Hi Everyone,

I just recently replaced my SWR-1022D because one of the VCs was toast and i don't wanna repeate my mistake (if there was one in the first place). I think my problem was that i bridged my amp and i was giving my sub a full 1200RMS @ 4 ohms O.o

I'm always confused with the ohms and such and thought i'd ask somewhere where people know what they are talking about

so the sub has dual voice coil (2 ohms each) and the total minimum impedence on my amp is 2 ohms. In hindsight i probably should have bought the sub with the 4 ohm voice coils but too late now.

What i 'think' is ideal is to bridge the + and - on the sub (to get 4 ohms of impedence. If i bridge both + to + and - to -, i think that gives me 1 ohm and i don't think that would be good for the amp) and connect the other + and - to one channel on my amp. I've thought of bridging the amp but that would give me way too much juice (as i've done before to just the one sub. Sub handles 500RMS and bridging my amp would give me 1200RMS @ 4 ohms. If i use just the one channel, it still gives the sub 600RMS in theory. It does seem like a waste to just leave the other channel doing nothing but that's what i have to work with :P

If anyone knows if this sounds right or if they have other suggestions to 'optimize' my bass... please let me know. Thank you for reading.

p.s. another thing that's bothering me is my dimming lights. I've done the 'big 3 upgrade' (zero gauge wiring to ground engine to chasis, battery negative to chassis and alternator positive to battery positive), i've replaced my battery (old one was on it's last legs), put a 2 farad capacitor in and i'm still getting noticible dimming. Please tell me there is something else i can try other than replacing my alternator. i'm pretty sure it puts out 120 amps already and beefier alternators for a 1.8t jetta are rare and hella expensive.

Series the coils and run 1 pair of wires to the amp.....the 2 sets of connectors on the amp are internally paralleled in the amp so it will stay within it's normal operating range.

If you get another one of the same subs, wire it the same way and plug it into the other speaker connections on the amp.....for now the single sub will have to deal with the 1200watts......keeping the gain at minimum will help......

HTH

Awesome... thanks for the tip. So basically, exactly like this?...


with the amp bridged? I surely will have to keep the gain at a min.

And yes, i was thinking that i would go with the more powerful amp just in case i wanna put another sub in there. However, i don't think i wanna put in the three weeks that it tooke me to build a custom fibreglass enclosure lol. DIY post and pics comming soon. I must say, it turned out quite sexy.
