down on the # of subs i have and went with a high powered single sub system to make it loud but clear for the faster paced rock/metal i listen toHey buddy you will be fine running those, I have them in my P5. All Alpine system as well I'll post it below
I got them in with no problems or modification really it was pretty easy just snap out the triangular cover piece and wire them in
System:
(2x) Alpine SWR-12D2 12" Dual 2 ohm Subwoofer (Type-R)
Atrend 12" Dual Vented Alpine Specific Enclosure
Alpine MRX-M100 Mono Block 1000w amp
Alpine CDE-W235BT Double-Din Head Unit
Alpine KTP-445U "Power Pack"
Alpine SPS-517 5"x7" Front doors (Type-S)
Alpine SPS-610 6.5" Back doors (Type-S)
Alpine SPS-110TW 1" Tweeter (Type-S)
Depends.
Yes, you MUST block low frequencies. Does your amp have a high-pass filter?
Are you using an active crossover?
If no to the above - go to Partsexpress.com and get 'bass blockers' to wire in.
